My dad and I have always argued about which type of engine was better. My dad thinks that gas engines are the best. I think that diesel engines are the best. The diesel engine has a better design for all around usability than a gas engines. First, the weight of diesel engines are on average is 1,100 pounds. The engine has to be built stronger, because the compression ratio is a lot higher. As it runs, the pistons compress air to an extreme heat, and as it reaches top dead center, the fuel is injected into the combustion chamber. The fuel being injected directly in the hot air results in a highly destructive explosion that drives the piston down creating power. In addition, it makes the iconic diesel knock sound. Gas engines are built weaker because the compression ratio is lower. If a gas engine had the same compression ratio as a diesel, it would not even start to run because it would blow up at idle. The gasoline engine has spark plugs that ignites the fuel. They don’t need to compress air to an extreme heat like the diesels do. As the pistons travel up, the air-fuel mixture is introduced into the combustion chamber. The air fuel mixture just sits there for a split second, and then the plug sparks and ignites the fuel. This is why the gasoline engines are lighter than diesel. In addition, the weight of a diesel engine also effects the usable power band. The power band is at what rotation per minute (RPM) the power kicks in. RPM is how fast the crankshaft is spinning in
It may be a diesel engine, but it does not feature the rocking or all of the noise that is associated with typical diesel engines. This is due to the Centrifugal Pendulum Vibration Absorber
You’re in the market for a new truck; you have an idea about what you want but not quite sure if you want a gasoline or a diesel engine. Well, gas and diesel engines are very similar yet different in quite a few ways.
When it comes to the environmental impact that gas and diesel engines have. It turns out that gasoline is more unstable than diesel, not because of what its base consists of, but because of the additives it contains. In addition, vehicles that use diesel tend to be more fuel-efficient and produce less greenhouse gases. Diesel is more environmentally friendly. The United States has what is considered to be the dirtiest diesel, but as of June 1, 2010 this is going to be different. U.S. diesel fuel has a lower measure of ignition quality. This means that when it is cold outside, ignition performance is poor and can result in higher emissions. This is why you see truck drivers idling their trucks all night long in cold weather rather than risk a troublesome start in the mornings. But, the sulfur in the diesel that is emitted during cold ignitions and long engine idling is still harmful to the environment because the sulfurs prevent the control of diesel particulate emissions through diesel particulate filters. This is changing, though, since new advanced technologies such as nitrogen oxide absorbers are being developed to reduce these emissions. As for gasoline, it is the non-aliphatic hydrocarbons as well as carcinogenic additives
1. Have you ever wondered how the things you buy get delivered to the stores? Semis, planes, trains, and sometimes boats. The majority of them run on diesel, because diesel is more efficient than a gasoline engine. With the number of diesels on the road everyday there is a high demand for mechanics that are properly trained to work on them. You have to be able to leave home on a moment’s notice to travel and repair trucks on the road. Being a diesel mechanic is very stressful and you never know what you will be working on day to day.
A. A gas engine uses spark to ignite gasoline while a diesel engine uses compressed air to ignite the diesel fuel.
The F-250 weighs 5,648 lbs., GMC and Chevy weigh 4,184 lbs., and the lightest diesel is the Dodge Ram which weighs 3,100 lbs. The heaviest part, and arguably the most important part, of a truck is the engine. The F-250's engine is a 6.7 liter Power stroke. The Chevy and GMC diesel engines are also 6.7 liters Duramax. Dodge's engine is a 6.7 liter Cummins, which is considered the second strongest engine out there behind Ford. Ford's engine contains a class exclusive single sequential turbocharger, which sets apart Ford from the other makers in engine
The performance of a diesel truck and a gas burner truck are very different, but either one can be advantageous depending on its use. The horsepower of the diesel truck averages around 360, but can easily be modified with plug and go tuners that can increase HP to over 500 while the gas burner is at an all time high around 420 HP in the new v8 engines. The gasser may prevail in horsepower, but the diesel dominates in torque. The gasser tops out around 460 lb/ft while the diesel blows it away at 765 lb/ft. The towing capacity is the game changer for the diesel truck compared to the gasser. The gasser starts to struggle around 12,000 pounds at high RPMs, but the diesel is still running smoothly around 17,500 pounds. It is hard for the gasser’s towing power to beat the towing power of
First, let's talk about trucks. A six point six liter Chevy Duramax has four hundred forty five horsepower. A six point seven liter Powerstroke has four hundred forty horsepower. Duramaxes are stronger than Powerstrokes by five horsepower.
If you are on the pro-truck side of the argument then you are probably looking at it with more of a sense of adventure and discovery than a car, and you are most likely more focused on making memories with your time rather than nice physical things with your money. Yes, it is true that trucks do not have near as good gas mileage as more fuel-efficient cars however. they use that fuel for different things such as off-roading, towing trailers and pulling things. Trucks are often seen in more rural settings of the country and are used primarily to carry things such as trailers full of hay, or to do manual things like pulling a tractor out of mud. They are the ideal vehicle when you need raw power to get you out of a tough situation like when your car is buried so deep in mud that you can’t get to the frame.
There are many factors that need to considered when deciding between a diesel or gas pickup. One of which is the potential fuel economy. When looking at fuel economy, diesel pickups tend to get more miles to each gallon. But there are other things that need to be taken into consideration when thinking about fuel economy. Even though diesel will get better MPG the cost of fuel per gallon is usually more expensive than gasoline. I have only seen it where
In 1982 General motors introduced their first diesel engine for the pickup line. The engine manufacturer that GM partnered with was Detroit Diesel. Detroit Diesel was a good choice because Detriot Diesel had a reputable name for being reliable and well built. This was GM's first attempt at a reliable consumer diesel engine GM was not aiming for a top of the line performance diesel. This engine was a 6.2 liter naturally aspirated diesel engine, this combination engine was used from 1982-1993. The 6.2 series of diesel engine was used along with the 6.5 Turbo and non Turbo renditions of the 6.5. The 6.2 was completely discontinued in 1995 but was the building block for the 6.5 Engine. The 1993 series engine used all the same engine components but the bore was changed from 3.98 inches to 4.06 this increased horsepower and torque.
In conclusion, diesel engines are better than gasoline engines because they produce more power with less fuel and more life in a diesel engine than the gasoline engine. Finally, diesel engines are better because they are
Engineering: [a] diesel engine is an internal combustion engine in which the chemical energy of fuel is transformed into thermal energy of the cylinder charge, in consequence of the self-ignition and combustion of fuel in the engine cylinder after compression of the air charge in the cylinder (p1
In the application of Diesel propulsion system, it has advantages and disadvantages. The advantages are diesel propulsion is wellknown and wellunderstood and it is a dependable method of propulsion and supporting power. Engineers can easily operate the system and the training is familiar for them. Spare part and repairmen are available world wide. Diesel fuel also easy to obtain. Research and development to deal with primary and secondary method to reduce emission are being carried as a continuous programme. The disadvantages of this system are the diesel engines create
The four stroke engine is the now the most popular engine for cars. The first thing that happens is that the intake piston moves down drawing in a fresh charge fuel and air mixture into the cylinder. As the piston rises the intake valve is forced shut by increased cylinder pressure. As the piston rises, the intake valve is forced shut by the increased cylinder pressure. Flywheel momentum drives the piston upward, compressing the fuel and air mixture. At the top of the compression stroke, the spark plug fires, igniting the compressed fuel. As the fuel burns it expands driving the piston down. When the piston reaches the
