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.
For this inline-4 engine, 1-3-4-2 could be a valid firing order.. The firing order of an internal combustion engine is the sequence of ignition for the cylinders.. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated.
The 153 cu in engine had a 3 + 7 ⁄ 8-inch (98 mm) bore and 3 + 1 ⁄ 4-inch (82.6 mm) stroke, with two overhead valves per cylinder actuated by pushrods and a 1-3-4-2 firing order. The Chevy II 's 194 cu in six-cylinder used a 3 + 9 ⁄ 16 -inch (90.5 mm) bore, which by 1964 was enlarged to match the 153 four-cylinder's resulting in a ...
The light generally [3] has two stages: steady (indicating a minor repairable fault, but service on the vehicle is strongly recommended as soon as possible to prevent future damage) and flashing (indicating a severe fault and an emergency that makes the vehicle unsafe to drive and it is strongly recommended that the vehicle gets mechanical ...
With an inclined or horizontal type, the cylinder and piston are positioned at an incline or horizontally. An inclined inverted cylinder is a cylinder operating at a downward incline. These terms are all generally used in conjunction with the engine types above. Thus, one may have a horizontal trunk engine, or an inclined compound engine, etc.
A cylinder from an air-cooled aviation engine, a Continental C85. Notice the rows of fins on both the steel cylinder barrel and the aluminum cylinder head. The fins provide additional surface area for air to pass over the cylinder and absorb heat. Flat-four aircraft engine
Three-cylinder fans were known as W or W-3 engines. The appeal of the fan configuration was that, because all the cylinder were above the horizontal there was little danger of the plugs being fouled by the lubricating oil. The disadvantage, particularly for an aircraft engine, was the extra weight required to counterbalance the pistons.
Liquid seal flame arrestors are liquid barriers following the principle of a siphon where the liquid stops the entering deflagration and/or detonation and extinguishes the flame, they work by bubbling the gas through a non-flammable and ideally non-gas-absorbing liquid, which is typically water.
