●Cummins has developed and optimized the five key systems to ensure reliability.
●High pressure common rail (HPCR) system with injection pressure up to 1600 bar, fast throttle response at different engine speeds, efficient power output, improved fuel economy, and low noise.
●The mature intelligent electronic control technology improves the overall performance of the engine. The engine specifications can be customized according to application requirements. The self-diagnosis and self-protection functions are improved.
●The redesigned filtration system for oil with high fuel adaptability can be used in various applications.
●High environmental adaptability and good cold start performance.
●The overall modular design enables less parts, low failure rate, compact structure and easy maintenance.
●The new high-strength cylinder design offers higher displacement, higher reliability, lower noise and longer service life.
●The exhaust gas bypass turbocharger enables smooth boost at low engine speed and consistent power output at high engine speed.
●The rear-end power takeoff significantly reduces noise.
●The three-stage filter ensures balanced particle dispersion, protects main components of the fuel system and maximizes engine life.
●The electronic control system intelligently switches to operation modes according to the environment and operating conditions. It has self-diagnosis, alarm and remote monitoring functions.
●The mature intelligent electronic control technology improves the overall performance of the engine.The engine specifications can be customized according to application requirements.
