Flooding can also occur if the choke has been over applied or has malfunctioned. A severe form of engine flooding occurs when excessive liquid fuel enters the combustion chamber. This reduces the dead volume of the combustion chamber and thus places a heavy load on the starter motor, such that it fails to turn the engine. Damage (due to ...
Engine coolant entering the cylinders through various means (such as a blown head gasket) is another common cause. Excessive fuel entering ( flooding ) one or more cylinders in liquid form due to abnormal operating conditions can also cause hydrolock.
The reduced engine speeds allow more time for autoignition chemistry to complete thus promoting the possibility of pre-ignition and so called "mega-knock". Under these circumstances, there is still significant debate as to the sources of the pre-ignition event. [3] Pre-ignition and engine knock both sharply increase combustion chamber temperatures.
Flooding can strike in seconds or days in various forms, each with its own life-threatening potential. However, all types of flooding should be taken seriously. ... This causes water levels to ...
Honda said Wednesday it is recalling about 295,000 vehicles in the U.S. due to a software issue that could cause the engine to lose drive power.
Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
A record-breaking storm caused "extreme flooding" as waters entered buildings and swept away cars in Roswell, New Mexico.
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 ...
