Patent technical requirements for low-speed diesel engine

YC6M diesel engine is a 50/60 loader special diesel engine developed by Yuchai Company on the basis of absorbing and digesting many modern diesel engine technologies from the United States, Japan and Germany, and strictly following the mechanical development plan of FEV Company in Germany for three years, with a displacement of 10L and a power coverage range of 220 ~ 390 PS. The most advanced casting, processing and assembly production line in China has invested more than 654.38 billion yuan, 80% of imported equipment is strictly controlled according to QS9000 quality system, and the quality is stable, with an annual production capacity of 70,000 units. After this series of diesel engines were put into the market, they were recognized by the majority of users. They are a new generation of large-scale construction machinery products, and they are the real embodiment of "Yuchai machine, ace power" in construction machinery.

● High reliability: high mechanical strength. Under normal use and maintenance, the engine overhaul cycle can exceed 12000h.

● Good dynamic performance: the torque reserve coefficient is as high as 25% or more, and the low-speed torque is large, which can ensure the strong starting ability and fast acceleration of the supporting mechanical vehicles and ensure the high working efficiency of the supporting construction machinery.

● Low noise: adopt the indoor structure of rear gear and the patented technology of point-and-line meshing gear to reduce noise. Test result of noise sound power level ≤ 1 13dB(A).

● Low emission: Diesel engines for construction machinery (non-motor vehicles) were tested according to Beijing local standard (DB11185-2003), and reached the first-stage value.

● Low fuel consumption: the minimum fuel consumption at full load is ≤ 193g/kW.h, and the percentage of oil consumption is ≤0. 10%.

● Strong environmental adaptability: the working performance of 5000m plateau is not affected, and it can work normally in desert environment.
