Exhaust emission characteristics of 4-stroke, direct-injection diesel engines, naturally aspirated and turbo-charged, have been investigated at Cummins Engine Co, Inc; data on 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.
