Stroke ratio, today universally defined as bore/stroke ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length in...

Atkinson, its expansion ratio can differ from its compression ratio and, with a power stroke longer than its compression stroke, the engine can achieve...

way is the static compression ratio: the ratio of the volume of the cylinder when the piston is at the bottom of its stroke to that volume when the piston...

six-stroke engine is one of several alternative internal combustion engine designs that attempt to improve on traditional two-stroke and four-stroke engines...

97.3 cu in (1,595 cc) Compression ratio: 10.8:1 Bore x stroke: 81 mm × 77.4 mm (3.19 in × 3.05 in) Rod/Stroke ratio: 1.85:1 Rod Length: 142.42 mm (5.607 in)...

Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines...

three engine (R3/I3); bore × stroke: 76.5 mm × 86.9 mm (3.01 in × 3.42 in), stroke ratio: 0.88:1 – under-square/long-stroke, 399.4 cc per cylinder cylinder...

three engine (R3/I3); bore x stroke: 74.5 mm × 76.4 mm (2.93 in × 3.01 in), bore spacing: 82 mm (3.2 in), stroke ratio: 0.99:1 – 'square engine', 333...

EA189 engine family. EA288 diesel shares displacement, bore pitch, stroke and bore ratio with the EA189 and the new EA211 gasoline engines. It is a family...

bore x stroke: 81.0 mm × 86.4 mm (3.19 in × 3.40 in), stroke ratio: 0.94:1 – undersquare/long-stroke, 445.2 cc per cylinder; compression ratio: 10.6:1...
