DIESELING Meaning and
Definition
-
Dieseling refers to a phenomenon that occurs in internal combustion engines, particularly in automotive engines. It is the process where an engine continues to run or sputter even after the ignition has been turned off. Dieseling is also commonly known as "run-on," "after-running," or "engine run-on."
Dieseling is caused by the auto-ignition of the air-fuel mixture within the engine's cylinders, without the need for an ignition spark. This auto-ignition is triggered by the hot spots or glowing deposits inside the combustion chamber, such as the spark plug electrodes, carbon build-up, or glowing particles. When the engine is shut off, these hot spots continue to heat the air-fuel mixture which can result in erratic or sustained combustion, causing the engine to keep running or sputter in an irregular manner.
There are several factors that contribute to dieseling, including high compression ratios, elevated engine temperatures, incorrect ignition timing, excessive carbon build-up, and low octane fuel. Dieseling can lead to issues such as increased fuel consumption, overheating, damage to engine components, and potential safety hazards.
To prevent dieseling, various measures can be taken. This includes regular engine maintenance, such as cleaning the combustion chambers and spark plugs, adjusting ignition timing, maintaining proper fuel octane levels, and ensuring the engine is not running excessively hot. Additionally, shutting off the engine more smoothly by gradually reducing the throttle can help minimize the occurrence of dieseling.

Etymology of DIESELING
The term "dieseling" comes from the word "diesel", which refers to the type of internal combustion engine developed by German engineer Rudolf Diesel in the late 19th century. The etymology of "diesel" itself can be traced back to its inventor's surname, as Rudolf Diesel. The word "diesel" was eventually used to describe the fuel, the engine, and their characteristics. "Dieseling" emerged as a term to describe the occurrence of an engine continuing to run or ignite even after the ignition is turned off, similar to how a diesel engine can continue to operate due to compression ignition. Therefore, "dieseling" refers to this phenomenon wherein an internal combustion engine runs on despite the lack of ignition spark.
