1. Oxygen Sensor

    ▶ Function

       - This sensor generates 0 or 1V according to the oxygen concentration in engine

         exhaust gas and has been widely used as the key component of the exhaust gas

         purification system contolling the A/F ratio. This high performance and highly

         reliable sensor contributes to clean air under the current strict emission

         regulatations      

    ▶ Chracteristic

       - Compact design allows a more flexible installation

       - High Tolerance for chemical deposits and long life

       - Better low temperance activity

       * Excellent sealing performance to prevent gasoline and water

       * Ingress    

2. Map Sensor

    ▶ Function

       - Manifol Absolute Pressure Sensor measures the pressure of intake manifold for

         calculating indirectly the intake air flow quantity to the engine and transmit the

         signal to engine contorl unit

    ▶ Structure

       - The piezo-resistive pressure sensor element and a suitable circuit for signal

         amplification and temperature compensation are intergrated on a silicon chip

       - When the intake manifold pressure is led up by a pressure nozzle to the

          diaphragm, the resistor valuepositioned on the diaphragm surface is changed

          with proportion to the stress variation and it is converted to the electrical signal

   ▶ Feature

       - Silicon diaphragm fabricated by Micro Electro Mechanical System

       - One chip design pressure sensor combined silicon diaphragm with signal

         conditioning circuit

       - Good endurance

       - Fast response, High senstivity, Good hysteresis

3. Oil Sensor

    ▶ Function

       - The Temperature sensor has a NTC (Negative Temperature Coefficient) sensing

         element, whcih send oil, air, coolant, fuel temperature information to ECU

         (Engine Control Unit) as mounting.

       - Temperature information is application data for controlling engine and

         transmission       

    ▶ Chracteristic

       - Suitable appearance and inside structure composition

       - Connection system

       - Wide operating range on temperature

       - Suitable mounting and sealing method

4. Water Temperature

    ▶ Function

       - This part senses the cooling water temperature in the engine block and

         generates two types of corresponding electrical signal, one of which is

         transmitted to ECU (Engine Control Unit) as voltage and the other to

         the thermometer on the instrument panel          

    ▶ Characteristic

       - Intergrated part of Water Temp. Sensor and Temp.Sender unit

       - NTC (Negative Temperature Coefficient) Thermometer

       - Sensitivity (response) : Max 15 sec.

       - Applicable temperature range : -40 ℃ ~ +130 ℃
