Biofire – Biogenic Fuel Ignition Research

The increasing use of biofuels is a major challenge for combustion engine manufacturers in terms of performance and CO2 efficiency. The cetane number, as it is one of the most important fuel numbers for Diesel fuels, is derived from the ignition delay which represents the period between the beginning of fuel injection and the start of combustion. This ignition delay is evaluated by using a single cylinder test engine and measuring the time difference between the signal of the needle stroke sensor which is mounted directly at the injection valve and the maximum pressure increase in cylinder.
