Inline 3 Cylinder Engine - Explained

The inline 3 cylinder engine is similar to an inline 6, but cut in half. I3's make a good choice for small, compact, and cost-effective engines producing good fuel economy. The primary and secondary forces are balanced (vertically), though unlike an I6 there is a rocking moment front to back on the engine, as there is a plane imbalance. These engine are becoming more popular with demand for greater fuel economy rising. They've also seen some use with modern sports/race cars, used in the Nissan ZEOD RC as well as the BMW i8.

1. I have three cylinder engine in my car, and works very smoothly. When idling it has almost no vibrations, in cabin you don't even know it's working or not. Real downside is the sound (which is horrible at any given moment) and it becomes very noisy under heavier load.
2. you mean justified. four cycles, four cylinders. it's just more practical.
3. There is a power stroke every 240 degrees not every 60 degrees.
4. I have an inline 3 cylinder Triumph motorcycle. 2.3 liter displacement. It is as smooth as any 4 cylinder motor I have owned, no matter the RPM. It revs very quickly and has tons of torque at low RPM with minimal vibration. Yeah, it can be lugged down to where things get uncomfortable, but just twist the wick, and it's gone.
5. In a 3 cylinder engine there is 120 degree difference between power strokes of 3 cylinders. But what is the case with 4 cylider engine. Can anyone please explain this.Also why is a 3 cylinder engine more noisy at lower rpms compared to a 4 cylinder engine?...
6. I have a Triumph Rocket III motorcycle (2,294 cc inline 3) and I appreciate the explanation on how this engine works. While it makes a lot of torque at low RPM, it vibrates badly under heavy throttle... and now I know why. Keep up the great videos!
7. hi sir you talk very fast !! i cant listen to you .
8. Did a Google search for 3 cyl engine and this video was the first result! Lol. The new Ford Fiesta ST got me thinking about it. Its weird that they went from a 1.6L 4 cyl turbo to a 1.5L 3 cyl turbo in the upcoming model.
9. I have a 1994 suzuki alto with a f6a 3 cylinder carburetorated engine, automatic transmission. can you or anyone please explain or help with setting the vacuum hoses in the right positions?
10. What I'm wondering is, is there any real advantage in a 3 cylinder over a 4 cylinder? Wouldn't a 4 cylinder crank be significantly better balanced and therefore more efficient?
11. i have a 3 in-line engine Diahatsu Coure. I know very well how badly it vibrates 😖
12. actually I didn't understand that how did you find out the firing order?
13. please tell me that what is mean to split crank.
14. sir please tell me that what you mean to split crank or can anyone can tell me that is that mean?
15. Interesting engines,i have a DKW which has a 3 cylinder two stroke with bearings in the Crankshaft and one single coil per cylinder(it means i have 3 engines in one) also the model its called 3=6 which it means this engine has the power from a 4 stroke 6 inline engine.I really love it
16. I have a dacia logan mcv that has a turbocharged 900cc 3 cylinder engine, and it's awesome
17. bro,why are you dividing the 240 by 2 ?
18. I had a 3-cylinder Chevy Sprint back in the '83/'84 time range.... Loved that little car - the savings in gas or fuel burn PAID for the car over what I got rid of.... Had to "row it along" with the 5-speed tranny and use higher RPM's..... It also had pronounced torque steer from a stop.... Thanks for the memories!!! Gordon
19. Good video, you know your stuff! I have a 3 cylinder daewoo matiz and it runs fairly rough at idle but ok at 2000rpm - now I know why
20. I'd Corsa car + 3-cylinder engine. Next I'd 1 + 4-cylinder. = 3-cylinder as fast as car +4-cylinders? I'd say yes, but I'm I correct?
