It is called a straight engine (or 'inline engine') when the cylinders are arranged in a single line. Where the cylinders are arranged in two or more lines (such as in V engines or flat engines), each line of cylinders is referred to as a 'cylinder bank'. The angle between cylinder banks is called the 'bank angle'.
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.
Large two-stroke ship diesels are sometimes made to be reversible. Like four-stroke ship engines (some of which are also reversible), they use mechanically operated valves, so require additional camshaft mechanisms. These engines use crossheads to eliminate sidethrust on the piston and isolate the under-piston space from the crankcase.
Other split-single models from TWN were the 1954-1957 TWN Cornet (200 cc with 12 volt electrics and optionally electric starter), the 1953-1957 TWN Boss (350 cc) with 2 carburetors and the 1954-1957 Contessa scooter (200 cc). [1] The bulbous shape of the exhaust of the Cornet and Boss is an anti-noise two-stroke TWN feature.
The engine, known as the e-REX creates 4 times more power events per revolution than a conventional 4 Stroke and twice more than a 2 Stroke. [1] Although the e-REX is called a one-stroke engine there is debate that says it is actually a two-stroke engine, it is called a one-stroke because each piston executes two strokes (i.e., compression ...
In crankcase scavenged 2-stroke engines, exhaust and intake are performed mostly simultaneously and with the combustion chamber at its maximum volume. The main advantage of 2-stroke engines of this type is mechanical simplicity and a higher power-to-weight ratio than their 4-stroke counterparts. Despite having twice as many power strokes per ...
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 ...
Cutaway side-view diagram of an axial piston pump 3-D rendering of an axial piston pump with the parts labeled Animation of an axial piston pump in operation. An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel.
