What is the jl486zq4 engine?
2 Answers
jl486zq4 engine is a Blue Whale engine, independently developed by Changan Automobile, and belongs to a domestic engine. Models such as Changan CS95 and Changan CS85 use the jl486zq4 engine. The engine model of Changan CS95 is jl486zq4, with a maximum power of 171kW, a maximum torque of 360 Nm, and a maximum horsepower of 233. For daily maintenance of the jl486zq4 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid faults, oil should be changed regularly according to usage conditions, and the oil level should be moderate; 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 is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve, bringing dirt back to the lubrication area, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking filters and oil holes, making engine lubrication difficult and causing wear.; Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.
I believe the JL486ZQ4 is a 2.0-liter turbocharged engine developed by Changan Automobile, commonly used in their popular models such as the CS75 PLUS and UNI-K series. It is designed based on the BlueCore technology platform, with a maximum output power of around 230 horsepower and peak torque of approximately 360 Nm. Equipped with direct fuel injection and a dual VVT variable valve timing system, it not only improves fuel efficiency but also enhances low-speed response. In actual tests, it performs smoothly during mid-to-high-speed acceleration, making it suitable for both urban daily commutes and long-distance highway driving. Maintenance-wise, regular checks of the turbocharger and cooling system are essential, as long-term use may lead to carbon buildup. Overall, this engine combines reliability and performance, making it a trusted choice for many car owners.
