AUTOMATION OF SOLENOID ACTUATOR IN A CAM-LESS ENGINE

Abstract

“Any technology becomes outdated and obsolete the day it is developed.” The modern internal combustion engine with its many modifications and changes is still using a component which has been present but not necessary since its invention back in the year of 1859. The camshaft is used to control the opening of valves in an internal combustion engine.
Our team observed that the camshaft required to make peak power in any vehicle is entirely dependent upon the speed of the engine, which essentially means that the engine’s demand and output differs on different speeds thus limiting its overall performance.
Our team has tried to completely change the approach taken to counter this problem, by removing the cam entirely from the engine and using sensors and solenoid actuators to control the valve opening and closing. In this paper we are trying to achieve automation of solenoid in Cam-less Engine with the help of Arduino Uno Chip set.
The team has tried to develop an entire independent design of the system using the already existing technologies such as commonly used push pull solenoid and controlling its actuation in a closed loop by the help of the Arduino chip. This is done to achieve greater efficiencies and better performance during the operation of the engine at low and high speeds.
One of our goal for this project is to eliminate mechanical linkages as they are one of the major causes of energy loss in any mechanical system. Being able to remove losses is one of the most important aspect of developing better and more efficient systems better capable of handling the growing demand of both the environment and the consumer market.
