Sensors for Engine Management

Sensing and forwarding information

Sensors can help cut fuel consumption and harmful emissions. They play a part in boosting engine efficiency and vehicle safety to ensure greater driving comfort and enjoyment.

To fulfill the task of capturing and transmitting data, sensors need to be resistant to temperature, moisture, dirt and chemicals. They also need to function perfectly within electromagnetic fields and in the presence of other sensors, in addition to offering a long service life.

Mass Airflow Sensors

A growing focus on reducing CO2 emissions means that mass airflow sensors are becoming increasingly important in ensuring the optimum air fuel ratio.

Mass airflow sensors are positioned directly after the air filter in the intake manifold and supply information on temperature, humidity and intake air volume. Despite their highly compact construction they feature precision technology to capture information, which – together with other engine data – enables optimum engine management.


Wheel Speed Sensors


The wheel speed signal is crucial for electronic systems like ABS or ASC.


Camshaft Sensors


The camshaft sensor is located in the cylinder head and reads the camshaft sprocket to determine the position of the camshaft.

This information is required for functions such as initiating injection on sequential injection engines, the trigger signal for the magnet valve on pump valve injection systems and for cylinder-specific knock control.


Crankshaft Sensors


The crankshaft sensor supplies information on the crankshaft’s current position, which the engine management system can then use to calculate RPM. These values make it possible to determine the most economical fuel injection and ignition timing for a vehicle.


Knock Sensors


Modern engines which allow high compression ratios have a distinct disadvantage: their design leads to increased knocking, which can damage the engine.

Knock sensors reliably measure the vibration of the engine block that is characteristic of engine knocking. This allows the firing angle and other parameters to be set such that the engine continues to function correctly close to the knock threshold. This not only protects the engine but also reduces fuel consumption. To ensure maximum precision, our knock sensors deploy groundbreaking bandwidth technology.


Pressure Sensors


MAP and T-MAP sensors measure the air pressure in the intake manifold behind the throttle valve to determine the air intake. This information is extremely important for calculating the amount of fuel to be injected to ensure the correct air fuel mix. For this reason, the dynamic measurement capability of these engine management components is crucial in reducing vehicle emissions.

- MAP Pressure Sensor is for turbocharged engines for measuring air pressure behind the turbocharger (measurement range 500–3000 hPa)

- T-MAP Pressure Sensor has an integrated temperature sensor


Oxygen Sensors


The existing portfolio of sensors for engine management is optimally complemented by the inclusion of oxygen sensors, with which the best possible engine power is attained at the lowest possible fuel consumption.

The measurements from a lambda sensor are required to ensure that the catalytic converter converts almost all pollutant exhaust residual that results when a fuel is combusted. Lambda sensors determine the amount of residual oxygen in the exhaust and transmit this value to the engine control, which in turn precisely sets the composition of the mixture using the transmitted values.


GPS Speed Sensor

  • The GPS Speed Sensor uses a GPS receiver to measure true ground speed, then delivers a frequency signal compatible with the radar speed signal input on most controls and monitors.
  • Eliminates problems frequently found with radar speed sensors on wet surfaces, with moving crops, or vehicle vibration.
  • Convenient enclosure mounts inside the cab, only a small patch antenna is mounted outside.
  • Status LEDs show power, GPS lock and speed output conditions.
  • Adapter cables make it compatible with Raven application rate control systems.
  • State of the art GPS engine delivers better performance than many comparable units on the market.
  • Speed range of 0.5-80+ mph (1-130+ km/h). 

Kit includes GPS Speed Sensor, Patch Antenna, and Raven Adapter Cable
