Abstract

Development of the in-line versions of the 2400G Series of spark ignited, gas-fueled engines has been in process for the last six years. The main objective of this program is to produce a new series of 1200 rpm gas engines having a continuous duty rating of 200 bhp per cylinder. This paper deals with the highlights of the engine development program from the initial concept stage through the operation of prototype engines at customer sites. Development procedures are described that led to substantial advances in performance improvement and exhaust emissions control. A focal point of this work is the combustion analysis, which was conducted through computer simulation and through the operation of a gas-fueled, single-cylinder test facility. This preliminary analysis resulted in the definition of the basic configurations for the prechamber and the main combustion chamber. The applicability of the modeling and the single cylinder test work to the six and eight cylinder engines is evaluated in this paper. Development of appropriate manifolding, turbocharging, and cylinder balance was a critical part of the multicylinder phase of this program. Another key issue was the design and testing of the electronic feedback control system that assures continuous operation at conditions that produce optimized fuel economy and exhaust emissions. The satisfactory operation of the six and eight cylinder 2400G prototype engines in the field is based on the foundation of the developmental work described in this paper.
