Features for YC4BT Series Agricultural Diesel Engine
YC4BT series diesel engines are the newly-developed high-performance power of agricultural
machinery with power coverage of 70 ¨C 100 hp at the speed of 2000 ¨C 2400r/m and
are applicable for tractors with a power of 70 ¨C 100 hp.
Main parts and components are designed by means of finite element analysis and the
engine is 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, and 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.
YC4B100T series engines are featured by higher reliability and lower fuel &
oil consumption and the emission is up to Euro-¢ò standard.
The oil sump of engine matching for tractor adopts the iron cast structure, and
featured by stronger rigidity and less deformation, can meet the requirement of
the frameless tractor.
