Book excerpt: This thesis deals with thermal analysis in internal combustion engine. The objective of this thesis is to develop finite element model of combustion chamber for thermal analysis, to obtain the temperature distribution in combustion chamber and its surrounding component, and to determine localized temperature region in the engine.Finite element method (FEM) was employed to develop computational model to analyze the temperature distribution in the engine components and to identify the critical temperature in the components. Computational domain consists of combustion chamber as major part and its surrounding components such as valves, and exhaust port and water jacket. Two types of combustion process were modelled: Spark ignition engine and compression ignition engine. 2-dimensional (2D) simplified models was developed using general-purpose FE code, ALGOR. The element type was 2D element. Material properties were taken from ALGOR library. Heat convection due to the presence of water was defined by convection coefficient. Thermal load due to combustion was defined to all nodes of combustion chamber. The finite element models were analyzed using the thermal transient heat transfer analysis. The finite element model was validated by comparing the maximum temperature at the piston surface with the published result. The results were found to be agreeable. The computed results indicate that the exhaust part may reach the highest maximum temperature in the engine after combustion occurred. In SI engine, the critical component in thermal effect is the cylinder head and for the CI engine is at the piston bowl. Furthermore, the material used to construct the engine part strongly influences the temperature distribution in the engine. Therefore, the performance of the engine at very high temperature can be improved by changing material and design of component. From the analysis, the capability of diesel engine to resist thermal contact is higher compare to gasoline engine because of using higher thermal resistance material with suitable shape and geometry design.

Download or read book Thermal Management in Automotive Applications written by T Yomi Obidi and published by SAE International. This book was released on 2015-03-30 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: With new and more stringent standards addressing emission reduction and fuel economy, the importance of a well-developed engine thermal management system becomes even greater. With about 30% of the fuel intake energy dissipated through the cooling system and another 30% through the exhaust system, it is to be expected that serious research has been dedicated to this field. Thermal Management in Automotive Applications, edited by Dr. T. Yomi Obidi, brings together a focused collection of SAE technical papers on the subject. It offers insights into how thermal management impacts the efficiency of engines in heavy vehicles, the effects of better coolant flow control, and the use of smart thermostat and next-generation cooling pumps. It also provides an in-depth analysis of the possible gains in optimum warm-up sequence and thermal management on a small gasoline engine. With continuously increasing gadgetry in modern vehicles, the average temperature in the engine compartment has seen significant increase. It is important to be able to divert the heat away from passengers as well as from some components that may be negatively impacted by excessive temperatures. Thermal Management in Automotive Applications points out solutions to this challenge, including material and design options.

This book was released on 2019-01-19 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crew exploration vehicle (CEV) service module (SM) main engine plume heating is analyzed using multiple numerical tools. The chemical equilibrium compositions and applications (CEA) code is used to compute the flow field inside the engine nozzle. The plume expansion into ambient atmosphere is simulated using an axisymmetric space-time conservation element and solution element (CE/SE) Euler code, a computational fluid dynamics (CFD) software. The thermal analysis including both convection and radiation heat transfers from the hot gas inside the engine nozzle and gas radiation from the plume is performed using Thermal Desktop. Three SM configurations, Lockheed Martin (LM) designed 604, 605, and 606 configurations, are considered. Design of multilayer insulation (MLI) for the stowed solar arrays, which is subject to plume heating from the main engine, among the passive thermal control system (PTCS), are proposed and validated.

Download or read book Thermal Analysis and Cold Start Performance of Automotive Emission Systems written by Sumit Kumar and published by . This book was released on 2002 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Automotive exhaust emission regulations are becoming stricter due to increasing awareness of the hazardous effects of exhaust emissions. The main challenge to comply with the EPA regulations is to reduce the emissions during cold start, because catalytic converters are ineffective until they reach a 'light-off' temperature - the temperature at which the converter starts reducing 50 % of emissions. A thermal model of a catalytic converter is presented which reduces the light-off time and significantly reduces the concentration of exhaust gas emissions. This thesis describes a numerical model of the catalytic converter, which is used to predict catalytic converter performance during cold-starts. Simulations were carried out using a finite element software - Abaqus, to study the catalytic converter performance at various temperatures. After analyzing thermal models for both - uniform heat distribution and cost effectiveness, a heat source of 90 W was chosen for a three-heater configuration (30 W each) to pre-heat the converter. A reduction in the concentration of emissions by a factor of 4 to 6 were recorded as a result of vehicle simulation with this thermally designed catalytic converter. ADVISOR (Advanced Vehicle Simulator), a vehicle simulator, was used to calculate 'engine-out emissions'"--Leaf iii.
