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 ...

Knocking Phenomena in a Rapid Compression and Expansion Machine
SAE Technical Paper Series, 1992<div class="htmlview paragraph">In this study, a rapid compression and expansion machine(RCEM) with a pancake combustion chamber was designed to investigate fundamentally on the knocking phenomena in spark ignition(S.I) engines. This RCEM is intended to simulate combustion in an actual engine.

Studies of fuel injection into a rapid compression machine
Combustion and Flame, 1981Abstract An opposed-piston rapid compression machine has been fitted with a single-shot diesel injection system. The ignition of fuel sprays has been studied over a range of experimental conditions, using decane or blends of decane with lower cetane quality aliphatic and aromatic basestocks.

Experiments in Stratified Combustion with a Rapid Compression Machine
SAE Technical Paper Series, 1978<div class="htmlview paragraph">The foundation for engine performance and emissions models is a phenomenological description of the combustion process. In this work, high speed movies and analysis of rapid compression machine experiments have been used to develop an understanding of the mechanisms that control combustion rates in the Texaco ...

Soot Formation Study in a Rapid Compression Machine
Journal of Engineering for Gas Turbines and Power, 2005A rapid compression machine was used to study the soot formation process under diesel enginelike conditions. The apparatus creates accurately controlled conditions at the end of compression (uniform mixture, temperature, and well-defined mixture composition) and, by decoupling chemistry with mixing, provides an unambiguous data interpretation for ...

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 ...

Autoignition of Alcohols and Ethers in a Rapid Compression Machine
SAE Technical Paper Series, 1993<div class="htmlview paragraph">The autoignition characteristics of methanol, ethanol and MTBE (methyl tert-butyl ether) have been investigated in a rapid compression machine at pressures in the range 20-40 atm and temperatures within 750-1000 K.

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.

Study of Homogeneous Charge Compression Ignition Using a Rapid Compression Machine
SAE Technical Paper Series, 2001<div class="htmlview paragraph">The purpose of this study is to explain the characteristics of homogeneous charge compression ignition. n-Heptane, which has the same cetane number as diesel fuel, was chosen for the fuel. A rapid compression machine was used to clarify the effects of air-fuel ratio, O<sub>2</sub> concentration, and ...
