The present disclosure relates to piston engine systems which are no longer restricted by their compression ratios. Rather, a mixture of fuel and pre-compressed air is used to complete the combustion. The pressure of the compressed air is independently controlled. As a result, the clearance volume can be reduced to less than 1/50 or to zero, and the piston engine systems can be used with different types of fuels, for example, gasoline, diesel, ethanol, or vegetable oils.
