What is the jl473zq7 engine?
2 Answers
jl473zq7 is a Blue Core engine. Advantages of the Blue Core engine: Its high-pressure direct injection technology leads the industry. Most engines only allow fuel to be injected twice, but this engine in the new CS75 can achieve up to 5 fuel injections in a single stroke. Among mass-produced engines worldwide, it has the highest injection frequency. Disadvantages of the Blue Core engine: A common issue with the Blue Core engine is that engine noise easily enters the cabin at high RPMs. It has a maximum power of 115kW and a peak torque of 225 Nm. The outdated multi-point fuel injection system performs poorly in terms of fuel economy. Additionally, during acceleration, the transmission downshifts slowly with significant lag.
I specialize in engine technology and have in-depth knowledge of the JL473ZQ7—it's a mainstream 1.5T turbocharged gasoline engine from Changan Auto, commonly used in the CS series SUVs, delivering around 150-180 horsepower. Its basic structure features an aluminum alloy cylinder block and direct fuel injection, improving fuel efficiency with a compression ratio of 10:1, and it runs on 92-octane gasoline. The power delivery is linear, providing quick acceleration in urban areas, with average fuel consumption of 7-8L/100km. However, the NVH control is mediocre, and road noise becomes noticeable at high speeds. For maintenance, pay attention to the turbo system—it's recommended to change the oil and inspect seals every 10,000 km to prevent oil leaks. This engine offers solid reliability for family vehicles, though additional soundproofing may be needed if you prioritize quietness.
