1、California Air Resources Board (ARB)SAND CAR EMISSIONS CERTIFICATIONOctober 24, 2006,2,Major Steps,(New Mfrs.) Register with the U.S. EPA and ARB.Group vehicles into engine/evaporative families.Demonstrate useful life (UL) durability & emissions compliance for each family.Submit Applications to U.S.

2、 EPA and ARB via the Internet.,3,Major Steps (contd),Receive Certificate of Conformity from U.S EPA and Executive Order (EO) from ARB.Produce and label each vehicle according to specifications described in applications.Do not introduce vehicles into commerce in CA until certified with EOs.Receive U.

3、S. EPA and ARB approval for any emissionsrelated production running changes.,4,New MFRs Getting Registered,Register with U.S. EPA as a MFR.ARB issues its Executive Orders (EOs) to the vehicle MFR. A business entity that has complete knowledge and control of the vehicles specifications may certify on

4、 behalf of a MFR.ARB does not issue EOs to importers nor dealers that do not meet the above criteria.,5,New MFRs Getting Registered (contd),Submit to ARB via regular mail a hard copy “Letter of Intent” to certify vehicles in CA.ARB sends the applicant an Excel template to be completed. Contact infor

5、mation, i.e., name, address, phone number, etc. Vehicle type(s) you intend to certify, i.e., sand car, ATV, OFMC U.S. EPAs 3-character mfr.s code Mfr.s name, or business entitys name for which EO is issuedARB assigns unique ARB mfr.s code to enable access to E-Cert & EDMS.,6,Certifying Manufacturers

6、 A sand car must comply with exhaust and evaporative standards. A sand car is certified as a vehicle by testing using either the chassis or optional engine test procedures.Option 1: Sand Car OEM A produces the engine and chassis - A is the certifying MFR carrying all compliance obligations and liabi

7、lities.,7,Certifying Manufacturers (contd) Option 2: Sand Car OEM B buys complete engines from Engine OEM C and builds own chassis- B is the certifying MFR carrying all compliance obligations and liabilities. (Mfr C can support mfr B by providing durability and emission data, AECD and adjustable par

8、ameter info, production running change info and test data, and by implementing any required corrective action for in-use noncompliance.),8,Certifying Manufacturers (contd)Option 3: Engine OEM D has a close business relationship with, and supplies complete engines to, Sand Car OEMs E, F and G- D is t

9、he certifying MFR using the engine test option and carrying all compliance obligations and liabilities. D must include vehicle specifications, and fuel and evaporative systems for sand cars from E, F and G in its application. E, F, and G do not need to recertify.,9,Group Vehicles into Engine/Evapora

Durability DemonstrationMfr. proposes a durability test

12、 procedure to demonstrate emissions compliance with the standards for the vehicles useful life (UL) (5 years or 10,000 km.) If the test duration is less than the UL, the mfr. must justify how this duration correlates to real world vehicle usage.,11,Demonstrate UL Durability & Emissions Compliance (c

13、ontd),1. a. Durability DemonstrationItems to describe:Test duration (km or hours) Driving cycle or engine dynamometer cycle Test points & number of tests Recommended minimum of three test points If there is scheduled maintenance during the test cycle, an emission test before and after the maintenanc

14、e must be performed Test fuel(s) (service accumulation & emission tests) Maintenance schedule as given in the owners manual,12,Demonstrate UL Durability & Emissions Compliance (contd),1. b. Test worst case configuration vehicle in engine family, i.e., the configuration which has the greatest probabi

15、lity of exceeding the standards. Highest fuel flow rate Highest test vehicle weight Highest engine speed vs. vehicle speed (N/V) Transmission type, i.e., manual vs. automaticUnscheduled maintenance must be approved by ARB.All test data and projected emissions must be below applicable standard.,13,De

Determine UL deterioration factors (DFs)DF = B = projected emissions UL mileage_ _ _ _ _A interpolated emissions last test mileage,B,A,A,A =actual emission last test mileage A=interpolated emission last test mileage B =projected emission UL,1

17、4,Demonstrate UL Durability & Emissions Compliance (contd),2. Certification emission level, all pollutants A x DF standardactual emission last test mileage x DF standard3. Retain test vehicle for possible confirmatory testing at ARB and for testing future production running changes.,15,Adjustable Pa

18、rameters Fuel & Ignition System1. Adjustable parameters (e.g., idle air fuel mixture):Should employ measures approved by ARB to discourage adjustments by owners. Plugs Limiting CapsMust be described in application.2. ARB can specify, for emission testing, any setting within the physical range of adj
