Research also shows that engines with less power come to pollute more than the equipment with greater capacity
Data released on Tuesday (15) by the Ministry of Environment show that alcohol fuel can pollute as much as gasoline. And the engines with less power come to pollute more than the equipment with greater capacity. The calculation was based on the Green Rating, which tells, for vehicles manufactured in 2008, measurements of the emission of three greenhouse gases - carbon monoxide (CO), hydrocarbons and nitrogen oxides. With regard to CO2, a major greenhouse gas, alcohol, because it is renewable, has its emissions offset by the absorption of gases made by the leaves of cane sugar on the crop.

In the ranking of 258 tests on pollution and emissions that companies submitted the vehicles, the best grades (ranging from 0 to 10) were given to cars that used gasoline at the time of testing. The winner was the Ford Focus 2008, engine 2.0 DOHC I-4 SFI, who played for the myth that vehicles with smaller engines pollute less. On the contrary. The first to seventh place among the least polluting, most studies were more powerful engines, of 1.4 to 3.5 cc.

According to Marcio Veloso, analyst Environmental Control Program Air Pollution by Motor Vehicles IBAMA, the smaller displacement engines pollute more because they require more power - and therefore less fuel efficient - to make the car move. The alcohol, burn faster than gasoline, releases more gases.

It fell to a Fiat Uno with engine displacements of thousand eighth among the least polluting. By coincidence, at the time of testing, the company was using alcohol as fuel. The emission of CO2, a Fiat engine capacity of one thousand, eight valves, and L5 engine with gasoline, achieved the 10, which represents zero release of gases. The second in CO2 emissions fell also a Fiat Uno Way but model, 1.0 engine, petrol. He earned 9.9 note.

The table with all notes for vehicles manufactured in 2008 can be accessed on the Institute of Environment and Natural Resources (IBAMA) - www.ibama.gov.br - Note the green link. There, you can check if the car is more or little pollutant and emits more or less gases that contribute to global warming. You can also find details about the pollutants emitted

Vehicular pollution, 99% result from the release of carbon monoxide, hydrocarbons and nitrogen oxides. "We think that disseminate the data could lead owners to see which vehicles that pollute or emit more or less gas," said Environment Minister Carlos Minc.
