“…A traditional estimator [47] of the cycle-bycycle variation is the Coefficient of Variation of Indicated Mean Pressure ðCOV IMEP ¼ ðs IMEP =m IMEP Þ$100Þ, obtained by nondimensionalising the standard deviation with the mean value of IMEP. With the diagnostic model, the MFB of each cycle as a function of crank angle for six series (shown in Fig.…”

Spark ignition engine Combustion diagnosisAlternative fuels Genetic algorithm a b s t r a c tA methodology is presented for studying the influence of using alternative fuels on the cycle-to-cycle variations of a spark ignition engine which has been fuelled with mixtures of natural gas and hydrogen in different proportions (0e100%). The experimental facility consists of a single-cylindrical spark ignition engine coupled to an asynchronous machine IntroductionBecause of the increasing concern about energy deficiency and environmental defence, much effort has been focused on the use of alternative fuels in internal combustion engines (ICE). Alternative fuels are clean, when compared to conventional ones derived from petroleum in ICE. Natural gas (NG) is considered to be a probable alternative fuel due to its properties and higher octane number. NG is a mixture of different gases where methane is its main constituent (75e98% of methane; 0.5e13% of ethane; and 0e2.6% of propane [1] Available online at www.sciencedirect.com journal h om epa ge: www.elsev ier.com/locate/he i n t e r n a t i o n a l j o u r n a l o f h y d r o g e n e n e r g y 3 8 ( 2 0 1 3 ) 1 5 4 7 7 e1 5 4 8 7

“…An initial estimation of the importance of cycle-to-cycle variation is made with the coefficient of variation (COV) of the indicated mean pressure [18,19], calculated as the ratio of the standard deviation and the mean value (Eq. (5)).…”

“…Recently it also has been studied in homogeneous charge compression ignition (HCCI) engine processes [14], compression ignition engines [15] and also by using CFD simulations [16]. A traditional [17][18][19][20][21][22] estimator of the cycle-to-cycle variation is the Coefficient of Variation in Indicated Mean Pressure, COV IMEP . In this paper, the authors propose complementary considering the variation of the mass fraction burning rate of each individual cycle to characterize cyclic variation, as explained later (Fig.…”
