The five key engine systems are developed and optimized for Cummins to ensure engine reliability.
High pressure common rail fuel system (HPCR), fuel injection pressure up to 1600bar, rapid throttle response at different speeds, more efficient power output, better fuel economy, and lower noise.
Mature intelligent electronic control technology improves the overall performance of the engine. The engine specifications can be tailored according to application requirements, and the self-diagnosis and self-protection capabilities are stronger.
The three-stage fuel filter ensures a balanced level of particle dispersion, protects the main components of the fuel system, and maximizes the life of the engine.
Adopting exhaust gas bypass turbocharger, the supercharging is smoother at low speed, and the power output is more stable at high speed.
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.
