Brief Introduction to YC6A Series Engine
YC6A series diesel engine is a new type turbocharged & intercooled diesel engine co-developed by YUCHAI and FEV company, Germany, who have simultaneously developed also the rear power take-off type engine, and so PTO driven by the gear at the power output end can meet the special requirement of the grouting machine. Compared with products of the same category, YC6A is featured by higher economy, better emission stability and characteristics of operation at lower speeds and starting at lower temperatures.
¡ñ Higher reliability
> Key parts are designed in an overall optimized way by using the finite element analysis technique and are capable of meeting the requirement of cylinder pressure up to 150 bar;
> Cylinder head with low vortex & low resistance airflow passages ensuring stable performance;
> Reinforced & optimized skirt of the cylinder block, ensuring smaller deformation & higher stability of emission;
> Wet type cylinder liner with higher body & supported from the bottom ensuring higher reliability & better maintainability;
> Adopting the technique of piston forced cooling;
> Adopting the technique of cylinder block water jacket with higher top ring;
> Adopting the pressure balancing technique of fuel-gas chamber of the crankcase;
> Built-in oil cooler ensuring higher cooling efficiency;
> Adopting the fuel injection system with BOSCH high pressure common rail or EUP;
> Adopting BOSCH P7100 fuel injection pump & P-type injector, which are capable of meeting the requirement of cylinder pressure up to 1200 bar;
> Adopting Holset (Wuxi) new HX40W turbocharger with the air relief valve featured by better dynamic characteristic.
¡ñ Stronger power
Max. rated power 280 horse powers
¡ñ Bigger torque
Max. torque 1100 N.m
¡ñ Lower emission
> Up to Euro-II and Euro-III standard and passed certification of both German TUV and China State General Administration of Environmental Protection for Euro-II & Euro-III standards for emission.
¡ñ Lower fuel & oil consumption
> Wider range of fuel consumption for outer characteristic and Min. fuel consumption at full load is equal to or less than 196g/kW.h
¡ñ Lower Noise
The average noise level at a distance of 1M is equal to or less than 97dB (A).
¡ñ Better characteristic at low temperatures
It is easily started without the cold starting device at a temperature of -18¡æ.
