Available in PDF, EPUB and Kindle. Book excerpt: A major obstacle to improving spark ignition engine efficiency is the limitations on compression ratio imposed by tendency of hydrocarbon fuels to knock (autoignite). A research program investigated the knock problem in spark ignition engines. Objective was to understand low and intermediate temperature chemistry of combustion processes relevant to autoignition and knock and to determine fuel property effects. Experiments were conducted in an optically and physically accessible research engine, static reactor, and an atmospheric pressure flow reactor (APFR). Chemical kinetic models were developed for prediction of species evolution and autoignition behavior. The work provided insight into low and intermediate temperature chemistry prior to autoignition of n-butane, iso-butane, n-pentane, 1-pentene, n-heptane, iso-octane and some binary blends. Study of effects of ethers (MTBE, ETBE, TAME and DIPE) and alcohols (methanol and ethanol) on the oxidation and autoignition of primary reference fuel (PRF) blends.

Book excerpt: Our engine studies have concentrated on 2 areas of interest to autoignition and emissions from engines. In the first, we investigated the effect of nitric oxide (NO) on the reactivity and autoignition behavior of 87 PRF. In the second study, we continued work on the effects of blending ethers on the reactivity and autoignition of a primary reference fuel blend, 87 PRF, with emphasis placed on the chemical interactions between ethers and the baseline fuel. The effects of nitric oxide (NO) on the reactivity and autoignition behavior of 87 PRF were examined in our research engine under motored conditions at compression ratios of 5.2 and 8.2. The most significant conclusions of our study are: (1) nitric oxide does interact with the hydrocarbon oxidation at conditions typically experienced by the end gas in a fired engine; (2) the effect is complex and, depending on the reaction environment, the same concentration of NO can produce dramatically different results. These results are particularly important given the fact that residual fractions and recycled exhaust gases in spark ignited engines typically result in about 200--600 ppm of NO in the unburned charge. The octane enhancing ethers, MTBE, ETBE, TAME, and DIPE, were blended into 87 PRF at a constant 0 atom fraction of 1.94% in the fuel mixtures and the mixtures were tested under motored conditions at our new compression ratio of 8.2. This new compression ratio allows studies on autoignition behaviors of 87 PRF with and without ethers. The results showed that, when using 87 PRF/ether mixtures, reactivity was significantly reduced as indicated by the higher inlet temperature required to initiate reactivity, significantly lower maximum CO concentration and the significantly higher inlet temperature required for autoignition.

Available in PDF, EPUB and Kindle. Book excerpt: Non-uniform combustion, as encountered in diesel and gas turbine engines, furnaces, and boilers, is responsible for the conversion of fossil fuel to energy and also for the corresponding formation of pollutants. In spite of great research efforts in the past, the mechanism of non-uniform combustion has remained less explored than that of other combustion types, since it consists of many, mostly transient processes which influence each other. In view of this background, a group research project, "Exploration of Combustion Mechanism", was established to explore the mechanism of combustion, especially that of diffusive combustion, and also to find efficient ways to control the combustion process for better utilization of fuel and the reduction of pollutant emission. The group research was started, after preparatory activity of 2 years, in April 1988, for a period of 3 years, as a project with a Grant-in-Aid for Scientific Research of Priority Area subsidized by the Ministry of Education, Science and Culture of Japan. The entire group of 43 members was set up as an organizing committee of 13 members, and five research groups, consisting of 36 members. The research groups were: (1) Steady combustion, (2) Unsteady spray combustion, (3) Control of combustion, (4) Chemistry of combustion, and (5) Effects of fuels. At the beginning of the project it was agreed that we should pursue the mechanism of combustion from a scientific viewpoint, namely, the target of the project was to obtain the fundamentals, or "know why", rather than "know how" of combustion.
