“…, is the corresponding resonance mode factor, m and n are the numbers of radial and circumferential pressure nodes, respectively; B is the bore of the cylinder, and c is the velocity of local sound in the combustion chamber, which depends on temperature and pressure. [38,39]. When the characteristic frequencies of the first radial mode (1, 0) and the second radial mode (2, 0) are calculated, the resonant frequencies of the different modes are 6.96 kHz and 11.55 kHz, which is consistent with the experimental results.…”

“…Moreover, as was observed for diesel engines [27,28], this category of alternative fuels feature lower particle emissions owed to specific differences in molecular structure [29]. Both affirmations have been somewhat extensively investigated at part load [30,31] while at high engine load there is relatively reduced literature available [32,33].…”

Within the context of ever wider expansion of direct injection in spark ignition engines, this investigation was aimed at improved understanding of the correlation between fuel injection strategy and emission of nanoparticles. Measurements performed on a wall guided engine allowed identifying the mechanisms involved in the formation of carbonaceous structures during combustion and their evolution in the exhaust line. In-cylinder pressure was recorded in combination with cycle-resolved flame imaging, gaseous emissions and particle size distribution. This complete characterization was performed at three injection phasing settings, with butanol and commercial gasoline. Optical accessibility from below the combustion chamber allowed visualization of diffusive flames induced by fuel deposits; these localized phenomena were correlated to observed changes in engine performance and pollutant species. With gasoline fueling, minor modifications were observed with respect to combustion parameters, when varying the start of injection. The alcohol, on the other hand, featured marked sensitivity to the fuel delivery strategy. Even though the start of injection was varied in a relatively narrow crank angle range during the intake stroke, significant differences were recorded, especially in the values of particle emissions. This was correlated to the fuel jet-wall interactions; the analysis of diffusive flames, their location and size confirmed the importance of liquid film formation in direct injection engines, especially at medium and high load.

“…Unlike ethanol, butanol is far less corrosive allowing it to be delivered using the existing facilities to ship conventional fuel [72,82]. Being less corrosive means that butanol can also be used without any modification to the vehicle [83,84]. If it is contaminated with water, it is hard to separate from the base fuel (gasoline/diesel).…”

Several studies on ethanol as a biofuel have been comprehensively carried out. Today, a growing interest in longer chain alcohols has emerged due to their favourable physical and thermodynamic properties. Butanol or butyl alcohol with 4-carbon structure (C4H9OH) is a more promising biofuel as it outweighs methanol and ethanol in several ways. The production cost of butanol has been gradually reduced, and rapid progress in the development of its production technology has allowed butanol to be produced more effectively. However, studies on the effect of butanol on gasoline or spark ignition (SI) engines are not as comprehensive as the abundant research of ethanol. This paper highlights recent novelty and contribution of butanol addition in SI engine. Results of new approaches on the engine’s performance, combustion and emission characteristics are summarised. Reviews from this paper suggest that there are some gaps in the addition of butanol found in the literature. Thus, several encounters and forthcoming research directions are outlined in the final section of this review article, highlighting several possible contributions that have not yet been carried out using butanol as a biofuel in a gasoline engine.
