The Worldwide Harmonised Light vehicles Test Procedure (WLTP) [1] is a global driving cycle standard for determining the levels of pollutants, CO 2 emission standards and fuel consumption of conventional internal combustion engine (ICE) and hybrid automobiles, as well as the all-electric range of plug-in electric vehicles.
The "city" driving program of the EPA Federal Test Procedure is identical to the UDDS plus the first 505 seconds of an additional UDDS cycle. [5] [6] EPA FTP-75 driving cycle. Then the characteristics of the cycle are: Distance travelled: 11.04 miles (17.77 km) Duration: 1874 seconds; Average speed: 21.2 mph (34.1 km/h)
A driving cycle is a series of data points representing the speed of a vehicle versus time.. Driving cycles are produced by different countries and organizations to assess the performance of vehicles in various ways, for example, fuel consumption, electric vehicle autonomy and polluting emissions.
For each vehicle configuration, a look-up table is applied: each speed corresponds to a certain value of resistance (reverse torque applied to the drive wheels). This arrangement enables the use of a single physical vehicle to test all vehicle body styles (Sedan, hatchback, MPV etc.) by simply changing the look-up table. A fan is coupled to the ...
Since 1 April 2018, Euro 4, Tier 2, and EPA 2007 are mandated in Peru. [83] Since 8 October 2018, all new petrol cars in Indonesia must comply with Euro 4. [84] Since 1 July 2019, all new heavy vehicles in Mexico must comply with EPA 07 and Euro 5. [85] Since 1 April 2020, all new 2, 3 or 4-wheelers in India must comply with BS VI (similar to ...
The China Light-Duty Vehicle Test Cycle (CLTC) (Chinese: 中国轻型汽车行驶工况; pinyin: Zhōngguó qīngxíng qìchē xíngshǐ gōng kuàng) is a driving cycle standard introduced by the government of China to measure the energy consumption, driving range and emissions of light-duty vehicles, including both internal combustion engine (ICE) vehicles and electric vehicles (EV).
The Clean Air Act of 1963 (CAA) was passed as an extension of the Air Pollution Control Act of 1955, encouraging the federal government via the United States Public Health Service under the then-Department of Health, Education, and Welfare (HEW) to encourage research and development towards reducing pollution and working with states to establish their own emission reduction programs.
Turkey is planning to use the worldwide harmonized light vehicles test procedure (WLTP). [ 49 ] However, despite these tailpipe emission standards for new vehicle types there are many older diesel vehicles, [ 50 ] no low-emission zones and no national limit on PM2.5 particulates so local pollution, including from older vehicles, is still a ...
