Diesel was on the brink of becoming an energy-efficient source of power, but that trajectory was halted by a scandal in 2015 that seemingly scared car manufacturers away from integrating diesel powertrains.
Opinions vary greatly when considering whether diesel will remain a viable source of fuel for vehicles, particularly given the push toward electric vehicles. But given diesel’s advancements — more fuel efficient, far fewer emissions — the technology isn’t going away any time soon.
There is a misconception that diesel fuel is consumed faster than gasoline, but in automotive vehicles, a diesel engine is up to 30 per cent more fuel efficient than an equally sized gasoline engine.
The molecules of diesel fuel contain more energy than gasoline fuel. That means you will have a higher energy output and more power behind your pedal. It also makes your vehicle’s combustion process more efficient.
That makes diesel an attractive option for any vehicle. Though diesel engines are more expensive to manufacture, diesel fuel can last twice as long as gasoline (depending on your driving habits).
Diesel engines have a checkered past. Many believed diesel was unclean, used by trucks and tractors. This belief has created a lasting stigma, though many of the arguments against diesel are outdated and based on a standard that no longer exists.
That’s not to say diesel is a perfect system. It’s just a reformed one. There is less sulfur in modern fuel, and filtration is better, making diesel cleaner than ever. Modern diesel uses after-treatment systems to clean the exhaust, so emissions are as clean as gasoline.
Diesel engines were once incredibly noisy. Modern technology has changed this, making a car or truck diesel engine as quiet as a gasoline engine. Some say you wouldn’t be able to tell the difference.
Diesel engines are powerful. They are used in cars, trucks, cargo and cruise ships, trains, buses, and construction vehicles. Diesel fuel is clearly critical in today’s transportation industry, importing and exporting goods, and construction.
To keep up with electric vehicles, diesel will require the rapid integration of new technology. Cars and trucks have advanced greatly over the years, those with diesel powertrains even more so. Diesel powertrains must match strict regulations in the United States.
Car and truck manufacturers are already introducing new technology in diesel engines. Innovations include combustion chamber modifications and sound reduction to allow diesel engines to be cooler and quieter as they combust. The changes made to diesel – in the past, present, and future – are vital to diesel’s survival against electric cars and the existing popularity of gasoline.
