F1 engines – FIA technical regulations

Here is an interesting extract from the FIA regulations for the engine, just thought it would be useful in case you wanted to design your own… Winking smile

Specification
Only 4-stroke engines with reciprocating pistons are permitted.
Engine capacity must not exceed 2400 cc.
Crankshaft rotational speed must not exceed 18,000rpm.
Supercharging is forbidden.
All engines must have 8 cylinders arranged in a 90º “V” configuration and the normal section of each cylinder must be circular.
Engines must have two inlet and two exhaust valves per cylinder.
Only reciprocating poppet valves are permitted.
The sealing interface between the moving valve component and the stationary engine component must be circular.

Dimensions, weight and centre of gravity
Cylinder bore diameter may not exceed 98mm.
Cylinder spacing must be fixed at 106.5mm (+/- 0.2mm).
The crankshaft centreline must not be less than 58mm above the reference plane.
The overall weight of the engine must be a minimum of 95kg.
The centre of gravity of the engine may not lie less than 165mm above the reference plane.
The longitudinal and lateral position of the centre of gravity of the engine must fall within a region that is the geometric centre of the engine, +/- 50mm. The geometric centre of the engine in a lateral sense will be considered to lie on the centre of the crankshaft and at the mid point between the centres of the forward and rear most cylinder bores longitudinally.
Variable geometry systems are not permitted

Materials
Magnesium based alloys, Metal Matrix Composites (MMC’s) and Intermetallic materials may not be used anywhere in an engine
Coatings are free provided the total coating thickness does not exceed 25% of the section thickness of the underlying base material in all axes. In all cases the relevant coating must not exceed 0.8mm.
Pistons must be manufactured from an aluminium alloy which is either Al-Si ; Al-Cu ; Al-Mg or Al-Zn based.
Piston pins, crankshafts and camshafts must be manufactured from an iron based alloy and must be machined from a single piece of material.
A supplementary device temporarily connected to the car may be used to start the engine both on the grid and in the pits.
