- Introduction A four stroke or four cycle engine is an engine operating on the principle of internal combustion, in which pistons (one per cylinder in multi-cylinder engines) completes four separate strokes for each thermodynamic cycle, which is accomplished over two consecutive revolutions of the engine’s crankshaft.

These four strokes are: the Intake stroke, the Compression stroke, the Power stroke and the Exhaust stroke. The sectional diagrams below illustrate these four strokes in a single-cylinder engine; the curved red arrows represent the direction of rotation of the camshafts (small arrows) and the engine’s crankshaft (larger arrows). The ...

Introduction

When the word “fluid” is mentioned in everyday language, many think that it simply refers to liquids. However, in the world of physics, the term fluid has an entirely different meaning. It denotes any liquid or gas that has the ability to adjust or conform to the shape of the container in which is it being held. Fluid mechanics refers to the study of fluids in motion and at rest. Fluid mechanics is usually divided into two subsections. The first subsection is referred to as fluid statics. This is primarily concerned with studying those fluids are stationary or static. ...

1.0 Lab 1: Heating Value Measurements: Solid and Liquid Fuels with a Bomb Calorimeter 1.1 Introduction Measurements of heating values can be derived for both solid and liquid combustible fuels using an Oxygen Bomb Calorimeter. The calorimeter measures heat. Heat is not the same thing as temperature. The heat of combustion is called the calorific value. The calorific value is “:the number of heat units liberated by a unit mass of a sample when burned with oxygen in an enclosure of constant volume” (Introduction 2007). The experiment uses the 6100 Bomb Calorimeter. The definition of calorific value in a bomb calorimeter ...
