Today's passenger cars provide a very long service interval. Because of this, the monitoring of the oil condition is becoming more important. It is necessary to monitor the oil condition to prevent engine failures as a result of extreme driving conditions, such as when one makes many short trips over a long period. This task can only be reliably realized by means of a sensor located in the difficult environment of the engine oil. As a significant supplier of oil level sensors, Hella developed, in cooperation with its partners, a low cost microsensor. Based on simulation results, a sensor design was developed and later fabricated by employing standard CMOScompatible materials and processes. The microsensor allows for the measurement of various electrical and physical parameters. This sensor can provide a significant contribution to the reduction of the running costs of the car. It can also protect the environment through extended oil change intervals by considering driving behaviour. Additionally, damage caused by oil deterioration in sophisticated engines can be prevented.
