Using the research and development supporting platform by home and abroad, Weichai focuses on the operating conditions of rollers and graders to develop from reliability, economy, power and other aspects, successfully launched the second generation engines for rollers and graders.
Engines for rollers WP4G, WP6G, WD10 and WD12 Series
Engines for graders: WP6G and WP7G series
Second-generation fuel-efficient technology for rollers
1、Reliability technology
(1)Highly reliable cooling and lubricating system
1)High water inlet position structure
Sufficiently cool the piston, cylinder liner and other high temperature components
2)Oil cooler and filter integration design
Reduce external pipes with a nice overview
3)Tandem oil cooling structure
Coolant will cool the oil first before going into the large circulation. Improve the oil cooling capacity and engine lubricating capability
(2)Highly reliable gear train transmission system
1)Automatic tensioning system for the front gear train. Easy maintenance, smooth transmission and high reliability
2)Increase the number of ribbed belts so that the transmission power is high and belt slippage is prevented.
(3)Highly reliable PTO structure
