In another arrangement, one rotor is inside the stator with a second rotor on the outside of the stator. [2] The photo labelled FIG. 8 is from a patent application. It shows two rotors assembled into a single unit, with eight permanent magnets attached to the outer surface of the inner rotor, and eight to the inner surface of the outer rotor. [5]
The M4+2 engine, also known as the double-piston internal combustion engine, is a type of internal combustion engine invented by Polish patent holder Piotr Mężyk. [1] The M4+2 engine took its name from a combination of two-stroke engines and four-stroke engines. The two-stroke combustion engine is characterized by a simple construction and ...
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 ...
The combustion cycle can be either two-stroke (which results in a lighter engine for a given power output) [3] [4] or four-stroke (which produce lower levels of exhaust gas emissions). [5] [6] The fuel is usually either petrol or diesel. [7] In 1973, a small Wankel (rotary) engine manufactured by NSU was used in a lawn mower. [8]
The uniflow method of scavenging has been often used for two-stroke diesel engines in motor vehicles, marine vessels, railway locomotives and as stationary engines. Its drawback is the additional complexity, mass, volume, and cost required to implement the poppet valvetrain (or the additional crankshaft or rocker arms required to control a ...
An insurance broker is an intermediary who sells, solicits, or negotiates insurance on behalf of a client for compensation. An insurance broker is distinct from an insurance agent in that a broker typically acts on behalf of a client by negotiating with multiple insurers, while an agent represents one or more specific insurers under a contract.
In fact there was at least one valve in Joseph Day's original design, a simple check valve in the inlet port communicating directly with the crankcase, where you would probably find a reed valve on a modern two stroke. His patent No.6,410 of 1891/2 covered variants with a piston controlled transfer port or an additional check valve in the crown ...
Typical horizontal steam engine with double-acting cylinder. A double-acting cylinder is a cylinder in which the working fluid acts alternately on both sides of the piston. . In order to connect the piston in a double-acting cylinder to an external mechanism, such as a crank shaft, a hole must be provided in one end of the cylinder for the piston rod, and this is fitted with a gland or ...
