Abstract
A real-time mass flow measurement system that accurately measures fuel mass delivered to each cylinder per stroke of an injection pump or a fuel injector in an internal combustion engine. In accordance with preferred embodiment of the present invention, the mass flow measurement system and method includes a fuel measuring device that measures fuel delivered by one of the plurality of fuel injectors or fuel pumps. The preferred embodiment also includes a fuel transfer circuit for directing fuel flow to the fuel measuring device and a plurality of fuel diverting devices positioned along the fuel transfer circuit for diverting fuel flow from the plurality of fuel injectors or pumps into the fuel transfer circuit and a fuel routing device positioned along the fuel transfer circuit for routing the diverted fuel flow to either the fuel measuring device or a fuel drain. The mass flow measurement system further includes a data acquisition system including a digital computer and a flow controller for controlling the fuel routing device. The digital computer includes a software program for receiving operator input data, controlling the fuel diverting devices and obtaining measurement data fr…
