T/AHEMA 17-2022 Rules and Methods for Exhaust Smoke Inspection of Non-road Mobile Diesel Machinery (Forklift)
Basic Information
Scope
Main Technical Content: The basic requirement is that the equipment under inspection must meet the safety performance requirements of relevant safety technical specifications or standards. The equipment under inspection should be fully preheated and in a normal operating state. Before the inspection, the exhaust system should be flushed using three free acceleration processes or other equivalent methods. For hybrid diesel forklifts, the exhaust smoke emission test should be conducted in diesel engine mode. **External Inspection**: The main content of the external inspection should include, but not be limited to, the following: a) Whether the inspected vehicle exhibits severe black smoke emissions; b) Whether the exhaust pollution control devices are complete and functioning properly; c) Whether the inspected vehicle is in good working condition; d) Whether the vehicle's instrumentation is functioning normally; e) Whether auxiliary equipment such as the heater and air conditioner powered by the diesel engine are turned off; f) Whether there are leaks in the diesel engine's intake and exhaust systems; g) Whether there are obvious liquid leaks in the diesel engine system; h) Whether there are mechanical faults that may affect safety or cause test deviations. For items (a) and (b) in the above inspection content, they are disqualifying items. As long as one of them fails, the external inspection is deemed unqualified and the inspection ends. The remaining external inspection items will be inspected based on the actual situation of the vehicle, and the actual situation will be recorded on-site. If the inspectors find any major issues affecting exhaust smoke emissions, the vehicle will be deemed unqualified and the inspection ends. For vehicles that fail the exhaust smoke emission test, the user can repair or carry out exhaust gas treatment before reapplying for inspection. **Inspection Methods**: 6.3.1 Zeroing: Before the Lingeman blackness
