Cooling

The carbon fibre duct (1) gradually widens out as it approaches the engine,

effectively creating a venturi and a suction effect on the small air inlet(2) The flat panels located nearly vertically in the front of the side pods are

the radiators (3) is the engine exhaust system

(4) While in this picture the radiator is covered with a protective hose, it is

not during running as air passes through the aluminium fins of the radiator

Lubrication

Oil is pumped from the dry sump oil

tank on the front of the engine into the

distribution network within the

cylinder block and heads, which

ensures it gets directly to all critical

engine components

Lubricant is fed to the bearings of thecamshafts to minimize friction and wear and

also to lubricate the critical cam-to-follower

interfaces, where the enormous forces

required to open the valves quickly enough

at 19,000 rev/min must be transmitted

through a layer of lubricant efficiently and

without failure


20/31

The used lubricant is sucked away from the

bottom of the crankcase by the scavenge

pumps, to be cooled in radiators and

returned to the oil tank, refreshed and readyto start its circuit of the engine again

The camera exits the engine, showing a fully

lubricated engine

Suspension

Forces to cope with

dW = (m * h * a) / t

with dW symbolizing the total weight transfer due to an acceleration a (m/s),

a total vehicle mass m (in kg),

h the height is the height of center of gravity,

t is the track width. (For longitudinal weight transfer, use wheel base instead of t).

Different types of weight transfer

1)Heave is the motion of the chassis when all four wheels go up or down in unison

2) when the car seemingly bends forward, or accelerating so that the car want toraise its nose.

3) The suspension on the outer side of the car compresses while the innersuspension extends

4) The front left suspension compresses as the right rear extends.

Traction control

The different systems mainly differ in the way of reducing

that power output to the wheels

Retard or suppress the spark to one or more cylinders

Reduce fuel supply to one or more cylinders

Brake one or more wheels

Close the throttle, if the vehicle is fitted with drive by wire

throttle.

Tyre use in formula one

The compound ( 1) is based on three main elements: carbon, oil and sulphur. More or

less soft depending on the characteristics of each circuit, this sector changes

considerably from one race to the next, whereas the structure evolves little by little

throughout the season. To keep the tyre together there are bracing plies embedded in

the rubber (2). The carcass (3) is composed of a Nylon and polyester framework, in acomplex weave

Conclusion

Research work is going on to increase the

performance of the engines as well as to increase

the dynamic movement of the car.

Although F1 racing engines have lost some of the

attractiveness they used to have when theregulations allowed more freedom, every single

design currently in use is still a highly advanced

piece of engineering that has required lots of time

and thought. An engine is the only power source ofa Formula One car - apart from the KERS systems

in 2009 which are indirectly charged by the power

generated by the engine - and is a structural part

of the chassis.
