A Study of Exhaust Emission Characteristics Depending On Fuel Contents of LPG Vehicles.
Diesel engine vehicles emitting the particulate matters (PM) and Nitrogen Oxides (NOx) into the air take 29% of the whole car population in Korea, which is higher than that of the advanced countries.
Therefore, the government is encouraging to use LPG fueled vehicles in place of diesel fueled vehicles, and the number of LPG vehicles is increasing.
The LPG having less carbons in molecular structure compared with gasoline is evaluated as clean fuel as it creates less hydrocarbon (HC) and carbon dioxide (CO2), and less PM and NOx.
However, the current fuel supply system of an LPG engine supplying the fuel into an engine is of a mixer type by which fuel is supplied in a gas state, and the air-fuel ratio is not controlled as precise as the liquid injection type used in a gasoline engine, and it results in more emissions as the engine ages due to varying air-fuel ratio.
Therefore, it is inevitable to develop a technology enabling a liquid injection of LPG to achieve low emission of LPG vehicles. LPG is a mixture of butane and propane which have different number of carbon and hydrogen, and it causes difficulty in starting a cold engine in winter affecting emissions as well.
Therefore, by changing the contents butane and propane of LPG and by measuring and analyzing the emission in different driving modes, the study is focused on finding a fuel suitable for an LPLi system to be developed in the future.
As a result, it was learned that the emission is dependent on the fuel content, i.e. higher rate of propane causes less emission in general.
