Development of Micro Flowreactor, a Device for Evaluating Combustion Characteristics of Fuels in Automobiles
Group of researchers at Tohoku University in Collaboration with IHI has successfully developed “Micro Flowreactor” a fuel characterization device for evaluating combustion characteristics such as gasoline in automobiles through use of micro combustion technologies which enables the gas combustion with in a narrow tube where flames can be survived. The Micro Flowreactor is used for measuring the octane ratings an essential measurement for engine development. The newly developed consists of air-fuel mixture generating system, a small-inside-diameter glass tube, an external heater and imaging device with special optical filters. The way it works is that the temperature of air-fuel mixture within micro-diameter glass tube increases as it goes toward downstream where a temperature is maintained at high level due to an external heater.
The mixture is ignited at a position depending on fuel characteristics (an ignition temperature). Throughout this, octane ratings of specific fuels can be measured by comparing an ignition position with those of reference fuels. The new device makes the octane rating measurement easier, due to the fact that, it does not require a dedicated engines or adjustments. The first order for this new device was received from Honda R&D.
