Diesel Engines Vs. Gasoline Engines

Gas engines are mainly used by the individual in personal vehicles whereas diesels are very popular in the commercial and industrial fields. Diesel engines are used by the navy in their ships and by the army in their tanks and big trucks. Some of the main reasons for choosing this engine are

Thesis Statement: Internal combustion engines are very important to today 's society, the four stroke engine is the most popular and important due to it long history of achievement and durability.

Although internal combustion engines are what powers most cars on the road today, its efficiency is very low. An average combustion engine today is only able to convert 20% of the thermal energy content of gasoline into doing mechanical work (3). Most of the energy is lost to heat which

Conventional wisdom was that diesel was the only way to deliver significant fuel economy improvements in trucks. However, the growing emergence of direct-injected and turbocharged gasoline engines have made the fuel economy difference between gas and diesel engines much smaller than before. Seredynski said that regardless of fuel, the end goal is the same: maximum power from the minimum amount of fuel. The Ram 1500 Eco Diesel is the current full size pickup mileage champ at 20/28 mpg in EPA testing, but Ford's new 2.7L Eco Boost V-6 gas engine is likely not be far behind. Another enabling technology that has increased economy on both gas and diesel engines are transmissions with much higher gear counts, with six speeds now considered the

2. “ Because of their efficiency and durability, diesel engines have become the standard in powering trucks and buses. Other heavy vehicles and mobile equipment, including bulldozers and cranes, are also powered by diesel engines, as are many commercial boats, and some passenger cars and trucks. Diesel technicians handle many kinds of repairs. They may work on a vehicle’s electrical system, make major engine repairs, or retrofit exhaust systems with emission control systems to comply with pollution regulations. Diesel engine maintenance and repair is becoming more complex as engines and other components use more electronic systems to control their operation. For example, fuel injection and engine timing systems rely

and the average mpg of a gas car is 25 mpg. Also the average mpg

The first production electric cars were produced around the early 1900s and they were tremendously more popular than cars with gasoline engines. They eventually died out in the 1920s because of the decrease in cost of the gasoline engine. Even though electric cars faded away in the 1920’s they are making a comeback now due to the many benefits of an electric car over the traditional gasoline engine. Because of the rapid evolution of the electric car raises concern on the future of the gasoline engine, also the rise in popularity of the electric car because of environmental and other reasons. The future of electric cars will negatively affect the longevity of the gasoline engine because of the advancement of technology (or the area of) in

Gas engines versus diesel engines has got to be one of the biggest controversial topics in the automotive world. People have been arguing which is better for years upon years, and it is time to finally come to a conclusion. Anyone can probably notice that in almost every family there is a certain vehicle preference based off of the engine that runs them, but the term vehicle is extremely broad. To be more specific, especially in the southern part of the United States, those families have specific truck engines that they prefer. Either a person drives a truck for work or they drive a truck because they love them. Either way, nearly everyone in most of the United States has at least one truck in their family because they are just simply work horses. It’s also a huge part of the culture in the south to have a truck. Just about every boy and even a lot of girls want their first vehicle to be a truck. A pickup is one of the most reliable tools someone can own. Nearly every pickup enthusiast or working individual needs a gas or diesel truck, and the better choice is a diesel truck.

Initial purchasing costs of gas over diesel powered vehicles is usually a large factor that consumers take into account when purchasing a vehicle. Research has shown that on average, a diesel version versus gasoline version of the same vehicle, is $5,045 more than the gasoline version. (Vincentric, 2012) Consumers buying on a budget have to take these factors into consideration, which generally means that in more consumer-oriented cars and SUVs, the gasoline version sells much better than the diesel. Common reasons for this is that usually consumers associate diesel engines with the loud, smoke-blowing pickup trucks that smoke out an entire intersection. So people in the market for a vehicle that haven’t done their homework on the diesel powered version are more than likely to pick the gasoline version.

The developments of electric cars are associated with numerous benefits to the different stakeholders who are involved in their operations. Among the benefits include the environmental benefits where the use of electric cars has eliminated emission of dangerous gases that are emitted by fuel based cars. The use of electric cars also has numerous health benefits to the public as some of the gases that are realized by fuel based cars are feared to be dangerous to the human health. Wolf, Ingo et al, also explains that electric cars are economical in the long run as the cost of electricity is low than the fuel and gas prices that changes with time (269) . Due to the ease of optimizing electric cars in comparison to fuel cars, the cars are also considered to be much safer to their users in comparison to fuel cars. During accidents, some of the fuel based cars explode as the fuels are flammable.

The diesel engine was originally designed to be used in commercial areas, but times have since changed from its invention in 1893. (Jääskeläinen, 2013) In modern times, more and more car manufacturers are using diesel engines in not only trucks, but also cars. Since there have been improvements in the automotive field, and a drop in the fuel prices, more people are turning to diesel powered engines, even in smaller vehicles. Diesel releases fewer pollutants and produces a higher fuel economy, more power is harvested from diesel fuel, and the performance of diesel engines is higher than its competitor.

German engineer, Rudolf Diesel, built his first prototype engine in 1893. His engine was different than a regular gas engine (The Dirty Truth About Clean Diesel). The diesel engines required no spark plugs to ignite the fuel injected into each cylinder. Pressure and high temperatures cause it to combust spontaneously. Diesel engines ran on a grade of fuel far less flammable than gasoline. Diesels became the workhorse of the twentieth century. Today, many diesel engine manufacturers in the US are being required to regulate the emissions on their product. Multiple government

Are diesels better than gasoline engines? A significant segment of the consumer market thinks so, especially in Europe where such engines compose nearly half the vehicles purchased.

* Both kinds of engines depend on internal combustion for power. A diesel engine creates combustion by injecting compressed air into the engine. The compression causes the air to heat to about 1,000 degrees F, which ignites the diesel fuel. In a gasoline engine, gasoline is ignited by an electrical spark.

The world we live in is surrounded by diesel engines. They are on the freeways, railways, airways, and are one of the leading electricity producers in the world. They are also becoming more popular in automobiles. These engines are efficient and reliable and they are getting very sophisticated. However, the physics behind these engines has not changed.
