It takes a lot more power and it puts a lot more wear and tear on your vehicle. According to Mitchell mechanics books your vehicles horsepower would increase by almost fifty percent if you were to get rid of the emissions controlling devices on your vehicle (mitchell). Imagine how much more powerful our vehicles would be today if we didn't have to put all of the electronic sensors and smog reducers on are vehicles these days.
The engines on the vehicle today are very sophisticated and technical pieces of machinery that we have out today. They are more complex than the first space ships like the Apollo shuttles. There are many different kinds of engines there are 2,3,4,6,7" 10,and 12 cylinder engines (Mitchell). The three and seven cylinder engines are rotary engines and the others are either inline or a V shape. That is dependant on what make and model of your car what kind of engine you can put in it. .

They make cars and trucks from 1975 to the present take the test and they don't make trucks over 3000 pounds of electric and solar powered vehicles do not have to take the emissions test (Connecticut 2&3). Imagine if we started the testing from the 1990's and present vehicles take the test we would have a lot more happy people and it would be less aggravating to the people that have older vehicles.

They both have a very important job on your vehicle one makes sure that your vehicle has the right amount of exhaust and air intake on your car so it is not putting out to many pollutants.
