If the compression rate is high, then all the power from the explosion is being used to drive the pistons. The cylinders in an engine have to be sealed tight so they can contain the explosions happening inside them. Poor Cylinder Compression (Both Diesel & Gas) If your car engine doesnвЂ™t sound like usual, there is a chance that a spark plug is worn out and the car is running on one cylinder less than usual. Mostly you will notice worn spark plugs when your car is misfiring. If you are losing power, bad spark plugs could be a problem in some rare scenarios.

They create the spark that causes explosions inside the combustion chamber. The spark plugs are part of the engine, which can cause problems with the engineвЂ™s power. Fuel pumps usually have a long life, so checking the fuel pump on your car shouldnвЂ™t be your first action. If the pressure is low, the fuel injectors will not be able to spray the correct amount of fuel into the combustion chamber, resulting in a loss of power.ДЄ faulty fuel pump will not pose problems at low speeds, but you might be left wanting when you are looking for quick acceleration.

The fuel pump has to be powerful enough to be able to send the fuel at high pressure. The fuel pump delivers fuel from the fuel tank to the engine. If there is even a slight miscalculation, the combustion cycle can get disrupted, resulting in loss of power and, in the worst-case scenario, broken cams or pistons. They need to spray the precise amount of fuel into the chamber for combustion to happen. They do this by sending in fuel at high-pressure, much like a spray. Faulty Fuel Injectors (Both Diesel & Gas)ДЇuel injectors introduce fuel into the combustion chamber. If the oxygen O2 sensor fails, it can cause a lean condition in the engine, which will cause the engine to lose power when accelerating. The oxygen sensor also affects the fuel injection system, so its proper function is necessary for your carвЂ™s smooth running. If the MAF readings match with the oxygen sensor readings, then this means your car is in perfect running condition. It is therefore located in the exhaust pipe. The MAF senses the amount of air entering the engine, and the oxygen sensor measures the number of gases that exit the engine. Regularly cleaning them can help improve their function. Sensors can get worn out due to heat and dust. If the MAF is faulty and not measuring the airflow properly, you could experience a serious loss in power. Once it gets that measurement, it sends this information to the ECU, which notifies the throttle to open accordingly. The Mass Airflow Sensor (MAF) measures the amount of air the car needs to accelerate. However, if there is any obstacle in the way like a clogged catalytic converter or a clogged exhaust, then your engine loses power. Therefore, if the car can excrete gases faster than it produces them, the car runs fast and smooth. The sooner the exhaust excretes these gases, the sooner the engine can restart combustion. The exhaust removes all the harmful and unnecessary gases from the engine. Clogged Catalytic Converter or Particle Filter The air filter goes bad after a few thousand miles, so it is best if you get it changed every time you go for an oil change. To ensure this, an air filter is placed right before the throttle body.ДЄs soon as the throttle opens, the air is sucked in, and it passes through the dedicated air filter, which cleanses the air of dust and other harmful particles. Therefore, the air that goes into the system should always be clean. Dust and other particles can damage the combustion chamber. The engine needs clean air to function properly. Clogged/Dirty Air Filter (Both Diesel & Gas) If the fuel filter is clogged, you can get it changed by a mechanic who will charge you a very paltry sum. The fuel filter is located in the engine bay or near the fuel tank in your carвЂ™s trunk. So, when this happens, the first thing you should do is check your fuel filter. You will feel as if you are losing power while you accelerate. If the fuel filter gets clogged and the fuel does not reach the engine chamber in the right quantity, the engine will not perform at its optimum level. Clogged Fuel Filter (Both Diesel & Gas)ДЄ fuel filter has the responsibility of filtering the fuel before it goes into the engine and combustion chamber.
