The vehicle is run 10,000 test miles with daily mileageaccumulation of 800 miles.2. A fixed route is run, consisting of:• 10 percent city• 20 percent secondary road• 70 percent highway3. Intake valves are weighed.The fuel requirement for this test is 500 gallons of fuel.The duration of this test is 4 weeks.The test is a PASS if the average intake valve depositweight is less than 100 milligrams per the four valves forEPA requirement and less than 50 milligrams per valve forCARB requirement. CARB also requires a combustionchamber deposit (CCD) weight determination and limitsthe level to 1,300 mg average or 140% as compared to abase fuel result.This test is run as a CARB procedure and as an EPAprocedure following ASTM Method D-5500.7SOUTHWEST RESEARCH INSTITUTESan Antonio, TexasJuly 2010
