In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front.
A flooded engine is an internal combustion engine that has been fed an excessively rich air-fuel mixture that cannot be ignited. [1] This is caused by the mixture exceeding the upper explosive limit for the particular fuel. An engine in this condition will not start until the excessively rich mixture has been cleared. [2]
For water-cooled engines on aircraft and surface vehicles, waste heat is transferred from a closed loop of water pumped through the engine to the surrounding atmosphere by a radiator. Water has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and ...

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.
Backfires and loud explosion-like sounds are common when an antilag system is present and active. Improper wiring in the ignition can also lead to timing issues and backfires. Low fuel pressure, clogged fuel filters , and weak fuel pumps could cause a severely lean air-to-fuel ratio during the fuel injection process.

A steam engine is a device which transforms heat into mechanical motion. This is provided with the usage of boilers, which create steam by boiling water. In the early 1900s, Abner Doble introduced a steam-powered car in the United States which had capabilities that could potentially overpower Ford's Model T in efficiency. [8]
