Think of room temperature syrup vs heated up syrup. Air and fuel take up more space than just air. However, I'd like to hear the answer from someone that has lots of time studying fluid dynamics and the other appropriate courses. In petrol engines, why is the exhaust valve hole small compared to the inlet valve? You can always get bigger injectors, but you cannot as easily increase airflow.
The bigger valve is the inlet valve and the smaller one is the exhaust valve.
The spark plug lies between the two. The main reason for the size. Hence the inlet valves have larger diameter in respect to that of exhaust valve. After completion of the expansion process inside the combustion chamber the.

Because it's more important to get more fuel/air in the engine. That is why in 3V engines there are 2 intake and 1 exhaust. It is easier to push.
If you are having this repair done, it may be a good time to have other needed repairs completed as overlapping labor discounts would likely be applied.
However, I'd like to hear the answer from someone that has lots of time studying fluid dynamics and the other appropriate courses.
The reason is air flow.
The final stroke is the exhaust stroke. Get started.

View Public Profile. THIS, is what pushes the piston down, the piston has to get the hell out of the way of the expanding gas or be destroyed.
The intake valve needs to be larger than the exhaust valve to handle the same gas. So it would seem that if you have to move a larger amount of gas out, then a larger exhaust valve would be in order.

So why is the intake larger. Intake and exhaust valves are the final component in the valve train system. face, with the intake valves often being larger than the exhaust.
Hence the intake valve hole has to be bigger than the exhaust valve hole.
Since engine output depends on the amount of oxygen in the combustion chamber, you would like to make it as easy as possible for air to enter the chamber.
Bent valves occur when the piston makes contact with the valves. There is no formula to calculate the diameter of exhaust valve. So the heat of the valve increases. Build, battle, and barter through the ages of history to develop an empire in this award-winning game.
Intake exhaust valves bigger
|In many modern engines, each cylinder has two intake and two exhaust valves per cylinder.
Why is the intake valve of an engine generally larger than the exhaust valve? The first step of diagnosis when damaged valves are suspected would be a leak down test.
CarDash CarDash makes it easy to take care of your car. The bigger valve is the inlet valve and the smaller one is the exhaust valve.
