How F1 engine and car works.

Custom Search

F1 engines are just like our normal car engines (the piston cylinder engines). This is a 2.4 litter, 90 degree V-8 engine. So we have 4 cylinders perpendicular to each other on 90 degree angle. It has four valves in each cylinder, 2 for exhaust and 2 for inlet, same as in modern car engines. The engine runs up to 18000 rpm which is much more compared to normal car engines. The for stroke ratio of the F1 engines are very high (ie. cylinders are very wide, shallow and due to this the pistons have to travel a short distance or the stroke length is reduced)

F1 engines use a dry sump oil system (the oil sump will not be underneath the engine – a separate tank to pump in the oil)

You might have noticed, the port above the head of the F1 driver, which is the air suction port to the engine, for better suction and volumetric efficiency also you get cool, clean, and laminar flow of air.

What is volumetric efficiency?

How much ration of air you have in the cylinder compared to the same size cylinder of air at atmospheric pressure. The piston is sucking in the air as it moves down, it pulls in the maximum amount of air it can. The maximum it could pull in is 1 atmosphere. Normally that cannot be achieved; it can be like 80 – 85% (ie. 85% of atmospheric pressure that is the amount of air that it has sucked in). So if we have a turbocharger or supercharger, the volumetric efficiency can be increased even above 1. With this more amount of air can be sucked in and even 200% of volumetric efficiency can be achieved.

The valve train is a difference in F1 engines.
