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.

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]

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.
Most diesel engines do not have a throttle body, so regardless of the throttle setting, air is always drawn into the cylinders (excluding the valve fitted to certain diesels, such as fire appliances and generators on oil and gas platforms, to prevent diesel engine runaway). The fuel-free air mix that is compressed on the compression stroke now ...

In 2023, Cummins unveiled the X10 and X15N engines. The X10 is slated to replace the X12 and L9 in the truck market as it was made to serve both heavy duty and medium duty truck applications. [1] The X15N is a CNG version of the X15, and is expected to release in 2025 with the same performance as the X15. [2]
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]
