Emissions regulations and the term of enforcement. ・ THC in Class 1 and 2 is more stringent than that of Euro4. ・ Class 3 is the same as the new Euro4 (considered harmonization)

3 Type II – emissions test (Idle/high Idle) 3 JapanEURO4 IDLECO3.0% the values measured in accordance with point 4.2.3. shall be in compliance with the requirements set out in points 8.2.1.2. of Annex II to Directive 2009/40/EC if point 8.2.1.2. (a) is selected by the manufacturer, the specific CO level given by the manufacturer shall be entered on the certificate of conformity; ・・・・・ HC ≦ 125cc 1600ppm >125cc 1000ppm High IDLE CO ↑ HC Limit Value

10 For exposed type fuel tanks: Tf = 0.3333.t + 288.5 Tv = 0.3333.t + 294.0 For non-exposed type fuel tanks: Tf = 0.2222.t +288.5 Tv = 0.2222.t + 294.0 where: Tf = required temperature of fuel (K); Tv = required temperature of vapor (K); t = time from start of the tank heat build in minutes. Fuel Tank heating profile for DBL test Japan will apply the same heating profile as EURO4 and considers to add the definition of “Non-exposed type fuel tanks”. Definition The "non-exposed fuel tank", all parts of the fuel tank, including the fuel tank cap, fuel tank placement and structure that is not subject to direct sunlight, Or, it is proved that the handle manufacturing is equivalent to "non-exposed fuel tank" means a fuel tank Examining Authority recognized.

12 Type VIII – J-OBD1 12  Basically, OBD in the Japan 2016 regulation is to monitor the malfunctions of the following components caused by an open/short circuit. - Barometric pressure sensor - Manifold absolute pressure sensor - Intake air temperature sensor - Engine coolant temperature sensor / Engine temperature sensor - Throttle position sensor - Camshaft position sensor - Crankshaft position sensor - O2 sensor - O2 sensor heater - Ignition coil primary control circuits - Secondary air injection system  Fuel system Monitoring requirements

13 Type VIII – J-OBD1 13 Functional requirements  Malfunction information to be stored in the on-board ECU  Malfunction indicator light to be in conformity with ISO 2575  Data link connector between the vehicle and the diagnostic tester to be in conformity with ISO 15031-3 (SAE J1962) An alternative connection interface may be used when the vehicle manufacture prepares an adapter which enables connection to the diagnostic tester conforming with ISO 15031-3 (SAE J1962) Specific connector by each manufacture - Small size - Waterproof ECU ISO 15031-3 (SAE J1962) -Big size -Non waterproof Adaptor
