1 The following fuel hose standards also apply to auxiliary engines on SIMW using > 30 kW SIME. The fuel hose permeation standards do not apply to under the cowl fuel lines. As an alternative to 40 C.F.R., § 1060.515 (2008), component manufacturers can test following SAE, Test Procedure to Determine the Hydrocarbon Losses from Fuel Tubes, Hoses, Fittings, and Fuel Line Assemblies by Recirculation (May 2013), SAE J1737. | ||||||||
2a Reactive Organic Gas (ROG). | ||||||||
2b Hydrocarbon (HC). | ||||||||
3 For non-canister vented systems, a venting control efficiency standard of 65 percent must be met. To determine the venting control efficiency, a venting control test must be performed following 40 C.F.R., § 1060.525 (2008), (or TP-1503, if applicable) with E10 CERT fuel and then compared against an identical uncontrolled venting test. Alternatively, an estimate of uncontrolled venting can be calculated using the fuel tank vapor generation equation (6) in Reddy, Prediction of Fuel Vapor Generation from a Vehicle Fuel Tank as a Function of Fuel RVP and Temperature (Nov. 2004), SAE Technical Paper Series 892089. | ||||||||
4 Grams of vapor storage capacity per gallon of nominal fuel tank capacity. | ||||||||
5 Grams per liter of carbon working capacity with minimum carbon volume of 0.040 liters per gallon of nominal fuel tank capacity. The carbon canister must have a minimum effective length-to-diameter ratio of 3.5 and the vapor flow must be directed with the intent of using the whole carbon bed. | ||||||||
6 Starting with MY 2018 and thereafter, if the Executive Officer determines that all of the following criteria are met: | ||||||||
1. That a 5.0 g/m2/day fuel hose has been certified, and | ||||||||
2. That a certified 5.0 g/m2/day fuel hose is commercially available in common sizes, then the fuel hose permeation standard will change to 5.0 g/m2/day, effective no earlier than MY 2020 or two years after the finding. | ||||||||
7 Using a test temperature of 40°C. As an alternative to 40 C.F.R., § 1060.515 (2008), component manufacturers can test following SAE, Test Procedure to Determine the Hydrocarbon Losses from Fuel Tubes, Hoses, Fittings, and Fuel Line Assemblies by Recirculation (May 2013), SAE J1737. | ||||||||
8 Using a test fuel of either E10 CERT or CE 10. As an alternative for fuel tank testing, component manufacturers can certify at 1.4 grams/m2/day at 40°C. | ||||||||
9 Using E10 CERT fuel. | ||||||||
10 ASTM, Standard Test Method for Determination of Butane Working Capacity of Activated Carbon (2010), ASTM D5228-92, West Conshohocken, PA; | ||||||||
11 As an alternative to TP-1503 testing for pressure relief valves, component manufacturers can perform a leak test performance test of the pressure relief valve following TP-1505. A SIMW using a sealed evaporative control system to a positive pressure of at least 7.35kPa (1.05 PSI)] will be deemed compliant with the 65 percent HC reduction requirement. The pressure relief valve must also be tested and pass TP-1505 durability requirements. |
