摘要： A gas fuel injector (3) supplies gas fuel from a gas cylinder (1) into a measuring section thin tube (5), and a pressure measuring device (4) measures pressure variation in the tube through a small hole provided in the thin tube (5). On the downstream side of the measuring section thin tube (5), an extension thin tube (6) for removing the influence of reflected wave is provided. At the downstream side end of the extension thin tube, a back pressure valve (13) for increasing the pressure in the tube uniformly and bringing it close to the actual environment in the engine cylinder is provided. Furthermore, a tapered nozzle is arranged in the measuring section thin tube (5). Pressure measured by the pressure measuring device (4) is converted into the flow rate in the thin tube according to a predetermined calculation expression. Consequently, instantaneous flow rate of gas fuel being ejected from the gas fuel injector (3) can be measured.

摘要： A method for determining the total mass flow through an engine (10) comprises measuring (32) the fuel flow to the engine (10) and measuring the concentration of carbon dioxide in the gases exhausted (22) from the engine (10). The concentration of carbon dioxide is measured by detecting the infrared radiation absorption spectrum of carbon dioxide using a laser (38) and a detector (46). The method comprises determining (48) the air to fuel ratio in the engine (10) from the fuel flow and the concentration of carbon dioxide. The method comprises determining (48) the air mass flow through the engine (10) from the air to fuel ratio and calculating (48) the total air and fuel mass flow through the engine (10) by adding the air mass flow through the engine (10) to the fuel mass flow to the engine (10).

摘要： A remaining fuel Z is calculated by subtracting a fuel injection amount J supplied to an engine 14 from stored fuel F measured by a fuel meter 12. A fuel economy Fm is calculated by dividing a running distance M of a vehicle by a fuel injection amount J. A cruising distance K is calculated by multiplying the remaining fuel Z and the fuel economy Fm.

Die Messblendenöffnung erstreckt sich in vertikaler Richtung in dem Behälter nach oben, beginnend auf einem Überlaufniveau mit einem vorgegebenen Abstand oberhalb des Behälterbodens. Die Messvorrichtung weist ferner einen Drucksensor auf, der im oder am Behälter wenigstens teilweise unterhalb der Messblendenöffnung angeordnet ist, um den statischen Druck in einer sich im Behälter durch Zulauf der Flüssigkeit ansammelnden Flüssigkeitssäule zu messen.
Die erfindungsgemäße Messvorrichtung ist dadurch gekennzeichnet, dass ein unterer Bereich der Messblendenöffnung verschließbar ist, um das Überlaufniveau zur Überprüfung der Kalibrierung der Messvorrichtung um ein vorgegebenes Ausmaß zu erhöhen.

摘要： A method for measuring the quantity of fluid ejected by an injector is described, characterised in that it provides the following steps:
a) the pressure trend inside a chamber is detected during a certain number of stabilised injection cycles;
b) the average liquid flow rate is measured;
c) from the average liquid flow rate and from the difference between the instant pressures and the outlet pressure, parameters C 0 , C 1 and C 2 are obtained, which allow to calculate the instant flow rate of the injector;
d) by employing the three parameters, the value of the instant flow rate is obtained on the basis of the pressure derivative with respect to time.
Furthermore, a device is described to put the above-said method into practice.

摘要： Method and arrangement for accommodating indirect ascertainment of fill-characteristics of fluid tanks on marine vessels. The invention includes providing an experientially-based mapping of volume characteristics of a fluid tank positioned on a marine vessel that are correlated with respect to measurable fluid surface positions within the fluid tank. In consideration of this volume characteristic mapping, fluid fill condition information is output for operator use based on quantification of a parameter other than sensed fluid level in the fluid tank. While it is contemplated that the other parameter may be any characteristic that readily reads back to the volume characteristic mapping, it is particularly advantageous, and a preferred embodiment of the invention, that the other parameter be a volumetric quantification of fluid consumed out of the tank can be compared to an earlier ascertained tank volume.

摘要： An engine performance map which specifies the relation between running conditions and brake specific fuel consumption (BSFC) is generated by estimating the BSFC relative to the engine rotation speed and accelerator depression amount, based on the BSFC characteristics predicted from the torque pattern of the vehicle being analyzed and the optimum BSFC. A vehicle mounted unit 1 computes the BSFC of the engine by looking up the engine performance map based on the engine rotation speed and accelerator depression amount, and computes the fuel consumption rate based on this BSFC.
