APPARATUS FOR MEASURING EXHAUST FLOWRATE USING LAMINAR FLOW ELEMENT |
摘要 |
An apparatus for determining the exhaust flowrate from an internal combustion engine (112) includes a laminar flowmeter (116). The flowmeter includes a capillary section (18) of ceramic material including an array of capillary tubes. Signals from a differential pressure sensor (128) which measures pressure loss across the capillary section as well as an absolute pressure sensor (126) and a temperature sensor (130) are input to a computer (134). The computer is programmed to calculate the flowrate of exhaust gas from the engine through its operating range.
