Studying the chemistry of HCCI in rapid compression machines
International Journal of Vehicle Design, 2007The rapid compression machine is an ideal tool to investigate the chemistry of the HCCI engine as important factors controlling both devices are the same. There is no tool that describes, meaningfully, the physical and chemical processes occurring in one of the simplest research tools, the rapid compression machine and typically, processes are ...

CFD studies of a twin-piston rapid compression machine
Combustion and Flame, 2005Abstract A transient 2-dimensional moving mesh CFD computer model was created, validated against experimental data, and used to investigate the flow and resulting temperature fields in a rapid compression machine. The sensitivity of the horizontally opposed twin-piston RCM to nonsynchronized and non-uniform piston strokes was determined and the ...

Autoignition Study of 1-Methylnaphthalene in a Rapid Compression Machine
Energy & Fuels, 20161-Methylnaphthalene (1-MN), also known as α-methylnaphthalene, is a substituted diaromatic hydrocarbon that is widely used as one of the representative aromatic hydrocarbons in surrogate fuels of diesel. The ignition characteristics of 1-MN have been investigated in the present study using a rapid compression machine (RCM) at compressed pressures of PC

An Opposed Piston Rapid Compression Machine for Preflame Reaction Studies
Proceedings of the Institution of Mechanical Engineers, 1968Mixtures of fuel and air ignite spontaneously if exposed to sufficiently high temperatures. Such ignition is not an instantaneous event, and there is always a delay of chemical origin between the establishment of the particular conditions of temperature and pressure and the rapid, exothermic chemical reactions that constitute ignition.

Ethanol-Powered Combustion Experimental Study in a Rapid Compression Machine
SAE Technical Paper Series, 2013<div class="section abstract"><div class="htmlview paragraph">Nowadays, many researches are being carried out to replace the diesel by alternative fuels. Biodiesel and ethanol are strong candidates for this purpose. However, the experimental study of the combustion of biofuels in engines is not an easy task.

Ignition of an iron bed in a rapid compression machine
Combustion, Explosion, and Shock Waves, 2011A pointwise semi-empirical mathematical model is proposed, which ensures an adequate description of experimental data on the delay of ignition of a bed of iron particles in a rapid compression machine as a function of the ambient temperature.
