All vehicles produce emissions as fossil fuel is burned and converted into energy. Unfortunately, like most other emissions, these usually end up in the atmosphere.
The damage to the environment and the planet’s population is evident. Emissions mainly comprise carbon monoxide, nitrogen oxides, and hydrocarbons, which create numerous problems. They cause smog, acid rain, and health problems and allegedly deplete the layer in the atmosphere that protects us from the sun’s direct rays. Personally, having researched both sides of the argument, I am not entirely sold on the arguments for global warming. But the damage to people’s health is genuine and does concern me.
Trace elements in fossil fuels have harmful effects, too. Sulphur and heavy metals cannot be eliminated entirely during refining. When fuel is not fully combusted, these emissions become a danger to health.
You can take steps as an individual to ensure that your contribution to these emissions is minimized. Poor maintenance and a fuel system and engine made inefficient due to deposit build-up are significant contributors to excess emissions. Using higher quality fuels and/or regular fuel treatments/conditioners can help ensure these areas – as well as the components designed to neutralize or capture emissions – are clean and function efficiently. This includes the catalytic converter and diesel particulate filters for most diesel vehicles that now have them. By tending to these areas, we can help keep harmful engine emissions to a minimum.
Ensure engine sensors, particularly those contributing to air/fuel ratio calculations, have not degraded. Dirty airflow sensors, in particular, reduce combustion efficiency and increase exhaust emissions.
There are cars available in the market today that are designed to be more environmentally friendly, such as hybrids. These cannot be ignored if you are serious about reducing car emissions. However, the actual benefits of electric or partly electric vehicles are widely debated. Some argue that the harmful emissions that are prevented are negated by the cost of manufacturing and later decommissioning the battery cells for these vehicles.
In addition to better maintenance and vehicle alternatives, behavioral changes also can reduce emissions. It’s a tough bullet to chew, but have you ever considered driving less? Why should you drive everywhere if you can walk or cycle there? It’s a serious point that we all should consider. Even carpooling or using public transportation can help cut emissions by having fewer vehicles on the road.
What do you do when you are caught in traffic? Most people just let their engines idle and continue using fuel to create emissions. The best thing to do is switch it off altogether. Car emissions peak at rush hour, so if more people turned off their engines, there would be considerably less pollution. BMW officials, for their part, are addressing this issue with their Auto Start Stop function, which automatically turns off a vehicle when it comes to a complete halt and then restarts it automatically when it is time to move. In time the problem caused by idling will likely become moot as most other manufacturers incorporate similar features.
While buying a new vehicle or walking to work might not be an option for you, there are steps you can take to reduce the emissions you create. And it can be as simple as keeping your engine clean.
As mentioned earlier, fuel system and engine deposits considerably increase car emissions. The engine’s efficiency is reduced as the flow pattern deteriorates on fuel injectors. As a result, more hydrocarbons are produced, depositing carbon in the combustion and post-combustion areas such as the exhaust gas recirculation (EGR) system. This reduces efficiency further and results in even more car emissions. It’s a dwindling spiral, and ‘before and after’ emissions tests demonstrate the improvements made by cleaning the fuel system.
While some fuels are marketed as having cleaning properties, they don’t use fuel catalyst chemistry to prevent deposit build-up, even with the latest fuel-efficient engines. The answer is to use professional treatments regularly to keep the fuel system and engine free of deposits.
