How to Overcome Turbo Diesel Engine Performance Declining? – Diesel engine performance decreases, making vehicle owners panic. Especially when in travel conditions, this will add to its own panic. There are things you can do to improve or restore the performance of a diesel vehicle. We will try to discuss it below.

Diesel cars with turbo performance can decline over time. When the performance of a turbo diesel engine drops, you don’t have to be sad. The reason is, that there are several steps you can take as a solution to treat a turbo diesel engine whose performance has decreased.

Overcome Turbo Diesel Engine Performance Declining

The first, of course, is to check the condition of the engine components and internals. Usually for diesel cars that use biodiesel, generally performance drops because of the soot that clogs the common rail system. If the engine is clean from the soot that clogs up and you are still not satisfied with the performance of your favorite car, remap the ECU or install a piggyback can be an alternative.

However, not infrequently the lack of education of car owners and workshop mechanics can result in an even greater decline in performance. It could be that the REMAP or piggyback application is actually in overtone or over boost conditions. And finally, the engine becomes unreliable and causes damage, especially in the turbo.

Overture or over boost itself means the ECU tuning conditions that are far above the engine’s potential. The result is that if you have over boost the turbo can be broken because it can’t face the increase in boost. And the result is even more sluggish performance. Finally handled by Rev, and had to replace several components before it could be normalized. If you have replaced components, of course, the costs that must be incurred will be greater.

So, what actually causes diesel engines to lose power? We’ll look at some of the causes in general in the following sections.

Causes of Diesel Engine Lack of Power

There are five causes that can make a diesel engine less powerful. Especially for conventional diesel engines. We need to know that there is a new diesel engine technology system called Common Rail Diesel which is available in almost all new diesel engines.

1. Dirty Fuel Filter

A dirty fuel filter is one of the main problems of diesel engines lacking or losing power. Dirty diesel filters reduce the flow and volume of fuel entering the engine. Finally, the engine experienced a lack of fuel mixture so its power was not optimal.

Dirty filters make the filtering process not good. Impurities can be able to enter the injection pump. Eventually, the injection pressure becomes problematic. An indication of a dirty diesel filter is a sign that the water separator indicator light starts to light up without any obvious signs of the cause.

Therefore, if your diesel engine is experiencing low power or loss of power, please first check the fuel filter. Clean the fuel filter to restore engine performance. But if the fuel filter is too dirty, you can immediately replace the fuel filter with a new one.

2. Low Fuel Pressure Pump

This pressure pump is mounted on the diesel filter or near the injection pump. Its function is to draw diesel from the fuel tank. If the condition is weak, then there is a delay in the supply of fuel to the engine. This condition causes the fuel and air mixture to be no longer ideal. As a result, combustion in the combustion chamber is not perfect and engine performance decreases.

An indication of a weakened pressure pump is that the engine is difficult to start in the morning. Of course, the problem with the diesel engine starting in the morning is not only from this factor. If this factor occurs, we even need to pump it to start the engine.

If this condition occurs in your diesel car, you need to replace the fuel pump. Replacing the fuel pump is quite costly and time-consuming. So, if you are a hobbyist, please replace it yourself by buying a diesel fuel pump at a spare parts shop. But if you are a very busy person, you can take it to a repair shop for a professional mechanic to handle it.

3. Injection Pump Problem

The injection pump is an injection pump to deliver pressurized diesel fuel to each injector. The pressure in the injection pump has different sizes depending on each car.

However, when the injection pump pressure is less or even more than the recommended pressure, the diesel engine must have a problem. An indication of a problematic injection pump is the appearance of thick black smoke and loss of power.

An injection pump is a component that is quite or very expensive. Although they are rarely damaged, they can also be damaged without prior notice. If it’s broken, it’s really hard to fix it. So you need to save to anticipate damage to this part because this part is really more expensive than other parts of the diesel fuel system.

4. Improper Injection Timing

The value and position of the injection timing in a diesel engine are very rarely changed, it turns out that it could be in an inappropriate position. Eventually, the diesel engine becomes less powerful. Injection timing is the time the injector opens the nozzle to spray fuel.

The condition of the injection timing that changes and does not match the engine specifications can make the car powerless and powerful. Sometimes even too much black smoke appears in the exhaust.

Injection timing can be determined by the timing belt or timing chain. Either the timing belt or timing chain can change over the time the vehicle is running. Therefore, you need to have it checked within a certain period of time. If you are having problems, you should replace this part to restore engine performance.

5. Low Engine Combustion Chamber Compression Pressure

Diesel engines that are less powerful are indeed affected by the problem of smelling fuel. The engine combustion chamber compression pressure is too low.

Compression pressure does affect diesel engine power. Diesel engines require high compression pressure, approx. 30 kg.m. Very far when compared to the compression of gasoline engines in the range of 10/11 kg.m.

When the compression pressure decreases, the fuel-air mixture is more difficult to detonate. What are the consequences? Of course, the engine power is reduced.
