WD12 Series Diesel Engine, Weichai European R & D center of the world's leading technology research and development of a new generation of diesel engines and the new design concept, refresh the number of performance indicators in the domestic heavy-duty diesel engines with more fuel-efficient, more powerful, more reliable, more secure, The main economic indicators have reached the world leading level.WD12 diesel engine is developed for heavy-duty vehicles market advanced power products Weichai Power, is currently the only mature maximum displacement diesel engine. 336 hp - 480 hp power coverage, comprehensive operation to reduce fuel consumption by 10-15% compared with existing similar engine with the power, power is increased by 30%, you can guarantee that the vehicle is efficient, high-speed operation, is the domestic heavy-duty vehicles ideal upgrade power.WD12 series diesel engine technology advantages:More fuel-efficient - the same load, fuel consumption is reduced by 15%, the use of cost savingsLarge displacement, high into the air; supporting dedicated P12 high pressure fuel pump, fuel injection atomization better; supporting for efficient turbocharger, intake efficiency; WD12 engine more complete combustion, lower fuel consumption.
More powerful - 12 liters displacement, torque increased by 30%, more powerfulWD12 engine displacement, low-speed torque increased by 30% (1000r/min); making the car accelerate better performance; maximum torque, the vehicle load capacity greater; wide range of high torque at 1200 - 1650 rpm range able to output high-torque, making the car able to efficient operation in a variety of operating conditions, and can greatly improve operational efficiency, to achieve the purpose of "Dora Run".
More reliable - a lower heat load, longer component life, reduce maintenance costsLarge displacement, lower the heat load of the same power - WD12 diesel engine displacement of 12 liters, compared with existing similar engine with the power up the lowest power, diesel engines machine's reliability has been greatly improved, crankshaft, connecting rods, bearings and other components last longer; delayed oil aging rate, extend the replacement cycle of oil, bring substantial direct benefits to the user.High-strength body - WD12 diesel engine body comprehensive structural and reliable experimental performance 20% higher than similar productsHigh pressure oil pump with the Franz gear - flange connection makes higher precision injection advance angle, avoid the advance angle changes lead to the emergence of the deterioration of the diesel engine performance and emission targets to reduce vibration, and comprehensively improve the reliability of the machine .Pump side - not connected with the fan, reducing component failure rate, easy maintenanceSafer - standard the Weichai unique WEVB technology, brake efficiency of 50%. After using WEVB engine braking system, vehicle brake efficiency can be increased by 50%, greatly increasing the security of the vehicle running.After with WEVB auxiliary braking system, the car on long downhill braking action role in the number and duration of action was significantly reduced, to reduce mechanical wear of the wheel brakes, but also to reduce the intensity of the work in the driver's braking process. Compared with other types of engine retarder, WEVB auxiliary braking system is low-cost, fewer parts and easy maintenance changes.The unique high-end configuration and structure - the high pressure fuel pump, starter motor, alternator, Germany BOSCH Company and Weichai signed a strategic cooperation agreement: to enforce exclusive supplier in the field of 126 mm bore diesel engine, Weichai Power.
