摘要

Method and device to improve the performance of an engine ignition at low and high loads and understanding in the boot. Consists in modifying the profile and depth of distribution channel, so that a Valve in the Exhaust Stroke that causes a certain absorption of the Burned gases.Similarly, in the intake Stroke, the Intake Valve must be closed slightly before the PMI, the race was shortened effectively understanding in practice. All of this is to increase the temperature at the end of the career of understanding at the start and at low loads, and limit the final pressure at full load. There are variants of the procedure.Application in diesel engines, turbocharged or not.
