A perfectly maintained car will pollute more than necessary it if is driven carelessly. Car emissions will be lower if you use common sense when you drive and follow the basic rules of the road.
You will save bas by turning the engine off and restarting it again if you expect to idle for more than 30 seconds. Park your car and going into the restaurants, banks, and drive up pharmacies instead of idling in the drive-up lanes will prevent pollution.
Whenever possible, plan your trips to avoid driving in rush hour and peak traffic periods. Drive smoothly; avoid drag racing starts and slamming on the brakes at the stoplights. Accelerating and decelerating gradually, anticipating stops and starts for traffic lights, and changing traffic speeds will not only prevent pollution but will improve the miles per gallon.
Running the air conditioner in your car increases the load on the engine, which can increase emissions and decrease the fuel economy. As an alternative try opening a window or the fresh air vents to cool the inside of your vehicle. Park in the shade, if possible, to prevent heat builds up in your car from setting in the sun. Keeping the interior temperature of your car more comfortable lessens the pollution and waste that occurs when gasoline evaporates from the engine and gas tank.
Your car burns more gas and emits more pollution when the engine operates under high loads. Running the air conditioner, quick acceleration, high-speed driving, climbing grades, revving the engine, and carrying extra weight create extra loads.
Emission control systems take longer to warm up and become fully operational in cold weather, but the days of idling are long gone. The vehicles today do not need to have lengthy warm up periods, they are most efficient when they are driven. Warming up your car for a lengthy period of time in cold weather can actually cause excessive engine wear.
Prevent spills and overfilling when fueling your vehicles, spilled fuel pollutes the air when it evaporates, avoid “topping off,” especially in hot weather. These precautions need to be applied to any engine that is being refueled wither it is a motor vehicle, outboard motor, power equipment such as lawnmowers.
