English.chinabuses.com: At 9:58 on September 18, 2009, the fire ceremony of CA6DLD-30E4 two poles pressurization diesel engine held successfully in Xichai.

CA6DLD-30E4 diesel engine is the first two poles pressurization diesel engine by Xichai develop individually, the displacement of 6.6L, rated speed 2300 switch, rated power of 220 kilowatts, maximum torque of 1100 Nm, adopt cool EGR as the main technology of emission control, pressure system use two poles pressurization, emission come to state Ⅳ standard.

CA6DLD-30E4 diesel engine using two pressurization technology, with four obvious advantages, first, high power density, obvious lightweight feature; second is low-emission, low fuel consumption, lower fuel consumption lower than equivalent diesel engine 2 ~ 3%, to reduce carbon dioxide emissions and more green; third is to accelerate the fast response, due to the fresh air entered the cylinder through the two booster to accelerate the response to a substantial increase in performance; fourth is low-cost, the use of two pressurization technology, significantly reduce engine smoke.
