People with diesel cars need to know these 5 errors and how to fix them
(Baonghean.vn) - The strengths of diesel engines are strong engines, good traction, fuel economy, suitable for mountainous terrain... When using diesel-powered cars, drivers should know some common failures and how to fix them to save costs and ensure safety.
1. Engine is difficult to start
 |
Usually the machine is difficult to start because the power source including the battery and the contact connectors may be damaged, not in contact or dirty. In addition, the cause may also be due to poor grounding.
To fix this, check and charge or replace the battery. Clean and tighten the battery terminals.
2. Low idle speed
 |
The cause of low idle speed is a 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 radiator or a clogged, damaged thermostat valve. This will affect the engine and the valves, pressure, gaskets, and piston rings. So add 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 black smoke coming from the engine, it can be concluded that the car has a clogged air filter or a clogged rubber hose. At this point, 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, improperly adjusted high-pressure pumps, worn air conditioners, 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.
