Cummins QSB6.7 Engine advantage
1.The five key engine systems are developed and optimized for Cummins to ensure engine reliability. 2.High pressure common rail fuel system (HPCR), injection pressure up to 1600bar, rapid throttle response at different speeds, more efficient power output, better fuel economy, and lower noise. 3.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. 4.The filter system is redesigned for the oil product, which has strong fuel adaptability and is suitable for applications in various fields. 5.Strong environmental adaptability, good cold start performance. 6.The overall modular design, the total number of parts is small, the failure rate is low, the structure is compact, and the maintenance is easy. 7.High-strength new cylinder design, improved displacement, better reliability, low noise, and longer service life. 8.Adopting waste gas bypass turbocharger, supercharging is smoother at low speed, and power output is more stable at high speed. 9.Power output in the rear gear chamber, with significant noise reduction effect. 10.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. 11.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 tailored according to application requirements.Engine model diversity
