PERFORMANCE IMPROVEMENT OF DIESEL ENGINES BY STRESS REDUCTION USING A FOUR CYLINDER DIESEL ENGINE AS MODEL. A RESEARCH PROJECT MATERIAL ON MECHANICAL ENGINEERING
1.1 Background of Study
To illustrate a background to the context and course of discourse, we will be giving an over view of four cylinder diesel engine. The four cylinder diesel engine as implied by its nomenclature is a compression ignition engine which generates power required to drive machines through intermediate functioning of the flywheel. The major difference between it and the other four stroke diesel engines is the number of cylinders. Whereas the four cylinder diesel engine is operationally functional upon the strength of four cylinders working simultaneously under an idea condition to generate the necessary power required to drive any other machine, the one, two, three, six, twelve, sixteen cylinder diesel engines operate upon the strength of the number of cylinders. Under a normal circumstance, it is operationally expected that the four cylinder engine generates more power for work than engines with lesser number cylinder engine.
Diesel engines occupy a large fraction of the quadrant of machines in engineering when it comes to subject of use and application. Diesel engines find a major application as a prime mover (a source via which other machines are driven). On board-ship the marine diesel engines serve as the prime movers, converting mechanical energy from burning fuel into thrust energy in the propeller so as to propel the vessel. Improving on the performance of the engine affects the amount of thrust generated to overcome ship resistance. This entire circle if properly managed reduces cost of running a vessel for desired purposes.
1.2 Problem Statement
The functional performance of diesel engines when evaluated has always been a function of predominant failure which are traceable to the subjects of operational design and maintenance. Any attempt to improve engine performance under these subjects will be a plus to the use and application of diesel engines even in a long time to come.
1.3 The Aim of this Work
The aim of this work is to improve on the performance of diesel engines by stress reduction using a four cylinder diesel engine as model.
