Product Description

PHFZ4P Series Diesel Engine is a four-stroke direct-injection type high-speed diesel engine. Based on the former ZH4102P series diesel engine, this series adopts new electronic unit pump technology and enables itself to meet the Stage Ⅲ emission standard for NRMM diesel engine. Power HF makes a matching design considering the characteristics of a bulk material semi-trailer. By making corresponding changes in some components and parts of the engine, this series is now made an ideal supporting power for small and medium power construction machines at home and abroad. It is strongly universal with large inventory commercially available, rugged and durable, having plenty of accessories. Its reliability and service life have reached the advanced level among those of the like products in China and the top overhaul period is as long as 8000 hours.
 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 ratio 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
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
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
