Unburned gas temperature measurement in a spark-ignition engine using fibre-optic heterodyne interferometry

Measurement Science and Technology, 2001
A fibre-optic heterodyne interferometry system was developed to obtain the temperature histories of an unburned mixture with high temporal resolution non-intrusively. In laser interferometry, the effective optical path length of the test beam changes with the gas density and corresponding changes of the refractive index.

2-D Temperature Measurements of Unburned Gas Mixture in an Engine by Two-line Excitation LIF Technique

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">Two-line excitation LIF (Laser-Induced Fluorescence) technique for 2-dimensional temperature measurements in an engine cylinder before ignition is presented. From the fundamental examinations, the combination of toluene tracer with a pair of excitation lines of 248nm and 266nm has been selected because of the high ...

Transient Temperature Measurement of Unburned Gas in an Engine Cylinder Using Laser Interferometry with a Fiber-Optic Sensor

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">A heterodyne interferometry system with a fiber-optic sensor was developed to measure the temperature history of unburned gas in an engine cylinder. A polarization-preserving fiber and metal mirror were used as the fiber-optic sensor to deliver the test beam to and from the measurement region.

Predictions of the Knock Onset and the Effects of Heat Release Pattern and Unburned Gas Temperature on Torque at Knock Limit in S.I. Engines

SAE Technical Paper Series, 1995
<div class="htmlview paragraph">A reduced chemical kinetic model has been developed using temperature history measured by Coherent Anti-Stokes Raman Spectroscopy (CARS) and sensitivity analysis. Predictions of knock occurrence by this model show that the chemical role of residual gas and the intake flow have little effect on the knock occurrence ...
