Prism Signal Processing of Coriolis meter data for gasoline fuel injection monitoring

Influence of Fuel Injection on Gasoline Engine Performance

Because of the most common method of preparing the fuel-air mixture for gasolinefueled engines is port fuel injection (PFI). For reducing the wall-film entering the cylinder in liquid phase, the phenomena of wall-film entering the cylinder in liquid phase should be at minimum lever or be avoided. So the first thing for learning the wall-film is to detect the way of the wallfilm entering the cyl...

Random super-prism wavelength meter.

The speckle pattern arising from a thin random, disordered scatterer may be used to detect the transversal mode of an incident beam. On the other hand, speckle patterns originating from meter-long multimode fibers can be used to detect different wavelengths. Combining these approaches, we develop a method that uses a thin random scattering medium to measure the wavelength of a near-infrared las...

Studying Simultaneous Injection of Natural Gas and Gasoline Effect on Dual Fuel Engine Performance and Emissions

According to the Global Fuel Crisis, it seems necessary to use alternative fuel instead of gasoline. Since the natural gas is cheaper, have higher frequency than gasoline and less pollution, it is a suitable fuel. Many efforts have been done in order to replace gasoline with natural gas. One of the methods is to inject natural gas and gasoline fuel simultaneously and to use the benefits of both...

Correcting a Coriolis Meter for Two Phase Oil & Gas Flow

It is also common for flowmeters to be installed downstream of a two or three phase separator. If the well conditions change or the separator has been incorrectly sized, then it is possible that the oil liquid outlet may have some gas carry under. The effects of gas entrainment on the output of ultrasonic and Coriolis meters has been reported previously [1] [2]. It is already known that gas ent...
