The Electronic Governing of Diesel Engines for the Agricultural Industry 860146

This paper explores the governor characteristics which can be provided for engines in tractors and other off highway applications. These do not have to meet stringent emission regulations, and therefore do not need precise control of timing and maximum fuel.
The paper describes a simple electronic governor concept which has two regions, one for driving on the road and the other giving close, all speed regulation for off highway and Power Take Off operations.
Such an approach offers better governing, driveability and communication with other vehicle systems. In the field this would give a more uniform rate of working and spreading of fertilizers etc, less tendency to stall and result in a more economic operation.
This system replaces the standard mechanical governor, but otherwise the pump remains unaltered, so the engine manufacturer can fit either the mechanical or electronic governor as required without additional engine application work or change to its power rating.
This technique could be used on industrial engines and generator sets.
