A car engine works simply by igniting the air-fuel mixture, and this ignition leads to an explosion inside the engine's internal cylinders, and this explosion is powerful and works to move the crankshaft and several other parts, and the movement of these parts is transmitted from the engine to the transmission and then to the wheels.
During the operation of the engine, many parts are exposed to pressure, movement and heat, not to mention the aging of the engine, and if one of the engine components or even the parts connected to it are damaged, its performance will be weakened and may stop working.
You should know that Motorgy offers you used cars for sale in Kuwait that have been examined by experts for more than 70 remarks that include the engine, transmission, electrical and interior, and this will make it easier for you to choose the car you want after reviewing the inspection report to ensure that it is free of malfunctions and troubles that will follow you for a long time.
What are the causes of poor engine performance?
The following are the causes of poor engine performance:
Clogged air filter
Every engine that runs on fuel needs a filter to clean the air that will enter it for the combustion process; because if dirt and dust enter the combustion chambers, the engine may completely fail, and when the filter works to purify the air, dirt and dust remain in it, and if it accumulates greatly, it will not be able to introduce the required amount of air into the engine, which will affect the combustion process and the engine's performance, which will definitely weaken.
Clogged or damaged fuel filter
The function of the fuel filter is to filter the impurities and dirt in the fuel before it enters the engine, and if the fuel filter is clogged and the fuel does not reach the engine cylinders for the combustion process, the engine will not work as it should and its performance will weaken, and you will feel a loss of power during acceleration and sometimes you will feel intermittent vibrations.
Bad spark plugs
If you feel that your car does not respond when you press the gas pedal, it may be due to worn spark plugs that are nearing the end of their life, they are prone to wear and tear, when this happens, they will not be able to generate the spark that ignites the air-fuel mixture and starts your car's engine, and this means loss of power and reduced engine performance, in addition to making noise from the engine and increasing fuel consumption.
Damaged or clogged exhaust system
The exhaust system works with all its parts to take all harmful and unnecessary gases out of the engine to the outside of the car, and the sooner the harmful gases come out of the engine, the more the engine can work comfortably and complete the process of burning the fuel and air mixture better, but if there are any kind of obstacles inside the exhaust system such as damage, breakage, cracking, or even clogging of the catalyzer and muffler, the engine performance will weaken and lose its power.
Weak gas pump
This pump simply pumps gas from the tank to the engine, and this pump must work smoothly and without issues in order to be able to pump fuel at high pressure and in measured proportions, but if the pump is weakened or damaged, it will not be able to send fuel properly to the engine, and this means that the atomizers will not properly spray fuel into the combustion chamber, resulting in poor performance and loss of power.
Damaged or clogged fuel injectors
The fuel injectors are responsible for introducing fuel into the combustion chambers, and this process occurs at very high pressure, and the amount of fuel that the injectors blows must be accurate for the combustion process to succeed, but if an injector is damaged or clogged, the engine will not get the required amount of fuel and its performance will be significantly impaired, and the cams and pistons may break, and one of the most common causes of damage to fuel injectors is carbon buildup due to low fuel quality.
Bad oxygen sensor
The function of this sensor is to monitor the level of oxygen that comes out of the engine after the combustion process inside the engine cylinders, then sends the data to the computer, and if this sensor is damaged, it will transmit wrong data to the computer and there will be a malfunction in regulating the air-fuel mixture, which leads to significantly slow acceleration and poor engine performance.
Bad mass air flow sensor
The MAF sensor measures the amount of air the engine needs to accelerate, and when it gets this data, it sends it to the car's computer to analyze the data to either decrease or increase the ratios, and if this sensor is damaged, it will not measure the airflow ratios correctly, the car's computer will give wrong commands that will reduce the engine's performance.
