Download or read book Partial Oxidation for Improved Cold Starts in Alcohol fueled Engines written by and published by . This book was released on 1998 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alcohol fuels exhibit poor cold-start performance because of their low volatility. Neat alcohol engines become difficult, if not impossible, to start at temperatures close to or below freezing. Improvements in the cold-start performance (both time to start and emissions) are essential to capture the full benefits of alcohols as an alternative transportation fuel. The objective of this project was to develop a neat alcohol partial oxidation (POX) reforming technology to improve an alcohol engine's ability to start at low temperatures (as low as -30 C) and to reduce its cold-start emissions. The project emphasis was on fuel-grade ethanol (E95) but the technology can be easily extended to other alcohol fuels. Ultimately a compact, on-vehicle, ethanol POX reactor was developed as a fuel system component to produce a hydrogen-rich, fuel-gas mixture for cold starts. The POX reactor is an easily controllable combustion device that allows flexibility during engine startup even in the most extreme conditions. It is a small device that is mounted directly onto the engine intake manifold. The gaseous fuel products (or reformate) from the POX reactor exit the chamber and enter the intake manifold, either replacing or supplementing the standard ethanol fuel consumed during an engine start. The combustion of the reformate during startup can reduce engine start time and tail-pipe emissions.

Available in PDF, EPUB and Kindle. Book excerpt: This project was designed to experimentally validate a prototype integrated cold-start system for alcohol-fueled engines. During the project, the subcontractor designed a simple and compact prototype partial oxidation (POX) reactor and demonstrated its operational performance on liquid E95 at low temperatures. "Turn-key" operation of the system was successfully demonstrated, along with rapid engine starts and transition to sustained idle at very low temperatures. Based on project results, it appears that continued development of an integrated POX system as a component of the fuel system may offer the best opportunity for improving cold startability and thus acceptability of alcohol fuels.

Available in PDF, EPUB and Kindle. Book excerpt: Neat alcohol fuels offer several benefits over conventional gasoline in automotive applications. However, their low vapor pressure and high heat of vaporization make it difficult to produce a flammable vapor composition from a neat alcohol fuel during a start under col ambient conditions. Various methods have been introduced to compensate for this deficiency. In this study, we applied computer modeling and simulation to evaluate the potential of four cold-start technologies for engines fueled by near-neat alcohol. The four technologies were a rich combustor device, a partial oxidation reactor, a catalytic reformer, and an enhanced ignition system. We ranked the competing technologies by their ability to meet two primary criteria for cold starting an engine at -25 deg. C and also by several secondary parameters related to commercialization. Our analysis results suggest that of the four technologies evaluated, the enhanced ignition system is the best option for further development.

Download or read book Reducing Cold Start Hydrocarbon Emissions from Port Fuel Injected Spark Ignition Engines with Improved Management of Hardware Controls written by Kevin R. Lang and published by . This book was released on 2006 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) By timing split injection such that the second injection event hits the overlap back flow, a small mixture preparation and emissions benefit was achieved. Earlier IVO results in a longer back flow period, however the impact on mixture preparation is small. The observed reduction in HC emissions resulted from a higher residual gas fraction due to early IVO, which yielded later combustion phasing, which in turn yielded increased post-flame oxidation. Under steady-state cold coolant conditions, operation of a 4-cylinder engine with three cylinders running rich and the fourth used to pump air into the exhaust manifold resulted in near total oxidation of CO and HC at sufficiently retarded spark timing. Exhaust gas temperatures and enthalpy flow rates were significantly higher than for the conventional engine configuration at fast idle. Using this strategy to perform real cold starts proved challenging without the additional hardware needed for sufficient control over air flow to the engine.
