Abstract

It is generally known that fuel volatility considerably influences driveability and the composition of exhaust gas. Recently, many papers have clarified the relationship between the influence of driveability / exhaust gas composition with fuel volatility expressed by such parameters as T 10, T 50, RVP. These papers suggest that detection of fuel volatility can be very useful in engine control systems. This prompted us to study fuel volatility sensors, paying attention to the correlation between cavitation number and vapor pressure. This paper describes the development of a Fuel Composition Sensor with a long orifice to facilitate cavitation and a photocoupler to detect cavitation events.
