Truck Diesel Engine

Landking— — Power brand of high technology of Weichai Power, is a representative of highest power technology in the world and of theory of cleanness and environment protection.
Landking (Euro III) series Diesel Engines, researched and developed independently by Weichai and AVL and co-designed with international parts supplier, is a flagship product designed with the frontline science and technology of internal combustion engine, is the most mature and reliable Euro III engine which is capable of Euro IV, V emission standard.
Landking Euro (III) N series Diesel Engines bring the rated speed down to 1900rpm, which leads to a great technical breakthrough reaching international leading level in the economy, power, reliability, comfort etc...Landking (Euro III) N series engines now include WP10N, WP12N etc., which cover a power range from 240 to 480 PS.
The four break through of Landking Euro III N series engine
The economical break through
Weichai Landking Euro III series engine
(1) Speed down to 1900 rpm to achieve a wider area of low fuel consumption;
(2) The 1900rpm power assembly match— Higher drive ratio, larger area of low fuel consumption;
(3) Individualized market and product— Makes the fuel consumption the vehicle even lower;
The three reasons above make the fuel consumption of Landking Euro III N series engine even lower than the Euro II series.
Power breakthrough
Reliability breakthrough
The low engine speed brings down the linear speed of piston, motive speed of crankshaft-connecting rod system, gear system and belt system which lead to huge rise of engine reliability. The period of repairing reaches 1.2 million km.
The flange connection structure for high pressure fuel pump structure improve the product reliability.
Comfort breakthrough
Low noises, Low vibration, Less gear shifting, Application of WEVB system.
WP12N series Diesel Engine
WP12N series Diesel Engine, with a power range from 270 to 480PS, rated speed at 1900rpm.
The Landking Euro III WP12N series are co-designed by Weichai European R&D Center and AVL BOSCH and other world-outstanding part suppliers with synchronized development. It is the brand new product which is designed with the frontline science and technology of internal combustion engine.
It is a large-displacement vehicle diesel engine that meets the Euro III, IV, V standard
The Landking Euro III WP12N series passed through more than 80, 000 hour bench tests, road tests of 80 vehicles, 5000000 kilometer road surface experiments over three years and plateau, high temperature, cold area tests. The advanced technology, outstanding performance and fine reliability is achieved.
WP10N series Diesel Engine

WP10N series Diesel Engine, with a power range from 240 to 336PS, rated speed at 1900rpm.
The Landking Euro III WP10N series (1900rpm) are designed by Weichai based on the foundation of WD615 series, using the BOSCH electrically-controlled high pressure common rail system. The contour structure and connection size are basically the same with WD615 Euro II Series which leads to a fine succession.
WP4/WP6 Series Diesel Engine

WP4/WP6 Series Diesel Engine, with a power range from 150 to 240PS, mainly used in medium-heavy vehicles, bus and various special vehicles.

The Landking China III WP4/WP6 series are redesigned based on the foundation of 226B China II series, The combustion system and intake and exhaust system are full-newly redesigned using the BOSCH electrically-controlled high pressure common rail system.
