Mohamad Abdul Rois Introduction Three EFI systems work on the 2011 Daihatsu Xenia Type Xi car.
These systems are the air induction system, the fuel system, and the electronic control system .
The air induction system applies technological developments to measure the air entering the combustion chamber.
Components in the air induction system include air filter.
Mass Air Flow Sensor (MAF Senso.
or Manifold Absolute Pressure Sensor (MAP Senso.
, throttle valve, air intake chamber, intake manifold runner, throttle position sensor, and intake valve .
The 2011 Daihatsu Xenia Type Xi air induction system consists of several components:
MAP sensor.
IAT sensor, and ISC.
The MAP Sensor is an air induction system sensor that functions to measure the air pressure entering the intake manifold, then converted into an electrical signal to be sent to the Electric Control Unit (ECU) .
The MAP sensor is a component that affects the amount of fuel injected into the combustion chamber because the MAP sensor can measure the air entering the intake manifold .
Intake Air Temperature (IAT) is a sensor that functions to detect the density of air entering the intake manifold based on air temperature .
The Intake Air Temperature sensor is vital in measuring temperature changes in the intake manifold .
If the IAT sensor is damaged, the engine performance will not be optimal.
Damage, if the IAT sensor is damaged, includes engine down acceleration, difficulty starting when the engine is cold, wasteful fuel, and unstable idle rotation .
Idle Speed Control (ISC) is a type of actuator in the EFI system that regulates the air entering the intake manifold when the throttle valve position is closed and the engine is idle .
ISC is an electronic regulator on the car to determine engine idle.
So that if the component is damaged, it will cause the engine rotation to be unstable.
Based on observations and direct observations on the 2011 Daihatsu Xenia Type Xi car at the Workshop of the Piksi Ganesha Indonesia Polytechnic, it was found that there were problems with the engine running unstable and the exhaust gas smelling of gasoline that stings.
Based on these problems, engine rotation and exhaust gas research will be carried out.
The induction system on the 2011 Daihatsu Xenia Type Xi was chosen as research material because each component of the air induction system is related to engine speed and exhaust gases.
