产品特色

qcv12 缸系列发动机是在原 12v 柴油机的基础上改进设计的一款用于发电机组的产品，在产品质量、可靠性、经济型、环保、振动噪声和外形上实现了重大升级。燃油系统、进、排气增压系统进行全部优化，功率范围覆盖 510-660kw。

qcv12series engine is a new type of engine designed by on the basis of the original 12vdiesel engine. the fuel system, intake and exhaust pressurization system are all optimized, and the power range covers 510-660kw.

产品特点

采用了高合金铸铁，整体式缸盖，采用 avl 切向气道的气缸盖，降低了涡流比， 提升了进气流量系数气流强度，增加气流压力，提升功率并有效降低排放。

采用双水泵、大流量机油泵，提高了柴油机高功率下高热负荷工作的冷却能力； 采用外置机油冷却器，提升了冷却润滑能力，满足不同环境温度的地区使用。

采用增压器中置排气管，优化密封结构，降低漏气概率提高增压器的工作效

率。

加大曲轴行程，增加排量。

采用高压力大功率燃油泵，满足更大的功率要求，同时配用高强度专用联轴

器，使结构更加稳定，提高供油可靠性。

high alloy cast iron, integral cylinder cover and avl tangential cylinder cover reduce the eddy ratio, increase the air intensity of the air intake flow coefficient, increase the air pressure, increase the power and effectively reduce the emission.

double pumps and large flow pumps are used to improve the cooling capacity of diesel engine under high power. external oil cooler is used to improve the cooling and lubricating ability and meet different environmental temperatures.

the central exhaust pipe of the supercharger is adopted to optimize the sealing structure, reduce the probability of air leakage and improve the efficiency of the

supercharger.

increase crankshaft stroke and increase displacement.

high pressure and high power fuel pump is adopted to meet the requirement of higher power. meanwhile, high strength special coupling is used to make the structure

more stable and improve oil supply reliability.
