Is the GM L2B One of the Top Ten Engines?
1 Answers
The GM L2B engine is one of the "China Heart" Top Ten Engines. The L2B engine is produced by Shanghai GM Dongyue Automotive Powertrain Co., Ltd., a newly established joint venture by General Motors in China. The GM L2B engine has a displacement of 1.5 liters, with a maximum horsepower of 112 Ps, a maximum power output of 82 kW, a maximum power speed of 5800 rpm, a maximum torque of 147 Nm, and a maximum torque speed ranging from 3600 to 4000 rpm. For daily maintenance of the GM L2B engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements; Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level; When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. In small amounts, it remains suspended in the oil, but in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
