1﹜Brief Introduction
YC4AT series diesel engines are the newly-developed high-performance power with power coverage of 80 每 100 hp at the speed of 2000 每 2400r/m and are applicable for tractors with a power of 80 每 100 hp.

3﹜ Features
♂ Main parts and components are designed by means of finite element analysis and characterized by compact construction and reasonable stressing.
♂ Adopting the particular analog computing technique of FEV, Germany, ensures lower fuel & oil consumption and noise, stronger power, longer service life and higher reliability.
♂ Adopting the domestic technically mature A type fuel injection pump and the whole-travel type governor provides lower governor response rate and stable rotation speed of the engine, are specially applicable to the tractor.
♂ Adopting the built-in cooler ensures better cooling results to meet requirements of the agricultural machinery for continuous & full load operation.
♂ The oil sump of engine matching for tractor adopts the iron cast structure, can meet the requirement of frameless tractor.
