. 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

Fluid mechanics is the branch of physics that studies fluids (liquids‚ gases‚ and plasmas) and the forces on them. Fluid mechanics can be divided into 1) fluid statics‚ the study of fluids at rest; 2) fluid kinematics‚ the study of fluids in motion; 3) fluid dynamics‚ the study of the effect of forces on fluid motion. Fluid Mechanics Overview Fluid is a substance that is capable of flowing. It has no definite shape of its own. It assumes the shape of its container. Liquids and gases are

Gasoline vs. Diesel 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. At first glance‚ someone who doesn’t know much about either of the two engines might ask‚ “What’s the difference?” To the untrained eye they might look exactly alike‚ but don’t judge the engine by its exterior look. Gas engines are mainly used by the individual

A Literary Analysis of “Popular Mechanics” In the short story‚ “Popular Mechanics”‚ Raymond Carver blends a variety of literary elements which amplify the tone. The tone is both threatening and somber‚ switching back and forth until finally fusing together in the final paragraphs. Syntax plays perhaps the most significant role in the flow of the story. The syntax is particularly interesting because the conversation between the two main characters has absolutely no quotation marks. The lack

Elastic Fracture Mechanics (LEFM). In this criterion‚ the two fracture parameters take account of the deviation of the stress to failure from the stress calculated pursuant to LEFM principles. These parameters have to be calculated earlier in pretests known as base line tests to be conducted under identical conditions of the material. It was possible neither to find 48 the failure stress of pressure vessels by means of the fracture parameter obtained from fracture mechanics specimen nor to

manner compared to overhead valves (OHV) and pushrods. Function-It carries inlet and exhaust valve. Fresh charge is admitted through inlet valve and burnt gases are exhausted from exhaust valve. In case of petrol engine‚ a spark plug and in case of diesel engine‚ an injector is also mounted on cylinder head. 3.
