Are you ready for Mazda's sparkless ignition engine?

>>17674969
And these engines can easily be tuned to take a variety of fuels......

Wonder if this is why they've been so secretive about future rotaries?

Link ain't working, but I have read a bit on this earlier, and I am really interested to see how this is going to work out in real situations. Had it come 5 years earlier there is a good chance we'd be looking at the future of auto-engineering quite differently

>>17674986
AFAIK its been around for awhile, some F1 teams using the tech for the last few years, it just still a few kinks in working it out as evident with the failure of Honda's engines during this season.

A turbo with a boss electric motor attached. 48 volt architecture will help facilitate. They are really good for boost at low RPM and transient response situations. Couple it with a regular turbo sized for good top end and you have naturally aspirated throttle response with turbo motor size and efficiency.

>>17674969
Still unsure how this works, I'll have to look into it further. I had always thought that having a piston that could remain at ignition temperature would merely burn the fuel upon touching it, making spark plugs obsolete. I'm aware that running temp that high would absolutely destroy longevity and likely warp the components but a guy can dream

>>17675106
I think it's a little more complicated, but it involves a different injection scheme and likely a specific shape to get the whole thing to detonate at the same time. Also with gasoline you have to keep the the explosion limited to a low order detonation (heaving, slow explosion) vs a high order detonation (super sonic, knock) to keep from destroying the engine.

Lithium mining itself isn't a big impact on the environment.

It's all mining and all material importing. New construction in itself literally destroys the planet. Toxic metals brought to the surface, smog pouring out of diesel ships, oils from oil sands made into all those plastics cars are full of...

If you want to be green you forge an efficient engine from recycled metals and put it in an old rolling shell

Assuming 100% conversion efficiency, you'd need 6.482E11 acres to meet that need. Also remember this only works for about 12 hours a day and will NOT work at 100% conversion efficiency, or 100% storage efficiency. It is also expensive and harmful to the environment for both photovoltaic cells (rare earth mining) and mirror collector plants (chromium and nickel mining for mirrors)

electric vehicles are toys for the a rich minority. they are not our future.

in the future, the only electric anything you'll be taking will be the electric bus/train that the city already accounted for in its needs. maybe even a small self-driving electric taxi. your personal transport will most likely be a car or motorcycle more or less like any available today, maybe with self driving luxury features or a very weak LPG/electric hybdrid powerplant. only there will be fewer on the road and fewer people with personal transports because tax incentives, insurance rates, economic hardship, and better urban planning will make taking increasingly advanced public transit increasingly attractive, and milennials are already on board with the idea

Solar as a means of primary power is stupid. First it only works when the sun is out. Second, The thermal efficiency that solar panels produce when they are over 130F is horrible. In states like florida and Texas where its easier just to plant mirrors in a array you have the issue of efficiency of land use. However as supplementary power it would work fine.

You're still collecting energy for half the day and then parceling it out over the evening. You're not collecting new energy over the evening, you're just saving three of your six KWh/acre for later. That means you have to double the size of the plant in order to get the same power a plant half its size would produce during daylight hours alone just to keep up that production at night. Given, peak hours aren't at night most of the time so you can get away with less output at night but you're still losing a shit load of your collected energy during storage.

>>17674969
You mean a diesel?

>>17674969
Yeah. Newest generation gas turbines today operate at 60% thermal efficiency, and the fuel didn't even need to be shipped to a refinery and back. Don't toss them into the wind so soon.

Electric turbocharging and freevalve are very expensive. Economy of scale will bring costs down a little, but just look at the rising costs of base model vehicles. This is a bigger jump than carbs to fuel injection, or even from SOHC, to DOHC, to VVT. It's a big deal and I wouldn't expect them to take over unless the car market shrinks.

HCCI, by itself, will replace most car engines of the the future and most will be hybrids. But it will in no way replace the entire EV market, especially in cities as they crack down on smog. Also consider places were fuel is expensive like yurop.

>>17676529

I agree. The RF is a wonderful, wonderful car, but that price gets outrageous for what is ultimately carrying a base Mazda 3 engine. Even the standard Miata could stand to start off 2 - 3 grand cheaper.

The average car figure is dragged down by trucks that are exempted from MPG requirements. Passenger cars are closer to 30%-35%. Skyactiv is 40%, and Mazda is aiming for 60% with HCCI. Then they'll be combining that with hybrid tech borrowed from Toyota.

>>17682137
20% is outdated, we can already achieve 40% right now without HCCI and camless design. 60% is perfectly achievable.

HCCI has not been as widely implemented as spark ignition or diesel injection. It is essentially an Otto combustion cycle. HCCI was popular before electronic spark ignition was used.

So it's old news, basically.

You are both kind of right, the 40% efficiency is the peak efficiency, wich usually is at like 60% power.
The 20% figure is the efficiency you get in the average commute.

That is why tiny engines get much better mpg than big engines.
These tiny engine work closer to their maximum efficiency.

So if I'm understanding this correctly, we're getting high-efficiency gasoline engines that deliver on performance and throttle response, with the drawback of needing to employ finicky heating systems for the engine?

That sounds pretty good to me, especially if it's already being implemented in some existing f1 engines. If they make a GT high-ish horsepower trim of the Mazda3 with this, I might pick it up.

The only reason higher-octane fuels are used in performance engines is because they resist predetonation. With a compression-ignition engine, you NEED it to detonate without a spark.

>>17686752
If I got the basic idea of it right he homogenised the charge after the carburator to enshure a complete combustion, leaned it out to a point where it usualy won´t even ignite anymore and made it combust with spark ignition due to high intake temperature and boost anyway.

A HCCI works a little different

>>17674969
>look we made a gas engine run like a diesel

>>17690599
I'm just glad the japanese keep on trying to think outside the box over the years. Sure, they took a chance with rotary. You have another company that put in huge amounts of capacitors to capture all the waste energy that batteries cannot use up thru recharge due to the surplus occurring all at once. There's skyactiv that was better than other methods. Then Toyota led the way towards fixing the problem with direct injection having the intake valves clogged with carbon which top tier gas doesn't fix. And now HCCI is coming out as another mass-production attempt to improve things.

>>17682771
making memes, the glorious days of MS paint memes are long gone, replaced by the Wendy's twitter account and unironic "hail corporate" instagram models.

>>17690599
Diesels don't combust like HCCI. Diesels still have a flame-front during combustiom and are not perfectly premixed. In HCCI the fuel ignites evenly, everywhere in the chamber, at the same time. In terms of NOx, diesel is like drinking shit water out of a sewer and HCCI is like drinking out of a bottle.

>>17674969

I'm glad they are trying to advance the technology by enlisting adventuresome and risk-taking customers to help them fund additional development. If it extends the future of ICE, then I like it.

Mazda continues to show the industry how it's done.

Everyone else has been investing in STUPID HEAVY ev's that simply move the pollution some place else (while creating new sorts of pollution with their production). And putting turbos on everything that simply game the mileage rating system.

Meanwhile Mazda has been making their cars LIGHTER, exploring the upper reaches of high compression, doing really interesting things with electrics like eloop, making lock-up torque converter automatics that both don't suck and done need 15 gears....

Total lifecycle I have no doubt Mazdas way of thinking is actually much more environmentally friendly.

>>17692897

Mazda's i-ELOOP system uses a supercapacitor to perform brake energy regeneration in regenerative braking applications. The amount of energy obtained during braking occurs at a rate far greater than the battery's ability to store it. Supercapacitors are able to accept a charge rapidly. The charge stored in the double-layer supercapacitor is used to power car electrical systems, including the headlights, the climate control and the audio. It could even be used to recharge the batteries.

>>17694978
>The amount of energy obtained during braking occurs at a rate far greater than the battery's ability to store it.
A Tesla Model S can charge overt 150 kW into its battery for extended periods of time, so lets assume 200 kW peak.
200 kW / 0,8 generator efficiency = 250 kW
250 kW is more than enough for most braking situations.

Not even mentioning LiFePo or LiPo or LiGraph batterys wich can charge even faster...

>>17694997
It's not only about how much power it takes to charge a battery pack. It's about how much of the power is retained from the energy that emters the pack from regenerative braking. Capacitors store it all. Their main problem is poor energy density as compared to batteries.

>>17696437
LiIon Batterys have a 98% efficiency, wich is the same supercaps have.

>>17696485
But you can't discharge them 100%, unless you want a brick.

>>17696560
Why would you do that anyway?
At the point where the supercap is empty, the LiIon has 80-90% left.

>>17696587
But a super cap would last longer, which would be good for a regen system.
" In the supercapacitor, energy is stored electrostatically on the surface of the material, and does not involve chemical reactions. Given their fundamental mechanism, supercapacitors can be charged quickly, leading to a very high power density, and do not lose their storage capabilities over time. Supercapacitors can last for millions of charge / discharge cycles without losing energy storage capability."

Mazda fan, RX-7 owner, Miata owner, Nissan Leaf owner, and Prius owner here.

My Nissan Leaf gets 115MPGe, meaning it can go about 115 miles on the equivalent energy capacity of one gallon of gasoline. Even if you take into account grid losses (Estimated at 6.5% in 2007), electric motors and batteries not being 100% efficient, the Nissan leaf is still travelling much much farther than a Skyaciv X engine is off of the same amount of energy. And that 115MPGe? Thats with the EPA's heavy-footed driving style that achieves 3.45 miles per kWh. The way I drive my leaf, I get between 4.2 and 5.2 miles per kWh, raising that 115 MPGe much higher.

>B-but lithium is bad!
Think about how much energy was spent creating the gasoline your car burns, transporting it to the gas station, pumping it into your tank. Has anyone ever considered the environmental impacts of gasoline production and transportation when comparing gasoline engines to electrical ones? Not on /o/.

>B-but most grid power is produced by coal plants!
An interesting and in depth argument, indeed!
More on this in a second...

>>17702592

>B-but most grid power is produced by coal plants!
An interesting and in depth argument, indeed!

Let's start by figuring out how much carbon is output by burning coal. According to Energy Information Administration (EIA) research, emissions range from 2,791 lbs per short ton for lignite coal to 5,685 lbs per short ton for anthracite coal. However, the coefficients for the coals that are primarily used in electricity production, bituminous and sub-bituminous are 4,931 and 3,716 respectively. Let's take the high-end = 4,931 lbs of CO2 per ton (2000 lbs of coal).

That works out to 2.47 lbs of CO2 per lb of coal.

How much electricity does a pound of coal make? According to numerous sources, 966 lbs of coal produces 876 kwh (kilowatt-hours). So 1.1 lbs of coal per kwh.

Using the Nissan Leaf as our average electric car, the EPA quotes it as using 34 kwh to move 100 miles. Or 34 kwh x (1.1 lbs of coal/kwh) = 37.4 lbs of coal are required to move 100 miles. Or .374 lbs of coal per mile. So .374 lbs of coal x 2.47 lbs of CO2 per lb of coal = .924 lbs of CO2 are emitted to move the Leaf one mile.

Hows does that compare to a dino-juice-burning automobile? The EPA says that a gallon of regular gas (not diesel) produces 19.4 lbs of CO2. Take a typical car that gets 20 MPG and that is equal to .970 lbs of CO2 per mile.

The EV wins, barely, against a 20MPG shitbox. But wait. This is all assuming that :
1 : Electricity is produced by a coal fired plant using coal on the dirty side of things, and none comes from hydro, solar, wind, or nuclear (Unlikely)
2 : Gasoline springs into existence out of nowhere, with no energy cost to produce, transport, or store it
3 : Electricity is produced exclusively for the EV by burning more coal during its charge time (This is not the case)

Answer 1 : Most places have some nuclear plants and some hydro plants in addition to coal or gas fired plants. Some places even have solar and wind power.
More later in a second...

Answer 2 : Gasoline requires energy to produce, transport, store, and pump, making the true amount of energy per gallon (Once you subtract production and transport costs from the energy in a gallon of gas) much lower.
Answer 3 : Most EVs are charged during off-peak hours (At night) when there is an excess of energy in the grid. During off-peak hours, electricity is produced for the sake of availability. Energy that is not used simply disappears. Increasing demand during off-peak hours means this wasted energy is now used.

The end reality? An EV charged by the worst of power plants (Old coal plant using inefficient coal) produced about the same pollution as the most efficient gasoline cars (Prius).

I live in Alabama. We have one nuclear plant and many hydro dams. Hydro only produces 6% of Alabama's energy, and nuclear is about 15%.

But I don't drive a Leaf for the environmental savings. In fact, I don't give a rats ass about the environment. I have an '84 RX-7, and a '94 Turbo Miata. I drive the Leaf as a daily driver because it is hilariously cheap to fuel and maintain, while also being a blast to drive at low speeds due to the torque. Most EV charging stations in my area are free to use as well, further reducing the cost to drive.

Ironically, the same people who hate coal also hate the only alternative : Nuclear. If liberal fags would let us build more nuclear plants, things would be even better for EVs.

Oh, and I forgot to mention. My leaf was only $6000. For a 2013. With 40k miles. And a healthy battery.

Oh, I didn't even know about the Mazda2 dorito EV, seems kinda cool.
but are they planning something for real? Because Mazda wouldn't be the first, not the last, to patent something and then do nothing with it

>>17703500
They need to be if they aren't already.

Mazda has purchased the Hybrid Synergy Drive rights from Toyota, so they have everything they need to build a Mazda Prius right now. They also have the Mazda 2 EV in Japan, and those patents.

I wouldn't be surprised if they don't make a dorito REx, but I would be very surprised if they don't release a full EV soon.

Its valid for coal station

>>17703608
Not him, but I think gasoline travels a lot more than coal to reach its final destination.

An oversimplified travel plan for oil and coal:

Oil:
Extraction > storage > refinery to become gasoline > storage > capillary distribution to pump stations > car fuel tank to become energy

Coal:
Extraction > storage > processing plant to become usable fuel > power plant to become energy

While the coal trip doesn't look that much shorter, you have to consider it's moved in great quantities all at once, with fewer trips and bigger means of transportation, whereas gasoline is moved in bulk up until it's being refined, then it's just a billion trucks going back and forth between the storage and every single active pump station.

I don't know, I'm not an expert, but the coal trip seems cleaner to me, even assuming they use identical vehicles to transport gasoline and coal as long as they can both be moved in great quantities

>direct injection is the worst 2010s meme.
Like many inventions, they get rushed onto the market to cure one thing, but have unknown (at the time of invention) or unforeseen problems. Purely Direct Injection engines will almost certainly be replaced with a variation that continues to directly inject, but will also atomize some fuel at the intake valves to clean them.

Otherwise, direct injection engines probably need port injection cleaning to be done at one of the scheduled maintenance intervals.

It's one of those ad-hominem attacks. They are unable to refute the info, so they attack the person in order to stop or derail the discussion. If they can censor or intimidate you with such bullying tactics, then in one sense they win.

>>17703535
>What about the jobs
They're being replaced (e.g eliminated) by increased efficiency of existing workers. If you want more people to be hired, then there needs to be a law against efficiency. Or at the least, cutting out the middleman is no longer an option as that decreases jobs.

Concentrating profits into the hands of the few is also decreasing jobs. If a product is sold at 100 monetary units, and 90 of the units goes to only one person, then all the other people involved with that product must make a living from the 10 units. That means prosperity is decreased than if no one person takes more than 10 units of profit from that product.

Well, to be fair to the car makers, direct injection solved the EPA and EU requirements for increased MPG. And the new problem of clogged intake ports is a problem that belongs to the car owner. If anything, this problem would be solved by dealer servicing or 3rd party auto services, so it represents additional profit to the dealer network.

Unless the car owner uses a home remedy such as CRC Intake Valve Cleaner which as 30 times the concentration of PEA cleaners in Costco gasoline.

This is why new Ford engines are dual injection. Port for low revs + cleaning, direct for performance

>>17707500
Ha, ha, waiting for volkswagon to try:
If {EPA MPG test}
then {use direct injection}
else {use dual injection}.

There is an answer, it loses energy, albeit at an extremely slow rate. The problem is it's not socially/politically viable.

More and more you are proven right. Battery tech lags behind other tech, and top tier batteries use expensive rare earths.
Batteries utilizing radioactive isotopes, ie a nuclear battery, are the future

America haters will buy a bunch of them and sprinkle the isotopes all over the grain and agricultural areas of the country. The root of American military might using the Treasure** system is its industrialized agricultural system. Topple that and america will wane.
