But is it a ‘HEMI’?.........................
My hemi works just fine for me. 😂👍
I don’t buy the line about “lower friction”. The story repeats that it is but gives no reason for it. If anything, the friction would be worse. In order to have the same power, the oval piston engine would have the same displacement as the circular piston engine. This means that the area of the oval top has to be the same as the area of the circular top. This means that the ring contact area would be higher. It is this ring contact area that makes most of the engine’s friction. That means higher friction, not lower.
In addition, the long side of the oval would be more flexible than the side of a circular piston. This means that the overall contact pressure of the oval pistons would have to be higher to keep the same oil consumption, making the friction go up even more.
