Experiment apparatus for measuring spray particle size and speed in combustion chamber

摘要

The present invention relates to an experimental apparatus for measuring the spray particle size and speed in the combustion chamber, it is difficult to accurately measure the fuel injection timing, the size of the fuel spray particles, the spray rate of the fuel, etc., which have a large effect on the output of the engine. In addition, the simulation experiments by simulating various operating conditions have a problem that it is difficult to determine the injection characteristics of the fuel close to the actual conditions, it is not possible to set the exact expected value of the electronic controller.;Accordingly, the present invention is provided with a transmitter 24 for scanning a laser beam and a receiver 26 for receiving the laser beam on the cylinder wall of the engine combustion chamber 25 which is actually driven based on the accompanying drawings. The frequency of the laser beam transmitted to the data is converted into data by the converter 28 to obtain the set value of the electronic controller 18 by the computer 32.;Therefore, the present invention measures the particle size and speed of the fuel particles that are injected under the same conditions as in the actual operating state of the engine in the measuring apparatus to obtain a set value capable of injecting fuel from the injector 20 in an optimal state.
