Results and analyses of the smoke from compression ignition CI engines (diesel)

The aim of this examination is to improve the knowledge about the actual ecological condition which is a result of the gas and particles emission from the diesel engines. The mechanism of the production of combustion products including the particles in the combustion chamber has been studied, as well as the options for reduction of the emission. Measurements of the smoke emission from the vehicles in Skopje have been made and the results are given, including their analyses. The conclusion from the analyses is that it is necessary to improve the conditions for normal use of the diesel engine vehicles, as well as to engage new vehicles which cause less damage for the environment (Author)
