Design of Innovative Engine Valve: Background and Need

This is part one of the paper on conceptual design of an engine valve. This paper describes the background and the need of an engine valve for an internal combustion engine. The present state of the engine valve technology and the innovations incorporated in its design has been described. The paper presents the conceptualization of an innovative valve train aiming at lesser number of components, reduction in friction and wear, proper sealing, and trimming down pumping losses. The need of these objectives have been identified and established. The next part of this paper describes the various geometric designs of valve trains that have been conceptualized and compared by using the Magnetorheological Fluid (MRF) and electromagnets.
