A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine and electric motor. While there are many types of hybrid vehicles, this paper will mainly focus on hybrid electric vehicles. Hybrid cars are a combination of electric and gas powered engines, and combine the best of both to be much more practical than just a simple gas powered or fully electric car. In the world today there are hundreds of ways to travel, like trains, planes, boats and cars. The most common way of travel in the world today is by car, easily shown by the statistic of the world has approximately one billion vehicles on the road (fueleconomy.gov). In the U.S. alone there are two hundred fifty three million cars and trucks on the road.

Hybrids are the most fuel efficient, cost productive, low emissions, and low repair cost. Although electric cars can go one hundred or two hundred miles at the time, it take almost six to eight hours to recharge your car battery. The battery of an electric car can usually only be recharged one to two thousand times and are generally extremely expensive to replace. Traditional gas-powered cars are time-tested and work fine for anyone; however, on average most of them only get around twenty four miles to the gallon. The lack of efficiency may start to be a real pain if a great deal of traveling is required since constantly having to stop and fill up with gas will be commonplace. Hybrid electric vehicles, on the other hand, provide the best of both worlds. The cars are equipped with a battery to provide power in-place of a traditional gas engine—like an electric car—but the hybrid still comes with an internal combustion engine to ensure the car can keep driving with a dead battery; all while recharging the dead battery. It is a great deal more convenient to recharge a battery while driving than to find a charge spot and wait the eight hours to …show more content…
Manufacturers have stepped up to the challenge of making a much more environmentally friendly fossil fuel automobile. The focus has been aimed towards preventing greenhouse gases, more specifically nitrous oxide emissions because of its correlation to smog production. Two key components have been added to the exhaust system of gas powered engines to prevent greenhouse gas: Exhaust Gas Recirculation (EGR) devices, and the Catalytic Converter. The EGR valve opens from back pressure from the car 's exhaust and channels it back into the combustion chamber combining the exhaust with intake air, the amount of oxygen in the mixture is reduced and its combustibility is also decreased, which causes fuel to burn at a lower temperature and produces less nitrous oxide (Lampton). In addition to the EGR circuit is the catalytic converter, “the job of the catalytic converter is to convert harmful pollutants into less harmful emissions before they ever leave the car’s exhaust system” (Nice). The catalytic converter is a metal box lined with metal such as platinum, gold, or rhodium. As the name implies, the catalytic converter acts as a catalyst to increase the rate at which pollution is removed with two different types of catalysts. The first stage of the catalytic converter is the reduction catalyst which uses a catalyst to rip nitrogen atoms from the molecule, therefore reducing nitrous oxide
