If you’re losing power in your engine, it simply means that the power generating parts of the vehicle are experiencing difficulties. Like most engine problems, the four areas that have the most responsibility in generating power are the Air, Fuel, Compression and Spark Areas.
Therefore, you need to consider the various possibilities in these areas in order to stop the attack on your engine.
How To Get Power Back In My Engine ?
This section takes a look at the possible reasons why you’re experiencing power loss in your engine. With this knowlege , you can troubleshoot and find a fix for your car.
1) Fuel :
Your engine simply can’t generate any power without enough fuel. In other cases, the delivery or quality of the fuel will affect the generation of power.
- Clogged Fuel Injectors :
If the fuel injectors are clogged, it means that the delivery of fuel into the combustion chamber is restricted and with that going on, your engine will hardly be able to function.
The clogging can be due to deposits from either heat soak or contaminated fuel. In such case, the engine can misfire a few times every once in a while and even give you low energy signs while driving because the fuel delivery is not enough.
You can start by servicing the injectors in order to give you proper control of the fuel injection for improved performance.
- Worn-out Fuel Pumps :
After a given period of use, fuel pumps tend to wear out. In such cases, you might not notice this flaw when the fuel is being delivered at low pressures.
However, when you’re accelerating uphill, and fuel needs to be delivered at a high pressure, the pumps begin to fail. Simply put, if your engine loses power under heavy acceleration, this might be the cause of the problem. If that’s the case, you definitely need to have it checked out.
2). Air :
Air is just as important as fuel in the combustion chamber. They even face the same problems such as poor delivery or contaminated delivery. These factors could be due to a number of reasons explained thus;
- Dirty Air Filter :
As the name implies , air filter ensures that the air delivered to the combustion chamber for air/fuel mixture is clean enough and is rich in oxygen for proper combustion.
If the air filter is dirty, it won’t be able to function properly. A better alternative is to get rid of the factory installed paper types and get yourself performance air filters which are made of cotton and can be washed and replaced for reuse.
- Clogged Exhaust :
This part is just as important as the air filters because even if the air input is taken care of, the power in the engine will still be subsidized if the outflow is not maximized.
If the exhaust is clogged, the engine will have to work harder to push the exhaust smoke out. This will limit the power of the engine, cause the engine to make annoying noises especially when revving and produce thick black smokes polluting the atmosphere.
Air mufflers can fail due to a number of reasons such as rust or even faults in the internal piping, and needs to be taken care of to get power back in your engine.
3). Spark :
The third element required in the combustion chamber is the spark produced by the spark plug. If the air intake and outflow is highly maximized, and the fuel delivery is optimized, the engine still needs a powerful spark enough to deliver quality power.
- Faulty Spark Plugs :
Spark plugs tend to gather deposits in time and fire inconsistently. If your engine misfires too much, the power delivered would be pretty low. Therefore, you need to clean the plugs regularly to ensure that this doesn’t happen.
Alternatively, you could get performance spark plugs such as iridium laced plugs for optimal performance.
4). Carbon deposits on the Piston :
Some other times, power loss could be as a result of the impurities on the piston and not the quality of the spark plug. These deposits create hotspots that can knock out the engine eventually.
If the engine is strong enough, it won’t knock, but the power delivery will be reduced. In this case, you might need to do a proper cleaning of the combustion chamber, the piston rings and the cylinders.
- Compression :
For old engines, maintaining a powerful compression can be a challenge and lead to loss of power given the declined strength of the engine over the years. This could be as a result of several reasons such as the ones discussed thus;
- Carbon deposits on intake valves :
Similar to the case of the piston, if there are carbon deposits on the valve seats or the intake valves, they can be prevented from closing properly, and so air will escape during the compression stroke.
If this happens, the compression ratio will be drastically reduced, same as the power delivered. Similarly, if pressure escapes the valves, the delivery after combustion would be low in comparison.
- Worn-out Piston Rings :
This case is a bit similar to that of the intake valves. If the piston rings are worn out, air will escape the cylinder when the pistons are delivering their compression strokes.
The air escaping could also contain pressured air/fuel mixture that should be converted into energy. This escape leads to the crank case and the entire combustion chamber can be contaminated from this exposure.
The most imminent threat is that the pressure delivered is lowered and so is the power output. The rings will need to be replaced at the very least.
Basically, the areas discussed are the ones that mostly affect the power output of an engine and if they are taken care of, power will be restored. It’s more or less like servicing the engine, but in this case, the areas covered will be more specifically targeted at the power core of the engine.
