"Electro Gyro-Cator" New Inertial Navigation System for Use in Automobiles

1983-02-01
830659
The Electro Gyro-Cator allows a driver to monitor his progress, plot and follow courses to a destination, select alternate routes, and drive more safely on unfamiliar roads or at night. Employing a sealed helium gas-rate gyro, the Electro Gyro-Cator offers visual display (CRT display) of a car's present location, direction and route, with overlay maps for fast, simple route selection and monitoring. The primary elements of the unit include trip and direction sensors, a 16-Bit central processing unit, a CRT display screen and a collection of transparent overlay maps fitted to the screen.

19-Color H2O Absorption Spectrometer Applied for Real-Time In-Cylinder Gas Thermometry in an HCCI Engine

2007-01-0188
1 An all fiber-optic sensor has been developed to measure H2O mole fraction and gas temperature in an HCCI engine. This absorption-spectroscopy-based sensor utilizes a broad wavelength (1320 to 1380 nm) source (supercontinua generated by a microchip laser) and a series of fiber Bragg gratings (19 gratings centered on unique water absorption peaks) to track the formation and temperature of combustion water vapor. The spectral coverage of the system promises improved measurement accuracy over two-line diode-laser based systems. Meanwhile, the simplicity of the fiber Bragg grating chromatic dispersion approach significantly reduces the data reduction time and cost relative to previous supercontinuum-based sensors. The data provided by the system is expected to enhance studies of the chemical kinetics which govern HCCI ignition as well as HCCI modeling efforts.

A student team from Minnesota State University, Mankato's Automotive Engineering Technology program entered the Clean Snowmobile Challenge 2000. A 1998 Polaris Indy Trail was converted to indirect fuel injection running on a computer controlled closed loop fuel system. Also chassis, exhaust, and hood design modifications were made. The snowmobile was designed to compete in eight events. These events included acceleration, emissions, hill climb, cold start, noise, fuel economy/range, handling/driveability, and static display. The snowmobile modifications involved every aspect of the snowmobile with special emphasis on emissions and noise. Laboratory testing led to the final design. This paper details the modifications and test results.

2 Stroke Fuel Injected Outboard Motor with Oxygen Sensor Feedback Control System

1997-10-27

This paper describes new 2 stroke fuel injected spark ignition outboard motor equipped with unique oxygen sensor feed back control system to assure constantly optimized air/fuel ratio. First, the general concept and the engineering target of commercial model are explained, and then the design and arrangement of oxygen sensor feedback fuel injection control system are described. Common automotive oxygen sensor is utilized in this system, and it is devised to overcome the problems inherent in 2-stroke engines. This paper also describes the controlled combustion system that enhances consistent and stable performance, and improves fuel efficiency. Applying these technologies, 40% less fuel consumption in cruise range was demonstrated by the comparative test with conventional fuel injected 2-stroke model.

2-Drive Motor Control Unit for Electric Power Steering

2017-03-28
2017-01-1485
The electric power steering (EPS) is increasing its number since there are many advantages compared to hydraulic power steering. The EPS saves fuel and eliminates hydraulic fluid. Also, it is more suitable to the cooperation control with the other vehicle components. The EPS is now expanding to the heavier vehicle with the advance in the power electronics. In order to meet customer's needs, such as down-sizing, lower failure rate and lower price, we have developed the new motor control unit (MCU) for the EPS. The motor and the electric control unit (ECU) were integrated for the better installation. We adopted new technologies of redundant 2-drive design for more safe EPS. “2-drive Motor Control technology” which consists of dual winding, two torque sensors and two inverter drive units. In our developed MCU, even if there is a failure in one of the drive unit, the assistance of the EPS can be maintained with the other drive unit.

20 Years of UNSW Australia's Sunswift Solar Car Team: A New Moment in the Sun, but Where to Next?

2015-01-0073
The Sunswift Solar Car project has been running at UNSW Australia in Sydney for 20 years as of 2015. It is an entirely student-run endeavour which revolves around the design and development of a solar/electric vehicle nominally designed to compete in the World Solar Challenge rally from Darwin to Adelaide every 2 years. The student cohort is drawn from a range of schools, disciplines and backgrounds, and the team has been increasingly successful and high-profile particularly in its second decade. The excellent level of hands-on training that the project provides to students is not rewarded with academic credit yet many of the alumni credit the project with launching their careers and ambitions. The team's world record-breaking latest vehicle, eVe, is the fifth constructed and presents a radical departure from previous cars in that it carries a passenger in a conventional layout and is based around a road-going sports car.

2002 Joint EPA/SAE-ESSC Workshop Environmental Systems Decision Making

2003-03-03
2003-01-0549
This is a report of a workshop held in mid-August of 2002 at Northwestern University, Evanston, Illinois, to explore what it takes to make a decision regarding environmental systems in the US. The participants in the workshop represented federal government, industry, non-governmental organizations and academia. During the two and a half day workshop, discussions were held on the policy drivers, the strategies and tactics (through a SWOT analysis), the decisions the automotive industry is facing today and the tools available to support decision making.
