The efficiency of the two-stroke engine depends on effective scavenging, the more complete replacement of the old spent charge with a fresh charge. Apart from large diesels with separate superchargers, two-stroke engines are generally piston-ported and use their crankcase beneath the piston for compression. The cylinder has a transfer port ...
A cutaway, in the industrial sense, refers to the display of a manufactured product, (an engine, a pump, a regulator, etc. . .) where a portion of the exterior housing has been removed to reveal the internal components, (pistons, bearings, seals, etc. . .) and their relationship to the functionality of the product.
Cutaway view of the fuel system for the Ford Model T engine, showing the gravity-feed fuel supply, carburetor cutaway, and intake stream. [4] The Ford Model T engine had one carburetor, a side-draft, single-venturi unit. Its choke and throttle valves were controlled manually; the latter was with a hand lever rather than a foot pedal. The ...
Cutaway model of a MAN B&W two-stroke marine diesel engine with the piston rod attached to a crosshead. In the two-stroke cycle, the four stages of internal combustion engine operation (intake, compression, ignition, exhaust) occur in one 360° revolution of the crank shaft, whereas in a four-stroke engine they take two complete revolutions.
For two-stroke engines, crossflow scavenging was used in early crankcase-compression engines, such as used by small motorcycles. The transfer port (where the fuel/air mixture enters the combustion chamber) and the exhaust port were located on opposite sides of the combustion chamber. This arrangement had the advantage of simplicity, but it also ...
The M4+2 engine has a four-stroke piston and a two-stroke piston. The shaft of the four-stroke piston rotates twice as fast as the shaft of the two-stroke piston, and the two-stroke part always runs at half speed. This ensures that both parts work optimally regarding fuel consumption at all times.
An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.
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 ...
