Engines and KERS

Formula One engines may be no more than 2.4 litres in capacity. They must have 8 cylinders in a 90-degree formation, with two inlet and two exhaust valves per cylinder. They must be normally aspirated, weigh at least 95 kilograms and be rev-limited to 18,000rpm.

The only other permitted power source is a Kinetic Energy Recovery System (KERS), which takes waste energy generated under braking and turns it into additional power. This is then made available to the driver in fixed quantities per lap via a steering wheel-mounted boost button.

Turbochargers, superchargers and devices designed to pre-cool air before it enters the engine's cylinders are not allowed. Nor is the injection of any substance into the cylinders other than air and fuel. Variable-geometry inlet and exhaust systems are also forbidden, as is variable valve timing. Each cylinder may have just one fuel injector and ignition must be by a single spark plug.

The materials used in the manufacture of the engine and its components are strictly controlled by the regulations. The crankcase and cylinder block must be made of cast or wrought aluminium alloys - the use of composite materials is not allowed. The crankshaft and camshafts must be made from an iron-based alloy, pistons from an aluminium alloy and valves from alloys based on iron, nickel, cobalt or titanium.

Formula One cars do not have their own, onboard starting systems. Separate starting devices may be used to start engines in the pits and on the grid. If the engine is fitted with an anti-stall device, this must be set to cut the engine within ten seconds in the event of an accident.
