F in Exhaust Systems and How to Increase Efficiency - Assignment Example

The assessment method applied consists of three steps: 1) identification and ranking of the severity levels of the failure. 2) Identification and ranking of cause and effects of the potential failure modes, using the system of risk probability number (RPN). 3) Recommendation of additional safety measures and actions to be taken to improve the process safety, performance, and reliability. In this project, the process of risk assessment was carried out on a theoretical basis according to a well-laid down circulating and exhaust system.

The project was performed under set a timeline time and always faced the risk of losing the deadlines and facing unprepared challenges. It was anticipated that technical and skill-based problems would be faced especially in the design phase of the project. For instance, the calculation of complex engine efficiency equations and emission parameters, while balancing the various components of the exhaust would be quite hard. As explained in the methodology and design section, extra technical skills were required for individual components of the exhaust system to tackle both internal and external risks. Extra know-how was also required to get a better grasp of the vital principles and empirical formulas that govern automobiles. It, therefore, required impeccable management of time to avoid project delays. Furthermore, a keen focus needed to be paid to the list of required resources for the critical analysis of design parameters and for use in the failure modes and efficiency analysis.

Over the past decade or so, technological advancements have been happening at unprecedented rates with there being a change in the world on literally day-by-day steps. The automobile industry has been at the forefront of these advancements with the focus being on the efficient designs that improve the efficiency of the systems involved. A keen focus has also been accorded to the environmental impacts of these designs and how to reduce emissions from the same. A clear regulatory framework needs to be established by both the government and industries to control the emissions that negatively impact the health and safety of the population. Ullman (1997) noted that risk assessment is a vital stage during product design, development, and functioning.

Exhaust systems play an important role in engine performance as it is responsible for the removal of engine gases, a by-product of fuel combustion. Incidentally, the exhaust system comprises of a channeling tube that guides the gases out of the vehicle. The exhaust system is a multipurpose system as it deals with the exhaust gases, and noise from vibrations while leaving the tube effects of temperature changes. The aim of performance optimization can only be achieved through the balancing of physical and chemical effects especially for modern vehicles. Furthermore, environmental safeguards have been put in place to restrict and control emission rates and therefore the need for efficient design. In that regard, a catalytic converter must be used to not only minimize the toxicity of emissions but also improve fuel combustion (Bosch, 2001). High noise levels are controlled with the use of mufflers commonly referred to as silencers. These devices also reduce the vibration levels during operation.
