✦ Synopsis

The effect of ozone addition to the intake air on combustion in compression ignition engines was examined using a Diesel CFR engine. The experimental results show that ozone addition improves the combustion characteristics. Addition of 500 ppm ozone, for example, increases cetane number by 2 to 4 and lowers the compression ratio of the ignition limit by 1 to 2, depending upon the kind of fuel used and the operating conditions. Regarding exhaust emissions, a small decrease in CO, hydrocarbons, and particulates and a small increase in NO x have been observed with ozone addition under the fixed operation condition.

A numerical simulation of a coal-fuelled, reciprocating, internal combustion engine was developed and was used to: (1) investigate the details of the combustion process; (2) identify process controlling phenomena; (3) evaluate the engine performance characteristics with a coal fuel; and (4) establis
