In the history of automotive industry, many extensive efforts have been done to design systems that make
it possible to reduce emission and increase the efficiency of the vehicles. Since the emission of pollutants is
directly proportional with the fuel consumption, therefore any effort to achieve the optimum fuel consumption
leads to reduced pollutants. One of the most effective systems available for reduction of fuel consumption
is continuously variable transmission system (CVT) which has been developed considerably during the
last decade. Presently, an important issue that the automotive manufacturers in Iran and all over the world
face with it is the feasibility of replacing the traditional manual transmission with CVT systems from the
viewpoint of the fuel consumption. Here, the fuel consumption of a vehicle with a manual transmission is
compared with the same one equipped with a chain drive CVT system. By using the Genetic Algorithm, the
fuel consumption of the vehicle with the mentioned CVT system, which is controlled automatically by ECU,
is optimized. The results concerning the comparison between the two mentioned systems indicate that even
if a skilled driver shifts the gears of the vehicle with the traditional transmission manually in a way that the
optimum fuel consumption is reached, the fuel consumption in the vehicle equipped with CVT transmission
will be considerably less than that with manual gearbox transmission.
