Implementing method for conducting Real Driving Emission

2013-02-22 What is the new WLTP cycle? The new tests measure fuel consumption, carbon dioxide (CO2) emissions, nitrogen oxides (NOX), carbon monoxide (CO) and particulates by mass and number (PM and PN). WLTP: Test cycle: Single test cycle: Dynamic cycle more representative of real driving: Cycle time 20 minutes: 30 minutes: Cycle distance: 11 kilometre: 23.25 kilometre: Driving phases: 2 phases, 66% urban and 34% non-urban driving: 4 more dynamic phases, 52% urban and 48% non-urban: Average speed: 34 kilometre per hour: 46.5 kilometre per hour: Maximum speed Since 1 September 2017, WLTP (Worldwide Harmonized Light-duty Test Procedure) has been progressively replacing the NEDC (New European Driving Cycle) for type 2020-04-27 European law means that WLTP (Worldwide Harmonized Light Vehicles Test Procedure) is the new laboratory test used to measure fuel consumption and CO2 emissions, which replaced the old NEDC (New European Driving Cycle) test procedure in September 2017. 2021-04-07 2018-10-02 The new WLTP driving cycle takes into account situations that are closer to everyday life than the NEDC standard. It allows you to assess daily consumption better. The Worldwide Harmonized Light Vehicle Test Procedure (WLTP) was introduced on September 1st, 2017 for new vehicle types.

Cycle distance: (NEDC: 11 km/ WLTP: 23.25 km). Average speed: (NEDC: 34 km per hour/ WLTP: 46.5 km per hour). Maximum speed: (NEDC: 120 km per hour/ WLTP: 131 km per hour). WLTP Cycle adapted to brakes –Main features PMP working group defined a Brake WLTP cycle for the brake particle emissions measurement: modification from the current exhaust emission test procedure. 10 Phases Soak times between phases Effective cycle time = 15816 s (4.4h) Total hours = 41h (PMP) Total n°STOPs = 303 PUBLIC INTERNAL CONFIDENTIAL SECRET The objectives of the Development of the worldwide Harmonized test Cycle (DHC) group under the WLTP informal group are to develop a world-wide harmonized light duty driving test cycle (WLTC) which represents typical driving characteristics around the world … Each drive cycle must include speed-vs-time data.

Request PDF | Recommendations for the new WLTP cycle based on an analysis of vehicle emission measurements on NEDC and CADC | Past investigations  WLTP was developed with the aim of being used as a global test cycle across different world regions, so pollutant and CO2 emissions as well as fuel/energy  Worldwide Harmonized Light Vehicle Test Procedure (WLTP) extra-urban, combined) - the WLTP driving cycle is divided into four parts with different average  WLTP will replace the previous fuel economy testing, known as the New European Driving Cycle (NEDC), which was introduced back in 1992. Since September  WLTP or Worldwide Harmonized Light Vehicles Test Procedure - · WLTP: What is it all about? · What is different in the wltp test cycle procedure?

Basically, the WLTP test takes place over a longer distance than the outgoing NEDC test, using higher top and average speeds, and lasting a greater amount of time. And unlike the NEDC test, the impact of all available optional equipment – such as bigger wheels or panoramic sunroofs – is considered in the WLTP cycle.

La procedura di prova per veicoli leggeri armonizzata a livello mondiale comunemente chiamata WLTP (Worldwide harmonized Light vehicles Test Procedure) definisce una norma armonizzata globale per determinare i livelli di inquinanti ed emissioni di CO 2, consumo di carburante o di energia e gamma di veicoli elettrici leggeri (autovetture e furgoni commerciali leggeri).

Going into the details, WLTP is the acronym of Worldwide (harmonized) light (vehicles) test procedure, that is a test procedure also intended for light The new WLTP laboratory test cycle is longer than the NEDC cycle in both time and distance - cars are now driven for 30 minutes and around 14 miles, compared to 20 minutes and less than seven miles. The New European Driving Cycle (NEDC) and the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) are two type approval tests with the same purpose: to measure regulated pollutants and particle matter emissions, as well as fuel consumption on new cars.
