Abstract
The exhaust emission characteristics of 4-stroke, direct-injection diesel engines, naturally aspirated and turbocharged, have been investigated. Data on the emissions of carbon monoxide, oxides of nitrogen, and unburned hydrocarbons are presented.
It is shown that concentrations of these emissions increase with increasing fuel-air ratio. Turbocharged engines, by virtue of running at generally lower fuel-air ratio, tend to produce lower concentrations at equivalent loads and speeds.
