A desaxe engine, is one in which each cylinder is positioned with its exact center (the bore axis) slightly offset from the center line of the crankshaft. "Désaxé", in French, means "unbalanced". Desaxe engines are usually automotive, but the term can also apply to steam engines. An animation of a Scuderi Split Cycle Engine.
If the detonation is severe, the cylinder pressure can increase to eight times above normal pressures, [citation needed] which can cause the cylinder head to lift away from the engine block, disrupting the seal between the two. Most gaskets used in standard production engines can be critically damaged by severe detonation.
An engine is described as oversquare or short-stroke if its cylinders have a greater bore diameter than its stroke length, giving a bore/stroke ratio greater than 1:1. An oversquare engine allows for more and larger valves in the head of the cylinder, higher possible rpm by lowering maximum piston speed, and lower crank stress due to the lower ...
Unlike most acid-based rust removers, POR-15–short for Paint Over Rust–not only melts away rust, but preps the metal underneath for paint by lightly etching the metal and leaving behind a zinc ...
Once you've removed the rust, rinse the object with clean water to remove any remaining vinegar-and-salt residue and place it back into the container with fresh water. Add two tablespoons of ...
Bore × stroke are 3.501 by 3.625 inches (88.9 mm × 92.1 mm), and compression is 8.0:1. Overheating was a serious concern for the engine, since the engine block was of an open-deck design, severe overheating could cause the cylinder barrels to warp and pull away from the head gasket, causing coolant leaks into the cylinders and cylinder scuffing.
Testing is done on an engine which is not running, and normally with the tested cylinder at top dead center on compression, although testing can be done at other points in the compression and power stroke. Pressure is fed into a cylinder via the spark plug hole and the flow, which represents any leakage from the cylinder, is measured. Leak-down ...
An indicator diagram is a chart used to measure the thermal, or cylinder, performance of reciprocating steam and internal combustion engines and compressors. [1] An indicator chart records the pressure in the cylinder versus the volume swept by the piston, throughout the two or four strokes of the piston which constitute the engine, or ...
