Advantages of DCEC QSL8.9-C340-III Industrial Engine

  • The integrated oil and water pipeline replaces the traditional hose, eliminating the hidden danger of leakage; the enhanced cooling and lubrication function effectively prolongs the service life of the engine.

  • Adopt high pressure common rail fuel system (HPCR) to ensure rapid throttle response at different speeds, better power and fuel economy, and lower noise.

  • Adopting waste gas bypass turbocharger, the supercharging is smoother at low speed, and the power output is more stable at high speed.

  • The engine back-end power output device (REPTO) can be used to enhance the control ability of remote equipment.

  • Good cold start performance, easy to start even in high-cold areas; strong fuel adaptability, suitable for various applications around the world.

  • 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.
