Lean Oxygen Gum Simulation Test for Gasoline Detergency and its Correlation with M111 Engine Test 2010-01-2134
Gasoline detergency is related to deposits at various parts of
the engine and therefore has impact on vehicle driveability and
emission properties. The widely used engine tests such as CEC F-20
M111 and ASTM D6201 Ford 2.3L tests take tens of hours and thus are
very expensive and time consuming to carry out.
A new simulation test for gasoline detergency on intake valve
cleanliness using lean-oxygen gum method was developed and the
correlation of test results with M111 engine test was studied.
Gasoline samples with different detergency levels were tested with
both the lean-oxygen gum method and the M111 engine test. Test
results of 24 gasoline samples show satisfactory correlation
between the lean-oxygen gum method and the M111 engine test
