Perkins has introduced the 4006 electronic engine. The new six-cylinder, 23 litre engine is rated at 750 kVA prime. It offers power density, simplified service requirements, world-class load acceptance and the ability to operate over a broad range of ambient temperatures and altitudes. The valves use new alloys in optimised designs and geometries to improve performance and extend their service life, resulting in a cylinder head top end overhaul period of 15,000 hours. It also helps reduce specific fuel consumption of up to 7 per cent.
