Camless Engine: An Approach

Abstract

An engine with an electro hydraulic camless valve train, capable of total valve motion control, has many advantages other than the conventional engine. The system uses neither cam nor springs, which reduces the engine height and weight electromagnetic forces both open and closes the valves. During valve acceleration, potential energy of the spring is converted into kinetic energy due to electromagnetic force of the valve. During deceleration, the energy of valve motion is returned to the initial position. The System offers a constantly variable and independent control of practically all parameters of valve motion. This allows optimization of valve events for each operating condition without any cooperation. The major objective of this paper is to design and manufacture an internal combustion engine that proved the concept of a camless engine. More specifically, it is an electro/hydraulic internal combustion engine capable of producing engine valve displacement at typical automotive demands.
