Diesel Engine Heat engines are sometimes referred to as being motors. Actually‚ a motor converts one form of energy into useful work without the intentional production of heat‚ such as an electric motor. A device which burns fuel creating heat to perform work is a heat engine. Heat engines can be classified as external combustion‚ such as steam boiler‚ or internal combustion (IC). They can further be divided into the spark ignited (SI) engine or the compression ignited engine (CI). The compression

Piston Engines Picture a tube or cylinder that holds a snugly fitting plug. The plug is free to move back and forth within this tube‚ pushed by pressure from hot gases. A rod is mounted to the moving plug; it connects to a crankshaft‚ causing this shaft to rotate rapidly. A propeller sits at the end of this shaft‚ spinning within the air. Here‚ in outline‚ is the piston engine‚ which powered all airplanes until the advent of jet engines. Pistons in cylinders first saw use in steam engines. Scotland’s

A jet engine‚ like a rocket engine‚ is a reaction engine. It works by throwing mass in one direction and taking advantage of the reaction in the opposite direction. In the case of a jet engine‚ the engine burns fuel (like kerosene) with air from the atmosphere. The burning fuel heats and expands the air‚ and this hot air shoots out of the exhaust-end of the engine to create thrust. Most modern jet engines use a turbine to improve the efficiency of the engine and allow the engine to work at low speeds

Design/methodology/approach – This paper looks at the evolution of the “RICS Valuers Registration Scheme” and the potential impact it will have on raising the standards of valuations not just in the UK but worldwide. Findings – The RICS Standards require the valuer to undertake valuations in an appropriate and professional manner. The potential impact of the “RICS Valuers Registration Scheme” is that it will educate the profession and thus increase overall standards. Although

These include “finished goods” which are goods that have been completed and are awaiting sales. Manufacturers may also have “work in process inventory” made up of goods being manufactured but not yet completed. The third category of inventory is “raw materials‚” consisting of goods that are to

COMBUSTION ENGINES 6.1 Introduction Perhaps the best-known engine in the world is the reciprocating internal combustion (IC) engine. Virtually every person who has driven an automobile or pushed a power lawnmower has used one. By far the most widely used IC engine is the spark-ignition gasoline engine‚ which takes us to school and work and on pleasure jaunts. Although others had made significant contributions‚ Niklaus Otto is generally credited with the invention of the engine and with the
