Indian car industry is predominated with a number of old and new cars. The increasing number of cars on road is the primary cause of increasing environmental pollution.

Petrol engines comprise of a combination of gases including the hydrocarbons, carbon monoxide, and oxides of nitrogen. These gases present in the combustion engine blend with air to produce power to run the car. Some of the mixture is used for power production and the rest is expelled from the combustion engine. The expelled gases cause car pollution.

To a certain degree, this emission is acceptable but higher level of pollution depletes the ozone layer and causes harm to the entire ecosystem. This needs to be controlled. Currently, Indian car manufacturers are working to produce fuel efficient engines to reduce the amount of pollution. Some leading players in the auto industry are also working on green cars and electric cars. Till the time, the country is not ready with the required number of green cars, electric cars and fuel efficient cars something has to be worked in order to reduce the extent of automobile pollution.

Here are top 10 tips to reduce car pollution:

1. The first thing is car maintenance. Maintenance and service at regular intervals helps reduce the amount of emissions.
2. Oil change at recommended time interval is also essential. Change the oil even if the car is unused for several months. Avoid using low grade oil and lubricant.
3. Car tuning up is also important to improve the performance and gas mileage which lowers down the level of pollution. Replace the spark plug immediately if required.
4. Sweep away the dirt from the carburetor and adjust the idling speed at every 3000 kms.
5. Drive the car at a steady speed. This improves the fuel economy of the car. High fuel efficiency means less fuel consumption and less emissions.
6. Tyre pressure also plays a vital role in fuel consumption. Proper inflation is very necessary to run the car smoothly or else the car wheels will simply drag on the road. This requires more fuel and henceforth, more emissions. So, check wheel alignment and tyre pressure at regular intervals.
7. Don't idle the car for more than two minutes. Switch off the engine if the car is stopped for a couple of minutes. Also reduce engine warm up time during winters. Idling for longer periods result in excessive engine wear which takes in more fuel for combustion and expels more pollutants.
8. If possible combine car trips. If there are two people travelling from the same place to the same destination, they can use the same car for commuting. This will at least reduce one car on road. One plus one becomes two and slowly the number will increase to ten and hundred out of the thousand cars running on road.
9. Unload any extra weight from the carriage. Excess of weight in the car trunk adds to the car weight and exerts more pressure on the engine to pull the vehicle. Increased pressure on the engine means high fuel consumption. This results in high degree of pollution.
10. It's always good to know the basic technical specifications of the car. There are certain signs that indicate faulty engine. Car owner should be aware of that signs so that immediate repair is done. Black smoke indicates excess of gas in the fuel mixture. This also indicates emission of excessive hydrocarbons. This needs to be checked. Sudden drop in the gas mileage also indicate engine trouble shooting.
