The use of fossil based fuels or their synthetic derivatives in energy consumption constitutes an

important part of energy consumption. The use of fossil-based fuels as the main energy source in internal

combustion engines has made motor vehicles one of the main responsible for the formation of air

pollution. In addition, exhaust emissions that are released after combustion in motor vehicles have

immediate and direct-acting toxic properties as well as polluting effects. Therefore, researches on

reducing the damages of motor vehicle emissions and control systems developed against them are

increasingly continuing. In this study, predictions that may occur until 2040 are estimated considering

the increase statistics in the num ber of automobiles in Turkey for the 2004-2019 year. In consideration

of these data, fuel saving and the amount of reduction in CO2 emission from automobiles in 20% of

these automobiles, to be achieved in case one or more of the cylinders are temporarily deactivated, has

been calculated.In these calculations, the annual average mileage of the automobiles was taken as basis

by using TUIK data, and the amount of fuel consumed by automobiles and the amount of emitted CO2

emission were calculated.According to the estimation results, the total number of automobiles in 2020,

2030 and 2040 will be approximately 14,313,428, 25,441,821 and 40,595,492 million respectively, and

the fuel consumption values have been obtained as 13.7, 24.5 and 38.8 million m3 respectively.

Accordingly, the total carbon dioxide (CO2) exhaust emission amounts are estimated as approximately

30.1, 55.4 and 89.9 million tons, respectively.Based on 2019, it is estimated that the total number of

automobiles will increase by 89% in 2030 and 202% in 2040.Compared to 2019, it is predicted that the

total amount of CO2 emissions will increase by 97% in 2030 and 220% in 2040.As a result, according

to the automobile fuel types in Turkey in the event of temporarily deactivating of each 20% of the a

automobiles, CO2 emissions in 2040 will decrease 1.1 million tons for diesel vehicles, to 318 thousand

tons for gasoline vehicles and 377 thousand tons for LPG vehicles. Therefore, compared to 2020, a

reduction in CO2 emissions in 2040 will be 270% in diesel, 179% in gasoline and 98% in LPG.
