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.
