Carbondioxide and Carbonmonoxide.
Smog is a major form of air pollution that describes a smoky fog. Smog is formed when vehicle and industrial emissions interact with sunlight. This interaction also creates secondary pollutants.

Excessive light (light pollution), dramatically reduces the visibility of stars.
An exhaust system carries waste away from the car's engine. It helps reduce the amount of smoke and pollution that leaves the car and also reduces noise.
Cobalt exhaust refers to the emissions released from the burning of cobalt-containing materials, such as cobalt-based fuels or batteries. These emissions can contribute to air pollution and may have negative effects on human health and the environment.
There are a variety of ways to reduce vehicular pollution. Mass transit systems help reduce traffic congestion and improve efficiency through economies of scale. Switching to alternate forms of transportation may help reduce pollution. Catalytic converters change automobile emissions into less harmful molecules. Improving efficiency also reduces emissions. An automobile that achieves 47 miles per gallon (20 km/l) will exhaust less pollution than one that gets 15 miles per gallon (6.4 km/l). Carpooling is another pollution reducing strategy, that can make commutes more enjoyable. Most stragies aim at reducing vehicle miles driven or by improving vehicle efficiency.
It reduces the Life span.
