Weichai Power is the general application engine manufacturer with world’s advanced level, and is also the largest domestic power supplier for construction machinery.
After successfully developing and becoming the mainstream special power for the scraper machinery, road construction machinery, lifting machinery and concrete machinery, Weichai focused on the current situation of the domestic forklift market, researched the forklift working conditions deeply, and then developed a whole series of special power for forklifts. The quality, performance and cost are fully in line with the future trend of the forklift, and became the best choice for power of forklifts.
1.Adopting the well-known brand technology from Duetz, and is specially designed for mature industrial engines.
（1）High gantry design, flexural with anti-deformation ability, small vibration and low noise.
（2）Emissions: non-road China II
（3）Bore: 105mm
（4）Stroke: 130mm
（5）Displacement: 4.5L, 6.75L
（6）Power range: 80 ~ 175Ps
2.Features of forklift application engines
（1）Technical features of engines for forklift (WP2.5, WP2.7, WP3.9 and WP4.6)
1)High efficient and energy-saving
Adopting the P-type fuel injectors, and has features of high power, large torque and small smoke opacity. Compare to the similar engines in the market, the fuel economy of optimized combustion system was greatly improved.
2) Reliable and stable
All the engines adopt strengthened engine block and cylinder head assembly, which makes them more stable and reliable.
3)Easy maintenance
As mature products in the market, the maintenance technology is also mature and the spare parts supply is adequate. Weichai service network will provide worriless and convenient service all the way.
4)Excellent customer feedback
Feedbacks from the forklift manufacturers show that the forklift has the features of short lifting time, strong climbing ability and fast load acceleration.
（2）VM forklift engine outline
Product Positioning:
Domestic high-end trucks and exported products, have highly recognized by European brands. They can also meet Euro III emission requirements, and the cost performance was better than imported engines.
（3）Technical features for D series engine from VM
Technical features:
1)Exclusive license for the D series domestic production from Italy VM Company.
2)Tunnel-type cylinder structure greatly enhances the stiffness, so that the engine noise and vibration dropped significantly and the engine life increases substantially.
3)Using aluminum cylinder head and “one head for each cylinder” structure, the engine heat exchange becomes better and the weight becomes lighter.
4)The air inlet and exhaust ports are on the same side, so that the turbocharger layout is easier and the engine structure is more compact.
5)Using the balance shaft structure (optional), air distribution system with hydraulic tappet and gear chamber cover made of composite materials, engine vibration and noise are significantly reduced.
6)Using the expansion rod and optimized engine bearing clearance, high operation reliability of the engine is ensured.
7)The unique dispensing pump installation and maintenance structure leads to easy maintenance.
8)The independent PTO output structure is able to meet the all kinds of construction machinery and equipment application.
