When it comes to purchasing equipment with petrol engines or getting a replacement petrol engine, many companies are wondering about environmental compliance. In the modern world, where taking care of the environment is not just trendy but regulated by law, keeping your carbon footprint low is a necessity.
Some companies have previously considered getting diesel engines as an alternative to their petrol counterparts, although it is now recognised that diesel emissions also carry a significant environmental and health risk. Which engines are more environmentally friendly?
When you take a closer look at both diesel and petrol, you will find that neither of them is particularly environmentally friendly. While petrol is a more productive fuel, it produces a host of airborne contaminants. Diesel seems to be more natural, but the contamination is substantial as well.
Both diesel and petrol produce:
- Carbon dioxide – overall, diesel engines produce more carbon dioxide than petrol engines.
- Carbon monoxide – Petrol engines produce some CO while diesel engines produce none.
- Nitrogen oxide – Diesel engines produce more nitrous oxides than petrol engines due to higher operating temperatures.
- Hydrocarbons – Petrol engines transmit considerably more benzene to the atmosphere than diesel engines.
- Suspended particulate matter –Diesel engines produce bigger amounts of particulate matter than petrol equivalents.
- Lead – Petrol engines produce more lead than diesel engines, although most plant engines now use lead-free or reduced lead petrol.
As each engine produces several types of harmful emissions, neither can truly be considered environmentally friendly!
Studies And Research
For a long time, diesel engines were considered “cleaner” than petrol. Several studies seemed to show that it makes more sense to use diesel in cars and other equipment. In the early years of this century European governments introduced lower taxes for diesel cars compared to petrol. However, new findings suggest a completely different picture.
In 2017, The European Federation for Transport and Environment conducted a new study, which showed that diesel engines produce more CO2 than petrol engines, thus polluting the environment and posing health dangers.
The study reviewed outputs from both diesel and petrol cars. It found that a car with a diesel engine emits 3.65 tonnes more CO2 than a car with a petrol engine. As a result, diesel engines are more harmful.
When it comes to smaller machines, such as chainsaws or lawnmowers, the emissions are not as substantial as a car. However, if you care about the environmental and operator health, petrol engines seem to be the better choice.
Which One Is Truly Better?
Are petrol engines cleaner than diesel? Yes and no. When it comes to environmental compliance, both engines have their pros and cons. Accordingly, when you choose the fuel for your equipment, it’s important to look at their efficiency.
The latest replacement petrol engines are usually more efficient than diesel engines. They are better suited for smaller equipment used in the construction industry.
