I think you are missing the point. We all know that modern engines work on the lean-burn system. In this way the perforated inlet port matches the perforated exhaust port and practically no fuel is required. Because the compression stroke is going to expell power draining excessive compressed gasses through both the inlet and the exhaust the system is in perfect balance. In fact no catalytic converter is required because the fuel air mixture is so lean that only slightly smelly air exits the exhaust port. Also it can be noted that the engine is extremely quiet so a completely open, straight through exhaust pipe can be used. All one hears as the car progresses down the road, preferably down in the literal sense, is a quiet chuffing. In fact the owners of these remarkable pieces of engineering are quite chuffed.

Personally I think that this means the end of the expensive and environmentally unfriendly electric cars.

Peter, thank you for explaining the technical details.
People without engeneering background will miss out some of the fine details but I am sure they'll get a general understanding...

I had to look at the post date thinking it was the 1st April.

I think it was!!!

When used solely on the inlet valves you will have, effectively, an Atkinson cycle engine. A pre-charged inlet tract with different inlet and exhaust volumes just like the Priuses that litter the roads.
So who's laughing now?

A very interesting topic and a new one on me.

I'm still laughing. Perforated inlet valves will not create an Atkinson cycle - will they?

Her name is Gemma Atkinson, and this is her cycle:

Now I know nothing about cycling but that wheel looks larger than average...is it legal?

Wheel?
Where's that then?
