Key fact

F1 Engine rules (possible changes
for 2013)
1 1.6 litre, four-cylinder turbos with
energy recovery and fuel restrictions
2 Fuel effi ciency to increase by a target
of 50%
3 Overall power to remain same at
approx 750bhp
4 Plan for advanced ‘compound’
turbos to be introduced in
subsequent years
5 Kinetic energy recovery system
(KERS) to increase from 60kw in
2011 to 120kw in 2013

higher rpm because heat build-up in the bearings is reduced. During each engine
revolution, the piston goes from a zero speed to almost 40 m/s then back to zero.

Maximum piston acceleration occurs at TDC and is in the region of 95 000 m/s ,
or about 10 000 times Earth’s gravity!
The fuel/air mixture is carefully controlled, just like in a standard engine, but in
the case of F1, torque and power are far more important than consumption and
emissions. Inlet and exhaust manifolds and ports are very carefully designed to
achieve optimum gas fl ow, as is the exhaust system, where noise reduction is
not considered.
Overall, the principles of operation are no different to a standard road car
engine’s, except that, keeping within the regulations, the F1 engine is designed
and tuned as near to perfection as possible.
