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]
Ignition timing. Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of ...
The three-component theory of stratification, more widely known as Weberian stratification or the three class system, was developed by German sociologist Max Weber with class, status and party as distinct ideal types. Weber developed a multidimensional approach to social stratification that reflects the interplay among wealth, prestige and power.
Pre-ignition (or preignition) in a spark-ignition engine is a technically different phenomenon from engine knocking, and describes the event wherein the air/fuel mixture in the cylinder ignites before the spark plug fires. Pre-ignition is initiated by an ignition source other than the spark, such as hot spots in the combustion chamber, a spark ...
Dieseling. 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. Dieseling is so named because it is similar ...

Loss on ignition (LOI) is a test used in inorganic analytical chemistry and soil science, particularly in the analysis of minerals and the chemical makeup of soil. It consists of strongly heating ( "igniting" ) a sample of the material at a specified temperature, allowing volatile substances to escape, until its mass ceases to change.
