Cooling System Overview The purpose of the cooling system is to draw the heat of the engine away and to either heat the inside of the car via the heater matrix or to cool it. Following a cold start the coolant circulates around the engine block and cylinder head spreading heat around the engine. The thermostat is closed preventing this hot...

Overview The catalytic converter is designed to reduce, by catalysis, unburned pollutant gases at the exhaust: • CO: carbon monoxide • HC: hydrocarbons • NOx: nitrogen oxide Catalysis is a phenomenon which, by using a catalyst, encourages chemical reactions without the catalyst itself being involved in the chemical reaction. As it deals...

The carbon canister contains an active carbon filter. It is located between the fuel tank and the canister bleed electrovalve and is located in the Saxo driver's side wing (RHD). The fuel vapours in the fuel tank are absorbed by the active carbon. This aim of this function is to prevent: • the pressure rising in the fuel tank, • vapours...

The throttle potentiometer is located on the throttle housing. Supplied with +5 V by the ECU, this potentiometer transmits a variable voltage to the ECU which is a function of the position of the throttle (driver's wishes). This information is used for recognising no load and full load positions and transitories for acceleration,...

The engine speed sensor consists of a magnetic core and a winding. It is positioned opposite a ring on the flywheel with 60 teeth, 2 of which have been removed in order to determine the TDC (top dead centre) position. When the teeth of the flywheel pass in front of the sensor, a variation in magnetic field is created. This variation...
