Exhaust emissions factors affecting

From the literature, it is clear that the identified emission and fuel consumption models take into account the various factors affecting emissions and fuel consumption rate in automobile. It is further established that these factors have affected vehicular emissions and fuel crmsumption in varying degree. However, efforts on fuel consumption have since crmtinued but still the effects of a leakage on any part of the exhaust system in relation with fuel cmisumption rate have not been investigated. Sequel to this, effects of leaks oti the motor vehicle, specifically on... 

The aromatic hydrocarbon content of motor diesel fuels is a factor which can affect their cetane number and exhaust emissions. The aromatic hydrocarbon content and the naphthalenes content of aviation turbine fuels affects their combustion characteristics and smoke-forming tendencies. These properties represent specifications for aviation turbine fuels (Specification D 1655). 

The different gases emitted in a car exhaust, and their relative concentrations, are closely linked to the efficiency of the combustion process and the health of the engine. For example, wear and tear in the engine, or poor maintenance, may lead to greater emission of CO and hydrocarbons. Another important factor is the air/fuel ratio X of the combustion mixture, which also affects the relative emission of gases (as shown in the LIF spectroscopy imaging of in-cylinder combustion gases) ...
