ABSTRACT
Knowledge about atomizers is obtained through laboratory investigations. There are two types of atomizer investigations: quality control tests and laboratory investigations. These tests are conducted by manufacturers and users of atomizers. The inspections in the factories are to verify the specifications of atomizers and detect production defects. Laboratory investigations of continuous atomizers are very diverse because they concern atomizers of various types. The most important aim of the laboratory investigations is to improve existing atomizers and develop new varieties and types of atomizers. Operation of atomizer in the tester and in the engine differs significantly. The flow rate of atomized liquid is usually measured together with other parameters. Proper operation of a multicylinder piston engine requires that injectors with identical flow rates be used. For the measurements a dyed liquid is used and drops are captured on equally spaced measuring devices such as plates, glass vessels, or ribbons of white paper.
