To be eligible for thiscredit the high efficiency lighting must beinstalled in the following components:Parking/position, front and rearturn signals, front and rearside markers, stop/brake lights(including the center-mounted location), taillights, backup/reverse lights, and license platelighting.Honda Questions:• Is Baseline EPA’s data or previous model’s data• Require 60W AND named lights (Parking, Turn, Side, Brake/Stop)?Honda’s Proposal:1. EPA’s data should be the baseline.2. Any combination to reduce 60W load• Including High/Low Beams, OK tonot include some named lights3. Additional request to allow DRL• Honda considers DRL asa safety technology• Standard on every vehicle we sell (since 2006)• LEDs reduce workload.• Under test conditions – DRLs are turned off.41 – Example Calculation - ProposedLightingComponentEPABaseline NewCarRatioofVMT 50% 50%DRL 45.822.0100%0%11.9Lowbeam 112.466.00%91%21.1Highbeam 127.8110.00%9%0.8Parking/position 14.8 14.80%100% 0.0Turnsignal,front 53.6 53.6 5% 5% 0.0Sidemarker,front 9.64.40%100%2.6Stop 53.04.18% 8%3.9Tail 14.44.10%100%5.2CHMSL 17.71.58% 8%1.3Turnsignal,rear 53.6 53.6 5% 5% 0.0Sidemarker,rear 9.64.10%100%2.8Backup/reverse 35.4 35.4 1% 1% 0.0Licenseplate 9.62.00%100%3.8Total 183.2 105.5 53.3Day+NightTarget 30.0 1.1NewCar 178% 2.0grams/mileCO2creditNewCarEnergyNightuseDayTimeUse52 – Electrical Load Reduction – Light RelaysHonda Proposal• Lighting Relays consume power at the same usage rate as lighting.• By converting electro-mechanical to semiconductor relays, we can reduce powerconsumption.LightingComponent Baseline NewCarRatioofVMT 50% 50%DRL100%0%DRLRelay 1.30.05100%0%0.6Lowbeam0%91%LowbeamRelay 1.30.050%91%0.6Highbeam0%9%HighbeamRelay 1.30.050%9%0.1Turnsignal,front 5% 5%Turn/HazardRelay 1.30.055% 5%0.1Parking/SideMarker 0% 100%Park/SideRelay 1.30.050% 100%0.6Total 2.7 0.1 1.9Day+NightTarget 30.0 1.1NewCar 6% 0.1NewCarEnergyNightuseDayTimeUse62 – Other Relays?Honda Question:• Other Relays can reduce electric loads, however, we are unsure how tomeasure their impact:• Power window relay• Wiper motor relay• Power tailgate relay• Defroster relay• Seat heater relayHonda has lifetime usage “data” to determine durability standards. Could that bethe basis for discussion?73 – Engine Heat RecoveryDefinition“Engine heat recovery means a system that captures heat that would otherwisebe lost through the exhaust system or through the radiator and converting thatheat to electrical energy that is used tomeet the electrical requirements of thevehicle. Such a system must have a capacity of at least 100W to achieve 0.7g/mi of credit. Every additional 100W of capacity will result in an additional 0.7g/mi of credit.”Honda Comment• We want to confirm credit calculation for systems over 100W.Basic Credit Formula Concept = 0.007grams/mile-Watts x Capacity(W) ifCapacity > 100W1. If capacity is 150W, then Credit should be 150 x .007 = 1.12. Definition of system capacity• Peak value, Test cycle average value? Or ?• Honda recommends capacity should be based on5 cycle average valuebecause it encourages system design to be most efficient duringrepresentative driving.8DefinitionActive transmission warm-up meansa system that uses waste heatfrom the exhaust system to warm the transmission fluid to anoperating temperature range quickly using a heat exchanger in theexhaust system, increasing the overall transmission efficiency byreducing parasitic losses associatedwith the transmission fluid, suchas losses related to friction andfluid viscosity. (1.8 grams/mile)Active engine warm-up means a system using waste heat from theexhaust system to warm up targetedparts of the engine so that itreduces engine friction lossesand enables the closed-loop fuelcontrol more quickly. It would allow a faster transition from coldoperation to warm operation,decreasing CO2 emissions, andincreasing fuel economy. (1.8 grams/mile)Honda Proposal• Honda’s system design can effectively use one heater core toeffectively warm-up both theengine and the transmission systems.• Honda proposes to receive both credits for our one, advancedtechnology, integrated-designsystem. (3.6 grams/mile)4 – Active transmission warm-up / Active engine warm-up94 – Active transmission warm-up / Active engine warm-upDoes this baseline modeling assume linkedengine coolant loop to warm transmission?105 – Electric Heater Circulation PumpDefinitionElectric heater circulation pumpmeans a pump system installed in a stop-start equippedvehicle or in a hybrid electric vehicle or plug-in hybrid electric vehicle that continues tocirculate hot coolant through the heater core when the engine is stopped during a stopstart event. This system mustbe calibrated to keep the engine off for 1 minute or morewhen the external ambienttemperature is 30 deg F.Honda CommentIf a future start-stop + HVAC system is designed to maintain all heating functions for morethan 1 minute during the same test cycle described above, can that system earn the samecredits without an ElectricHeater Circulation Pump?1.0Electric Heater Circulation Pump2.9EPA3.9*Start-Stop SystemOEMPassenger Car* Start Stop system that meets criteria of Electric Heat Circulation Pump11DefinitionSolar reflective paint means a vehicle paintor surface coating which reflects atleast 65 percent of the impinging infrared solar energy, as determined usingASTM standards E903, E1918–06, or C1549–09. These ASTM standards areincorporated by reference; see§86.1.Honda Comment1. It is difficult for all colors to reflectat least 65 percent of the impinging infraredsolar energy. We think that we may install the solar reflective paint to only somecolors, and receive sales-weighted credits.6 – Solar Reflective Paint11/1212DefinitionEPA & NHTSA refer to total solar transmittance or Tts.Honda CommentLow Tts glass usually uses small metal flakes that can interfere with transmissionof radio signals in and out of the cabin– GPS– Cellphone– Garage Door Openers– Etc.If Tds or Direct Solar Transmittance can reduce interior cabin temperaturessufficiently, we believe some credit should be allowed for this technology.7 – Glass & Glazing (tts vs tds)139 – Review of the AHM Policy CommentsHonda Comments• Minimum Fleet Percentages for some technologiesHonda believes this will actually delay introduction of newtechnologies, not speed them up.The introduction is often pairedwith a) FMC timing, b) profit margin on a car, c) higher-end modelswith greater margin, lower volumes and therefore, lower risks.• Dealer-Installed Options:Dealers have a robust business installing options prior to sale. If theyinstall some GHG-effective device(like block heaters...), can theyearn credits.• US Production vs. US Sales (mistake?)• Support Application of off-cycle credits to 2012 – 2016 model years.Logic and rationale are the same...
