• High pressure common rail fuel system (HPCR), the fuel injection pressure is up to 1600bar, the throttle response is fast at different speeds, the power output is more efficient, the fuel economy is better, and the noise is lower
• Mature intelligent electronic control technology improves the overall performance of the engine, and the engine specifications can be customized according to the application requirements, with stronger self-diagnosis and self-protection capabilities
• The filter system is redesigned for oil products, with strong fuel adaptability, suitable for applications in various fields
• Strong environmental adaptability, good cold start performance
• The overall modular design, the total number of parts is small, the failure rate is low, the structure is compact, and the maintenance is easy
• High-strength new cylinder design, increased displacement, better reliability, low noise and longer service life
• Adopt wastegate type turbocharger, the boost is smoother at low speed, and the power output is more stable at high speed
• Rear gear chamber power output with significant noise reduction effect
• Three-stage fuel filtration ensures balanced particle dispersion levels, protecting major fuel system components and maximizing engine life
• The electronic control system can intelligently switch the working mode according to the environment and operating conditions, and has the functions of self-diagnosis, alarm and remote monitoring
• Mature intelligent electronic control technology improves the overall performance of the engine, and the engine specifications can be customized according to application requirements
