Of the buyback, 138,000 had been completed by 18 February 2017 with 150,000 more to be returned. 52,000 chose to keep their cars. 67,000 diesel cars from model year 2015 were cleared for repairs, but left uncertainty about the future of 325,000 "Generation One" diesel VWs from the 2009–2014 model years, which use the "lean NO x trap" and ...
Early in the 1950s scientists discovered that vehicle emissions were a significant factor that had been causing the air quality to deteriorate. [8] This led to the introduction of vehicle emissions standards in California in 1966, furthermore due to the seriousness of the problem, in 1970 the Clean Air Act was introduced in order to regulate these standards all over the United States.

Diesels actually do not suffer exactly the same "knock" as gasoline engines since the cause is known to be only the very fast rate of pressure rise, not unstable combustion. Diesel fuels are actually very prone to knock in gasoline engines but in the diesel engine there is no time for knock to occur because the fuel is only oxidized during the ...
1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).
In a diesel engine, the torque and the rotational speed are controlled by means of quality torque manipulation. This means that, with each intake stroke, the engine draws in air which is not mixed with fuel; the fuel is injected into the cylinder after its contents have been compressed during the compression stroke. The high air temperature ...
1995 Cadillac Seville disengaged emissions controls whenever heat or air conditioning was on. In 1995, General Motors was ordered to recall 470,000 model year 1991 through 1995 Cadillacs and pay an $11 million fine for programming the car's electronic control unit (ECU) to enrich the fuel mixture any time the car's air conditioning or cabin heat was operating, since the EPA tests are conducted ...
Using car wax with UV protection can also help prevent car peeling. Hyundai owners who have experienced peeling white paint are encouraged to reach out to their local dealership for assistance.
Reasons for banning the further sale of fossil fuel vehicles include: reducing health risks from pollution particulates, notably diesel PM10s, and other emissions, notably nitrogen oxides; [8] meeting national greenhouse gas, such as CO 2, targets under international agreements such as the Kyoto Protocol and the Paris Agreement; or energy independence.
