Diesel Car Engines

Diesel engines in cars are becoming more and more popular in our society. A recent study showed that diesel's account for more than 50-percent of car sales in some European countries, an interesting statistic if you ask me.

As for the American market, car diesel engines are also making a comeback as they are cleaner, deliver more power, are more efficient and deliver higher MPG's than their gasoline engine counterparts. Diesel engines have long been the foundation behind our public buses, most trucks, and boats.

Gasoline vs. Diesel

Gasoline operates on a simple principle: gas is drawn in, compressed, and ignited by a spark. This will result in an explosion which moves the pistons up and down ultimately, making the car "go". This common set-up is used for gasoline powered vehicles.

Diesel engines, on the other hand, operate differently. The engine draws in air, compresses it to increase pressure and temperature, and then sprays in the fuel. Instead of an "explosion", the diesel fuel burns and expands to produce power. As you can see, the order in which the systems operate are backwards and they have to be for it to work.

Advantages of Diesel Engines in Cars

Diesel cars have some impressive advantages:

- Torque: They have a huge amount of towing power (torque) which makes them great for hauling, pushing, or pulling.

- Lifespan: In general, diesel engines tend to last longer than gasoline engines. This is because there is less "wear and tear" happening under the hood. For example, diesels can easily reach 250,000 miles and still have life left in them.

- Fuel economy: Diesel engines in cars are known for having generally better gas mileage than their gasoline counterparts. For instance, some of the 2012 Volkswagen diesel cars on the market get 30 mpg city and 42 mpg highway according to the EPA. In addition, because of how cars are tested by the EPA, diesel cars general get higher MPG's than the EPA gives credit.

- Safety: Since diesel fuel doesn't explode like gasoline, it automatically makes it a much safer than regular cars. In the case of an accident (knock on wood), the rider wouldn't have to worry about the car blowing up.

- Alternate: Diesel engines can run bio-diesel (non-petroleum based fuel) making them more versatile than gasoline powered engines. To make the switch, no "huge" modifications are generally needed, but always be sure to check with your local mechanic or automaker before making any big decisions.

Disadvantages of Diesel Engines in Cars

Unfortunately, nothing is perfect. For every good thing you find, there is bound to be a couple of bad things too.

- Noise: Some older diesel engines are louder than their gasoline counterparts. On newer models, however, many drivers will be hard pressed to tell the difference between the noise on a car's diesel engine and a gasoline internal combustion engine.

- Messy: if you've ever handled diesel fuel then you know how greasy and smelly it can be. Not to mention it can be difficult to get it off of your hands and clothes. You see, unlike gasoline (which evaporates), diesel fuel remains thick and consistent (like syrup).

Conclusion

As you can see the advantages of newer model diesel and especially turbo diesel engines in cars far outweigh the disadvantages. Diesel fuel is much cleaner than it was 3 years ago (in fact all diesel sold in the U. S. is now ultra-low sulfur diesel fuel) and diesel engines, in general, are more efficient and get better MPG's than standard gasoline engines.
