This Paper gives an overview about the latest camless engine designed using laser LDR circuit. Engines that are being used in today’s automobile consist of a cam shaft which lifts up and closes the fuel inlet and outlet valves of the engine. Due to the inefficiency of the cam shaft to open up and close the engine fuel valves on time, it does not follow the ideal valve timing diagram and gives less output power and fuel economy then the calculated one. Lack of efficiency to open up and close the engine valves on time also result in presence of hydrocarbon and unburnt fumes in the engine exhaust. In order to overcome all these inefficiencies, a camless engine is developed in which the valves of the engine are actuated hydraulically with the help of a laser LDR Circuit. In the proposed system a laser LDR circuit is fitted over the crank shaft of the engine which senses the exact time of opening and closing of engine valve. The developed engine gives better power output and fuel economy by making the engine to follow the ideal valve timing diagram and hence eliminates all the inefficiencies of the engine by making today’s automotive engines more environment friendly by producing less hydrocarbons and unburnt fumes. The newly developed camless engine can be used in any type of automobile which uses IC engine as a power unit.
