QCV12 缸系列發動機是在原 12V 柴油機的基礎上改進設計的一款用于發電機組的產品，在產品質量、可靠性、經濟型、環保、振動噪聲和外形上實現了重大升級。燃油系統、進、排氣增壓系統進行全部優化，功率范圍覆蓋 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.

產品特點

采用了高合金鑄鐵，整體式缸蓋，采用 AVL 切向氣道的氣缸蓋，降低了渦流比， 提升了進氣流量系數氣流強度，增加氣流壓力，提升功率并有效降低排放。

采用雙水泵、大流量機油泵，提高了柴油機高功率下高熱負荷工作的冷卻能力； 采用外置機油冷卻器，提升了冷卻潤滑能力，滿足不同環境溫度的地區使用。

采用增壓器中置排氣管，優化密封結構，降低漏氣概率提高增壓器的工作效

率。

加大曲軸行程，增加排量。

采用高壓力大功率燃油泵，滿足更大的功率要求，同時配用高強度專用聯軸

器，使結構更加穩定，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.
