Advantages of a Diesel Engine
Mon, 03 Mar 2014
Since Rudolph Diesel invented his revolutionary internal combustion engine in 1893, diesel engines and conventional spark-driven combustion engines have been locked in competition for favor among the world’s engineers. For most of the past 100-plus years, the two technologies have enjoyed an uneasy peace with light-weight, spark-driven engines dominating the personal transportation, personal marine and early aviation fields, and heavier diesels being the engines-of-choice for larger vehicles like trucks, locomotives, ships and submarines. However, in the past 25 years, lighter-weight diesels have become competitive in automobile manufacturing. In Europe, 50 percent of all new cars are now diesel-powered.
Diesel engines use heat created from compression to ignite their fuel instead of the sparks that ignite the air-fuel mixtures in conventional gasoline-powered internal combustion engines. But, pound-for-pound, are they really better than gas engines? Many engineers would say “yes.”
Here are eight reasons why diesel engines are better than gasoline motors:
- Diesels are more efficient. Most gasoline engines convert about 30 percent of their fuel energy into actual power. A traditional diesel converts about 45 percent. And advanced diesels can hit about 50 percent.
- Diesels are more reliable. Because they don’t need high-voltage ignition systems, diesel engines never fail for lack of a spark. They also don’t emit radio frequency emissions that can interfere with a vehicle’s other electronic systems.
- Diesels run cooler. Because they are more efficient, diesel engines release less waste heat while in operation.
- Diesels last longer. Diesel engine parts are generally stronger than gas engine components, and diesel fuel has superior lubricating properties. As a result, diesel engines tend to last twice as long as gas-powered ones.
- Diesel fuel is safer. Diesel fuel doesn’t release fumes like gasoline does. It’s more difficult to burn and won’t explode like its lighter counterpart.
- Diesels are more easily turbo-charged. Put under sufficient pressure, gasoline engines will spontaneously detonate. By contrast, the amount of super- or turbo-charging pressures diesel engines can endure are limited only by the strength of the engines themselves.
- Diesels produce minimal carbon monoxide. This makes diesel generators useful in mines and submarines, environments in which gasoline engine exhaust would prove deadly.
- Diesel engines can easily accept synthetic fuels. Non-petroleum-based biofuels will run easily in diesel engines, whereas gas engines need to be significantly modified to accept such alternative fuels.
