Detailed Information
Technology Advantages
Integral cylinder cover The entire engine is endowed with high rigidity, low vibration and noise.
Piston with inner cooling oil passage The cooling effect of the piston is improved, so is the reliability of the piston.
Integrated design of the whole engine With the parts in small quantity, the D series truck diesel engine is light in weight totally, reducing the fuel consumption effectively.
Swirl chamber type combustion chamber with dual extrusion The quality of the air and fuel mixture is improved to realize high combustion efficiency, low fuel consumption and emission.
Specialized efficient supercharger for trucks The fuel consumption is decreased effectively.
Imported Japanese high pressure fuel pipe made of double layered metal materials The fuel pipeline features excellent resistance to high pressure and corrosion, as well as high reliability.
Nippon Denso fuel system with high pressure common rail The maximum fuel injection pressure is 180MPa. The fuel gets good atomization effect and excellent adaptive capacity. This system enables the engine to show low emission, noise and fuel consumption but high reliability.
Intelligent temperature control technique The engine offers warming up at low temperature, protection and alarm at ultrahigh temperature. The engine friction pair gets the intelligent guarantee on its reliability and the extension of the lifespan.
Full flow oil filter attached with fine strainer Reduce the impurities in the oil and the abrasion of the piston ring.
Double operation mode and multiple operation mode technology Improve the compatibility of the power type with the vehicle and reduce the fuel consumption further.
Electronic control integration technology It realizes the integrated control on the engine and the performance of the vehicle, such as cruise control, GPS positioning, remote warranty, etc. Meeting the needs of users, the D series truck diesel engine is progressive, intelligent and convenient for use.
