Product Advantages

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.
