Topic:Point of Contact:Test Objective:Induction System DepositFuel EvaluationRobert LeggPhone: (210) 522-2071Fax: (210) 522-4544The objective of this test is to evaluate the tendency ofmotor gasolines to form induction system deposits bysimulating carburetor spark-ignition engine conditions.Apparatus:Test Procedure:Fuel Requirement:Duration:Test Results:An induction system deposit bench rig is used for this test.The test procedure is as follows:1. A 100-ml volume of the test fuel is sprayed onto thedeposit tube – 50 minutes2. Heat soak and cooling time – 10 minutes3. If required, repeat with additional 100-ml volume oftest fuelThe fuel requirement for this test is 100 to 300 ml of fuel.The duration of this test is 1 to 3 hours.The test results are measured by the deposit weight gainon the deposit tube for every 100 ml of fuel.Note: This test is described in Federal Test Method 500.1.16SOUTHWEST RESEARCH INSTITUTESan Antonio, TexasJuly 2010
