Competition Vehicle Based Intake Manifold Design, Joshua N. Matiash
Competition Vehicle Based Intake Manifold Design, Joshua N. Matiash
Dissertations, Master's Theses and Master's Reports
A competitive vehicle in Formula SAE needs to be easy for unskilled drivers to extract the maximum performance from. This requires a predictable and manageable torque curve. This report details the development of an intake manifold for a Formula SAE car from a vehicle-based approach to produce this manageable and predictable torque. The current vehicle was instrumented and driven on a representative track to determine the usage of available torque. Based on these findings an ideal torque curve was chosen that favored increased torque at upper engine speed ranges and decreased torque at lower engine speed ranges. A 1-D engine …
Design And Fabrication Of A Suspension Rig, Abhijith Geo Philip
Design And Fabrication Of A Suspension Rig, Abhijith Geo Philip
Dissertations, Master's Theses and Master's Reports
Owing to its placement under the vehicle body, the suspension system is one of the parts of the vehicle which are difficult to comprehend completely, albeit being a vital component. For demonstrating the working of a suspension system, a physical model in which one can actually see the movement of all the components would be a great tool. A Mustang II independent front suspension system was purchased from Heidts Engineering Performance and a rig that can emulate some of the real world situations of vehicle suspension action was designed and fabricated. All the components are accessible and conditions like bounce, …
Restraint System Design And Evaluation For Military Specific Applications, Sebastian Karwaczynski
Restraint System Design And Evaluation For Military Specific Applications, Sebastian Karwaczynski
Dissertations, Master's Theses and Master's Reports
This research focuses on designing an optimal restraint system for usage in a military vehicle applications. The designed restraint system must accommodate a wide range of DHM’s and ATD’s with and without PPE such as: helmet, boots, and body armor. The evaluation of the restraint systems were conducted in a simulated vehicle environment, which was utilized to downselect the ideal restraint system for this program.
In December of 2011 the OCP TECD program was formulated to increase occupant protection. To do this, 3D computer models were created to accommodate the entire Soldier population in the Army. These models included the …
Design Of Real-Time Combustion Feedback System And Experimental Study Of An Rcci Engine For Control, Jayant Kumar Arora
Design Of Real-Time Combustion Feedback System And Experimental Study Of An Rcci Engine For Control, Jayant Kumar Arora
Dissertations, Master's Theses and Master's Reports
Premixed compression ignition (PCI) technologies offer high efficiency and low emissions but are usually confined by limited operation range as well as high pressure rise and heat release rate. In this work, a more recently developed PCI mode is explored where in-cylinder blending of two fuels with different auto-ignition characteristics (diesel and gasoline) is utilized to create reactivity stratification such that heat release rate and combustion timing can be controlled. This mode has been defined as Reactivity Controlled Compression Ignition (RCCI).
As part of this thesis, the main aim is to study various parameters that can be used to control …

Experimental Study, Modelling And Controller Design For An Rcci Engine, Naga Nithin Teja Kondipati
Dissertations, Master's Theses and Master's Reports
Low Temperature Combustion (LTC) has got widespread attention over the past two decades in the field of Automotive Research and Development due to it’s potential for achieving higher efficiencies with near-zero engine out NOx and soot emissions. Among all the LTC strategies Reactivity controlled compression ignition (RCCI) has shown the most promising results due to it’s precise control over combustion phasing and heat release rate. However, RCCI being a dual-fuel stratified combustion, precise control over the injection timing of direct injected fuel and in-cylinder fuel reactivity of the mixture needs to be controlled effectively in order to achieve gross indicated …
An Experimental Investigation Of The Effect Of Temperature And Space Velocity On The Performance Of A Cu-Zeolite Flow-Through Scr And A Scr Catalyst On A Dpf With And Without Pm Loading, Vaibhav Kadam
Dissertations, Master's Theses and Master's Reports
Abstract The heavy-duty diesel (HDD) engines use the diesel oxidation catalyst (DOC), catalyzed particulate filter (CPF) and urea injection based selective catalytic reduction (SCR) systems in sequential combination, to meet the US EPA 2010 PM and NOₓ emission standards. The SCR along with a NH₃ slip control catalyst (AMOX) offer NOₓ reduction >90 % with NH₃ slipHowever, there is a strong desire to further improve the NOₓ reduction performance of such systems, to meet the California Optional Low NOₓ Standard implemented since 2015. Integrating SCR functionality into a diesel particulate filter (DPF), by coating the SCR catalyst on the DPF, …

Design, Fabrication And Analysis Of An Auxiliary Power Unit On A Heavy-Duty Truck To Power The Hvac Systems Of The Truck During Driver Off-Duty Conditions, Rohan Milind Kalurkar
Dissertations, Master's Theses and Master's Reports
Currently, one of the biggest challenges the world is facing is energy insufficiency. One of the contributors to energy consumption in United States are the idling semi-trailer trucks. In May 2001, President Bush issued The National Energy Policy in which he directed The Environmental Protection Agency (EPA) and Department of Transportation (DOT) to reduce the idling of trucks. This was done in order to reduce energy consumption by lowering fuel consumption and emissions coming out of semi-trailer trucks in the United States of America.
This project deals with the efforts of installing an Auxiliary Power Unit (APU) as a device …
Integration And Testing Of An Advanced Conformable Cng Tank In A Full-Sized Light-Duty Pickup, Abayomi Famuyiwa
Integration And Testing Of An Advanced Conformable Cng Tank In A Full-Sized Light-Duty Pickup, Abayomi Famuyiwa
Dissertations, Master's Theses and Master's Reports
Michigan Technological University is collaborating with Southwestern Energy and REL Inc. to develop and integrate a compressed natural gas (CNG) matrix tank that enables efficient packaging, increases range, and reduced cost for CNG vehicle applications. The vehicle being used in this project is a light-duty pickup truck to take advantage of the open space underneath the body and bed of the vehicle. With today’s cylindrical CNG tanks consuming cargo space, a solution is to develop a tank capable of being shaping to the underbody of the truck to free cargo space. University faculty and graduate students utilizes Finite Element Analysis …
