Diesel Versus Spark Engine Ignition

As you may already be aware of, diesel engines are  more efficient than gasoline engines of the same power, resulting in much lower fuel usage.  For an efficient turbo diesel, the average is 40% more miles per gallon.  The higher compression ratio with  diesel engines help to raise efficiency, but diesel fuel also contains around 15% more energy per unit volume than gas.

Diesel engines that are naturally aspirated are far more massive than gasoline engines of the same power for two reasons.  First, it takes a larger capacity  diesel engine than a gas engine to produce the same amount of power.  Essentially, this is because the  diesel can't operate as quickly.  The rev limit is slower, because getting the correct fuel to air ratio into a diesel engine fast enough is more difficult than a gas engine. The second reason is due to the fact that a diesel engine needs to be stronger to withstand the higher combustion pressure needed for ignition.

Diesel engines also produce very little carbon  monoxide as they burn the fuel in excess air except at full loading capacity, where a full quantity of fuel is injected per cycle.  They can however,  produce a black soot from the exhaust, which consists of unburned carbon compounds. 

Often times, this is caused by worn injectors, which don't atomize the fuel sufficiently enough, or a  faulty management system that allows more fuel to be injected that can then be burned with the available air. 

For commercial use that requires towing, diesel  engines tend to have more desirable torque.  Diesel engines tend to have their torque peak quite low in their speed range which provides smoother control over heavy loads when starting from rest, crucially allowing the engine to be given higher loads at low speeds than a gas engine.

The lack of an electrical ignition system in diesel engines improves the reliability.  The high durability of diesel engines is also due to the overbuilt nature as well as the combustion cycle, which will create a less violent change in pressure when  compared to a gasoline type spark ignition engine. Diesel fuel is also a better lubricant than gasoline, so it is less harmful to the oil film on piston  rings and cylinder bores - making it routine for diesel engines to go 250,000 miles or more without  having to be rebuilt.

For several reasons, diesel proves to be better than spark engine ignition.  Diesel engines last a lot longer, they offer more torque, and they are also more reliable.  They are also more expensive as well, although you get what you pay for.  If you have  never owned a diesel vehicle, you owe it to yourself to see everything they offer you - and you'll find yourself a very satisfied customer.

Diesel Versus Gasoline

A diesel engine will go much farther on a gallon of fuel that the standard gasoline engine because of their designs, and due to the higher energy density of a gallon of diesel fuel.  But, it also takes a bit more oil to manufacture a gallon of diesel than a gallon of gas, with  the production and refining processes for  diesel producing more gases that trap heat.

Therefore, when you consider the relative merits of deisel and gas cars, try knocking the MPG estimates for the diesel car down by 20 percent. A diesel vehicle will cost you a bit more,  so you'll get more bang for your buck from a gasoline vehicle. 

The nasty rumors you hear about diesel are  true as well - diesel is less refined than gas, or in other terms it's dirtier.  Diesel  vehicles also emit more particulate matter and NOx, both of which are serious health hazards and air pollutants.  Current diesel engines are more polluting per each mile they are driven than gas engines. 

Using biodiesel on the other hand, will improve this situation.  If biodiesel is available in your area, you'll still need to examine  whether a diesel is the right vehicle for you.

When you consider the facts, you have to ask yourself which models you can afford, what is the MPG, will engine be succifient for you, and the number of passengers the vehicle will accommodate.  Then, given your budget, you can go from there.

There are numerous gas and diesel vehicles available, all you have to do is decide which one is right for you.  If you research carefully, you'll have the perfect vehicle for your entire family.

Diesel Passenger Vehicles

Both diesel cars and light trucks are receiving a  lot of attention in the United States as a near term strategy to achieve fuel economy and climate change goals. 

The renewed interest in diesel as of late stems from its potential to improve passenger vehicle fuel economy.  The best diesel passenger vehicles of today are more efficient on fuel than their gas counterparts, helping to reduce carbon  emissions by 30 percent or more.

There are some auto makers that are talking about re-introducing diesel into light duty markets as a solution for reducing global warming pollution from both cars and trucks.  Another important reason is that the higher efficiency of diesels will provide a quick fix for manufacturers who are struggling to meet federal fuel economy  standards for light trucks.

Even if the efficiency benefits of diesel do yield real world improvements on the economy, the potential climate change benefits are modest.

Even though diesel achieves more miles per gallon than gasoline, many are concerned about the impact that diesel passenger vehicles have on the economy.  From time to time, the combustion in the engine can cause black emissions to spit from the exhaust, which is actually very bad for the economy.

While gas is actually the worst, diesel is taking strides to improve engines and the impact on the economy.  Diesel is getting more and more popular these days, as gas prices continue to rise and rise.

Although diesel engines can have an impact on  the economy, they are the way to go for those looking to conserve mileage.  Diesel vehicles cost more than gas vehicles, although they will offer you more than you can expect.  If you are looking for a quality ride, diesel is the way to go.
