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 Ram 1500 with EcoDiesel was the first half-ton pickup with a diesel engine available in the U.S since Dodge had previously offered a six-cylinder Mitsubishi diesel in its half-ton pickup for 1978, and GM offered diesel engines from 1978 to 1998. [10] Other diesel pickup trucks that have been available for decades are heavier-duty trucks ...
The Urban Dynamometer Driving Schedule is a mandated dynamometer test on tailpipe emissions of a car that represents city driving conditions. It is defined in 40 CFR 86.I. [2] [3] It is also known as FTP-72 or LA-4, and it is also used in Sweden as the A10 or CVS (Constant Volume Sampler) cycle and in Australia as the ADR 27 (Australian Design ...
Newsom's office said Stellantis will avoid adding up to 12 million metric tons of greenhouse gas emissions through 2026, which is equivalent to emissions from more than 2.3 million vehicles annually.
A new emissions rule for cars, trucks and vans sold in the United States from 2027 to 2032 will phase reductions in more slowly to allow charging infrastructure and low-carbon emissions vehicles ...
The "Drive-cycle" basically is the representative of the road. Drive cycles are used to reduce the expense of on road tests, time of test and fatigue of the test engineer. The whole idea is to bring the road to the test lab (a chassis dynamo-meter) or to the computer simulation. Two kinds of drive cycle can be made.
BMW was implicated in an "emissions cartel" which sought to restrict design standards for AdBlue. They were fined €875m along with VW in July 2021. [23] In 2018 BMW recalled 11,700 cars which had incorrect emissions software installed to some diesel cars. The company denied using defeat devices, as suggested by the KBA. [24]
UK researchers at Loughborough University and the University of Sussex concluded that waste heat from light-duty vehicle engines in a steam power cycle could deliver fuel economy advantages of 6.3% – 31.7%, depending upon drive cycle, and that high efficiencies can be achieved at practical operating pressures.
