The crankshaft configuration varies amongst opposed-engine designs. One layout has a flat/boxer engine at its center and adds an additional opposed-piston to each end so there are two pistons per cylinder on each side. An X engine is essentially two V engines joined by a common crankshaft. A majority of these were existing V-12 engines ...
Crankshaft (red), pistons (gray), cylinders (blue) and flywheel (black) A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, [1] that are driven by the pistons via the connecting rods. [2]
In engines with only a single cylinder the flywheel is essential to carry energy over from the power stroke into a subsequent compression stroke. Flywheels are present in most reciprocating engines to smooth out the power delivery over each rotation of the crank and in most automotive engines also mount a gear ring for a starter.
2002 and earlier engines featured a one-piece cast nodular iron crankshaft with counterweights present on either side of each crank pin. A crankshaft tone wheel was present between number 1 and number 2 connecting rod pins, and was machined such that a Hall-effect magnetic pickup mounted to the engine block could read the crankshaft's position ...
The larger displacement engine included a pioneering electronic fuel-injected (EFI) system named "Electrojector" version in 1957. All these engines share common external dimensions, lightweight - about 600 lb (270 kg) - forged crankshaft and rods, as well as most other parts. [7] The stroke for all Gen-1 V8s is 3 + 1 ⁄ 4-inch (82.6 mm).
All G engines used forged steel crankshafts until the middle of model year 1976, when a less costly cast-iron crankshaft was introduced. The cast crankshaft uses a different block, different main and connecting rod bearings and different connecting rods. The counterbore in the rear flange of the crankshaft was 1 + 1 ⁄ 4 inches (32 mm ...
