Belt Slackness Detection for the Automobile System

General opinion for the cause of overheating in the engine is scarcity of water in the radiator which causes the engine to seize. Normally refilling the radiators would solve the problem but we have several proven cases where engines still seize due to loosening of belts. Though the current technology allows detection of engine temperature, there is no technique to detect this fault and to alert the driver. Our paper advocates a feasible solution for the above mentioned problem. A simple circuit with a potentiometer and LM3914 are employed to indicate any deviations in the tension or slackness in the belt. This also helps in preventing other serious consequences that can occur due to improper functioning of the timing belt which is used to drive the cam shaft in an overhead camshaft.
