Engine mechanics of racing cars in formula1

[admin]

It is too evident that all the activities related to car racing revolve around just one key word – speed. Therefore, it is quite natural that there goes a lot of complexity in the making as well as functioning of the racing cars.
Out of all, the F1 engines are the most complex of the racing engines that we see moving with lightening speed in the circuit. The machineries of the F1 racing cars are so complicated because they have close to 5000 parts among which 1500 are the moving elements. All these machinery parts together can produce more than 750 hp of energy and can reach more than 20,000 rpm.

Test drive has proved that at the maximum speed the F1 engines can consume around 60 liters of petrol per 100 km of racing. FIA has ruled that in place of a 20 to 30 hp gain, it is not allowed for the manufacturers to develop their engines further and have imposed a rev limit of 19,000 rpm.

Presently, the f1 engines can produce about 720 hp with the help of 8 cylinders in a 90-degree V-angle. However, the limitation of the performance is because of the limits imposed by the organization. Or else, the figures by now would perhaps have crossed beyond all our imaginations.

The main body of the engines is made of forged aluminum alloy as it much heavier in comparison to steel.
This is an added advantage of the engines. To limit the costs of the engines the FIA has forbidden the use of non-ferrous materials. In the engine as the exact oil requirement is not known, it is such that the oil is for the 70% of the engine while the leftover 30% is in a dry-sump lubrication system, which is responsible for the changing of oil in the engine three or four times in a minute.

There are certain differences of the F1 engines with the other road engines. The main difference here is the higher volumetric efficiency, which is used to describe the amount of fuel or air, present in the cylinders with relation to the regular atmospheric air.
However this does not allow turbo, they are not much different from the normal road engines. The engines also differ on the thermal efficiencies. This includes the factors like the usable horsepower, ignition timing, thermal coating, chamber design and plug locations.

You must remember that among all the amount of energy generated, the car engine uses part of it and the leftovers are measured in the dynamometer. Actually, the difference of the values on the dyno and the workable power of the cylinder give the value of the mechanical energy of the car.
The efficiency of the engine is dependent like the bearing friction, rocker friction, and other moving parts like the piston skirt area upon many factors. Limiting the internal energy friction in turn generates a surplus in horsepower and when the F1 engine is stressed for power, the stress is on the consumption of fuel.

Inline engines are where all cylinders are placed next to one another.
These are however outdated patterns and have not been used in the Formula 1 car since the 60s. The engines are long and thus need a heavy crankshaft. If the external factors allow, the boxer engines are the best ones to apply to your car.
These are actually popular in the F1 cars as they have a low center of gravity and the production costs of the engines are comparatively low. Nowadays the V-type engines are used in the F1 cars.
