Reasons Why Electronic Fuel Injection Diesel Engines Won't Ignite

Why won't a direct injection diesel engine ignite? Let's explain it here at Googol Power Technology!

(1)Engine oil circuit blockage

Check if the oil pipe is clear. If you hear a hissing sound from the fuel injector, it means the fuel pipe is working correctly.

(2)Cylinder compression

Check the compression in the cylinder. If releasing the pressure relief device still allows the flywheel to rotate, there might be a problem with cylinder compression. Consider replacing the cylinder piston and piston rings.

(3)Lubricating oil

Timely oil changes are crucial. Thick lubricating oil hinders smooth engine starts.

(4)Fuel pump

Check for air in the pump. If there's air in the pump, the diesel won't start.

In winter, when the temperature is extremely low, diesel engines may fail to start in the morning. Here's a trick:

(1) It's challenging to start cars in the morning. Pay attention to the first position, 'open' on the dashboard key with a power socket. If the diesel engine preheating indicator blinks for about 10 seconds, it indicates sufficient heat in the power socket. Then, engage the clutch and accelerator, finally, refuel, ensuring the oil well is in good condition.

(2) Usually, at this time, refueling is not smooth. Repeat the same action several times. Be aware that the temperature is relatively short, slightly longer in winter. Also, avoid excessively frequent attempts to start the engine. If the battery is dead, seek assistance to push-start, and pay attention to the starting technique.

(3) Defrosting: While heating the car key inside, lower the car's windows and open the door to prevent it from locking automatically when getting out. Use a plastic card or window scraper to remove frost from windows and windshields.

(4) Warm-up: After starting the car, when the water temperature is zero, avoid heating operations. Drive the car at speeds below 20 and in second gear, until the water temperature rises for normal operation. At this point, the heater will be hot. Properly defrost the glass, if not scratched, as it's impossible to see the road during this period. Avoid making such mistakes.

(5) Winter precautions: In winter, diesel generally uses No.35 diesel. Diesel wax forms and solidifies at lower temperatures. Diesel at-35 degrees Celsius can be used at low temperatures, so it's more likely to prevent the car from starting. In winter, keep warm and park the car in indoor parking lots.
