These tests can take place at the research and development stage, in use
at service centres or at the end of a production line at a factory.
Lubricant manufacturers also carry out their own testing when developing
number of different engines will be tested on the same test bed, the
exhaust system back pressure needs to be adjusted.
little back pressure and the exhaust will become noisy and too much back
pressure will cause harmful effects to the engine including shortening
exhaust valve and turbocharger life.
Controls manufactures the Z Series butterfly valve to simulate and
adjust the effective back pressure of the test bed exhaust system.
units are frequently electrically or pneumatically actuated, receiving
4-20mA signals from the control system and generating 4-20mA signals for
the data acquisition system.
