Abstract

In order to investigate the combustion process of methanol fuel on an engine and to simulate the process in a model, experimental and simulation investigations were carried out on a compression-ignition (CI) BUKH engine using methanol with an ignition additive. First, the experimental heat release rate (HRR) of the engine was measured, followed by a simulation of the HRR using a multi-packet model and a comparison of the experimental and simulated HRR. Intermediate simulation variables (including velocities, air masses, droplet evaporation, air/fuel equivalence ratios, burning packet temperatures in different packets) were also analyzed in detail. These variables are essential for the simulation of the methanol combustion process and the subsequent modelling of emission pollutants. For methanol fuels with 5% and 7.5% ignition additive, the combustion process was analyzed as a partially premixed combustion (PPC) process. The ignition delays were 1.38 ms and 0.94 ms, respectively.
