Fuel-injected motors emit dangerous gases, such as nitrogen dioxide, hydrocarbons, and carbon monoxide. If these contaminants were pushed out unaltered through the exhaust system, they would cause more damage to the environment. Thankfully, with the help of catalytic converters, these gases are conv...
My parents had stories of cars in WW2 running on towns gas using a rubber bag on roof or cars running on carbon monoxide generated from a charcoal burner. These were times of extreme petrol rationing, so surely we can do better, second time around. One thing is for sure, people are ...
Reduction: Nitrogen oxides (NOx) are reduced by the catalyst, which means that they react with a reducing agent, such as carbon monoxide or hydrocarbons, to form nitrogen (N2) and water. This reaction also occurs on the surface of the catalyst and is facilitated by the presence of the prec...
Better Mileage WASHINGTON WINDOW With the price of gasoline increasing rapidly, more from war jitters than actual shortages, the next Congress is likely to take a closer look at alternative motor fuels. Engines fired by gasoline and diesel fuel emit 66 percent of the carbon monoxide, 50 percent...
In addition to carbon monoxide, automobiles emit a variety of hydrocarbons(HC). Hydrocarbons are a group of organic compounds consisting of carbon and hydrogen atoms. They are either evaporated from fuel supplies or are remnants of fuel that did not burn completely. ...
In 1996, the U.S. EPA began requiring OBD-II systems in all passenger cars and most light-duty trucks. These systems include emissions system monitors that alert the driver and the technician if an emissions system is malfunctioning.
