Diesel engine
专利汇可以提供Diesel engine专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve initial running characteristic and to exclude knocking phenomenon by providing a control device for valve lifting whereby said control device can decrease lifting amount of a suction or exhaust valve at the initial running time or light load time of the engine to lower than compression ratio.
CONSTITUTION: A suction or exhaust valve 1 is opened against the elastic force of valve spring 7 by the lifting power from a cam 2 rotating synchronously with the engine revolution through an oil tappet 3, push-rod 4, wobbling cam 5 and rocker arm 6 as a valve lift controller. The arm length of oil tappet 3 is adjusted with response to the oil pressure from an oil pressure regulator 30 which serves as a detector for checking engine running state, so that the lifting amount of valve 1 can be made less in the initial running time or light loaded time of the engine. In such a way, unpreferably state in initial running is improved by less compression ratio and increased cranking r.p.m. and further knocking is excluded by lowered step-up degree of expansion pressure.
