HUCO Ignition Modules
Ignition Modules are an integral part of the engine management system. This consists of at minimum, the Hall effect sensor or impulse generators, the ignition module, the ignition coil and spark plugs.
When there is a faulty signal from the ignition module, you can experience misfires, stuttering of the engine or a total failure. In these cases, they must be replaced against a new part. A repair is usually not possible because the parts themselves are too complex. Ignition Modules can be divided into two sub-groups Amplifier and Pick-up/Hall systems.
Amplifiers
The amplifier consists of different internal power transistors switching the primary current feeding the ignition coil. Transistors limit both the primary current as well as the primary voltage in order to avoid defects of the ignition system.
Amplifiers are either an integral part of the ECU or alternatively, mounted within the engine compartment (mostly in combination with an ignition coil). In this location, the module must withstand enormous variations in temperature, vibration and humidity, with under hood temperatures easily reaching 50 Degrees Centigrade.
Coupled with the heat naturally generated by the module itself, it must withstand this hostile environment and still perform to specifications.The resulting heat has to be carried off quickly by cooling sheets.
HUCO Fuel pump relays
Fuel pump relays are compulsory safety units for any vehicle. The fuel pump of the vehicle is switched on via the relay when starting the car’s engine.
The electronic circuit of the relay checks if the motor is running. In case the motor is suddenly switched off, e.g. in case of an accident, the relay will cut the power supply to the fuel pump within 1-2 seconds.
HÜCO Glow plug relays
Glow plug relays are used in diesel driven passenger cars. A glow plug relay switches on the necessary electric current of the glow plugs prior to starting the engine.
Various pre-heating control times are required according to the type of vehicle. Pre-heating times are dependent of outside air temperature and motor temperature. Glow plug relays monitor these factors and will control the pre-heating time of the glow plugs in accordance of the temperatures.
Newer vehicle models will also switch on the glow plugs in certain situations during operation of the car.
Air Flow Meters
An important criteria for the development of passenger cars is the requirement to meet legal emissions and optimize overall engine performance and fuel economy. To achieve this task it is necessary to determine the exact relation of air mass to fuel which is accomplished by the air flow meter.
The Air Flow Meter is used to measure the mass flow rate of air entering the engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature, altitude and the use of forced induction, which means Air Flow Meters are more appropriate than volumetric flow sensors for determining the quantity of intake air in each piston stroke.
Structure
The actual sensor is integrated in the flow channel of the plug in sensor. These plug in sensors are suitable for the installation in air cleaners and in so-called measuring tubes, which are to be found in passenger cars.
An electronic measuring system converts the sensor data into appropriate measuring data for the engine management/fuel injection system.
Function
The system is based on an indirect measurement of the air flow. The sensor element is heated by an electric circuit to a specified value. As air passes over the element the sensor measures the drop in temperature. The measured temperature of the sensor element is reduced as the air flow is increased, and measured temperature increases as the air flow is decreased. The sensors integrated electronic evaluates this data resulting in an exact determination of the air flow.
