What are the reasons for the lack of acceleration in Sinotruk HOWO?
2 Answers
The reasons for the lack of acceleration in Sinotruk HOWO are as follows: 1. Insufficient fuel pressure. 2. Clogged fuel injectors. 3. The temperature sensed by the engine oil temperature sensor does not match the engine temperature when the vehicle is cold. 4. Faulty signal from the atmospheric pressure sensor. Additional information: 1. Reason: The inability to accelerate and the failure to increase the speed in electronically controlled diesel engines with electronic fuel injection. The specific cause depends on the brand and model of the diesel engine, as different models may have different faults. 2. The task of electronically controlled diesel engines with electronic fuel injection is to electronically control the fuel injection system, achieving real-time control of the fuel injection quantity and timing according to operating conditions.
Having driven for decades, I've encountered the lack of acceleration in HOWO trucks several times, mostly due to fuel system issues like clogged diesel filters or dirty injectors restricting fuel supply. It could also be caused by an old air filter failing to draw sufficient air, leaving the engine gasping. Turbocharger failure is worse – RPM rises but power doesn't deliver, like running with a suffocating mask. Underinflated tires or overloading can also make the vehicle sluggish. Last time I checked, the engine oil hadn't been changed for too long, becoming overly viscous with poor lubrication that dragged the engine down. For a quick test, try flooring the throttle during simple starts – if the response is sluggish, immediately inspect the fuel tank and coolant reservoir before getting stranded or causing accidents mid-journey. Regular fuel system cleaning and filter replacements prevent most issues; delaying repairs leads to costly overhauls and headaches.
