Math at Top Speed: Exploring and Breaking Myths in the Drag Racing Folklore

March 11, 2010  7:00 PM        rOOM: CPE 2.206 (the Chem and Petr Eng building)

Speaker: Professor Richard Tapia, Dept of Computational and Applied Mathematics, Rice University

 In this talk, Prof. Tapia will identify elementary  mathematical frameworks for the study of  popular drag racing beliefs. In this manner some myths are validated, while others are destroyed.  Prof. Tapia will explain why dragster acceleration is greater than the acceleration due to gravity, an age old inconsistency. His "Fundamental Theorem of Drag Racing" will be presented.  The first part of the talk will be a historical account of the development of drag racing and will include several lively videos.(PowerPoint)

 

Officer Elections and A study of dedicated EGR cylinders to improve the fuel economy of a gasoline engine

Sept. 16, 2009        rOOM: ETC 2.136        7:00pm

Speaker: Darius Mehta (MSME UT) Southwest Research Institute (the largest independent automotive R&D facility in the US)

Southwest Research Institute® (SwRI) has demonstrated in the HEDGE® program that a spark ignited (SI) gasoline engine can be operated with high levels of exhaust gas recirculation (EGR) to achieve fuel economy approaching that of a Diesel engine. A key technology associated with this success is the air handling system, which must provide as much as 50% EGR in a manner that does not adversely affect engine pumping, turbocharger performance, or transient response. SwRI has proposed a new EGR system that separates the exhaust runner of one (or more) cylinder from the main exhaust manifold and reroutes it directly into the intake manifold. With this configuration, all of the burned gases from the separated exhaust runner are considered EGR, and hence the cylinder is called a dedicated EGR (D-EGR) cylinder. In the case of a four cylinder engine with one D-EGR cylinder, the engine is essentially operated at a fixed EGR rate of 25%. This fixed EGR rate greatly simplifies transient control of EGR, as the fixed EGR rate is maintained as air flow rates are increased or decreased during the transient. More importantly, the air-fuel ratio of the D-EGR cylinder is controlled separately of the other cylinders, and can be made to operate fuel-rich such that a small amount of hydrogen is generated. This small quantity of hydrogen significantly improves the EGR tolerance and burn rate of the engine, both of which contribute to fuel economy improvement. The D-EGR cylinder can also be made to operate fuel-lean if high oxygen content EGR is needed.
 
In this work, one-dimensional cycle simulation was used to identify the appropriate layout of the air handling system, including supercharger and/or turbocharger size and arrangement needed to achieve 50% EGR.  Engine investigations were then conducted on a 3.5L V6 gasoline engine to assess whether it was possible to operate an engine with 50% EGR, and to determine what fuel economy improvement was available.

 

Translating what the customer cares about into engineering metrics

APR 29, 2009        rOOM: ETC 2.136        7:00pm

Rob Smithson, Vice President - Product Development, Fallbrook Technologies, Cedar Park, TX, and an SAE Fellow

Abstract: It’s very easy to get caught up in engineering measurables like efficiency and performance, but not understanding how the customer for your product or service values these things, if they even value them at all, can lead to the wrong engineering decisions and, more importantly, an unsuccessful product in the marketplace. We’ll talk about how simple performance metrics like efficiency aren’t sufficient to make product design decisions, and discuss some examples of non-linear performance thinking in real world products that were big hits in the marketplace.

Catalysts and Emissions

February 5, 2003

Dr. Todd H. Ballinger and Johnson Matthey will give a lecture at 7PM in ETC 2.136 on Vehicle Comparisons of Advanced Three-Way Catalysts and Hydrocarbon Trap Catalysts for Low Emission Vehicles. In order to meet the most stringent government regulations for pollutant emissions from automobiles, cold-start hydrocarbon emissions must be controlled.  Hydrocarbon trap catalysts are one method of reducing cold-start hydrocarbon emissions, but this study demonstrates that the efficiency of the trap catalyst is dependent on the hydrocarbon speciation of the cold-start engine exhaust
