Engine manufacturer Cummins Inc. has agreed to pay a $1.675 billion penalty for allegedly installing "defeat devices" on approximately 1 million pickup trucks to cheat emissions tests.
On 10 October 2015, Consumer Reports tested a 2015 Jetta TDI and a 2011 Jetta Sportwagen TDI in what they presumed was the special emissions testing, or cheat mode. The 0 to 60 mph (0 to 97 km/h) acceleration time of the 2011 Jetta increased from 9.9 to 10.5 seconds, and the 2015 car's time went from 9.1 to 9.2 seconds.
The claimed defeat devices include a Bit 15 mode to switch off emissions control after 16 miles of driving (the length of an official U.S. emissions test), and Slipguard which tries to directly determine if the car is being tested based on speed and acceleration profiles. [16] [17] [18]
Only state which still conduct emission testing dating back to the 1967 model year unlike other states using EPA classification (a few still conduct test for 1968–present (1968+ testing is for jurisdictions using defined EPA standards for vehicle classification since the '68 model year and beyond automobiles must have an exhaust emission ...
The most recent two model years of vehicles are exempt from emissions testing. [38] Massachusetts – annually, as of 2008. Vehicles less than 15 years old must pass an OBD-2 scan for emissions system compliance. Vehicles over 15 years old receive a visual check and must not 'produce visible smoke'.
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections .
In 1998, a Swedish researcher criticized the New European Driving Cycle standard for allowing large emission differences between test and reality. [81] The Washington Post also reported that in the late 1990s, EPA engineers at Virginia Testing Laboratory had built a system called ROVER, designed to test a car's emissions on the road. The ...
The increase will be the first for Cheat Lake customers since 2014 and will finance improvements to MUB's Cheat Lake Wastewater Treatment Plant. The project, which will increase the plant's ...
