ACSES: Automobile Coolant Sensor System / Nadthawuth Ketnukkunn Su Piang ... [et al.]

ACSES is a system to prevent the occurrence of engine overheating. ACSES warn drivers before the engine overheat, to prevent drivers from going further with a faulty cooling system that disturb the performance of the engine. We install a fluid level detector in the vehicle coolant tank. Coolant leakage is caused by a loose or leaked hose. The fluid level detector consists of two main parts. A reed switch and a magnetic floater. When coolant level is high, the magnetic floater is far from the reed switch, causing it to deactivate the circuit and vice versa. The circuit will be activated when the magnetic floater reaches a certain distance from the reed switch. We built a prototype to stimulate the car’s cooling system. Our results showed that the fluid level sensors manage to give out an alarm before the coolant runs out completely, the system succeed to detect the decreasing of coolant. So, we can rely on ACSES as an early detection system to detect a faulty cooling system. ACSES can prevent the overheating of the engine that can cause damage and costly to repair. Installing of ACSES can surely maintain the condition of car engine as the original.
