Here Is All You Need To Know About Engines, Pollution and Steps to Overcome it

Air pollution is one of the key issues of the modern world. As Robert Orben said, “there’s so much pollution in the air now that if it weren’t for our lungs there’d be no place to put it all.” There are so many contributing factors to this worrying state of affairs, however, car engines are at the top of the list.

There are a hell lot of cars running on the roads around the globe. These cars not only contaminate the air but also play a role in polluting land and water. On that account, there is a growing awareness among the masses about the severity of the issue. People are looking for options to find solution to the car pollution issue.

Since most of the car engines are powered by diesel or petrol fossil fuels, their exhaust pipes emit pollutants, half of which are nitrogen oxides. This gas is a chief cause of global warming in the world. Also, these gases impart an extremely unhealthy impact on the organ system in the body. Let us cast a glance at the effects of air pollution.

Effects of Air Pollution on Health and Environment

It is not only the lungs which are affected by the pollutants from vehicle emission. But these tailpipe pollutants are a grave threat to human life at every stage, and in some cases these can even lead to death. Pollution is playing a vital role in Global warming, which is bringing forth more repeated and extreme heat waves.

Air pollution causes problems in normal functioning of the human body organs. These pollutants can cause respiratory illness, cardiovascular dysfunction, exhaustion, headache with anxiety, irritation of eyes, itching in nose and throat, harm to reproductive organs, impairment of the liver and nervous system.

Along with damaging human health, air pollution also causes a lot of environmental

Hazards. Acid rain is simply a rain but precipitated with injurious pollutants such as nitric and sulphuric acids. These acids are formulated with the reaction between nitrogen oxides and sulphur oxides which are emitted by the combustion of fossil fuels. Formation of smog, which is becoming a grave problem in the big cities is also the outcome of vehicle emissions.

The Constituents of Air Pollution

Air pollution from vehicles can be divided into two categories. One is primary pollution and the other is secondary pollution. The Primary type of pollution is released straight into the atmosphere. Whereas the secondary pollution is the outcome of chemical reactions between the same pollutants in the atmosphere.

Vehicles produce air pollution all through their lives. Add to that the pollution that is released during vehicle operation manufacture. Further releases are related with purification and distribution of fuels.

  1. Particulate matter

Particulate matter or PM is type of is black powder usually seen inside the vehicle’s exhaust. These fine particles are less than one-tenth of the diameter of a human hair. Despite seeming harmless, it poses a grave danger to human health owing to its capability to penetrate deep in the lungs. Diesel exhaust is a chief sponsor to PM pollution.

  1. Nitrogen Oxide

Nitrogen Oxide or NOx is one of the dangerous gases emitted by vehicles as a result of combustion cycle. These pollutants fall in the category of primary pollutants and cause lung irritation. With that, it also weakens the body’s resistance against respirational infections like pneumonia and influenza.

  • Carbon Monoxide

Carbon Monoxide, which is usually written as CO is an unscented, colourless, and toxic gas. It is produced by the burning of fossil fuels such as petrol and is discharged mainly from cars and trucks. Carbon Monoxide is a very poisonous gas as when breathed in, it hinders the oxygen from reaching the brain, heart, and other organs which can directly lead to death.

  1. Sulphur Dioxide

Sulphur Dioxide is a gas which is exhausted by Power plants and motor vehicles. It is formed as a result of burning sulphur containing fuels such as diesel and coal. Sulphur dioxide reacts with the gases present in the atmosphere. Resultantly, fine particles are formed and pose extremely harmful threats to human health, especially to children and asthmatics.

  1. Greenhouse Gases

The vehicles also produce carbon dioxide gas which contributes to global warming and climate change. Moreover, emissions from cars, trucks share over one-fifth of the total global warming pollution. Modes of transportation including airplanes, ships and trains produce thirty percent of all heat-trapping gas emissions.

  • Steps To Counter Air Pollution

Any sane and compassionate person would be keen to adopt air pollution solutions without giving it a second thought. There are many ways one can contribute in encountering the pollution caused by vehicles. One of the first steps is controlling and setting straight your driving habits. Green driving habits can help control the pollution in a significant way.

  • All the electrical gadgets and Air conditioning systems which are installed within the vehicle eat up a lot of energy. Turning them off when they are not in use would reduce the carbon footprint of your car a great deal.
  • People tend to keep their car engines on while waiting inside their car. However, it is suggested to turn off the car engine meanwhile. Because idling wastes your fuel and money and thus add to the pollution without doing anything. Therefore, you must reduce the time of idling as much as you can.
  • You can also seek help from green technology. Car manufacturers are producing engines which stop automatically when the car comes to stationary. And when it is needed, the engine resurrects quite fast. Such type of green technology helps you save fuel, and money makes sure you play your part in reducing pollution.
  • A car in a good working condition is a guarantee in itself that it won’t add to the pollution as much as an old dilapidated car. It is quite evident that a badly maintained car produces a lot of pollution. Therefore, keep your vehicle in a nice working condition as this will not only be beneficial for you but also for the environment.
  • It might seem a bit weird to you but keep your car tyres pressure under check. Properly inflated tyres can really help you decrease your fuel consumption. According to an estimate, it will reduce your fuel consumption and, in turn, pollution by up to 3%.
  • Excess and unnecessary load in your car increases the weight of the car and thus, more amount of fuel is required to run it. Therefore, you should get rid of the excessive load in your car. WikiHow says that every 100 pound increase in your car’s weight leaves you with up to 2% less mileage. Thus, more pollution due to more fuel consumption is obvious.
  • Drive less. Yup, this is the best tip you shouldn’t miss out on. This is either the least or the most you can do to play your role in the reduction of pollution. Driving less will mean less consumption of fuel and hence less contribution to pollution.
  • Following the strategy of finding the shortest and least crowded way to your desired destination can be really useful in limiting the fuel consumption. This will let you drive seamlessly at a constant speed. This way less fuel will be consumed and less pollution will be produced by the vehicle.
  • It is also advised that while ordering home deliveries or online shopping, ask your shipper to send all your parcels in a single shipment coupled with minimal packaging. Moreover, when opting for arranged home deliveries, try to stay as flexible as possible by selecting extended time frames so that the delivery trucks can adjust their routes and evade extra excursions.

Fuel Efficient Vehicles

In the endeavour of imparting a green impact to the environment, the choice of the vehicle also matters a lot. It is common sense that some vehicles are more fuel efficient and provide better carbon emission numbers than others.

Therefore, when you decide to buy a new car, search for vehicles with a better fuel efficiency coupled with low greenhouse gas emissions. At one hand, these cars will save you money and fuel and on the other hand they will let the Mother Nature flourish in a better way.

Following tips can come handy while buying green vehicles.

  • The Environmental Protection Agency (EPA) has rolled out Green Vehicle Guide in order to facilitate to eco-friendly people. Thanks to this guide, anyone can learn about vehicles which are green and which aren’t. Green Vehicles include:
  1. Electric Vehicles
  2. Hybrid Electric Vehicles
  3. Hydrogen Fuel Cell Vehicles
  4. Cleaner Burning Petrol Vehicles
  • The EPA has also chalked out a Fuel Economy and Environment Label which enables the vehicle enthusiasts to compare all vehicle models in order to find out which of the vehicles are most fuel efficient and environment friendly. This information is easily available across internet.


The problem of pollution is getting bigger and bigger and it is a high time we understand what dangers are lurking around and how to deal with them appropriately. Vehicles are indeed a necessity of modern day life, but what would be their utility if no life exists? Think about it and play your role to contribute towards a cleaner and greener world.
