Techniques for Higher Power Density and Lower Exhaust Emissions on Non-Road In-Direct Injection Diesel Engines

In recent years, exhaust emissions regulations is increasingly enhanced on the non-road diesel engines, which are mainly used for agriculture, industrial and construction applications in world-wide area, in order to prevent air pollution on the earth. On the other hand, customers demand higher power in a tight packaging constraint to be competitive on the product that the engine is installed. We developed the all-new 1.3 liter non-road In-Direct Injection (IDI) diesel engine, which realized to balance the strict exhaust emissions regulations and user needs such as compact and higher power. This paper reviews the technologies to achieve the targets, higher power density and lower exhaust emissions on the newly-developed small IDI diesel engines.
