The industrial diesel engines are used in many types of applications, and the market has strong needs for low-cost, compact, high-output and high-reliability. In addition, exhaust emissions regulations for industrial diesel engines are being strengthened and all engines must conform to all of them. Therefore, low-emission is an essential condition.
This paper describes attempt of optimizing the shapes of an inlet port and a combustion chamber to achieve high power and low emission using Computational Fluid Dynamics (CFD). In addition, a new water passage structure was developed against increasing thermal load caused by high outputs and improved reliability and durability. High-stiffness ladder-frame was employed at crankshaft supports to achieve low noise and low vibration, and gear train was placed on the flywheel side to reduce gear noise. As a result, the industrial direct injection diesel engine featuring high-output, compact size, and favorable noise and vibration characteristics was developed.
