. How Do Diesel Engines Work? The basic difference between a diesel engine and a gasoline engine is that in a diesel engine‚ the fuel is sprayed into the combustion chambers through fuel injector nozzles just when the air in each chamber has been placed under such great pressure that it’s hot enough to ignite the fuel spontaneously. Following is a step-by-step view of what happens when you start up a diesel-powered vehicle. 1. You turn the key in the ignition. Then you wait until the engine

II. MECHANICAL STRUCTURE Both being internal combustion type diesel and gasoline engines can be considered as similar. Simply‚ both engines converts chemical energy into mechanical one by burning fuel. In combustion engines the combustion (explosion of fuel) occurs at combustion chamber with ‚ generally‚ help of oxidizer (air‚ another fluid‚ etc.). The output‚ high heat and pressure of the burning process is transfered to other components of the engines which expose pressure as a mechanical energy

Have you ever wondered how hard it would be to become an automotive mechanic? Automotive mechanics is a very hard work field to get into‚ and helps you to save money in the long run. Within the field‚ you work very hard and work very long hours. Being an automotive mechanic is a good choice because of job security‚ pay‚ and not much schooling is required. The main reason why I think people go into automotive mechanics is because you don’t need much schooling; therefore‚ it’s an easy work force to

The History and Development of the Common Rail Diesel Engine To be honest‚ I don’t really know too much about the history or the functions and operations of a diesel engine‚ but I am excited about learning more about it through this assignment and when we go to study it in detail during class. History The evolution of Diesel injections actually began from the invention of the gasoline engine. The gasoline engine wasn’t very efficient‚ even worse than the steam

Does a diesel vehicle save you money? Not always‚ but diesels get great fuel mileage‚ twenty to thirty percent20-30% better than a gas. Aa gas powered pickup truck is lucky to get better than twelve12 or thirteen miles per gallon‚13 mpg while the same model diesel will get eighteen18 miles per gallonmpg or better. Tthis is due to the chemical properties of gasoline and diesel. A diesel has more potential energy in it than gas does so it takes less fuel to get the same amount of useable energy.

DIESEL MECHANIC Growing up in Odessa I remember waking up in the mornings‚ going outside and taking a deep beath. The smell of West Texas air is a mixture of Diesel‚ cattle‚ oil and dirt. These are a few of the scents that I cannot see myself living without. In the mornings I would gather my toy trucks and toy tools to go play in the backyard. I would spend hours outside taking things apart and putting them back together. My father would even let me help him repair or take a look at our vehicles

Welly 1 Quinn Welly Fr. Hudgin Mythology 4 December 2013 The Diesel Engine: Making a Comeback The diesel engine has provided the world with cheap and efficient power for over one hundred years. The invention was first thought up by Rudolph Diesel in 1892. He wanted to create an engine that would be more efficient than the steam engine‚ which was only 12% efficient. He filed for a patent in Germany in February of 1892. He was granted a patent for a “Working Method and Design for Combustion

Fuel injection in diesel engines [edit] Mechanical and electronic injection Older engines make use of a mechanical fuel pump and valve assembly which is driven by the engine crankshaft‚ usually via the timing belt or chain. These engines use simple injectors which are basically very precise spring-loaded valves which will open and close at a specific fuel pressure. The pump assembly consists of a pump which pressurizes the fuel‚ and a disc-shaped valve which rotates at half crankshaft speed
