Abstract:
The octane number is a measure of the resistance of gasoline fuels to auto-ignition. Therefore, high octane numbers reduce the engine knocking risk, leading to higher compression threshold and, consequently, higher engine efficiencies. This allows higher compression ratios to be considered during the engine design stage. Current spark-ignited (SI) engines use knock sensors to protect the engine from knocking, usually adapting the operation parameters (boost pressure, spark timing, lambda). Moreover, some engines can move the settings towards optimized parameters if knock is not detected, leadi

Abstract:
As government control has lessened, refiners are dealing with a market driven industry which will result in refineries offering gasoline of a higher octane rating. 89 octane was regarded as a target for 1992, but that level might prove non-competitive because some majors are already marketing 93 octane premium gasoline. (It is reasonable to expect that automobile manufacturers will react by offering higher perfomance engines). On a basis of a 1% annual growth rate in gasoline demand for the higher octane fuels, US refiners surplus gasoline supply capability will be exhausted in 1990. This proj

There may occur a special mode of combustion of the fuel-air mixture called detonation, when using motor fuel with a low octane rating.

A nonlinear multidimensional QSPR regression model is proposed to predict the octane number of normal and substituted alkanes-gasoline components.

This paper reviews the fundamental requirements of liquid hydrocarbon fuels for spark ignition engines, namely that the fuel should vaporise satisfactorily and burn in a controlled manner. The phenomenon of knock and the development of the octane scale are discussed. The variation in the pressure–time histories for different engines is discussed, together with the reason why this leads to different fuel requirements. The difference in the octane rating tests and the way in which engine downsizing exacerbates these differences in the pressure–time histories are discussed. The applicability of t

There are numerous numerical and experimental studies to find correlations of octane rating with fuel properties. This thesis was based on the hypothesis that quenching characteristics at ignition locations impact the flame development. Conversely, determination of quenching characteristics might serve as an effective measure to determine the fuel mixture octane number. This hypothesis was tested with premixed flame experiments using primary reference fuels (iso-octane and n-heptane) and commercial grade gasoline. Premixed flame experiments were conducted on a flat flame burner. Primary refere

Abstract:
Due to the lead phase out that began in 1973, refiners had to replace the octane loss in gasoline. For this purpose, oxygenates and highly branched alkylates will play a major role as gasoline additives because they have relatively high octane ratings. Methyl tertiary-butyl ether (MTBE) is the oxygenate as a gasoline additive the most widely used nowadays in most of the countries in the world. It is used to raise octane levels, enhance engine performance, improve combustion efficiency and to reduce emissions of air pollutants such as carbon monoxide and hydrocarbons.

Abstract:
‘Steps towards the periodic table’ outlines the different versions of the periodic table that were devised in the 1860s following the Karlsruhe conference in Germany, which introduced standardized atomic weights. De Chancourtois actually discovered periodicity, but his ideas did not gain traction for many years. Newlands devised the law of octaves, but the musical analogy garnered ridicule from academics. Odling made important discoveries in periodicity, but lacked enthusiasm for the idea. Hinrichs used his wide range of interests to postulate that the ratios of atomic size could explain each element’s unique spectral fingerprint. Meyer made huge strides in discovering periodicity, but, due to a misplaced table, did not get the recognition he deserved.

Instructional plans consist of planning necessities, standard alignment, alignment to philosophies approached in earlier chapters, as well as instructional procedures and assessments. Adaptations for other grade-level bands as well as potential extensions are available for each plan. This chapter includes the following instructional plans: Audio Engineering: Ratios in Recording, Designing a Chromatic PVC Instrument, Controlled Voltage: Composing, Performing, and Improvising with Subtractive Electronic Synthesis, and Sound Pollution and Its Effects on Local Bird Ecology. In Audio Engineering: Ratios in Recording, students will use a method of measuring and experimentation to maximize the sound quality of a given recording environment. In Designing a Chromatic PVC Instrument, students will design a one octave chromatic instrument using mathematical calculations and representations to create initial expressive statements and explain the relationships among the frequency, wavelength, and speed of waves traveling in the PVC pipes. In Controlled Voltage: Composing, Performing, and Improvising with Subtractive Electronic Synthesis, students will interface with the subtractive architecture of electronic instruments, the concept of controlled voltage, and the function of an electronic sequencer. In Sound Pollution and Its Effects on Local Bird Ecology, students will learn about modern sound pollution and the effect it has on many different forms of ecology. Students will determine at the end of their own study whether or not there were any observed correlations between these datas captured, and if other data could be used to claim causation.

Abstract:
The Fourier transform is not particularly conducive in the illustration of the evolution of frequency with respect to time. A representation of the temporal evolution of the spectral content of a signal is referred to as a time-frequency representation (TFR). The TFR, in essence, attempts to measure the instantaneous spectrum of a dynamic signal at each point in time. Musical scores, in their most fundamental interpretation, are TFR’s. The fundamental frequency of the note is represented by the vertical location of the note on the staff. Time progresses as we read notes from left to right. The musical score shown in Figure 9.1 is an example. Temporal assignment is given by the note types. The 120 next to the quarter note indicates the piece should be played at 120 beats per minute. Thus, the duration of a quarter note is one half second. The frequency of the A above middle C is, by international standards, 440 Hertz. Adjacent notes notes have a ratio of 21/12. The note, A#, for example, has a frequency of 440 × 21/12 = 466.1637615 Hertz. Middle C, nine half tones (a.k.a. semitones or chromatic steps) below A, has a frequency of 440 × 2−9/12 = 261.6255653 Hertz. The interval of an octave doubles the frequency. The frequency of an octave above A is twelve half tones, or, 440 × 212/12 = 880 Hertz. The frequency spacings in the time-frequency representation of musical scores such as Figure 9.1 are thus logarithmic. This is made more clear in the alternate representation of the musical score in Figure 9.2 where time is on the horizontal axis and frequency on the vertical. At every point in time where there is no rest, a frequency is assigned. To make chords, numerous frequencies can be assigned to a point in time. Further discussion of the technical theory of western harmony is in Section 13.1.

Knock is a major impediment to achieving higher efficiency in Spark-Ignition (SI) engines. The recent trends of boosting, downsizing and downspeeding have exacerbated this issue by driving engines toward higher power density and higher load duty cycles. Apart from the engine operating conditions, fuel anti-knock quality is a major determinant of the knocking tendency in engines, as quantified by its octane number (ON). The ON of a fuel is based on an octane scale which is defined according to the standard octane rating methods for Research Octane Number (RON) and Motor Octane Number (MON). The
