What are the reasons for the diesel engine's inability to increase speed?
2 Answers
Diesel engine's inability to increase speed is caused by fuel line blockage. Below is relevant information about the car throttle: Throttle: It refers to the control device that regulates engine power (thrust). Throttle pedal: Also known as the accelerator pedal. It is part of the car's fuel supply system. By controlling the amount of pedal depression, it regulates the engine throttle opening, controls the intake air volume, and the computer controls the fuel quantity, thereby controlling the engine speed. Reasons for pedal sticking: Divided into three categories - human error, design defects, and inadequate craftsmanship. The driver information interface displays the odometer, trip meter, exterior temperature indicator, and other gauges.
I've been driving a diesel pickup for over a decade and frequently encounter issues with the RPM not increasing. The most annoying thing is when you're driving and suddenly lose power, with no response even when flooring the accelerator. It's likely a fuel system problem: when the fuel pump's pressure relief valve gets stuck, fuel pressure can't build up, naturally preventing the RPM from rising; if the injectors are clogged with carbon deposits, it's like a person struggling to breathe; and if the diesel filter hasn't been changed for too long, it gets as dirty as a rag, blocking fuel flow. I remember once when a fuel line connector leaked, causing the engine to stall while driving—turned out the return line screw was loose. Oh, and too much water in the fuel tank can also make the engine cough!
