Abstract
A cyclic internal combustion engine having at least one working piston and cylinder arrangement which includes separate compression, combustion, and expansion chambers that perform respective compression combustion and expansion cycles. The compression cycle is advanced up to 180° in relation to the expansion cycle, so as to extend the combustion cycle during the exhaust stroke to reduce the formation in the combustion cycle of polluting gases.
