Abstract
Recent global environmental problems which have come to light must be solved for ensuring the survival of the human race. And it is of the utmost importance that we give to our descendants a world full of nature and beauty.
In the past years Mitsubishi Motors Corporation (MMC) has long been positive in research and the development activities so as to satisfy the demands for low emission and good fuel economy vehicles. (1)
As one example of our research efforts, the technology that will meet the US '94 HDDE exhaust emission regulations, which is one of the most stringent regulations in the world, is described in this paper.
The exhaust emissions were reduced by improvement of combustion, using the pre-stroke control type fuel injection pump and optimizing the combustion chamber shape.
Efforts were also made to improve the oil consumption, in order to reduce PM (Particulate Matter) emission.
And the target could be achieved with the oxidation catalyst, which was effective for reduction of the SOF (Soluble Organic Fractions) in PM.
In addition to exhaust emission reduction combustion noise reduction using the 2-spring fuel injection nozzles, is mentioned here.
