Abstract: A rapid compression machine (RCM) employs an electrical drive to move a piston disposed within a chamber housing. The electrical drive converts electrical power into linear motion of the piston, for example, to compress contents in a reaction chamber defined by the chamber housing and the piston. The temperature and pressure changes induced by the compression can cause reaction of contents within the chamber, for example, autoignition of the contents. The RCM can thus be used to study chemical kinetics. In some embodiments, the electrical drive can also rapidly move the piston in reverse to expand a volume of the reaction chamber, for example, to quench the compression-induced reaction therein. In such embodiments, the RCM may be considered a rapid compression-expansion machine (RCEM) and can be used for speciation studies.
