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... 1 Comments
Overview
The idle regulation stepper motor is mounted on the end of the inlet manifold or on the throttle housing; it is controlled electrically by the ECU.
This stepper motor controls an air flow taken in parallel to the throttle with the aim of:
providing an additional air flow (cold starting),
regulating an idle speed as a function of...
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 coolant temperature sensor has two functions:
it informs the ECU of the coolant temperature in the cooling circuit and therefore the temperature of the engine,
it transmits the coolant temperature information to the temperature gauge on the control panel for non multiplexed vehicles.
The ECU uses the coolant temperature...
This sensor is mounted on the exhaust manifold, at the inlet to the catalytic converter and permanently supplies a voltage to the ECU representing the oxygen content of the exhaust gases. It has a green 4 way connector. Two of these four connector pins supply current to the sensor's internal heater. The other two provide a voltage from the sensor...
The ECU is responsible for controlling the "coolant temperature warning" LED when the temperature reaches a critical level (risk of damaging the engine).
To perform this function, a coolant temperature thermocontact switch is used. This is mounted directly into the engine block as it can be more reactive in the event of loss of coolant.
The...
Overview
The inlet air pressure sensor is a new generation sensor and incorporates the inlet air temperature sensor.
The inlet air pressure sensor constantly measures the pressure in the inlet manifold as well as the temperature of the engine inlet air.
It is supplied with +5V by the ECU when the ignition is switched on.
Inlet air...
