摘要： The present invention relates to a continuously variable valve lift system for engines, which can prevent deterioration of fuel efficiency due to a friction loss by a return spring even in a low lift operation state by making a high lift swing angle be larger than a low lift swing angle, easily implement the CVVL by reducing a lost motion angle to an optimum condition, and securely generate an advancing effect in spite of reduction of the lost motion angle. Further, the continuously variable valve lift system is easy and convenient to adjust a clearance of an oscillating cam link, prevent the clearance of the oscillating cam link from being accumulated, and has a convenience of workability in adjusting the clearance in a narrow engine room.

摘要： An engine includes a pre-chamber jet igniter which injects at least one jet combustion flame into the combustion chamber from the outside of the combustion chamber in which the piston reciprocates to generate power so that the injected jet combustion flame is utilized as the source of ignition of the fuel injected into the space in the combustion chamber to drive the explosion stroke such that combustion of the combustion chamber can be maintained reliable by the use of jet combustion flames in the form of large flame kernels, fuel consumption can be remarkably improved and the generation of NOx can be remarkably reduced using rapid cold combustion which is caused by the continuously reliable combustion, and, in particular, it is possible to prevent liquefaction of the air-fuel mixture due to variations in the flow and pressure of the air-fuel mixture flowing in the combustion chamber.
