The ignition delay time is a crucial parameter in the glow plug ignition of micro-internal combustion engine (MICE). The effects of important operating parameters, such as the fuel species (methane, ethane, propane and n-butane), the initial temperature (500 K ~ 1 000 K), the initial pressure (1 ~ 10 atm) and equivalence ratio (0.6 ~ 1.2), on the ignition delay times were carried out via numerical simulation with Chemkin-Pro software. In addition, the effects of the residual exhaust gas caused by halfway scavenging on the ignition delay times of n-butane/air mixtures were investigated. The result shows that n-butane is a suitable fuel for MICE with glow plug ignition because of its short ignition delay time. Meanwhile, the ignition delay time decreases with the increase of the initial temperature, pressure and equivalence ratio. Moreover, the residual exhaust gas causes an increase of the ignition delay time of n-butane/air mixtures, and components of the exhaust have separated influence on the ignition delay time due to their different thermal and the chemical kinetic effects.
