Big bores made room for the big valves that could fill cylinders at high rpm, and so make more power. Short strokes reduced piston acceleration at any given speed, helping to make high rpm ...

As the piston moves downwards in the cylinder, the intake valve(s) open(s), and the vacuum created by the piston’s motion pulls the air/fuel mixture in. Or if the engine has direct injection, the ...

Unlike Honda’s oval pistons, which were positioned longitudinally ... through larger valves or by increasing the number of valves per cylinder. This could be particularly useful in mid-engine ...

The cylinder head helps to form the combustion ... Engines are made up of over 300 bolts and dozens of moving parts, like pistons and valve springs, that all work together to turn combustion ...

Using pneumatic cylinders from the LEGO Technic ... are no fuel-air explosions involved, these pistons are also double-acting thanks to a valve mechanism that switches the pressurized side of ...
