The main kinds of sensors applied to the ignition time control system are as follows: (1) the engine speed sensor. Test the engine speed. The faster the speed, the more early the ignition time.
(2) air flow sensor. The amount of air that is inhaled is measured and used to calculate the load parameters to correct or delay the ignition time.
(3) water temperature sensor. Test the temperature of the engine coolant.
(4) the intake temperature sensor. Check the temperature of the air. The ignition time should be delayed when the water temperature and the intake temperature are high.
(5) the crankshaft angle sensor. The angle of the crankshaft is detected, and the time and order of the ignition are determined.
(6) the intake pressure sensor. Test the amount of air that sucks, and calculate the load.
(7) the throttle position sensor. Test the opening and idle state of the throttle.
(8) speed sensor. Check the speed of the vehicle.
(9) deflagration sensor. Monitor whether the engine is deflagration. When serious deflagration is produced, the ignition time should be delayed.
(10) oxygen sensor. Monitor the oxygen content in the exhaust.
