L'effetto dieseling (o semplicemente diese … L'effetto dieseling (o semplicemente dieseling) o spegnimento ritardato avviene quando un motore a combustione interna continua a funzionare per un breve periodo dopo lo spegnimento, a causa dell'accensione spontanea del carburante. Questo fenomeno non è da confondere con l'autoalimentazione, che ha caratteristiche simili, ma cambia negli effetti. Il dieseling è così chiamato perché il carburante si accende spontaneamente, come nei motori Diesel, senza che la candela scocchi una scintilla. Tuttavia, l'accensione non è causata dalla compressione del carburante nel cilindro come nei Diesel, bensì dall'alta temperatura del cilindro stesso o di una parte della camera di combustione. di una parte della camera di combustione.
, Dieseling or engine run-on is a condition … 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 in effect to how diesel engines operate: by firing without a spark. The ignition source of a diesel engine is the heat generated by the compression of the air in the cylinder, rather than a spark as in gasoline engines. The dieseling phenomenon occurs not just because the compression ratio is sufficient to cause auto-ignition of the fuel, but also because a hot spot inside the cylinder (spark plug electrode, combustion-chamber/valve edge or even excess carbon) starts combustion. An automobile engine that is dieseling will typically sputter, then gradually stop. This is normally seen in carbureted engines with many miles on them. Dieseling is not nearly as common as it once was, because it most commonly occurs in engines equipped with carburetors. The vast majority of vehicles manufactured after 1987 are fuel-injected: the injectors and high-pressure fuel pump immediately cease supplying fuel to the cylinders when the ignition is switched off. If the injector is damaged or dirty, a small amount of fuel can enter the chamber and be ignited, causing a sputter or two after the engine is switched off. Until the mass-market introduction of fuel injection, the industry's remedy for dieseling was to install an electric solenoid into the fuel supply circuit of the carburetor, energized by the ignition coil primary wire: when activated, the solenoid would open and allow fuel to flow normally out of the float bowl, through the fuel-metering jets and into the engine; when deactivated, the solenoid would close and prevent fuel from being drawn through the jets and into the engine. This provided a simple, adequate solution to the dieseling problem. Dieseling (in the sense of engine run-on, and disregarding combustible gaseous mixtures via the air intake) can also occur in diesel engines, when the piston or seals fail due to overheating, admitting engine oil into the cylinder. A structurally failing diesel engine will often accelerate when the throttle is released, even after fuel injection is switched off. Some carbureted engines have low-pressure fuel pumps: they are typically designed only to overcome a loss of suction in the fuel line near the engine due to fuel evaporation in hot weather, to supply sufficient fuel to maintain stoichiometric combustion under heavy load with wide-open throttle, or a combination of the two. Fuel demand is low at idle and there is more than enough manifold vacuum to draw sufficient fuel for combustion, even if the fuel pump is switched off. Gasoline engines that are much smaller than the typical automotive engine are usually carbureted for economic and engineering reasons. Dieseling can occur in such engines. These engines include those installed in small generators, mopeds, scooters, small motorcycles, all-terrain vehicles, and most lawn and garden power tools.les, and most lawn and garden power tools.
