Brief Introduction to YC4F Series Engine
YC4F series diesel engine is a light-duty one of low-emission, energy efficient and environmental protection type with a displacement of 2.66L/2.98L and power coverage of 90 ¨C 120 horse powers to be applicable for light-duty truck market. The engine is designed in cooperation with FEV, Germany, and adopts multiple achievements of scientific research for modern diesel engines, in particular, engines up to Euro-III standard adopt also several achievements of scientific research for modern diesel engines such as German BOSCH electronic control high pressure common rail or American DELPHI electronic control high pressure common rail technique, low vortex combustion chamber etc., and so it has reached the international advanced level in dynamic & economic indexes and now is in the lead of products of the same category at home.
Stronger power
Max. power 120PS, being in the lead at home in several indexes, such as average effective pressure, performance & torque per liter etc., powerful grade-ability and better acceleration characteristic.
Lower fuel & oil consumption
Lower fuel & oil consumption, wider range of economic fuel & oil consumption zone for combined characteristic, min. fuel consumption at full load ¡Ü203g/kW.h£»oil-fuel ratio in the bench test is lower than 0.2% which is at the lead of small-sized engines.
Comfort
Smaller vibration, lower noise
Reliability
The machine is developed by using the mechanical development program of FEV company, Germany, and featured by better reliability and longer service life. Under normal operation & maintenance conditions its mileage before the first capital overhaul may be more than 500000 kilometers.
Environmental protection
Up to Euro-II or Euro-III standard of emission
Easier maintenance
Wet cylinder liner structure, one cylinder head for four cylinders, better approachability, easier maintenance.
Better applicability
Wider range of power from 66kW (90PS) to 88kW£¨120PS£©, so it can be used for medium- or high-grade light-duty trucks.
