Temperature fields during the development of autoignition in a rapid compression machine
Faraday Discussions, 2001Temperature and concentration fields have been investigated in the cylindrical combustion chamber of a rapid compression machine (RCM) by schlieren photography, chemiluminescent imaging and planar laser induced fluorescence of acetone and of formaldehyde in a 2-dimensional sheet across the diameter.

Modeling and control of controlled trajectory Rapid Compression Expansion Machine
2016 American Control Conference (ACC), 2016This paper focuses on developing the dynamic model and motion control of an electro-hydraulically actuated Rapid Compression Expansion Machine (RCEM) with a unique feature of real time trajectory control. For combustion research aimed at investigation of influence of piston trajectory on combustion kinetics, the ability to control piston trajectory is ...

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

A rapid compression machine is a type of ideal internal combustion reactor which is well suited for gas phase kinetics studies and physical processes of combustion. These studies consist in recording the evolution of the reactivity and of the composition of the reacting mixtures as a function of temperature, pressure, residence time and the composition

Effect of crevice mass transfer in a rapid compression machine
Combustion and Flame, 2014Abstract Rapid Compression Machines (RCMs) often employ creviced pistons to suppress the formation of the roll-up vortex. However, the use of a creviced piston promotes mass transfer into the crevice when heat release takes place in the main combustion chamber.

Fundamental features of hydrocarbon autoignition in a rapid compression machine
Combustion and Flame, 1993Results are reported for the autoignition characteristics of n-butane, n-pentane, n-hexane, and n-heptane and also of i-butane, i-octane, and toluene in stoichiometric mixtures with air following mechanical compression to gas temperatures in the range 600–950 K and pressures up to 0.9 MPa.

Autoignition of butane: A burner and a rapid compression machine study
Symposium (International) on Combustion, 1991The autoignition of butane has been studied by two techniques. At a relatively low pressure (1.8 bar), a two-stage flame has been fully described by following the stable-species and peroxy-radical evolution. At higher pressures, studies have been conducted in a rapid-compression machine in order to investigate the evolution of the autoignition delay ...

Autoignition of gasoline and its surrogates in a rapid compression machine
Proceedings of the Combustion Institute, 2013Abstract The analysis and interpretation of the combustion chemistry is greatly simplified by using simple mixtures of pure components, referred to as surrogates, in lieu of fully-blended transportation fuels, such as gasoline. Recognizing that the ability to model autoignition chemistry is critical to understanding the operation of Homogeneous ...
