EMISSION PROBE PARTS
TUBE:
3/8” OD x 0.049 wall Stainless Steel
Length determined by pipe diameter and placement of connecting end to allow easy connection of the heated sample line. Long tubes may be bent to place connection end in desirable location.
3/8 Nut-Ferrule sets(Swagelok SS-600-NFSET)
Probe Adapter: Swagelok fitting SS-600-1-4BT(3/8 NPT to 3/8 Tube, Bored Through)
Cap Tube with Swagelok Cap SS-600-C (if keeping probe installed)
Or
Plug Adapter with Swagelok Plug SS-600-P (if probe is removed)
45o Mitered End
EMISSION PROBE INSTALLATION
Scribe Line to Identify
45o Mitered Face
Weld/braze adapter fitting to exhaust pipe
(Do NOT use epoxy as shown in this mock-up)
Mitered face in center of pipe and facing upstream
Check the rules regarding probe locations. The probe can NOT be located near the end of the pipe as shown in this mock-up
COUPLER ORIENTATION
For all Quick Disconnect couplers (fuel, coolant, supply, return);
Flow is out of the male coupler and into the female coupler.
NOTE: Contact [email protected] to request couplers (provided free of charge to registered teams).

COOLANT COUPLERS
The black, Coolant Couplers shown above have been discontinued. New couplers, white, slightly smaller, and also with a ¾” hose barb, MUST BE USED. The new couplers will not mate with the old style couplers. For information on the new HFC couplers: http://www.colder.com/Products/tabid/693/Default.aspx?ProductId=14
Hot Coolant from Engine into Heat Exchanger
Cooled Coolant into Engine
Inlet line and Outlet line are each 80” long
Closed Loop Engine Cooling System
Utilizing a brazed plate Heat Exchanger
(Closed Loop = Pressure can build up to radiator cap’s relief pressure)
Cold Side of Heat Exchanger
Temperature Regulating Valve opens based on the temperature of the coolant returning to the engine

Test Facility Responsibility
FUEL SYSTEM for EMISSION TESTINGThe sled’s fuel tank must be disconnected so that the test facility’s fuel measuring system supplies all the fuel. The test facility will supply a low pressure fuel. Teams need to supply their own external fuel pump and regulator to ensure that the engine receives fuel at the correct pressure.
Teams must have the Colder Quick Disconnects installed for both emission events. For the in-service emission event, take into consideration accessibility of the QD’s and routing of the external fuel line(s). The QD’s are not required during the other events in the competition.
Questions regarding the emission fuel system requirements should be directed to [email protected].

During the In-Service Emission Event The facility's fuel lines must run from the engine to the emission test sleigh
Fuel Couplers should be located to provide easy access and allow the cowling to be closed during the In-Service emission test.
