What engines does Changan Automobile use?

Depending on the different models under Changan, the engines also vary. The engine model is 472Q16, a 1.4L version with a maximum power of 74KW, maximum torque of 135Nm, and maximum horsepower of 101. The 1.5L version has a maximum power of 78.5KW, maximum torque of 145Nm, and maximum horsepower of 107. The engine model specification is BlueCore, a 1.6L naturally aspirated engine with a maximum power of 94kW and maximum torque of 161N.m. The 1.4T engine has a maximum power of 116kw and maximum torque of 260Nm. Changan Automobile's engines are independently developed by Changan and produced in Chongqing, so they are considered domestic engines. For the daily maintenance of Changan Automobile's engines, 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 failures, change the oil regularly based on usage conditions and keep the oil volume moderate. When oil passes through the fine holes 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, it may burst the filter element or open the safety valve, allowing oil to bypass and still carry contaminants back to the lubrication area, 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 powder from worn parts to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil holes, 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's normal operation but also extends the overall lifespan of the radiator and engine.
Changan currently primarily uses its self-developed Blue Whale series engines, a technology I'm quite interested in. The Blue Whale engines come in several displacements including 1.4T, 1.5T, and 2.0T, which are used in flagship models like the CS75 PLUS. The standout feature is the high-pressure direct injection technology, with exceptionally high fuel injection pressure that atomizes gasoline into finer particles, resulting in more complete combustion for both fuel efficiency and strong power output. I've test-driven models equipped with the 1.5T engine, which delivers peak torque at just 1,400 rpm, making stop-and-go traffic remarkably effortless. The transmission pairing is also well-tuned, with nearly imperceptible gear shifts. Changan even offers a lifetime warranty on these engines, demonstrating the manufacturer's confidence in their quality - as a regular consumer, this gives me great peace of mind.
