1、Brief Introduction
YC4BT series diesel engines are the newly-developed high-performance power with power coverage of 70 – 100 hp at the speed of 2000 – 2400r/m and are applicable for the rice & wheat harvesters with a feed rate of 2.5 – 4kg/s and the self-propelled 3-row maize harvester.

3、Features
● 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 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-Ⅱ standard.
● The engine is decreased in the weight by adopting the oil sump made of the cold-pressed steel plate.
