Toyota’s “Dynamic Force Engine” is designed with torque, power, and efficiency in mind. The whole idea of the engine centers on improving the speed of combustion. If combustion is faster, the engine makes more torque, and it does so more efficiently. So how did they do this?

Well there are numerous features of the engine which encourage quick combustion. It starts with a compression ratio of 13:1 for conventional engines, or 14:1 for their engine paired with hybrid vehicles. They’ve increased the stroke/bore ratio, increased the angle between the intake and exhaust valves, straightened the intake path, and incorporated laser clad valve seats. All this results in combustion that you can watch side-by-side occurring significantly faster versus the previous engine.

    Pretty slick. It's so impressive how far the modern engine has come!

  2. Now pair this with Mazda's sky-active tech and we will have to ultimate economy engine for all the MPGs!

  3. jbn675478 says:

    orrr I know, just throw an electric secondary motor in it and bam, problem solved. Great to see ICE engines get a little more efficient but really, the technology is on life support at this point.

  4. Ben Mcghie says:

    So much work going into efficiency… when you'd get far better fuel consumption by simply ceasing to fatten up the cars every year.

    Sacrifice a bit of safety, and you can have all the MPGs in the world. 90s civics, 80s golfs, 80s toyota pickups… any motorcycle ever… the examples are endless. Put the phone down, get some antilock brakes, and you simply don't need all this heavy crap on a car.

  5. Thank you Carl Sagan lol

  6. How does this compare to the skyactive X ?

  7. Ryan Nelson says:

    I want one!

  8. I'm Cmart says:

    They should put this on tv

  9. joe blow says:

    Looks like toyota discovered the hemi… I guess chrysler was way ahead of everyone else…

  10. MrIh8hondas says:

    So basically, they're applying the principle of intake swirl that's been used in diesels for decades to improve burn?

    Hey, I've been a long time subscriber (I'm a subie salesman and your videos are perfect) but I came here cause my Google Assistant recommended a jaloponik article. The video didn't load on their site because I clicked on the ad, but I wanted to watch it. Shout out to you man, you've been making quality videos forever and I love your channel.

  12. gerard321111 says:

    Great video. What thermal efficiency does the average car engine have?

  13. This would be an example of typical Youtube content if we were truly destined to inherit the stars.

  14. If we want the hybrid will we still be stuck with the horrendous CVT transmission? Is there a version for car enthusiasts with a manual box and a competitive level of performance?

  15. Hey, wanna make a video comparing this to the Mazda Skyactiv-X? I'd like it if you made a video comparing this engine with Mazda's Skyactiv-X.

  16. How did they get the video of the ignition? did they put a camera on a piston head?

  17. Gabe P says:

    so they are reducing the diameter of the cylinder and increasing the distance of the stroke? so of course this is going to make more compression on its own (not even considering the valve angle adjustment.)which means more power. wouldnt the combustion on a smaller engine be quicker than combustion on a bigger engine anyway simply because of the smaller surface area/volume?

  18. s13one80 says:

    Anyone else thought of a rasengan in the combustion chamber? No one? I'll see myself out.

  19. Awesome video and explanation. I love your channel. But as far as the tech goes, you can only polish a turd so much. Gas is gas. Electric cars are far more efficient… The only future gas has is in motor sports, but even then electric kicks it butt.

  20. Blu Subie says:

    You should honestly be a college professor. Not only do you explain in terms that are super easy to understand, you have such a strong drive to educate that most educators don't even have.

  21. Bruce Wilbur says:

    Easy to understand. Great learning tool. Thanks.

  22. User Name says:

    I've noticed a lot of engines are going back to under square designs.

  23. Goldmarble says:

    Hey, wondering if you could explain why uniflow 2 stroke engines are unpopular with car manufacturers? Either valved (Like Detroit 2 strokes) or Opposed Piston (Junkers jumo, Napier Deltic, Commer Knocker, etc)?

    Before people replying start talking about burning oil, and emissions; the engines I am talking about used a roots style blower, for scavenging, not crankcase compression. There is no oil being burned.

  24. sompka says:

    Its a high compression engine. With a shitload of electric accessories to reduce the perceived load. Didn't diesels hit 40% nearly a century ago? A higher ratio probably increases combustion speed as well due to increased reaction violence. valve angle changed? Who cares? literally every head made has different designs and valve angles.

  25. chunky soup says:

    The M20A-FKS in 2019 Corolla hatch will have that.

  26. soulhunter0 says:

    Just for a measuring stick comparison, what would be, nowadays, the average thermal efficiency of most cars?

  27. Does that mean higher revving engines

  28. I see more power across the rpm band, does that mean they will further reduce engine size in their production motors? It'd like to see some real world mpg ratings.

  29. Jakub K says:

    Which toyotas will have this technology?

  30. León Angel says:

    Hello Jason, you should talk about the Fiat/Lancia Triflux engine of the ECV.

  31. Nice. I liked my 2014 2.0 mazda 3. Got 43.6 mpg and drove like a racing gokart. But their motors get noisy over time

  32. S. S. says:

    Good video, looking forward to hearing more good things from Toyota

  33. mujjuman says:

    what is this sorcery?

  34. Two questions. What is thermal efficiency? And what is the gas mileage going to be?

  35. Matheus says:

    Hi Jason! Could you explain to us if replacing stock headlight bulbs (~55W) with more powerful ones likes 100W could damage your car's electrical system or other parts and why? Thank you in advance!

  36. TRLWNC1 says:

    An under square engine is more efficient. Imagine that. Diesels have known that for a long time… ;)

    How do you feel about combining technologies?

  37. TON O'CLAY says:

    Im just glad companies are finally fixing the combustion engine

  38. toyota's new layout with mazdas spark = save the gas engine

  39. Thanks again Jason, for this great video. Big shout out to you. Dutch regards.

  40. assuming this is a car engine. Isn't this a waste of the developers R and D budget. As we are all aware, EV`s seem to be the future, not gasoline.

  41. Still seems inferior to Mazda's Skyactive X since it ignites the fuel air mixture all at once. Not sure of it's thermal efficiency but you would think it would be higher given the higher CR and advanced ignition.

  42. Dejan Lazar says:

    that could actually be a good idea you know and the cars could live longer piezo injectors and piezo sparks could do the job here and a pretty good job

  43. Nick Amarit says:

    With such a long stroke length, what's the redline?

  44. David Teo says:

    @mazda Collab?

  45. I very much appreciate videos like this.

  46. Tom Dilbeck says:

    Congratulations Toyota on building a Mazda SkyactiV engine from 2011 (41% thermal efficiency, Skyactiv-X is coming in at about 56%). This is about as exciting as Toyota NASCAR; been done before, better, in better cars.
