The engine is one of the most important parts of the car, without which the car cannot move or even start. Ensuring that the engine is in good condition is the best way to ensure that the car can be operated effectively. It is important to know and understand what each part of the car does, so that you can understand what may be wrong with it. Well, having basic knowledge of the engine can save you money, as you are able to fix some of the minor problems yourself, instead of taking the car to the repair shop.
Some of the important parts include the valves. The intake valves in the engine control the air and fuel amount that is released into the piston chamber, while the exhaust valves release the burnt fuel and the gas from the piston chamber. The emissions are released out through the tail pipe. The piston, flywheel and crankshaft control the movement of the car, by providing the power device and ensuring that all the parts work together at all times to provide the momentum.
There are a number of combustion chambers in the engine called the cylinders. Inside these cylinders is where ‘mini-explosions’ that occur as a result of ignition of air and gas, take place. The cylinders are usually made from aluminum or cast iron, which gives them durability. The cylinder is one part of the engine that is very susceptible to wear and tear due to the friction that goes on constantly between the cylinder and the piston.
The carburetor is the part of the engine that governs or controls the amount of air and fuel that is ignited in the cylinder. It ensures that the amount of fuel supplied corresponds with the air available. This helps to ensure that the two elements mix in the correct proportions. Too much fuel can cause the engine to flood, while if it is too little, it will not ignite.
The engine creates a lot of heat when the car is in motion. Anti-freeze that is stored in the radiator cools the engine block, through use of the radiator fan. The anti-freeze moves constantly through hoses and compartments, ensuring that the engine block remains as cool as possible.
The pistons need a spark in order to light the mix of compressed fuel and air, and these are provided by the starter systems. The car battery is responsible for turning the starter, which begins the movement of the crankshaft, and the spark plugs ignition.
An engine cannot function effectively without lubrication, which helps to keep the parts free of friction and moving well. The oil pan need to be filled to a certain level to make sure that the block that has the cylinders, crankshaft and pistons, are lubricated effectively during each rotation. The lubrication system also consists of transmission fluid that keeps the gears, which rotate the wheels lubricated. The lubrication system provides the fluid pressure that is used to steer the vehicle, as well as applying line pressure for the brakes.
