Summary:

AbstractThe analysis of pressure losses in the cylinder head of an engine, which can compromise up to 70 % of engine efficiency is accomplished by a device called a flow bench, to evaluate the variation in flow and pressure between the inlet and outlet of the cylinder by reading in measurement instruments typically water column manometer. The paper describes the methodology used in the automation of a flow bench. A printed circuit containing pressure transducers (absolute pressure sensor to intake manifold) that send electrical to a microcontroller (Arduino) signals and is shown on an interface card was drawn. For temperature we opted for the use of a digital sensor with smaller margin of error for the same price (compared to analog sensor). The level of the valve is done by a digital caliper. In man machine interface are indicated test pressures and the percentage of flow, temperatures at admission and exhaust are indicated as well as the calibrated orifices are open. The system automatically calculates the flow for each valve lift position and also allows the flow rate to be measured through the use of Pitot tubes. You can choose the units employed, either in English units and the international system of measurement beyond the instantaneous generation of graphics directly on the computer
