Landking - High-tech brand of Weichai Power, the representative of worlds advanced power technology and clean and green power concept.
Landking China III engine is collaboratively developed by Weichai Power, Austria AVL, and international component suppliers with the full integration of todays cutting-edge technologies of internal combustion engine, and it is a brand new product. It is the most mature and most reliable China III engine and has reached the limits of China IV and China V emissions regulations.
Landking China III N series engine has the rated speed down to 1,900 rpm, and it has achieved the major technological breakthrough and reached the international leading level in the fuel-efficiency, power, reliability, comfort, etc. Landking China III series engines include WP12N and WP12N products with the power covering 240-480 hp.

Four breakthroughs of Landking China III N series (1900 rpm) engine:
Fuel-efficiency breakthrough
Landking China III N series engine of Weichai Power
（1）Rotation speed is reduced to 1,900 rpm - area of low fuel consumption is expanded;
（2）1900 rpm powertrain system is configured - transmission is more efficient to make the engine work in a more fuel-efficient area
（3）Personalized market and products – further reducing the fuel consumption of vehicle.Above three factors further reduce the fuel consumption of Landking China III N series engine.
Power breakthrough
Reliability breakthrough
Rotation speed of engine falling from traditionally 2,200r/min to 1,900r/min reduces the linear speed of piston and running speed of crankshaft linkage, gear system and belt system and improved the engine reliability with the overhaul period exceeding 1.2 million km.High pressure fuel pump flange connection structure, improve product reliability
Comfort breakthrough
Lower noise, smaller vibration and less shifting, the application of WEVB exhaust valve braking system.
Landking China III WP12N series engine
WP12 series engine, with the power 270-460ps and rated speed of 1,900 rpm.
WP12N series engine is a brand new product collaboratively developed by Weichai Power and Austria AVL, as well as the international components suppliers worldwide, with the full integration of the world’s cutting-edge technologies of internal combustion engine.
Large-displacement diesel engine in line with China III, China V and China V emission regulations.
Landking China III WP12N series engine has been through more than 80,000h bench test, road test of 80 vehicles and the road test up to 3 years and 5 million km and has passed the limit tests in the plateau and hot & cold areas; the engine technologies are advanced, with the excellent performance and high reliability.
WP10N series engine, with the power of 240-336ps and rated speed of 1900 rpm.
Landking China III WP10N series (1,900 rpm) diesel engine is a large displacement China III product developed by Weichai Power based on WD615 engine and with the electronically controlled high-pressure common rail system of BOSCH, and it meets the China III and China IV regulations. The structure and connecting dimensions are basic identical with WD615 China II series engine with the good inheritance;
Advantages such as high reliability, large torque reserve, etc.;
Low maintenance costs and most of components in common use with China II diesel engine.
Landking China III WP4/WP6 engine
Landking China III WP4/WP6 engine, with the power range of 150-240 ps and the rotation speed of 2,300 rpm, applies to the medium- and heavy-duty vehicles, buses and various special vehicles.
WP4 and WP6 series engines are based on 226B China II product, with the combustion system and fuel supply system newly designed by the most advanced high-pressure common rail electronic control system of BOSCH;
In highly common use with the components of China II diesel engine, and domestic leading level in the similar products for fuel-efficiency, reliability, emissions, noise, etc.;
Low maintenance costs, and 85% of components in common use with China II diesel engine;
Low use costs and more superior fuel economy.
