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.
