Weichai has been separated from Sinotruk, 05 years Sinotruk built a factory in Jinan to produce engines, and now Sinotruk uses its own machines and Hangfa, Weichai and Shaanxi Automobile went together. Now there are only Euro 3's.

WD615, W
is water-cooled, d is diesel, 6
It represents 6 cylinders and 15 represents single-cylinder displacement.
The latest explanation: WD stands for Weichai Power, that is, Weidong, and 6 is 6
It represents 6 cylinders and 15 represents single-cylinder displacement.
Main technical parameters:
WD615 diesel engine in-line 6 cylinders, bore 126mm, stroke 130mm, single-cylinder displacement, engine displacement. There are naturally aspirated, supercharged, supercharged and intercooled models, the basic speed is 2200r min, the power range is 176kw-280kw, and the minimum fuel consumption rate is 194g, which has the advantages of small size, light weight, high power, low fuel consumption, advanced emission indicators, low noise, strong versatility, etc., and is an ideal power for heavy vehicles, various construction machinery, buses, power generation equipment, ships, etc.
WD615 is the abbreviation of WD615 diesel engine, WD615 diesel is accompanied by the country in order to make up for the lack of weight in China's truck market, from the Austrian Steyr company as a whole to introduce the Steyr heavy truck platform and come to China! At the beginning of its introduction, the WD615 engine was produced by two companies: Weifang Diesel Engine Factory (now Weichai Holding Group) and Hangzhou Engine Plant (now China National Heavy Duty Truck Group Hangzhou Engine). At that time, both companies were subsidiaries of China National Heavy Duty Truck Group (Sinotruk, that is, the merger of China National Heavy Duty Truck, Shaanxi Automobile, Hongyan and other companies before they were separated).
Development history: WD615 engine products have a high status in the hearts of Chinese heavy truck users. It can be said that without the introduction of the Steyr platform, there would be no Chinese heavy trucks today. From the beginning of the introduction of WD615 diesel engine, Weichai and Hangfa factories have continuously invested great manpower and material resources to digest, absorb, develop and upgrade this engine.
Emissions have ranged from zero emissions in Europe to China IV emissions that you can see today.
Supporting fields from the development of heavy truck engines to today: heavy trucks, buses, construction machinery, ship power, power generation equipment, agricultural machinery, stationary power and other fields. On the basis of WD615 Euro II emissions, Weichai Power has developed the WP10 series China III emission engines.
The main Bosch common rail system is promoted. China National Heavy Duty Truck developed the WD613 China III emission EGR series engine.
