Dear Experts,

The car moves basically because of the energy from the explosion that happens in the cylinder which pushes the piston whose reciprocal motion turns the wheels.

Does the explosion caused by the ignition of gas and air mixture lead to the exhaust gas dirtying the inside of the cylinder? With so many explosions occurring in short duration of time, does the cylinder get dirtier and dirtier with each explosion?

I think there is lubricant like some kind of oil inside the cylinder but if there is carbon in the cylinder, won't the oil also be contaminated?

regards

That is one of the reasons for oil changes. Ideally, there is complete combustion in the cylinder but that is not always possible (eg. during rapid acceleration where the system cannot cram enough oxygen into the cylinder to allow all the fuel to combust).

Hi Andrew,

Thanks so much for the explanation. Appreciate it very much :)

Have a nice day.

sincerely,
