ABSTRACT:
The invention relates to piston-type internal combustion engines.
A four-stroke engine in which, on reduced load, a part of the cylinders is used as combustion cylinders, the other part forming an additional expansion enclosure for the gases issuing from the combustion cylinders before their expulsion into the atmosphere. The engine operates on full load according to the conventional cycle.
Application to the improvement of the output for motor vehicle engines when they operate on medium or low load.
