Abstract
The internal combustion engine (ICE) finds its place in the market with latest design modifications in various components to improve efficiency, economy and overall performance. However, one component has remained unchanged in the internal combustion engine development i.e., the camshaft, has been the primary means of controlling the valve actuation and timing, and therefore, influencing the overall performance of the vehicle. Camless technology is capturing the future of internal combustion engines. It has been known to man that if valves could be controlled independently in an Internal Combustion Engine then there would be benefits like increased power, reduced emissions and increased fuel economy. In the camless technology valve motion is operated by valve actuators of electro-mechanical and electro-hydraulic type. In this paper we compare camless valve operation with conventional valve operation and we deal with the valve actuating mechanisms of camless engine by considering the electromechanical and electrohydraulic actuators as the important types of actuating valves in camless engines.
Highlights
Rudolf Diesel - an outstanding engineer at the Technical University of Munich in Germany invented a type of internal combustion engine and a patent granted to him in 1892 protects the copyright of an engine called diesel[1]
The electromechanical actuator acts to increase the overall efficiency of the engine by eliminating friction losses of the camshaft components, reducing the engine weight and reducing the output power of the crankshaft. to hybridize gas distribution devices
Designed in accordance with the opening rate of the valve at the minimum rotation of the engine, the electric actuator opening of the opening and opening of the opening at the same time is the same as the unexpected mode of exploitation of the engine. Due to this improvement in speed, it leads to greater flexibility in the situation with muffins, allowing for higher moomen levels, reduced exhaust emissions, and improved fuel economy
Summary
Rudolf Diesel - an outstanding engineer at the Technical University of Munich in Germany invented a type of internal combustion engine and a patent granted to him in 1892 protects the copyright of an engine called diesel[1]. These forces are constant throughout the armature's displacement because the size of the gap does not change Most of these systems use electromagnetism or magnets to create the attraction or push of the main actuators made of iron or ferromagnetic core. Changing the current flowing through the armature coil and or changing the intensity of the electromagnetic field can control the opening and closing speed of the pan. This method can be used to slow down the movement of the valve, reducing the opening and closing speed of the valve as well as reducing the noise[22].
