Diesel vehicles are among the most fuel efficient vehicles on the road. However, they are not the most environmentally friendly. Proper servicing and maintenance not only reduces the amount of pollution emitted by your vehicle, but also improves fuel economy. A tune-up is sometimes necessary to improve the performance and power of a diesel engine.

What is the operation of a diesel engine?

In today's world, where fuel prices are rising due to increasing demand and decreasing supply, you must select a cost-effective fuel to meet your needs. The diesel engine, thanks to the invention of Rudolph Diesel, has proven to be extremely efficient and cost effective.

Diesel is slightly more expensive than gasoline, but it has a higher energy density, which means that more energy can be extracted from diesel compared to the same volume of gasoline. As a result, diesel engines in automobiles offer better fuel economy, making them an obvious choice for transportation and heavy equipment. Diesel fuel is heavier and oilier than gasoline, and has a higher boiling point than water. On the other hand, diesel engines are gaining popularity due to their higher efficiency and cost-effectiveness.

The difference is in the type of ignition. While gasoline engines use spark ignition to ignite the fuel, diesel engines use compression ignition. The latter involves introducing air into the engine and subjecting it to high compression, which heats it up.

This causes the engine to reach extremely high temperatures, much higher than in a gasoline engine. Due to the high temperature and pressure, the diesel fuel introduced into the engine ignites.

In a diesel engine, air and fuel are introduced into the engine in different stages, unlike a gas engine, which introduces a mixture of air and gas. An injector is used to inject the fuel in a diesel engine, while a carburetor is used in a gasoline engine. In a gasoline engine, fuel and air are introduced into the engine and compressed. The mixture of air and fuel limits the compression of the fuel and, consequently, the overall performance.

A diesel engine compresses only air, and the compression ratio can be much higher. A diesel engine compresses at a ratio of 14:1 to 25:1, while a gasoline engine compresses at a ratio of 8:1 to 12:1. Combustion by-products are removed from the engine through the tailpipe after combustion.

During colder months, additional heat is provided by "glow plugs". Diesel engines can be two-cycle or four-cycle, depending on the mode of operation. Suitable engine variants are air-cooled and liquid-cooled engines. A liquid-cooled generator is preferable because it is quiet and has a uniformly controlled temperature.

Advantages of a Cummins diesel generator for indoor applications

Due to the following factors, diesel engines are much more efficient and preferable to gasoline engines:

  • Modern diesel engines have overcome the disadvantages of earlier models, such as increased noise and maintenance costs. They are now quieter and require less maintenance than gas engines of similar size
  • They are more durable and reliable
  • The fuel is self-igniting, so there are no sparks. The absence of spark plugs or spark wires reduces maintenance costs
  • Fuel cost per kilowatt produced is 30-50% lower than gas engines
  • An 1800 rpm water-cooled diesel unit can run 12,000 to 30,000 hours before requiring major maintenance. An 1800 rpm water-cooled gas unit typically lasts 6,000 to 10,000 hours before requiring maintenance
  • Because gas units burn hotter than diesel units, they have a significantly shorter life compared to diesel units

Diesel Engine Applications and Uses

Diesel engines are widely used in mechanical engines, power generators, and mobile units. They are widely used in locomotives, construction equipment, automobiles, and a variety of other industrial applications. Their dominance extends to almost every industry and can be seen on a daily basis if you look under the hood of everything that goes on.

Industrial diesel engines and diesel-powered generators are used in a wide variety of industries, such as construction, marine, mining, hospitals, forestry, telecommunications, subways, and agriculture, to name a few. The main application of diesel generators today is power generation for prime or standby backup power. For more examples, see our article on the different types of engines and generators and their common applications.

What is the difference between diesel and gasoline?

Both diesel and gasoline are derived from crude oil (LP gas is also a by-product of petroleum processing). Diesel, on the other hand, has up to 12% more energy per gallon than gasoline. This is one reason why diesel is more cost-effective than gasoline.

Due to the extremely high cylinder pressure, diesel fuel burns. As a result, diesel engines are built to withstand higher pressures and produce more power per stroke than gasoline engines, which ignite the fuel-air mixture with a spark from a spark plug. As a result of their compression ratio, diesel engines have higher thermal efficiency (i.e., power) than gasoline engines, which is another reason why diesel is more economical than gasoline.

Since diesel is commonly used in farm and construction site work equipment across the country, diesel for off-road use is widely available and is taxed less than diesel for on-road use, resulting in significant savings.

Isn't diesel a polluting fuel?

This is a common misconception, as many people remember that diesel and engines were less efficient in previous decades. Many of the harmful particles (such as sulfates and silicates) in diesel have been virtually eliminated thanks to recent technological advances, making diesel cleaner than ever.

Doesn't LP gas, compared to diesel, reduce emissions and our dependence on foreign oil?

LP gas is a derivative of petroleum processing that, like gasoline and diesel, depends on oil. However, LP gas emits "sky-high" levels of carbon monoxide compared to diesel, and LP gas also emits higher levels of other harmful emissions. All things considered, diesel is the more environmentally friendly option.

Is it true that using diesel saves fuel?

Undoubtedly. Because diesel engines have more power and fuel efficiency than gasoline, LP or CNG engines, you will use less fuel over the same period of time.
