Car Engine Problems

Engine is the heart and soul of your car. It mixes fuel and air, compresses them, and ignites the mixture to create a force that is used to move the car. The main part of an engine is the cylinder, in which fuel and air are supplied. The pistons in the cylinders move up, and compress the fuel and air mixture. As the mixture is compressed, the spark plugs ignite it. The combustion force the pistons down, that drives a crankshaft, attached to the car axle.

Car Engine Problems
There can be a number of reasons, why a car engine may not function properly. Here are some of the common problems that may occur in your car engine.

• Bad Fuel Mix: Bad fuel mix could result due to the presence of certain impurities in the fuel, or because the fuel system is not providing correct amount of fuel to the fuel mix. A bad fuel mix could also occur when the air intake is improper, leading to more air in the fuel mix than the fuel.
• Lack of Compression: It is important to compress the air and fuel properly, so that the mixture can be ignited. Faulty compression could occur, if there is a hole or leak in the cylinder or piston rings are worn out, due to which air or fuel leaks pass the piston when the mixture is being compressed. Failure of the intake and exhaust valves to seal properly, will also result in leaking of air or fuel.
• Lack of Spark: The spark is important to ignite the air-fuel mixture. If the spark plug or the wire leading to it is worn out or torn, a spark cannot be caused. For the air-fuel mixture to be ignited, the spark has to occur at the right time. If the spark occurs too early or too late in the ignition cycle, the fuel would not burn.
• Overheating of the Car: The cooling system prevents the car engine from getting overheated, as too much heating reduces the efficiency of the engine. A faulty cooling system could be due to a leakage in the cooling system, poor performance of the fan or worn out fan belts.
• Changes in the Oil Type and Oil Grade: The oil grade and oil type used for a car, should be as per company recommendations. A car engine may react, showing some problem, if oil of proper grade and type is not used. Moisture or dirt in the oil can also hamper performance of the engine.

Troubleshooting Car Engine Problems
The major causes of car engine problems, are worn out or clogged car parts. Worn out parts may cause overheating of the engine, engine surging and other problems. For example, damaged seals and valves cause excess fuel consumption. Hence, it is advisable that the car engine should be checked regularly for worn out or damaged parts. If any such part is found, then it should either be repaired or replaced. One should also be careful that all parts of the car engine are clean and unclogged. For example, if the oil filters are not clean, then it will hamper the flow of engine oil that will in turn reduce the efficiency of a car engine. It is always helpful to read the manual and follow the recommendations before repairing or replacing any part of a car engine. One must always remember, that adding any part to a car engine that is incompatible with the type and make of the engine can damage the car engine.

The internal combustion engine that is used in cars, is a result of the efforts taken by Daimler and Benz of Germany. Besides powering cars, it is used in numerous other purposes. Efforts are on to make more efficient engines, that provide greater power by consuming lesser amount of fuel.
