A new family of diesel engines was required to power a new mid-sized tractor product line being developed by Ford New Holland. This new family of engines, which are now known as the GENESIS engine family, figure 1, went into production in November 1991.
A strategy of large displacement, low RPM, naturally aspirated diesel engines was used to achieve program objectives. The engines are four and six cylinder in-line, direct injected with displacements of 1.1 liter/cyl and 1.25 liter/cyl. Significant improvements were achieved in all aspects of performance, durability, reliability and cost. Simultaneous engineering methodologies were developed early and were key to meeting program objectives.
In addition to describing the design detail and performance aspects of the GENESIS engine this paper describes in some detail the simultaneous engineering approach used throughout the development and launch process.
