Diesel Engines are more Efficient
One of the most significant advantages of a diesel engine compared to gasoline powered engines is that diesels are significantly more efficient. The engines are capable of converting approximately 45-50 percent of the fuel energy to power. The majority of gasoline engines are only able to convert approximately 30 percent of the gasoline energy to power the automobile.
Diesel Engines are more Reliable
Over the past 50+ years, diesel engines have proven themselves to be significantly more reliable than gasoline powered engines. One of the biggest reasons for this is the fact that a diesel engine does not require a high-voltage ignition system, and they also do not emit RF (radio frequency) that can cause issues with a vehicle’s electronic system.
Diesel Fuel Auto-Ignites
A big advantage of driving a car or truck powered by a diesel engine is that diesel fuel automatically ignites to power the engine. This advantage provides a big benefit since by not requiring spark plugs or wires, the overall maintenance costs of the automobile are significantly lowered as compared to gasoline powered cars and trucks. Even though a diesel engine uses a four-stroke combustion cycle like a gasoline engine (intake, compression, combustion, and exhaust), it directly injects the fuel to the combustion chamber.
Diesel Gasoline is Safer
Over the years, diesel gasoline has been proven to be significantly safer than regular gasoline for several reasons. First, diesel is fundamentally more difficult to catch on fire or burn than regular gas and will not normally explode when exposed to a high heat source. Next, since diesel fuel does not release gasoline fumes like regular fuel, the possibility of fuel vapors igniting and causing a vehicle fire is much lower. All of these factors contribute to providing increased protection for consumers in the event of a major car accident when driving their automobiles on the busy highways in both Europe
Lesser Carbon Monoxide Is Produced
Diesel engines produce significantly less carbon monoxide than gasoline powered ones do. This advantage also proves useful in non-automotive settings since diesel generators can be used in environments that gasoline exhaust would prove fatal (in mines, submarines, etc.) They are not carbon monoxide free; however, so auto owners must still take care to not start a diesel car or truck up in a garage with the door closed or other similar locations. The exhaust still contains a limited amount of the pollutant that can prove deadly if appropriate ventilation is not available.
It Is Easier To Turbo-Charge Diesel Engines
Compared to gasoline engines, it is much easier to turbo-charge a diesel engine. Designers invest a significant amount of time and effort into ensuring that a turbo-charged gasoline engine will not be put under excessive pressure and detonate or explode. Diesel engines on the other hand, can endure significantly more stress when turbo-charged, and they are only limited by the top-end strength of the engine.
Diesels run Synthetic Fuels Easily
Another big advantage of a diesel engine is that they can run synthetic fuels easily. Although non-petroleum-based synthetic fuels run hotter than diesel or traditional gasoline, most diesel engines can run the alternative fuel without any significant modifications to the engine or vehicle. Gasoline engines; however, require significant modifications in order to run on these fuels without causing major damage to the engine and supporting components
Diesel Engines Run Cooler
Diesel engines always run cooler than their gasoline counterparts. Since the engines are more efficient, there is less waste heat created during the engine operation. Since a diesel uses approximately 40% less fuel to produce the same power output as a gasoline engine of the equivalent size, there is less overall heat generated during the combustion process. One of the primary reasons for the better efficiency (and less overall heat generation) is the extremely high compression rations used by diesel engines to create power.
