Abstract

The analysis of gasoline-ethanol blend sprays in engine-like conditions is of
fundamental importance for the study and development of engines. The development of
spray characteristics concepts requires an efficient investigation and improvement of the
applied systems. For a correct understanding of the processes inside the combustion
chamber of an internal combustion engine, especially for smaller sizes of engines, a
system is necessary which allows a fast adaptation to the desired parameters and
efficient conduction of the experiments. For this purpose, a High-Pressure Chamber
(HPC) in a 1:1 scale for small-bore engines (piston displacement approximately 76 mm)
with variable optical access (6 windows) has been developed. A high-pressure chamber
(HPC) has been designed for the purpose of spray characteristics studies at elevated
pressures. The present HPC is designed as a versatile tool and includes the features of a
well-defined core region, fast pressurize, ability to vary pressure and clearance, optical
accessibility, and capability for piece measurement.
