Diesel engine runaway: Diesel engine power is governed by the amount of fuel supplied. Excessive pressure in the crankcase can force mist of engine oil into the intake manifold, which can be burned in the same fashion as Diesel fuel, thus causing runaway. One-pedal driving mode and lack of brake application in deceleration and reverse actions. [16]
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 fuel economy of the 2011 car decreased from 50 to 46 mpg ‑US (4.7 to 5.1 L/100 km; 60 to 55 mpg ‑imp) and the 2015 car's fuel economy decreased from 53 to 50 mpg ‑US (4.4 to 4.7 L ...

Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.

Dieseling or engine run-on is a condition that can occur in spark-plug-ignited, gasoline-powered internal combustion engines, whereby the engine keeps running for a short period after being turned off, drawing fuel through the carburetor, into the engine and igniting it without a spark.
The National Transportation Safety Board has recommended that all new automobiles come equipped with technology meant to make speeding difficult or impossible, a move that comes after an accident ...
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. [1] [2] [3] Fuel consumption and emission tests are performed on chassis dynamometers. Tailpipe emissions are collected and measured to ...
These new issues, first estimated to cost up to €2 billion to repair, involved mainly diesel, but also some petrol models, with initial estimates suggesting that approximately 800,000 vehicles equipped with 1.4, 1.6 and 2.0 litre motors from VW, Skoda, Audi and SEAT might be affected. [6]
