Specification<\/strong>
\nOnly 4-stroke engines with reciprocating pistons are permitted.
\nEngine capacity must not exceed 2400 cc.
\nCrankshaft rotational speed must not exceed 18,000rpm.
\nSupercharging is forbidden.
\nAll engines must have 8 cylinders arranged in a 90\u00ba \u201cV\u201d configuration and the normal section of each cylinder must be circular.
\nEngines must have two inlet and two exhaust valves per cylinder.
\nOnly reciprocating poppet valves are permitted.
\nThe sealing interface between the moving valve component and the stationary engine component must be circular.<\/p>\n

Dimensions, weight and centre of gravity <\/strong>
\nCylinder bore diameter may not exceed 98mm.
\nCylinder spacing must be fixed at 106.5mm (+\/- 0.2mm).
\nThe crankshaft centreline must not be less than 58mm above the reference plane.
\nThe overall weight of the engine must be a minimum of 95kg.
\nThe centre of gravity of the engine may not lie less than 165mm above the reference plane.
\nThe 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.
\nVariable geometry systems are not permitted<\/p>\n

Materials<\/strong>
\nMagnesium based alloys, Metal Matrix Composites (MMC\u2019s) and Intermetallic materials may not be used anywhere in an engine
\nCoatings 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.
\nPistons must be manufactured from an aluminium alloy which is either Al-Si ; Al-Cu ; Al-Mg or Al-Zn based.
\nPiston pins, crankshafts and camshafts must be manufactured from an iron based alloy and must be machined from a single piece of material.
\nA supplementary device temporarily connected to the car may be used to start the engine both on the grid and in the pits.<\/p>\n","protected":false},"excerpt":{"rendered":"
