YC4AT Agricultural Series

Features for YC4AT Series Agricultural Diesel Engine

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

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.
