In this paper i will show how Gasoline and Diesel engines compare and contrast, the pros and cons of both gas and diesel my opinion on which one is better and which one benefits you the most.When its comes to engines, a lot of people know little information.
Yes we know that they power your car and maybe your lawn mower but do you know what goes on inside and what chemicals they produce? Did you ever also wonder why the two engines have two separate fuels In this paper, I will explain what goes on inside of gasoline and diesel engines and explain the differences in reactions and chemicals as well as structure changes that causes different reactions.The anatomy of an engine is very complex, but gasoline and diesel engines are slightlydifferent in one way. In a gasoline engine, the oxygen and fuel is ignited by a spark plug, but in adiesel engine the fuel and oxygen is ignited by the heat from the engine not a spark plug. Whenthe spark plug is not present in the engine, the combustion reaction is different. With a gasolineengine the combustion reaction is 2C 8 H 15+ 25O 2? 16CO 2+ 18H 2 O and with a Diesel engine, the combustion reaction is C12 H 23+ 71O 2? 48CO 2+ 46H 2 O . They are similar but are different because of the different fuel type for a Diesel engine. As you can see, they have theexact same elements in the exact same order but the number of atoms is very different. The sparkplug also plays a role in the combustion reaction with the temperature of the reaction.
In thediesel engine without the spark plug, the flame that is created is ignited to about 3000°F.According to discovery education, In a gasoline engine with a spark plug, the flame is onlyignited to 3880°F. This also plays a big role in the combustion reaction.Here are some pros of having a diesel truckpros:diesel trucks get great mileage,they produce up to 30% better fuel economy then regular gasoline,uses more reusable energy than gas, never need engine tune-ups,no spark plugs,built to take more compression, gives the car more torque than gasoline engines Cons:they are more expensive than regular gas,need more maintenance because of oil,air and fuel filters, if you don’t take care of the filters it will break down the whole engine.
so looking at just a couple of pros and cons you can see that there are more pros than cons.Everyone knows not to breathe in the fumes that come from the tailpipe of a car becauseit is harmful to your lungs and can even cause death. But many people don’t know what the gas iscomposed of. The exhaust gas is composed of nitrogen, water vapor, and carbon dioxide. In aregular gasoline engine, the fuel that is combusted only contains 71% nitrogen, 14% carbondioxide, 13% water vapor, and no oxygen. In a diesel engine, the fuel that is combusted onlycontains 67% nitrogen, 12% carbon dioxide, 11% water vapor, and 10% oxygen.so incomparison, diesel engines limit less harmful fumes into the Earth’s atmosphere.
Another bigdifference between gasoline and diesel engines is that diesel engines, as you know, produce ablack soot from the tailpipe. According to Daily Caller, “Thick clouds of smoke are producedbecause fuel is pushed from the engine without being completely burned, and then leaves thepickup as black soot — and diesel is the only fuel with that sooty power.”In conclusion, many pros and cons are found between gasoline and diesel engines.
Somebeing the dangerous gases emitted and others being the combustion reactions inside the engines.While the black smoke from a diesel engine may look harmful, it’s surprisingly somewhat lessharmful than a regular engine. But hopefully someday we will not have to worry about howharmful our engines or to the environment, because maybe one day we will all be drivingvehicles and using equipment that runs off of simple renewable resources such as electricity,water, and or even cooking oil.
