8 Standization Test Procedure & Criteria Road Load Tire Condition Vehicle Pre-mileage Standization Test Procedure & Criteria Test Condition Lab Cooling Fan Slip Loadage

9 Standization Test Procedure & Criteria Load Road Passenger Vehicle Tire Condition Passenger Vehicle mileage Size Manufactor s specifications procedure Total 9section, average 90kph Repeating accel/decelation without cruise mode Pressure Standard air pressure Tread depth Over 50 % Cooling Fan Lab. Condition Cooling fan (fixed speed) Passenger Vehicle Opened Hood 2.5 m 3 /s Passenger Vehicle Temperature 20 ~ 30 C Attached As be released Cooling fan Closed hood About 30.5cm from front of Vehicle Fuel requirment Over 40 % Warm up Pre-driving with same mode

10 Standization Test Procedure & Criteria Load Road Passenger Vehicle Tire Condition Passenger Vehicle mileage Size Manufactor s specifications Even if Passenger vehicle s F.E. test procedure shall apply to HDV, Many Total 9section, component average 90kph still have to discuss. Pressure Standard air pressure procedure Mileage Repeating accel/decelation Tread depth Over 50 % without cruise mode Cooling fan (fixed speed) Cooling Fan(fixed or not, position, Fan capacity) Cooling Fan Lab. Condition Attached device Fuel requirement etc Passenger Vehicle Opened Hood 2.5 m 3 /s Passenger Vehicle Temperature 20 ~ 30 C Attached As be released Cooling fan Closed hood About 30.5cm from front of Vehicle Fuel requirement Warm up Over 40 % Pre-driving with same mode

11 Chassis Dynamometer Test Chassis Dynamometer for HDV Specification KATECH JIAT Picture Type MIM (Motor in the Middle) AC IGBT Vector Max test speed 160 km/h 150 km/h Inertia simulation range Max permissible axle load Vehicle cooling fan (Main) 3,500~30,000 kg 1,000~40,000 kg 20,000 kg 25,000 kg 64,000 m 3 /h 144,000 m 3 /h

12 Chassis Dynamometer Test Test condition & Procedure Pay Loadage considered slip Coast-down test & Pre-run WHVC Driving & Data analysis Measuring CO 2, 2~3 times repeated

13 Chassis Dynamometer Test(WHVC) Fuel Consumption by GVW CNG Truck 15 case (2.5~25t) Bus 8 case (city 4, express 4) Truck Bus(express) Bus(city) Most of all vehicles Fuel economy show linearity.
