“…It was reported that gasoline has high octane number-100 [57] and it can be used as low reactive fuel. However, it can also be utilised as high reactive fuel with the use of cetane enhancer (Di Tertiary Butyl Peroxide or Ethyl Hexyl Nitrate) [58][59][60]. The experiment results were reported with the use of normal gasoline (port injection) and gasoline doped with 0.75%, 1.75% and 3.5% Di Tertiary Butyl Peroxide (DTBP) by volume (direct injection).…”

Compression ignition (CI) engines are used in heavy duty engine applications due to their high torque capability and thermal efficiency. However, high NOx and smoke emissions are the challenges in using CI engines. Homogeneous charge compression ignition (HCCI) is one of the best methods to reduce NOx and smoke emissions. However, controlling the combustion for an entire range of operation in HCCI mode is a challenging task. Different methods like fast thermal management (FTM), exhaust gas recirculation (EGR), turbo charging and reactivity controlled compression ignition (RCCI) are reviewed and discussed in this article. RCCI is similar to HCCI, which uses reactivities of two different fuels to control combustion. The combustion objectives of HCCI such as less NOx and soot emission can also be obtained through this method. Combustion control based on reactivities of various fuels (RCCI) is discussed significantly. Fuels that have different reactivities can help to control the combustion phasing and thereby reducing the emission. Two different fuels can be injected together into the manifold or one fuel can be injected in the port and other in the combustion chamber directly for reactivity based combustion control. The technological development in different combustion control methods is reviewed and discussed in this article which is a useful knowledge base for further research investigations. When compared to other combustion control methods, RCCI is found to be advantageous in all perspectives such as cost, flexibility in control, simplicity and wide range of operation.

“…While strategies to use typical gasoline and diesel fuels in HCCI engines have been investigated [7,9], another option is to find new fuels or fuel blends that may offer more attractive performance. Various groups studied the operating ranges of different fuels in HCCI engines with the goal of identifying attractive species or mixtures [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The fuels studied include-but are not limited to-real fuels such as gasoline [10,11,17,[20][21][22], diesel [10,18,20], and Jet B [18].…”

In addition, numerous studies focused on neat fuels and mixtures of such, including n-butane [11], neat and blends of the primary reference fuels (PRFs) n-heptane and isooctane [10-13, 16, 17, 19, 22, 23], and mixtures of the PRFs with toluene [22,23] and ethanol [17,22,23] both individually and together [23].…”

A new metric for ranking the suitability of fuels in LTC engines was recently introduced, based on the fraction of potential fuel savings achieved in the FTP-75 light-duty vehicle driving cycle. In the current study, this LTC fuel performance index was calculated computationally and analyzed for a number of fuel blends comprised of n-heptane, isooctane, toluene, and ethanol in various combinations and ratios corresponding to octane numbers from 0 to 100. In order to calculate the LTC index for each fuel, computational driving cycle simulations were first performed using a typical light-duty passenger vehicle, providing pairs of engine speed and load points. Separately, for each fuel blend considered, single-zone naturally aspirated HCCI engine simulations with a compression ratio of 9.5 were performed in order to determine the operating envelopes. These results were combined to determine the varying improvement in fuel economy offered by fuels, forming the basis for the LTC fuel index. The resulting fuel performance indices ranged from 36.4 for neat n-heptane (PRF0) to 9.20 for a three-component blend of n-heptane, isooctane, and ethanol (ERF1). For the chosen engine and chosen conditions, in general lower-octane fuels performed better, resulting in higher LTC fuel index values; however, the fuel performance index correlated poorly with octane rating for less-reactive, higher-octane fuels.
