Hybrid Cars

Hybrid Cars The impact of gas emissions on the global warming is evident. Humanity causes severe weather by a number of ways, including pollution. People have always polluted their surroundings, but throughout much of history, pollution was not a major problem. The or "Greenhouse effect" we are now experiencing is a result of carbon dioxide we have dumped into the air. It turns clear, odorless air into hazy, smelly air that harms health, kills plants, and damages property. In general, air pollution and warmingglobal warming results from pouring hundreds of millions of tons of gases and participates into the atmosphere including the major greenhouse gases such as carbon dioxide, methane (CH4), the halocarbons (CFCs) and nitrous oxide. Kyoto protocol (1997) introduced strict laws for car manufactures aimed to reduce the impact of gas emission on global worming (Kyoto Protocol, 2005). Car manufactures have been forced to develop new clear technologies to reduce the level of gas emissions dumped into the air. How they work? The technological developments do much to control pollution cased by older technology. Various methods of reducing pollution from automo¬bile engines have been developed recently. Examples include new additives to replace tetraethyl lead in gasoline, and devices to remove pollutants from exhaust and make combustion processes more complete. One more alternative sollution is a hybrid car. A hybrid car combines more sources of power: a rechargeable battery and gasoline. Its full name si the gasoline-electric hybrid car, because it is a mixture of a gasoline-powered car and an electric car.The battery is needed to provide extra acceleration power. "When the car is stopped, hybrid gasoline motors can shut off and run off their electric motor and battery" (Hybrid Cars, 2005). There are two variant of a hybrid car: a parallel hybrid and a series hybrid car. The difference is that a parallel hybrid car consistes of a fuel tank, which supplies gasoline to the engine while in the latter, a generator is turned by the gasoline engine. It can charge the batteries or power an electric motor that drives the transmission (How Hybrid Car Works, 2005). The basic components of a hybrid car include: gasoline engine, fuel tank, electric motor, generator, batteries, and transmission. "Both the engine and the electric motor can turn the transmission at the same time, and the transmission then turns the wheels" (How Hybrid Car Works, 2005).
How they help the Ecosystem and the Environment? Hybrids innovative technology is an alternative energy solution which help to reduce the risk of global warming. On the one hand, hybrids reduce fuel emissions because the hybrid engine draws on the battery and not gasoline when accelerating. On the other hand, hybrid gasoline motors can shut off when the car is stopped and run off their electricity.
