Abstract
In recent years product improvements to the Series 149 engine have increased air system efficiency and reduced friction horsepower in order to improve the fuel economy and performance of the engine. Recent improvements have been directed at improving the combustion efficiency of the engine by optimizing the combustion process. Increasing the effective power stroke, optimizing the fuel injection characteristics and the liner intake port geometry, and improving the efficiency of the turbocharging and charge air cooling contributed toward significant fuel economy advancements.
This paper will discuss the process of developing these product improvements with proper analytical and statistical tools. Included, also, is a description of the integration of these fuel economy improvements with component improvements into an engine package that provides superior engine performance, fuel economy, durability and 125 horsepower per cylinder for a variety of applications.
