PROCEDE DE BALAYAGE DES GAZ BRULES RESIDUELS AVEC UNE DOUBLE LEVEE DE SOUPAPE D'ADMISSION D'UN MOTEUR A COMBUSTION INTERNE SURALIMENTE A INJECTION DIRECTE, NOTAMMENT DE TYPE DIESEL |
摘要 |
<p>The method involves carrying out a sequence of opening/closing of an exhaust valve (18) during an exhaust phase of a direct injection internal combustion engine when the engine is operated at a reduced speed and a heavy load. A sequence of opening/closing of an intake valve (28) is carried out during the sequence of opening/closing of the exhaust valve when the engine is operated at the reduced speed and the heavy load to scavenge residual burned gases. The sequence of opening/closing of the intake valve is started when an intake pressure is higher than an exhaust pressure.</p> |
