Abstract

The invention relates to a timing chain transmission system and an engine comprising the system. The timing chain transmission system adopts two-stage transmission including primary chain transmission and secondary chain transmission; power is transmitted between the primary chain transmission and the secondary chain transmission through an idle wheel with two chain wheels. According to the timing chain transmission system and the engine, the assembling cost is reduced, and the service life is prolonged; the severe requirements on all the aspects, such as emission, stability and noise, of the engine can be met.

Description

technical field [0001] The invention relates to the technical field of engine transmission systems; more specifically, the invention relates to an engine timing chain transmission system. [0002] Further, the present invention also relates to an engine comprising the aforementioned timing chain drive system. Background technique [0003] The traditional engine timing drive has three modes: chain drive, toothed belt drive and gear drive. Among them, the chain drive has been widely used in the engine in recent years because of its small footprint, good reliability, maintenance-free and low overall cost. product. [0004] The timing chain drive system of a general engine is usually directly driven by a chain between the crankshaft and the camshaft. In some engines (especially diesel engines), a high-pressure fuel pump (oil pump) is often required for fuel supply, and the drive of the fuel pump also needs to be completed by a chain system; in diesel engines that require a bal...
