Performance Results Of Using Waste Vegetable Oil Based Biodiesel Fuel In A Turboshaft Gas Turboshaft Engine, 2018 Southern Illinois University Carbondale
Performance Results Of Using Waste Vegetable Oil Based Biodiesel Fuel In A Turboshaft Gas Turboshaft Engine, Donald Bartlett 5218591, Blaine M. Heisner
Journal of Applied Sciences and Arts
Biodiesel is a renewable fuel product made from triglycerides with properties similar to petroleum-based fuel. It is blended with various petroleum fractions to produce automotive and transportation fuels and is not typically utilized as a standalone fuel. Biodiesel can be manufactured from various feedstock including straight vegetable oils (SVO), waste vegetable oils (WVO), and animal fats. Although most U.S. biodiesel is made from SVO, using WVO feedstock is a much cheaper option. As biodiesel fuel offers certain advantages over petroleum based fuels, the aviation industry has gradually advanced the use of the fuel in gas turbine engines. However, increased ...
Effects Of Air-Fuel Ratio And Operating Conditions On Particle Emissions From A Small Diesel Engine, 2018 Bucknell University
Effects Of Air-Fuel Ratio And Operating Conditions On Particle Emissions From A Small Diesel Engine, Odinmma John-Paul Ofili
Automotive engineers typically increase the air-fuel ratio (AFR) of an engine to control the amount of smoke emitted, but it not quite known how this process affects particulate number (PN). In the work presented, AFR was independently varied to study its effects on PN. It was found that increasing the AFR reduced the concentrations of larger particles from 108 #/cm3 to 106 #/cm3 which is an effect observable as a reduction in smoke. However, the same increases in AFR only resulted in an energy specific PN change from 1015 #/kWh to 1014 #/kWh. The ...
Characterization Of Rotary Bell Atomizers Through Image Analysis Techniques, 2018 University of Kentucky
Characterization Of Rotary Bell Atomizers Through Image Analysis Techniques, Jacob E. Wilson
Theses and Dissertations--Mechanical Engineering
Three methods were developed to better understand and characterize the near-field dynamic processes of rotary bell atomization. The methods were developed with the goal of possible integration into industry to identify equipment changes through changes in the primary atomization of the bell. The first technique utilized high-speed imaging to capture qualitative ligament breakup and, in combination with a developed image processing technique and PIV software, was able to gain statistical size and velocity information about both ligaments and droplets in the image data. A second technique, using an Nd:YAG laser with an optical filter, was used to capture size ...

Increasing restrictions on the emitted exhaust emissions in diesel engines are becoming a more challenging task than in previous years. An electronic common rail fuel injection system and a port fuel injection (PFI) system were developed for an experimental engine to research dual fuel combustion. The experimental research was conducted at 1500 rpm and 4, 5, and 6 bar indicated mean effective pressure (IMEP). n-Butanol was port fuel injected at a 60% by mass fraction coupled with direct injection (DI) of three fuels, including ultra-low sulfur diesel (ULSD RCCI), a 50-50 wt-% blend of ULSD and butanol (ULSD-Bu RCCI), and ...
Application Of Real Field Connected Vehicle Data For Aggressive Driving Identification On Horizontal Curves, 2017 San Diego State University
Application Of Real Field Connected Vehicle Data For Aggressive Driving Identification On Horizontal Curves, Arash Jahangiri, Vincent Berardi, Sahar Ghanipoor Machiani
Psychology Faculty Articles and Research
The emerging technology of connected vehicles generates a vast amount of data that could be used to enhance roadway safety. In this paper, we focused on safety applications of a real field connected vehicle data on a horizontal curve. The database contains connected vehicle data that were collected on public roads in Ann Arbor, Michigan with instrumented vehicles. Horizontal curve negotiations are associated with a great number of accidents, which are mainly attributed to driving errors. Aggressive/risky driving is a contributing factor to the high rate of crashes on horizontal curves. Using basic safety message data in connected vehicle ...

What Happens To Nox Emissions Of Vw Diesel Cars When Water/Methanol Injection Is Used?, 2017 Southern Illinois University Carbondale
What Happens To Nox Emissions Of Vw Diesel Cars When Water/Methanol Injection Is Used?, Andrew Croxell
ASA Multidisciplinary Research Symposium
Volkswagen has come under fire for their "Clean Diesel" automobiles that were found to emit too much NOx (Oxides of Nitrogen) when driven on the street. Since NOx is created by high temperature combustion events, the addition of a water/methanol injection system was tested on a VW diesel vehicle to identify if it could cool combustion temperatures and thus reduce NOx to an acceptable specification.

Distributed Control System For Parallel-Connected Dc Boost Converters, Steven Goldsmith
Michigan Tech Patents
The disclosed invention is a distributed control system for operating a DC bus fed by disparate DC power sources that service a known or unknown load. The voltage sources vary in v-i characteristics and have time-varying, maximum supply capacities. Each source is connected to the bus via a boost converter, which may have different dynamic characteristics and power transfer capacities, but are controlled through PWM. The invention tracks the time-varying power sources and apportions their power contribution while maintaining the DC bus voltage within the specifications. A central digital controller solves the steady-state system for the optimal duty cycle settings ...
Design, Synthesis And Sustainable Applications Of Animal Protein-Based Thermoset Polymers And Covalent Organic Frameworks, Xiaoyan Yu
Extensive research has been undertaken in recent times on finding suitable, alternative, non-feed and non-fertilizer applications for proteinaceous materials in the animal rendering industry. In this regard, use of such proteins to derive plastics, especially thermoplastics and derived composites, has emerged as a potentially acceptable choice. However, the widespread use of such proteins for aforementioned applications is limited by their poor mechanical properties, high moisture absorption and their inherent odor. In this study, we have engineered, for the first time, high-strength, toughened thermoset polymers from proteinaceous materials obtained from the rendering industry so that they can be employed in high ...

Autonomous Speed Control For Kia Optima, 2017 Kennesaw State University
Autonomous Speed Control For Kia Optima, Andrew J. Combs, Kyle Fugatt, Kevin Mcfall
The Kennesaw Journal of Undergraduate Research
The standard method for speed control is the cruise control system built into most modern vehicles. These systems employ a PID controller which actuates the accelerator thus, in turn, maintains the desired vehicle speed. The main drawback of such a system is that typically the cruise control will only engage above 25 mph. The goal of this paper is to describe a system which we used to control vehicle speed from a stop to any desired speed using an Arduino microcontroller and a CAN BUS shield, from where autonomous features can be built upon. With this system, we were able ...

Formula Sae Power Distribution Controller, 2017 California Polytechnic State University, San Luis Obispo
Formula Sae Power Distribution Controller, Daniel Baron
The Power Distribution Controller senior project aims to replace the current Power Distribution Module (PDM) on Cal Poly’s Formula SAE internal combustion vehicle with a more advanced, configurable, and reliable system. The Power Distribution Controller is a MOSFET based system that can be controlled through either controller area network or a parallel interface to distribute and control power from the vehicle’s battery to the several electrical devices on the car. The Power Distribution Controller also collects output voltage and current data, and communicates this data to the vehicle’s data logger. This will allow engineers to troubleshoot electrical ...
