Internal Combustion Engine - Assignment Example Hence the internal combustion engine is the core component of any aircraft or car. The two-stroke and four-stroke engine are the most popular types of the internal combustion engine. It would be more feasible to first discuss the working of a four-stroke engine and then the working of a two-stroke engine, followed by its advantages and disadvantages. The cylinder is the core of the engine. The piston is a cylindrical piece of metal that moves up and down within the cylinder. There may be more than one cylinder present in different alignments based on the nature of the vehicle. The spark plug supplies the spark at regular intervals which is required to ignite the air/fuel mixture present inside the cylinder [2]. Two valves are present. The inlet valve allows the flow of air and fuel into the cylinder. The outlet valve allows the exhaust to flow out of the cylinder. The most important point is that both the valves must be closed during the process of compression and combustion so that the cylindrical chamber remains sealed [3]. The connecting rod is a piece of metal that connects the piston and crankshaft. Both the ends of the connecting rod can rotate so that its angle can be adjusted according to the motion of the piston and crankshaft. The up and down motion of the piston is converted into circular motion with the help of the crankshaft. The crankshaft is surrounded by a sump and engine oil gets collected in the sump.The four strokes include intake stroke, compression stroke, combustion stroke, and exhaust stroke [4]. Initially, the piston is at the top of the combustion chamber. First, the intake valve opens and this allows the piston to move down the cylindrical chamber. The descending motion of the piston allows the engine to take fuel (gasoline) and air inside the cylinder and the cylinder is gets filled with air and fuel. Air serves as an oxidizer for combustion. These events constitute the intake stroke.

Organizational Development in HRD Case Study Research Paper

Organizational Development in HRD Case Study - Research Paper Example She manages the situation stating that knowing more about the history and long term objectives of the firm is essential to answer their queries. The members are happy with the interaction as they have little knowledge about CQI. Stepchuck is taking advantage of the client’s ignorance by assigning Todd as an expert in CQI. Although Todd is genuine and wants to ensure openness, the president insists her to continue with the project. Now Todd has two options; either quit the job or take up the role of CQI expert. (1). At this juncture, the new job raises certain ethical dilemmas that Todd has to address immediately. Both ‘role ambiguity and role conflict’ are identified in the context, because as stated above â€Å"neither the client nor the OD practitioner is clear about the respective responsibilities† (p. 62). Moreover, the role ambiguity and role conflict will lead to subsequent dilemmas especially ‘coercion, value and goal conflict, and technical ineptness’. To illustrate, Todd does not want to jeopardize her honesty while working with the new project. At the same time she wants to help her client in some way, though CQI is not her cup of tea. The current dilemmas can be solely attributed to the unethical stance of Todd’s employer, because his intention is entirely different from that of the client firm and his staff Todd. Evidently, Stepchuck is running a profit driven business heeding little attention to the actual needs or interests of the clients. As the case indicates, if the client is not sure about the issues they want to address, an unethical professional like Stepchuck tends to take unfair advantage of the situation. Even if Todd undertakes the assignment, she may have to face challenges associated with the stated dilemmas. (2). The way Todd responded to the situation at the meeting seems reasonable. A professional like Todd does not want to disclose the
