Main Features :

Tractor power profile
Tractors series diesel engine was researched and developed  by QuanChai company, which  integrate domestic and foreign advanced engine design concept,adopt Pro-E, UG and other advanced 3D design software,use the advanced CAE analysis technology,  optimize the  structure to improve the  stiffness of parts , fully guarantee the high reliability, strong power and good economy.
Products include A, B, C, D four product platform, a total of 22 basic models can be choosed , is the  reliable power for  25 to 75hp tractor.
• 1, use the direct injection combustion chamber, easy start, low oil consumption, good economy.
•2, long stroke,large torque backup, strong power.
•3,cast iron oil sump, strong rigidity, convenient maintenance; integrate  flywheelcover to ensure reliable connection with tractor.
•4, through strengthening design of gear system , hydraulic PTO power output is more stable.
•5, speed rate is low, with the advantages of speed stability, small vibration, low noise 
•6, the key parts are same as of parts for vehicle diesel engine,better exchange and universality and durable.
•7, the structure is compact, light weight, convenient installation and arrangement..
•8, The emissions is State II of non road series  and some model's emission can meet Euro III
 
Tractor series diesel engine has premium quality ,and the use of direct injection combustion chamber , easy to start , low fuel consumption, economical ,compact structure , light weight ,easy to start and install, it has the advantages of large torque , small vibration ,low noise , low transfer rate and etc., the key components is optimized for high-speed automotive diesel engine parts and components ,so that the diesel engine has good market interchangeablility and versatility.
