The Wheeler–Schebler Carburetor Company was one of the Indianapolis's most important auto parts manufacturers and the last automobile parts factories in Indianapolis, Indiana to survive from the first decades of the 20th century. The Wheeler–Schebler Carburetor Company Building was the company's original building at the Barth Avenue site. [3]
In a four-stroke engine it is often desirable to provide extra fuel to the engine at high loads (to increase the power output and reduce engine knocking). A 'power valve', which is a spring-loaded valve in the carburetor that is held shut by engine vacuum, is often used to do so.
The Trojan two-stroke, as used from 1913 in the Trojan car in the UK, was independently invented but would now be described as a split-single. Photos of a 1927 "twin" model at the London Science Museum show the internals. [6] The "fore-and-aft" layout of the cylinders means that the V-shaped connecting rod has to flex slightly with each revolution.
Operating cycle for a four-stroke engine Operation of a flat-twin engine Operation of a straight-four engine. Although some components within the engine (such as the connecting rods) have complex motions, all motions can be separated into reciprocating and rotating components, which assists in the analysis of imbalances.
A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...
In four-stroke cycle engines and some two-stroke cycle engines, the valve timing is controlled by the camshaft. It can be varied by modifying the camshaft, or it can be varied during engine operation by variable valve timing. It is also affected by the adjustment of the valve mechanism, and particularly by the tappet clearance.
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.
A straight-twin engine, also known as an inline-twin, vertical-twin, inline-2, or parallel-twin, is a two-cylinder piston engine whose cylinders are arranged in a line along a common crankshaft. Straight-twin engines are primarily used in motorcycles; other uses include automobiles, marine vessels, snowmobiles, jet skis , all-terrain vehicles ...
