The internal combustion engine

Click For Summary
SUMMARY

The discussion centers on calculating the number of cylinders in a four-stroke internal combustion engine based on the relationship between crankshaft rotations and piston ticks. In a four-stroke engine, there is one ignition event for every two crankshaft rotations. Given that the crankshaft spins 100 times resulting in 300 piston ticks, the engine must have six cylinders, as each cylinder contributes to 50 ticks (100 crankshaft rotations divided by 2). This conclusion is derived from the fundamental operation of four-stroke engines.

Hi Ugnius! :oldsmile:

A four-stroke engine has 1 ignition in every 2 turns of the crankshaft (intake - compress - ignition - expand - exhaust).
It's the ignition that gives the tick.
So if we'd have 1 piston, we'd have 50 ticks, but instead we have 300 ticks...
