The automotive industry has always been a little behind the times when it comes to sustainability. While the world is investing in green power, the typical car still runs on oil. Not everyone can afford a brand new, all-electric vehicle.
In fact, despite the strides made in green technology, major manufacturers seem more focused on cheating emissions tests, rather than the actual production of less harmful vehicles. With these latest revelations in mind, how green can any car ever be? More than just looking at the fuel source, what can be done to ensure your car is as harmless as you can make it?
One of the most basic factors of fuel-efficient driving is weight. If you want to improve your power-to-weight ratio, remove any excess items from your vehicle. Specifically, an empty boot (trunk) will make a noticeable difference in the fuel your car consumes while driving.
The same argument can be made for head-racks or other external additions. These disrupt the aerodynamics of the vehicle, adding air resistance and requiring more power from the motor. If you drive often enough, you can make a worthwhile dent in your fuel consumption and, as a result, reduce your emissions.
Rolling resistance, for instance, represents the force working against the vehicle as it pushes against the road surface. The best way to improve this situation is to use economy or eco tyres, which are designed to offer a low resistance. This is another example of reducing the power output of the vehicle, while offering the performance and speed your vehicle needs. This is still vital if you own an electric or hybrid vehicle, as they still require traditional, conventional tyres.
What you should pay extra attention too, however, are some of the additional eco-friendly features, such as the catalyst converters. These should always be recycled where possible, as they use rare earth metals such as rhodium, palladium and platinum.
Aside from the engine, it also helps to pay attention to the tyre pressure. The wrong air pressure changes the way you drive on the road, as too little can reduce the contact area and the overall impact created by the vehicle. This changes the rolling resistance, mentioned previously, thus creating a greater need for fuel.
Biofuels are legal in a number of countries, including America, and can often be used in diesel cars, yet the main problem lies in the model you may drive. While most diesel vehicles can be supplied with biofuel (and it’s always worth checking first), some may have the diesel particulate filter (DPF) in their exhaust system cylinders, rather than the pipe itself. The former causes issues with heating and can’t reliable handle pure biofuel. At the very least, however, you should be able to use some form of biofuel for your diesel car, as even many commercial forms of diesel are cut with a small percentage of biodiesel.
