1919 Napier Lion II aircraft engine with three cylinder banks. Any design of motor/engine,be it a V or a boxer can be called an "in-line" if it's mounted in-line with the frame/chassis and in-line with the direction of travel of the vehicle.When the motor/engine is across the frame/chassis this is called a TRANSVERSE motor.Cylinder arrangement is not in the description of how the motor/engine ...
A simple three-into-one exhaust for each cylinder bank provides uniform scavenging, since the engine is effectively behaving like two separate straight-three engines in this regard. Primary reciprocating plane and rotating plane imbalances are present due to the distance along the crankshaft between opposing cylinders.
The VR6 is a highly compact engine, thanks to the narrower angle of 10.5 to 15 degrees between cylinder banks, as opposed to the traditional V6 angles ranging from 45 to 90 degrees. The compact design is cheaper to manufacture, since only one cylinder head is required for all six cylinders, much like a traditional inline-6 engine.
The Chrysler Slant-Six is the popular name for an overhead valve inline-6 engine produced by Chrysler Motors between 1959 and 2000. Featuring a reverse-flow cylinder head and cylinder bank inclined at a 30-degree angle from vertical, it was introduced in 170 cu in (2.8 L) and 225 cu in (3.7 L) displacements for the 1960 model year.
A straight engine is easier to build than an equivalent flat engine or V engine, as it uses one cylinder head rather than two. Inline engines are also narrower than flat engines or V engines; however, they are longer and can be taller. The engine balance characteristics of a straight engine depend on the number of cylinders and the firing interval.
The Hemi-6 valves are angled apart (splayed) 18 degrees (included angle) along the crankshaft axis, and the intake valves are as large as 1.96 in (50 mm). The 6 intake and 6 exhaust valves open slightly towards each other and away from the cylinder wall, which results in less "shrouding" of the valves and greater airflow potential.
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The majority of automotive four-cylinder engines use a straight-four layout [ 1 ] : pp. 13–16 (with the exceptions of the flat-four engines produced by Subaru and Porsche) [ 2 ...
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 ...
