DCEC QSL8.9-C340-III Industrial Engine
DCEC QSL8.9-C340 engine is a 6-cylinders in line engine, which is a 8.9 liter four-strokes L series Industrial engine with 114mm bore and 144.5mm stroke. Equipped with CCR , engine comes with turbocharger and Air-Air Intercooler. Rated power is 250 KW at engine 2100 RPM.
Advantages of QSL8.9 Industrial Engine
1. 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
2. Adopt high pressure common rail fuel system (HPCR) to ensure rapid throttle response at different speeds, better power and fuel economy, and lower noise
3. Adopting waste gas bypass turbocharger, the supercharging is smoother at low speed, and the power output is more stable at high speed
4. Mature intelligent electronic control technology improves the overall performance of the engine, and the engine specifications can be tailored according to application requirements
