Is the JLH-4G20TDJ Engine a Volvo Product?
1 Answers
JLH-4G20TDJ engine is not a Volvo product. While this engine incorporates some Volvo engine technologies and design elements, it is not entirely a Volvo engine. The JLH-4G20TDJ is a Geely engine model with a maximum power output of 160 kW, maximum torque of 325 N·m, and maximum horsepower of 218 Ps. It features direct fuel injection technology and utilizes a turbocharged intake system. For daily maintenance of the JLH-4G20TDJ engine, the following methods are recommended: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD-SF grade motor oil based on the additional equipment in the intake/exhaust system and usage conditions. For diesel engines, choose CB-CD grade diesel oil according to mechanical load, with the selection standard meeting or exceeding the manufacturer's requirements. Regularly change engine oil and filters. The quality of any grade lubricating oil will deteriorate during use. After certain mileage, performance degradation may cause various engine problems. To prevent malfunctions, change oil periodically according to usage conditions and maintain proper oil level. When oil passes through filter fine pores, solid particles and viscous substances accumulate in the filter. If clogged, oil may bypass the filter element through the safety valve, carrying contaminants back to lubrication areas and accelerating engine wear and internal contamination. Periodically clean the crankcase. During operation, high-pressure unburned gases, acids, moisture, sulfur and nitrogen oxides from combustion chambers enter the crankcase through piston ring-cylinder wall gaps, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in oil, while larger quantities may precipitate, clogging filters and oil passages, causing lubrication difficulties and accelerated wear. Regularly use radiator cleaner to remove rust and scale deposits. This not only ensures proper engine operation but also extends the overall service life of both radiator and engine.
