Cummins DCEC QSL8.9 engine advantages
• Key components are developed, optimized and integrated by Cummins, and customized secondary development for domestic customers, adhering to the reliability of original products and taking into account the exclusiveness of domestic customers
• The integrated oil and water line 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 fast throttle response at different speeds, better power and fuel economy, and lower noise
• Adopt wastegate type turbocharger, the boost is smoother at low speed, and the power output is more stable at high speed
• Rear engine power take-off (REPTO) available for enhanced remote equipment control
• Good cold start, easy to start even in alpine regions; strong fuel adaptability, suitable for various applications around the world
• 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
