Study of effects of ignition improvers on ethanol compression ignition in the rapid compression machine

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2020
The world recognizes that the main source of energy used in transportation is diesel fuel because it is more economical and is also more efficient. For this reason, various sectors of transport and fuel production are developing new technologies aiming at the replacement of traditional fossil fuels by other renewable sources.

CFD studies of a twin-piston rapid compression machine

Combustion and Flame, 2005
Abstract 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 ...

Experimental and modeling study of the autoignition for diesel and n-alcohol blends from ethanol to n-pentanol in shock tube and rapid compression machine

Combustion and Flame, 2021
The ignition delay times (IDTs) of n-alcohol/diesel blends were measured in a heated shock tube (ST) and a heated rapid compression machine (RCM). Three sets of blends were formulated to investigate the effect of n-alcohol (the volume ratio of n-alcohol ...

A rapid compression machine coupled with time-resolved molecular beam mass spectrometry for gas-phase kinetics studies.

Review of Scientific Instruments, 2021
Rapid compression machines (RCMs) are used to simulate a single stroke of an internal combustion engine. After a high-speed compression process, a high-pressure and low-to-intermediate temperature condition can be obtained, under which ignition processes
