Common Misconceptions About Diesel Engines

Posted on: 23 January 2018

Diesel engines are a very popular choice for heavy-duty trucks and vans, but they're also becoming somewhat popular for family sedans as well. This is because diesel offers many advantages over a standard petrol engine, some of which might make it a good choice for your next vehicle purchase. To ensure you invest in a car, van, passenger truck, or any other vehicle that is strong and durable for your needs, and that offers the fuel economy you expect, note a few common misconceptions about diesel engines you might want to discuss with a mechanic or salesperson before you make a buying decision.


You might assume that diesel engines are not fast, meaning they can't offer much pickup. It is true that a diesel engine is usually chosen for strength and not agility, but this doesn't mean that a vehicle with a diesel engine will somehow get bogged down or will lag when you accelerate. You may not have quite as much pickup and sudden acceleration from a diesel engine as you would a petrol engine, but you may not notice this difference when it comes to standard city driving. 


If you're near a large truck or other vehicle and notice any odd odours, this is probably caused by something other than the engine. Larger trucks are usually very rough on their transmissions and brakes, so you might notice the smell of burning metal or rubber as these pieces wear out, or the smell of burning fluids. These vehicles may also be prone to oil leaks because of how hard their engines work. A diesel engine, however, shouldn't create any odd odours, if it's maintained properly.


Another common misconception about diesel engines is that they create more pollution than standard petrol engines, and this is also incorrect. Diesel engines may produce more soot, but these engines often produce fewer fumes and emissions than gasoline engines. This is because diesel uses heat for energy; in turn, a diesel engine actually burns less fuel to run. You might also consider what is called bio-diesel, which is a diesel fuel that is made from biodegradable materials, such as farm waste. This type of fuel produces far fewer fumes and emissions and is much better for the environment than a standard diesel or petrol engine. Whatever your choice, as long as you maintain your diesel engine and ensure it doesn't burn oil or allow radiator and other such fluids to leak, it should be a very environmentally-friendly choice.
