1.1 This test method coves an engine dynamometer test procedure for evaluation of intake valve deposit formation of unleaded spark-ignition engine fuels. This test uses a Ford Ranger 2.3 L four-cylinder engine. The following details the procedure, hardware, and operations used for this test.

1.2 The ASTM Test Monitoring Center (TMC) is responsible for engine test stand certification as well as issuance of information letters after test method modifications are approved by Subcommittee D02.A and Committee D02. Users of this test method shall request copies of recent information letters from the TMC to ensure proper conduct of the test method.

1.3 The values stated in SI units are to be regarded as the standard. Approximate inch-pound units are shown in parenthesis for information.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine applicability of regulatory limitations prior to use. Specific precautionary statements are given throughout this test method.
