At what RPM does the Haval H4 turbocharger engage?
2 Answers
Haval H4 turbocharger engages at 2000 to 2500 RPM. After starting the engine, do not abruptly press the accelerator pedal. Allow the engine to idle for three minutes first. This helps raise the oil temperature and improve its flow properties, ensuring adequate lubrication for the turbocharger before increasing engine speed to start driving. The main function of the turbocharger is to increase engine air intake, thereby enhancing engine power and torque, making the vehicle more powerful. The Haval H4 measures 4410mm in length, 1845mm in width, 1695mm in height, with a wheelbase of 2660mm.
I've been driving for over ten years and have owned a Haval H4 for almost two years. The 1.5T engine in this car is particularly interesting. The turbo starts kicking in at around 1000 rpm. When I drive in the city, the engine idles at just 800 rpm at startup, but with a slight press on the accelerator to reach 1200 rpm, you can clearly feel the push-back sensation. Especially when starting at traffic lights, the early turbo engagement gives a significant advantage—just a light tap on the gas to reach 1500 rpm, and the car shoots forward like an arrow. Once, when driving on a mountain road fully loaded with four people, climbing at 1800 rpm was effortless. This low-rpm, high-torque design is especially practical for family cars, offering both fuel efficiency and power.
