Measurement of Ignition Delay of Alkane Fuel Using a Shock Tube

Abstract

To investigate the effect of carbon numbers of fuel on ignition delay, Ignition delays of mixtures of n-heptane/air, n-decane/air, n-dodecane/air, and n-tridecane/air were measured using a shock tube. Results showed that the increase in carbon number of fuel shortens the ignition delay of fuel mixture at the temperatures in a range of negative temperature coefficient (NTC) region.
