(Baonghean.vn) - The strengths of diesel engines are strong engines, good traction, fuel economy, suitable for mountainous terrain... When using a car running on diesel engines, drivers should know some common damages and how to fix them to save costs as well as ensure safety.

1. Engine is difficult to start

Usually the machine is difficult to start because the power source including the battery and contact connectors may be damaged, not in contact or dirty. In addition, the cause can also be due to poor grounding.

To fix it, check and charge or replace the battery. Clean and tighten the battery terminals.

2. Low idle speed

The causes of low idle speed are clogged filter and low fuel in the tank.

The best solution is for the car owner to replace and clean the filter, add fuel and adjust the engine speed at idle.

3. Engine overheating

An overheated engine can be caused by a lack of coolant, a dirty or clogged radiator, or a damaged thermostat valve. This will affect the engine and the valves, pressure, gaskets, and piston rings. So, add more water and check for leaks, check the thermostat valve, flush the radiator, and clean the radiator.

To be more careful, you should regularly check the vehicle and engine before operating, or at least once a week to limit this situation.

4. Engine exhaust black smoke

When you see the engine emitting black smoke, it can be concluded that the car has a clogged air filter or a clogged rubber intake hose. At this time, you should clean or replace the above two parts if necessary.

5. Fuel consumption

First, poor quality diesel will cause your car to consume more fuel than usual. In addition, a misadjusted high-pressure pump, worn air filter, leaking fuel lines and high engine oil levels are also factors that cause fuel to wear out quickly.

Therefore, it is necessary to check the end-of-stroke pressure, readjust the high-pressure pump and change the fuel to get the vehicle running well again.
