Utility can also be contemplated for 4-stroke engines with spark or other ignition and with rotary or valve timing. Variable move lowering valve and gradual management valve distribution system for a compressed air injection engine operating on mono or multi power andother engines or compressors.
Throughout low-power operation, e.g. in city traffic, the gasoline injector (6) is no longer controlled throughout filling of the combustion chamber, whereby the combustion chamber is filled with high-temperature pure compressed air at each cycle.
