The use of internal combustion engines in underground mining operations presents several interesting problems involving safety and health. This study deals with the nature of the exhaust gases from Diesel motors. These gases may be hot enough to ignite inflammable atmospheres in mines and contain definitely toxic constituents. Variations in use result in changes in the nature of the exhaust gases, but even under optimum conditions of speed, power output and fuel-air ratio, sufficient quantities of carbon monoxide, carbon dioxide, the oxides of nitrogen and aldehydes are produced to make ventilation necessary.
