Dongfanghong LRCl05 series diesel engine


Dongfanghong LRCl05 series diesel engine is based on LRl05 series diesel engine research and development of the larger displacement diesel engine. By optimizing the design of the crank connecting rod and other mechanisms, the combustion efficiency is higher, the power output is stronger, the fuel consumption index is lower, the power at the same speed is increased by more than 10%, and the maximum torque value is increased by more than 15%. It can further meet the higher requirements for dynamics of the construction machinery, agricultural machinery, trucks and other industries.

Dongfanghong LRCl05 series diesel engine has the same shape and connection size as the LRl05 series diesel engine, providing convenience for the upgrading of the host and improving the design requirements for power. At the same time, it adopts first-class processing and manufacturing and testing equipment in the industry, and adopts a large number of new technologies and processes to ensure that the Dongfanghong LRC series diesel engine not only has high performance, but also has excellent reliability and economical use.

Compared with the 108mm bore diesel engine of the Dongfanghong LRCl05 series diesel engine in the same industry in the same industry with the 105mm cylinder expansion, the LRCl05 series diesel engine has a larger displacement, higher power, low speed and high torque overload capacity, More reliable performance and other advantages. All technical parameters are in the leading level of similar models in the same industry in China.
