ABSTRACT Camless internal combustion engines offer major improvements over traditional engines in terms of efficiency‚ maximum torque and power‚ pollutant emissions. Electromechanical valve actuators are very promising in this context‚ but still present significant control problems. Low valve seating velocity‚ small transition time for valve opening and closing‚ unavailability of position sensor are the main objectives to be considered in the design of the valve control system. Actuator physical

Koenigsegg’s New Cam-Less Engine February 13‚ 2012 by Matt Jalopnik reports on an upcoming supercar from Swedish boutique automaker Koenigsegg that will feature a twin-turbo V8 engine whole valves are actuated without camshafts. Partnering with Swedish engineering firm Cargine‚ Koenigsegg plans to develop a valvetrain system whereby the valves are operated using pneumatic pressure alone. F1 car engines have used pneumatic valve springs since the Renault turbo engines of the mid-’80s‚ but always

COMBUSTION ENGINES 6.1 Introduction Perhaps the best-known engine in the world is the reciprocating internal combustion (IC) engine. Virtually every person who has driven an automobile or pushed a power lawnmower has used one. By far the most widely used IC engine is the spark-ignition gasoline engine‚ which takes us to school and work and on pleasure jaunts. Although others had made significant contributions‚ Niklaus Otto is generally credited with the invention of the engine and with the
