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]
Low-speed pre-ignition (LSPI), also known as stochastic pre-ignition (SPI), [1] is a pre-ignition event that occurs in gasoline vehicle engines when there is a premature ignition of the main fuel charge. [2] LSPI is most common in certain turbocharged direct-injection vehicles operating in low-speed and high-load driving conditions. [3]

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 ...
Port injection refers to the spraying of the fuel onto the back of the intake valve, which speeds its evaporation. [1] An indirect injection diesel engine delivers fuel into a chamber off the combustion chamber, either a prechamber or swirl chamber, where combustion begins and then spreads into the main combustion chamber. The prechamber is ...
The naturally aspirated XUD11 A was bored to 86 mm (3.39 in) for a total displacement of 2.1 L (2,138 cc), while the turbocharged ATE/BTE versions were reduced in bore to 85 mm (3.35 in) for a total of 2.1 L (2,088 cc). The BTE engines used a Lucas EPIC (Electronically Programmed Injection Control) fuel pump, whereas the ATE engines used a ...
