Get reacquainted with the diesel car, and introduced to a new twist on an old technology

The diesel powered car has had quite the evolution and maybe even a resurrection if you will. Gone are the diesels of the past which you could hear and smell from a mile away. But what do you know about today's new diesel cars? Here are five facts to get you reacquainted to the diesel — and introduced to a new twist on an old technology.

The Efficiency of a Diesel Car

In a diesel car, the combustion process is different than in an internal combustion engine found in gas powered cars. Diesel cars don't have spark plugs. This is important because in a gas engine, fuel is ignited when a spark is generated from a spark plug. In a diesel engine, air compressed into a cylinder is heated at such a high temperature, fuel combusts when it's injected. No spark is needed. It's this equation that allows the diesel to offer better fuel economy.

Diesel Engines Built to Last

Diesel engines were built to withstand the combustion process. Very solid and strong parts are needed to endure extremely high temperatures and high compression ratios that make the engine work. Plus, diesel fuel lubricates engine components better than regular gas. As a result, diesel engines last approximately twice as long as gasoline engines.

The Ins-and-Outs of Diesel Fuel

Believe it or not, diesel fuel generates more energy than regular gasoline, while burning more cleanly in the process. Additionally, yesterday's diesel cars had an obvious and recognizable smell.  Not so today, thanks to the advent of low-sulfur diesel fuel. 

Finally, diesel fuel is proven to be safer than gasoline. You can burn diesel fuel in open air with a wick, without the risk of explosion. Gasoline, on the other hand, is highly flammable.  This comes in handy for spark plug ignition — not so great from a safety perspective.

Diesels Going Green

Today's cleaner burning diesels are considered green cars, and are now a purchase consideration among environmentally-conscious car buyers. They are as efficient, if not more efficient, than certain hybrid cars on the market today. They also give off fewer greenhouse emissions than a gasoline powered car.

Diesel Cars and Resale Values

Diesel cars typically hold their resale value better than gas powered cars, and even certain hybrids for that matter. And by some accounts, their resale value can be two to three times that of a comparable gas-powered car. Perhaps one reason diesel cars hold their value better is that; overall, most fuel efficient cars on the market today are maintaining their value over the long haul. Combined with the fact that diesel cars are extremely durable and diesel fuel prices seem to be normalizing back to levels of regular gasoline, todays newer, cleaner burning diesels could very well be a smart car purchase.

After reading all the benefits of diesel cars, you might be wondering why all cars aren't diesels. Perhaps their widespread adoption has been restricted due to preconceived notions of loud, noisy, smelly air polluters, or because it's taken a while for environmentally-conscious car buyers to consider them green cars.  Maybe it's because of limited diesel car availability.  Whatever the case, today's diesels are a different breed and worthy of purchase consideration.
