Bring it to the USA! Seems great coupled with the hybrid system. Would be a great competitor in the fuel efficient crossover segment, I'd buy it!

I hope more car brand will be able to develop this type of engine.

Skyactiv-G = Gas Skyactiv-D = Diesel Skyactiv-X = Mix of the two

Does it have port injection to keep the valves clean?

This explanation of both gas and diesel engines seems confused, based on my academic knowledge. This came from a Marketing Dept who didn't even talk to the engineers and throws around silly terms they think will impress. The fuel in a diesel engine actually burns slower, indeed only as fast as it sprays into the cylinder. That is designed to last thru about 90 deg crankshaft rotation. That keeps cylinder pressure and temperature more constant as the piston descends, making it closer to the ideal Carnot Cycle. That goal was even stated by Rudolf Diesel in his 1890's patents, per wikipedia article. The liquid droplets burn with a diffusion flame around each one, why a diesel can run much leaner overall O/F and doesn't need to throttle the incoming air (also aids efficiency). The fuel in a normal gas engine is ideally all vaporized and well-mixed with air before the spark occurs. It then combusts fast, as quick as the flame front crosses the cylinder, and during minimal piston motion. I don't get from the video how the SkyActiv-X is like a diesel, so I'll speculate. I think they first inject a fine spray, which vaporizes and premixes with the air, so that the spark can ignite it. The rest of the fuel is injected later so that it can burn around each droplet as the diffusion flame in a diesel. The premixed cloud igniting raises the cylinder pressure and temperature so that the bulk of the fuel then ignites. But, this would require direct-injection into the cylinder, and they don't depict such an injector in the video. Just found a CNET article which says it does have DI. Going to watch the Engineering Explained youtube about it since he is smart. I'm done with this explanation by English majors.

I had my doubts watching the video.. and I think you confirmed it.. looks exactly like a bunch of bs coming from people that either wanna pretend they explained it well or just plain straight had absoutely no clue how it works.. the most useless video I've ever seen

We can also use multi sparks in a cylinder either by using sparks plugs or any other methods .....it also increases the speed combustion

I am sorry but I missed it. Both Conventional Petrol engines and SkyActiv X uses spark plugs to ignite. So how is the mazda engine different? The shape of the piston that enables a uniform combustion?

I own a (USA) MAZDA CX 5 GT Reserver 2.5 L. turbo, AWD and love its quality and handling - and almost non-exist tant turbo lag. NOW to the Skyactive X add: 1.)->Hyundai's Variable Dwell camshaft and 2.)->the newTPS (Transient Plasma Systems) plasma plug for more instantaneous spark control AND color running. The TPS will have to wait a year or two to be market ready. Still, the gasoline engine may get another reprieve with these technologies.

Looks like it has a hybrid system with direct and port injection? Is this true? If so i'm gonna buy a Skyactiv X in the future.

With the lean burn, what sort of after treatment would you need? I imagine you'll get a lot of NOx. Will you have a TWC with a GPF and active SCR?
@stijn2644
@stijn2644 4 года назад
actually it runs so lean that the combustion temperature stays really low. also because there is so much air in the cylinder it will cool down the burned gasses. engineering explained did a fantastic job on explaining the engine on his channel.
@skaownz234

Lean doesn’t actually burn hotter, but slower, meaning less work can be extracted by the piston and therefore a bigger percentage of the energy gets deposited as heat into the piston and cylinder walls.

so all you did is more spark and compression like using a MSD?

Is it a GDI engine, or port injection.. so intake valves will be kept cleaner..??

How is this different than high compression superbike engines?
@Manuqtix.Manuqtix
@Manuqtix.Manuqtix 10 месяцев назад
So hang on. The supercharger is not there to add performance? It’s there to allow the combustion to happen?

I'm very late to the party here. What I've wanted know for years is:- What is the etymology of the word "Skyactiv" ?
@mazdauk
@mazdauk 5 месяцев назад
Hi John, thank you for contacting Mazda. The etymology of 'Skyactiv' was inspired by uncompromising performance and efficiency. We don’t believe you should sacrifice fuel economy to enjoy a thrilling driving performance. That’s why we found a way to achieve both, developing our revolutionary Skyactiv Technology.

@generalzod7959
@generalzod7959 4 года назад
There us no timetable. They're gonna test out some smaller engines first over in japan and Europe first and work out the kinks before bringing it the states. I'd guess a couple of years.

We need to improve infrastructure to support EVs. That in itself is quite difficult. It's becoming more and more difficult for car manufacturers to meet emissions standards. What's next, fart into the gas tank?
