WLTP - Worldwide Harmonized Light Vehicle Test ProcedureINTRODUCTION The CO2 and fuel economy figures quoted are sourced from official regulated test results obtained through laboratory testing. They are for comparability purposes only and may not reflect your real driving experience, which may vary ...
emission test bench,using orthogonal design method to arrange test program and according with the relevant national standard make dynamic emissions performance test at a domestic vehicle diesel engine,analyze and process the test results,which provides a systematic research method for test design of ...
locations since the late 1990s.9,10,11In contrast, in the EU the New European Drive Cycle (NEDC) and test procedure did not fully reflect on-road emissions, and the decrease in NOxemissions from diesel vehicles in the real world has been less than expected based on emission standards as ...
If the vehicle under test is physically large, it may be necessary to measure in multiple locations to ensure that the entire vehicle area is captured within the 3 dB beamwidth of the antenna. This is a particular concern when measurements are being performed at a 3 m test dis...

In California, the transportation sector contributes to approximately 50% of total greenhouse gas (GHG) emissions and 90% of diesel particulate matter (PM) pollution1. Unlike internal combustion engine vehicles (ICEVs), zero-emission vehicles (ZEVs) produce no tailpipe emissions and only generate ...
“a representative value that attempts to relate the quantity of a pollutant released to the atmosphere with an activity associated with the release of that pollutant.” (Cheremisinoff, 2011). Adynamometertest usually provides the emission factor for each vehicle type in gram per kilometer, gram ...
