Abstract: While electronic controls on spark ignited automotive engines are today commonplace and state of the art, the application of such controls to diesel engines is lagging considerably behind, although most experts by now agree that the diesel engine will benefit at least as much as the gasoline engine from such controls. The main roadblock to the introduction of such controls is the lack of reliable and functionally sound sensors. This paper gives for the first time a comprehensive description of a new timing sensor, the only needle lift sensor on the market which automatically adjusts itself to its environment, processes the needle lift signal internally, and emits a highly accurate timing as well as duration of injection signal for direct use in electronic diesel control and display systems.

Keywords: injection sensors; electronic controls; diesel engines; needle lift sensors; timing sensors; smart sensors.
