A gasoline motor engine using electronic control system has several sensors and actuators driven by a computer. This paper aims to reveal the role of an engine temperature sensor mounted on a gasoline engine motor. The testing data shows that there is a connectivity between the temperature data obtained from the coolant temperature sensor with the fuel injection time and the exhaust gas emission content.
Electronic control system on a vehicle engine aims to optimize engine performance so that it can save fuel, has bigger power performance and inflicted emission can be pressed. To achieve it, a good synergy between sensor, actuator and its control center are needed.
Sensor roles as a collector of information mounted in the engine. Whereas control center acts as the data receiver which comes from the sensor, and then process it into specified control logic. So that it can produce “value” which then given to actuator. This actuator acts to realize a desired situation based on the amount of “value” resulted from the control center.
When the engine is cooler (lower temperature) especially in the morning, combustion chambers need to be conditioned, therefore the ideal engine heat can be reached sooner. Engine coolant temperature sensor is one of sensors which information becoming the reference as the condition determinant. This conditioning multiplies fuel injection to the combustion chambers.
This study is going to expose the role of engine coolant temperature sensor by analyzing the connectivity between the data of engine coolant temperature, time injection, and exhaust gas emission produced by the engine.
The beginning of fuel injection into the combustion chambers method started from 1970 up to 1980 where the system of fuel injection into the combustion chambers using carburetor system. This system intermingles the air and the fuel inside the carburetor. Along with exhaust gas emission regulation, air intermingling process between air and fuel experiences an increase on its setting pattern. Starting from the year 1970s, air mingling system and fuel establishes one generation of new setting pattern namely Electronic Fuel Injection (EFI) (TTA: 2010).
Electronic Fuel Injection (EFI)
Gasoline injection system with more well-known electronic control is called Electronic Fuel Injection (EFI), fuel injection volume is controlled electronically. The basis of this system has been going through many developments and been implemented by various vehicle brands, not only European made vehicles but also Japanese and American ones. The working of fuel injection injector is set by a Electronic Control Unit (ECU) which is known as ECM (Electronic Control Module) (Daihatsu: 2010).
Engine Coolant Temperature Sensor
Engine coolant temperature (WTS/ECT: engine cooling temperature) is made from thermistor, a resistor variable influenced by temperature. The working performance of ECT and IAT is similar, the difference is only on the sensor function. ECT functions to detect engine coolant temperature as ECM input in order to correct the amount of fuel injection on the injector.
