The 1.0-liter turbocharged engine of the Buick Excelle has the code LJ1, while the 1.3-liter turbocharged engine is coded L16. The 1.0-liter engine delivers 125 horsepower and a maximum torque of 170 Nm, with the maximum power achieved at 5,600 rpm and the maximum torque available between 2,000 and 3,600 rpm. The 1.3-liter turbocharged engine produces 163 horsepower and a maximum torque of 230 Nm, with the maximum power achieved at 5,500 rpm and the maximum torque available between 1,800 and 4,400 rpm. The Buick Excelle's engine is part of General Motors' new-generation Ecotec dual-injection turbocharged engine series. These engines are manufactured at the Shanghai GM Yantai Dongyue production base and are based on German technology, making them domestically produced engines. For daily maintenance of the Buick Excelle's engine, the following methods can be employed: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment in 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 meeting or exceeding the manufacturer's requirements. Regularly change the engine oil and oil filter. The quality of any lubricating oil will degrade over time with use. After a certain mileage, its performance deteriorates, leading to various engine issues. To prevent malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. As oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may rupture or the safety valve may open, allowing oil to bypass the filter and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Periodically clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, and oxides of sulfur and nitrogen from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls. These substances mix with metal particles from component wear, forming sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures proper engine operation but also extends the overall lifespan of both the radiator and the engine.
