| Product features and advantages | |
| Fuel system | It adopts a new electronic unit pump fuel system with high injection pressure and precise control over fuel-injection quantity and injection timing. It has features of P-type injector without pressure chamber, complete combustion, enough power, low fuel consumption, low emission, intelligent control of electronic control system, warning of abnormity in water temperature, oil temperature and air inlet temperature and pressure, safer automatic alarm on potential failures, intelligent fault self-diagnosis and control, and protection strategies against abnormity in water temperature, oil temperature and air inlet temperature and pressure which protects the engine better |
| Intake system | Optimized combustion chamber and swirl rate airway have better intake swirls, and improve the combustion efficiency. The intake system has a high power intensity, strong power, and low fuel consumption rate and be more environmentally. Supported with high-performance turbocharger and advanced combustion system, the fuel consumption becomes less and the power becomes bigger |
| Cooling system | The engine block and the cylinder head are designed with a high-flow cooling system which can protect the engine from "high temperature" during all-weather high-intensity work |
| Design features | With the precise process technology and high quality alloy cast iron engine block and cylinder head, the complete machine has features of high enhancement degree, small size, light weight, low vibration and low noise |
| Reliability | It uses a high-capacity two-stage fuel filter with strong fuel water separating power, high filter efficiency and long maintenance period and is more economical. Its reliability and service life reached the advanced level among like products in China and the top overhaul period is 8000 hours |
| Supporting adaptability | Matching, optimization and customization of the engine and the assembly are made according to the assembly configuration and the actual use; and multiple configurations are available for flywheel, flywheel cover and generator |
| Start performance | It has good start performance and can start smoothly without any preheating measures when the environment temperature is no lower than -10ºC |
| Maintenance service | It is easy to repair and service. Its components and parts are highly universal with adequate parts commercially available; the electronic control system can offer intelligent diagnosis in real time |
