What is Valve in Vehicle Engines?

 Before examining what the valve in engines is, the word meaning of the valve should be looked at. valve (valve); The valve, which is used to open and close something, in other words, the valve can be defined as a key. The system called valve in internal combustion engines is also known as valve by the public.

What is the Duty of the Valve? The valve is a unit that acts as one of the most important parts of the engine. When the cylinder movement occurs in the engine, the valve is responsible for sending the fuel needed for the combustion to occur in the combustion section to the relevant section. In addition, the gases released as a result of combustion are sent out from the combustion section by means of valves. The valve system that sends the fuel to the combustion area is called the intake valve, and the valve that undertakes the task of removing the gases resulting from the combustion from the combustion area is called the exhaust valve. Is it necessary to pay attention to the number of valves when buying a vehicle? When you look at the engines, it is possible to see inscriptions in the form of 8, 12, 16, 20 valves. The number of valves in the engine is usually twice the number of cylinders, consisting of one intake valve and one exhaust valve. However, as a result of the need for high energy in the last period; engine volumes have grown and it is seen that four valves are placed per cylinder, not two. Increasing the number of valves results in fuel savings. Many people may wonder what kind of benefits there might be to have more valves. It is possible to explain this as follows; By increasing the number of valves, more fuel is sent to the combustion zone, resulting in more perfect fuel and air components. In addition, due to the increase in the number of exhaust valves, the residual gas in the combustion section is significantly reduced. This results in a significant increase in engine efficiency. Since the combustion event in the combustion zone is more efficient, the vehicle accelerates more quickly and reaches high speeds in a shorter time. When Is Valve Adjustment Required? In order to understand whether the vehicle's engine needs valve adjustment, it should be checked whether there is a valve sound from the vehicle's engine; that is, if there is a sound similar to the sound of two metals colliding with each other, a certain decrease in engine traction and an excessive increase in fuel consumption may be indications for valve adjustment. If the vehicle is being pulled back by a force despite pressing the gas, these symptoms may indicate that valve adjustment is required.
