Abstract

Method and devices for controlling the combustion of a four-stroke engine. For each cylinder, in addition to the main combustion chamber, a smaller secondary combustion chamber is provided. The secondary combustion chamber is completely separate and independently supplied with a compressed fuel-air mixture such that, when the mixture is ignited, the explosion that takes place through a transfer channel into the main combustion chamber, igniting the mixture contained therein. The main combustion chamber is not supplied with fuel at low speeds. Application is also contemplated for four-stroke engines with spark or other ignition and with rotary or valve timing.
