I would even like to see it with water injection every other cycle, as done with the 6 stroke normal petrol engine; it gets rid of external coolant and uses the left over heat of combustion to drive the vehicle. These engines are very smooth, very powerful, light and efficient. They also rev higer because of the smaller stoke per piston. I really dont know why car makers arent using them already, they are very good.

Interesting. I would have thought the following were a problem in cars/trucks: Rapid heating and cooling: It's going to alter (weaken?) the engine block. Might temper it in such a way it improves, not thsat much of an engineer. Steam: These things must puff out steam like billy-o. Or they would need condensers. Water: Obviously, if you have a condenser you can recycle, but I'd assume this would end up with warm water being injected. I think this would reduce the power gain, naturally it would reduce cooling. :/ Seems like sensible arrangement though, especially as the cost of fuel rises. Must be more complex & expensive to manufacture.

When I was a fully grown adult, capable of making a rational decision I bought a Trabi. Why? Because they rock! For getting around town they where ideal and they really annoyed the green lobby; which was nice.

This one is also a pretty good piece of engineering: Wankel_engine[^]

I think they are but the fact that you need to get the rebuilt after 50K-60K miles makes the idea of the Wankel a poor engine. Someone I work with just had his RX8 engine rebuilt to the tune of £2500 pounds.

No, not complicated at all really. They have no valve train, and are more thermally efficient. They have a blower to help scavenge, but most diesels have a turbo anyway. They are simpler than todays engines. The steped piston isnt different from the crank case scavenged tqo stoke which is simpler and widely used today.

Check out the 6 stroke engine, there are some vids on line, they are incredible. So sinple, so efficient. Of course you need a water tank as well as a fuel tank. The gasses are natural, but yes, they will steam a bit. The main thing is it gets rid of the radiator, hopses, water pump etc etc etc. A smaller, tidier engine even with the addition of the water pump and additional injectors. It will happen. You wait.

Nope. Yugos are ex Fiats, 127s and 128s to be precise.

But inefficient, not ecconomical and dont produce much torque.

Ahh! Happy days! I got my tracked vehicle licence driving a very large, very heavy tin box, powered by a Rolls Royce K60 multi-fuel. Mind you, if you used the wrong oil in the fuel type control, then the seal would perish, the plunger drop, and the engine go to full throttle. I once saw one of these tin boxes drive straight through the side of a German farm house... :omg:

It's very different! It uses a 4 stroke-like lubrication system (which means the lubricant isn't total loss with the emission problems that gives "normal" 2 strokes) and the ratio of the two piston's swept volumes can be adjusted to increase or decrease the "supercharger" effect.

:) Actually the hotel I am in in Germany got hit by a car. It bust one of the main wodden uprights and pushed it and the wall into reception. I dont thihnk it would be hard to go straight through if you had some welly behind it!
