Camshafts normally have one lobe per valve, with a fixed valve duration and lift.The camshaft rotates at half the rate of the crankshaft.One person in the latter category is Christian von Koenigsegg, the rather brilliant inventor behind the Swedish supercar skunkworks that bears his name.Anyone with a basic understanding of how engines work is bound to be impressed by von Koenigsegg's latest, a camshaft-free design.The engine's Swedish designer Free Valve claims that the 1.6-litre (98 cu in) turbocharged engine will produce 170 k W (230 hp) and 320 N⋅m (240 lb⋅ft) of torque.They also claim that, compared to a similar traditional engine, it offers a 50% reduction in size (including a 50 mm (2.0 in) lower height), 30% reduction in weight, 30% improvement in power and torque, 30% improvement in fuel economy, and a 50% reduction in emissions.

Some manufacturers use systems with more than one cam lobe, but this is still a compromise as only a few profiles can be in operation at once.Additionally, because there is no chain connection between the crank shaft and the camshaft, the engine is lighter with fewer points of failure.The absence of a camshaft also means that the parasitic load on the engine is lower, which is particularly useful in large marine engines, as it can equate to a large amount of power savings.Direction changing on older B&W MC engines was engaged by changing the direction of the cam roller, whereas with the new camless engine, it is controlled by a computer.This eliminates the risk of mechanical failures that could damage the engine if there was a malfunction while changing directions.
