Diesel engine emissions

Diesel engine, like other internal combustion engines, converts chemical energy contained in the fuel into mechanical power. Diesel fuel is a mixture of hydrocarbons which—during an ideal combustion process—would produce only carbon dioxide (CO2) and water vapor (H2O). Indeed, diesel exhaust gases are primarily composed of CO2, H2O and the unused portion of engine charge air. The concentrations depend on the engine load, with the content of CO2 and H2O increasing and that of O2… more
