Easy to Build of CDI – We know, the principle advantage of a CDI (Capacitor Discharge Ignition) System is the ability to present a superior spark to the air/fuel mixture inside the combustion chamber, thus maximizing burn efficiency. The easiest way to build CDI, we must understand to know Basic Ignition System. Look This below Schematic Diagram of CDI System.
Water temperature sensor functions to detect changes in engine coolant temperature. These sensors connect with a thermistor in a resistance value that changes according to changes in engine coolant temperature. Thermistor has a characteristic resistance values are greater if the low water temperatures and has a small resistance value when the high cooling water / heat. Read the rest of this entry »
When the ignition key in position “ON” the main relay will supply power to the engine control unit (ECU). These relays in the relay box in engine cabin. Read the rest of this entry »
Vehicle Speed Sensor in the speedometer. construction of this sensor consists of a rotary shaped, rotary magnet having the same rotational speed on the speedometer cable on the reed switch position “ON / OFF”, then the vehicle speed input is sent to a computer. There are four pulses generated at the speedometer cable. Read the rest of this entry »
Air temperature sensor detects the temperature of air entering the suction by the engine. These sensors connect with a thermistor in the sensor has characteristics such as engine cooling water temperature. Air density depends on the temperature, so the electronic control unit (ECU) must be able to compensate for the ratio of air and fuel based on the signal sent from the air intake temperature sensors.

Electronic Instrument Clusters – The major difference betwen an electronic instrument cluster and the conventional analog or gauge, type is the way in which the information is displayed. Essentially the same types of sending units or sensor are used in both systems. Electronic instrument computer sometimes called a body computer to process input information from sensor and to operate electronic display. Read the rest of this entry »
Magnetic sensors are commonly used in automotive circuits to signal the position of a component. There are two principal types of magnetic sensors:magnetic pickups and hall-effect switches.
A magnetic pickup consist of a coil winding and a permanent magnet core. The permanent magnet creates a magnet core. Read the rest of this entry »
