Summary:

Recently in North America, natural gas such as shale gas has gained much attention, and industrial SI engines are expected to fit in various fuels such as gasoline, LPG, and natural gas. Also tightened exhaust emissions regulations require industrial SI engines to adopt feedback fuel injection systems with three way catalysts. In response to these requirements of customers, we have developed a bi-fuel engine model which can be operated on any of gasoline, LPG, and natural gas. In this paper, approaches and technologies used for the development of the model are explained. On the gasoline version of the model, the locations of fuel injectors and the design of the inlet manifold with a surge tank were optimized by using Computational Fluid Dynamics (CFD). And we sought the optimum arrangement of an inlet manifold, a fuel delivery pipe, and plug-on type ignition coils. In addition, the variants which can be operated on LPG or natural gas are equipped with the gas delivery devices that are arranged within a small space. By these approaches, all of these variants have the profile which is interchangeable with the original diesel fueled model. The exhaust emission performance to satisfy the transient mode regulations and the optional small catalytic muffler which can be used in any desired orientations expand the ability of the model to fit within various OEM applications
