Electronic Throttle Control for Light Diesel and Gasoline Engines 922469

It is widely recognised that medium and heavy duty diesel engines are increasingly utilising electronic control to optimise injection timing, pressures and governing to ensure that maximum performance capability is realised and that adherence to latest and future legal emissions are met.
The addition of electronic diesel control on a vehicle also provides the manufacturer with the opportunity to increase the user and operational features list by software development of existing controls.
This increase in features has been well received by the end user and there is now an expectance that top range vehicles will include cruise control, speed limiting, traction control and other features as standard when these vehicles are equipped with electronically controlled engines.
On medium and light application engines, electronic diesel control may not be necessary to meet emissions and there are indications (particularly in Europe) that these light to medium engines will not include electronic diesel control or governing until well into the year 2000.
It is therefore apparent that users of a wide range of vehicles will be accepting and utilising features on heavy vehicles that are not yet available on the medium to light vehicle ranges.
The application of an electronic throttle control system such as the one described in this paper will provide many of the safety, economy and user features of electronic engine control in an adaptable form for the vehicle manufacturers at a lower cost than a full engine management system.
