The Ford 5.4L Modular Engine features a bore and stroke of 90.1 mm × 105.8 mm (3.55 in × 4.17 in), which makes a bore/stroke ratio of 0.852:1. Since the stroke is significantly longer than the bore, the SOHC 16V (2-valve per cylinder) version of this engine is able to generate a peak torque of 350 lb·ft as low as 2501 rpm.
The prior EJ20 used an oversquare 92 mm × 75 mm (3.62 in × 2.95 in) bore and stroke for a 1,994 cc (2.0 L) swept displacement; in comparison, the FB20 features an undersquare bore and stroke for a slightly larger displacement. All FB20 variants: Displacement: 1,995 cc (2.0 L) DOHC; Bore x stroke: 84 mm × 90 mm (3.31 in × 3.54 in)
Pedal pushers are known now in society as a popular 2000s or Y2K look. As of January 2024, a new trend seen in places like New York and Copenhagen, pedal pushers or "Capris" were making a return. [citation needed] The 2023 runways were exhibiting pedal pusher styles. Several designers took the step and created modern and new ways to style the ...
The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds or torque at lower engine speeds. [ 2 ] [ 3 ] The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons .
Compression ratio: 17.5:1 The 5.9 L Cummins, also known as the "12-Valve" Cummins was the first member of the Cummins B-Series to be used in a light truck vehicle. The 6BT used Bosch fuel systems, injector, and VE rotary pump and P7100 inline injection pumps.
The fuel-air mixture in the crankcase is then forced past the piston via the transfer/bypass ports in the cylinder. One characteristic of a reed valve is that the engine will run in either direction; an advantage for a "pusher" model but a disadvantage if the engine is finger started, as it may start in the wrong direction.
It is the ratio between the volume of the cylinder, when the piston is at the bottom of its stroke, and the volume when the piston is at the top of its stroke. The bore/stroke ratio is the ratio of the diameter of the piston, or "bore", to the length of travel within the cylinder, or "stroke". If this is around 1 the engine is said to be "square".
The Rotax 912 was first sold in 1989 in non-certificated form for use in ultralights and motorgliders. [3]The original 60 kW (80 hp) 912 UL engine has a capacity of 1,211 cc (73.9 cu in) and a compression ratio of 9.1:1, and is designed to work with regular automotive gasoline, with up to 10% ethanol.
