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.
When configuring, testing, and running any overspeed systems on turbines or diesel engines, one factor considered is timing. [4] This is because the response to overspeed is usually too fast for people to notice. There is a strong argument to instrument the trip systems in such a way that the total system response can be measured.
Simultaneous problems with GM's new THM200 automatic transmission made the overall problem worse. The California Air Resources Board (CARB) had been unable to certify the diesel V8 for sale in the state in 1979 and early 1980 as the test cars issued to CARB broke down before the tests could be completed. Of the nine cars supplied to CARB, all ...
The Standard lists 12 climatic regions and the limits range from −3 °C to 15 °C. Ordinarily, Australian automotive diesel fuels on average have a cold filter plugging point value that is about 2 °C below the cloud point. The Standard also lists particular locations where fuel problems may possibly occur because of cold weather conditions. [10]
The Navistar DT (Diesel Turbocharged or Diesel Turbo) engine family is a line of mid-range inline-6 diesel engines.With horsepower ratings ranging from 170 hp (130 kW) to 350 hp (260 kW), the Navistar DT engines are used primarily in medium-duty truck and bus applications such as school buses, although some versions have been developed for heavy-duty regional-haul and severe-service applications.

Animation of the Atkinson differential engine 1932 Junkers Jumo 205 diesel aircraft engine. One of the first opposed-piston engines was the 1882 Atkinson differential engine, [7] which has a power stroke on every rotation of the crankshaft (compared with every second rotation for the contemporary Otto cycle engine), but it was not a commercial success.
