36 HOW TO CONTROL 50:50 MIXTURE? REGULATED STANDARS FOR VAPOR MIX GTR-19 Procedure After the temperature conditioning test and vibration test, the canister shall be aged with a mixture of Type 1 E10 market fuel as specified in paragraph of this annex and nitrogen or air with a 50 ± 15 percent fuel vapour volume. The fuel vapour fill rate shall be kept between 60 ± 20 g/h. The canister shall be loaded to the corresponding breakthrough. Breakthrough shall be considered accomplished when the cumulative quantity of hydrocarbons emitted equals 2 grams. CARB Bleed Emission Test Procedure III.D Carbon Canister System Purge/Load Cycling with Fuel Vapor. The carbon canister system shall be cycle aged no less than 10 cycles using the gasoline referenced in section III.D by loading the canister system to 2-gram breakthrough with either a mixture of fuel vapor and nitrogen (50 ± 15 percent fuel vapor by volume) or a mixture of fuel vapor and air (50 ± 15 percent fuel vapor by volume), at a fuel vapor fill rate of 40 to 80 grams per hour. Each loading is followed by purging the canister system with 300 canister bed volume exchanges at 0.8 cfm. How to control and measure the fuel vapor/n2 mixture?

62 SHED TESTING SOLUTIONS & TRENDS Since the initial start of evaporative emission rules 1970 in California, the regulation trends and demands did not change much in the last decades. In the last 2-3 years, the awareness of the entire evaporative testing capabilities changed. Various reasons e.g. new test sequences, stricter emission limits, additional CO2 targets, bio-fuels and new vehicle drive technologies forces the OEM s and component manufacturers to invest into new equipment and testing solutions. Know-how, long-term experience and a complete product and solution portfolio is key to achieve best test data quality, reliability and global correlation targets. Traditional Standard Testing Setup Single device supplier System design on demand of OEM or homemade solution Local supplier Supplier trained by customer Development try & error Single test report Newest Testing Solutions & Trends Global solution partner providing a complete product and application portfolio Industrialized standard products fulfilling global demands in terms of safety and operation standards Global accountable partners for sales, service and application support Development partnership with specific testing expertise between supplier and customer Simulation services and R&D partner for e.g. flow and temperature simulation for vehicle and UUT Vehicle testing and certification workbook Entire workflow data and test results including information of soaking, fueling, canister conditioning, prep-cycles, Hot-Soak + Diurnal testing, etc. Manual single test operation and data handling C entralized data and workflow management Hard-coded test sequence Flexible and dynamic test configuration with multiple template and stencil database Fixed volume SHED VV/VT-SHED including an additional volume reduction BAG for improvement of the analytical response up to 25% Manual refueling operation Supplier of environmental chambers Personnel attention during test runs required Trends Remote controlled automatic ORVR test procedure with online-data validation Expert in analytical emission testing, long-term experience in FID technologies with clear understanding of the relationship and dependencies between exhaust emission and evaporative emission testing (thermal management of vehicle - depends on CD test cell design) Unmanned operation 24/7, un-limited days (long-term diurnal testing) Live Webinar - EVAPORATIVE EMISSIONS Patrick Ulmerich / Michael Scheytt 11.

63 CANISTER TESTING SOLUTIONS & TRENDS Beside the general various market trends(see SHED Testing Solutions & Trends), the RDE (Real Drive Emissions) discussion being more realistic are pushing the entire testing and simulation environment to higher level of flexibility and functionality to fulf ill future demands of - vehicle and device testing, certification and development. Local emission levels and problems are forcing governments to modify or create their individual legal emission regulation tar gets (e.g. China, Beijing) with possible consequences like: Extended temperature and humidity simulation (canister purge air) Dynamic (acc. Drive cycles) canister purge procedures (not just stationary) Dynamic load simulation (not just stationary) Combined canister stabilization and conditioning procedures Real vapor conditioning (instead of synthetic gas conditioning - C4H10 / N2) Improved accuracy, repeatability and control modes, Adv. PID loading control f(rvp, T, Q, m) Additional COP demands Advanced module testing e.g. fuel storage leak check procedure (acc. EPA ) OBD validation and simulation functions Long-term durability testing and in-use test cases Online data calculation and validation(not just cyclic results) Specific R&D tools and functions for example hybrid flow simulation pressurized tank systems puffer control purge control simulation and test, boost pump interfaces purge efficiency interface, pulsed inline heater control Actual testing setups covering most of the actual legal requirements but are they ready for future technologies, testing trends and emission visions?
