Car Combustion System Components and Their Functions – Currently, cars have become an important part of people’s daily lives. Easy and efficient mobility has made the car the preferred means of transportation for many people. But, do you know what makes a car engine work well? One of the main factors is the car combustion system, which consists of various important components with crucial functions.
1. Fuel system
The main component in the car combustion system is the fuel system. This system plays a role in providing the fuel needed so that the engine can operate properly. The fuel system consists of the fuel tank, fuel pump, injectors, pressure regulator and fuel filter.
This component functions as a container to store fuel which is then channeled to the injector. Fuel tanks are usually made from corrosion-resistant materials and have a capacity according to the car’s needs.
This pump has a role in pumping fuel from the tank to the injector. The fuel pump can be either a mechanical pump or an electric pump depending on the type and model of the car.
The injector is a component that sprays fuel into the combustion chamber with precision and in the right quantity. This injector is controlled by the engine control unit to produce an ideal fuel mixture.
This component controls the pressure of the fuel entering the injector. The pressure regulator ensures that the fuel pressure entering the injector remains constant so that the fuel intake to the engine is also consistent.
The fuel filter cleans dirt and small particles in the fuel before it reaches the injector. This filter is important for maintaining injector performance so that it remains smooth and prevents damage to other components.
2. Combustion System
After the fuel is sprayed into the combustion chamber by the injector, a combustion process occurs which produces the energy needed to drive the car. The main components in the combustion system include the spark plug, cylinder, valve and piston.
The spark plug functions as a combustion trigger in the combustion chamber. The spark plug produces an electric spark that causes fuel to burn in the combustion chamber and produces power which is used to move the piston.
Cylinder is the most important part in a car engine. Modern car engines generally have several cylinders which function as a place for burning fuel. The piston movement in the cylinder moves the crankshaft which will then transfer power to the car wheels.
The valve is a component that regulates the flow of air and fuel mixture into the combustion chamber and releases exhaust gas after the combustion process is complete. The valve that works in sync with the piston ensures that the fuel mixture enters and leaves the combustion chamber at the right time.
The piston functions to channel the power generated from the combustion process to the crankshaft. This up and down movement of the piston converts the air and fuel pressure in the combustion chamber into a linear movement which is then passed to the crankshaft for further processing by the transmission system.
3. Cooling System
When the car engine operates, the engine temperature will increase. Therefore, a cooling system is necessary to keep the engine temperature within safe limits. The cooling system consists of a radiator, cooling fan, viscous fan, thermostat and coolant.
The radiator is a component that cools the cooling fluid flowing inside it. Radiators are usually made of metal which has high strength and heat conductivity so that it can help absorb heat from the cooling fluid.
The function of the cooling fan is to blow air into the radiator, thereby speeding up the cooling process. This fan is usually controlled by a thermostat which will turn the fan on or off according to the temperature of the engine.
The viscous fan is a part of the cooling system that regulates the speed of the cooling fan. Viscous fans use a viscous fluid whose viscosity changes according to engine temperature to control the fan rotation speed.
The thermostat is an important component in the cooling system that regulates the engine temperature so that it remains stable. The thermostat opens or closes the coolant pathway to the radiator depending on engine temperature.
The function of the coolant is to absorb heat from the engine and transfer it to the radiator to be cooled. The coolant must have properties such as temperature stability, corrosion resistance, and good boiling point improvement to keep the engine temperature within safe limits.
By understanding the components and their functions in a car’s combustion system, you will have an advantage in understanding how car engines work. It is important for vehicle owners to understand this system in order to maintain and maintain the car properly. Given the important role the combustion system plays in a car’s performance, extra attention should be paid to its care and maintenance to ensure that the car remains in good and safe function.
