The Hyundai Beta engines are 1.6 L to 2.0 L I4 built in Ulsan, South Korea.. All Beta engines are dual overhead camshaft valvetrain design.The Beta engine uses a direct-acting overhead cam valvetrain arrangement which places the camshaft in the cylinder head above the pistons and combustion chamber and operates the valve tappets/lifters directly.
Roto's disadvantage was the 2-3 range or 1-2 gear change because it is not only a huge ratio jump from 2-3 range or 1-2 shift from 2.93 to 1.56, but also there is no fluid slippage in the coupling because the coupling drains (four-tenths of a second) to engage or apply the front clutch and so the trans goes to full mechanical connection.
The Nu 2.0 L (1,999 cc) version of this engine features the same 81 mm (3.19 in) bore but with a longer stroke of 97 mm (3.8 in). First revision of the G4NA engine makes 166 PS (122 kW; 164 hp) at 6,500 rpm and 20.5 kg⋅m (148 lb⋅ft; 201 N⋅m) at 4,800 rpm while later revisions produce 152–156 PS (112–115 kW; 150–154 hp) at 6,200 rpm and 19.6–19.9 kg⋅m (142–144 lb⋅ft; 192 ...
The 2.4L version is an inline 4-cylinder engine that carries a bore of 88.0 mm, stroke of 97.0 mm and a 10.5:1 compression ratio; the engine dry weight is 146 kg (322 lb) and it makes 165 PS (121 kW; 163 hp) at 5,800 rpm and 22.3–23 kg⋅m (161–166 lb⋅ft; 219–226 N⋅m) of torque at 4,250 rpm.

Firefly previously pursued a medium-lift launch vehicle design known as Firefly Beta, which consisted of three Alpha cores strapped together. [48] In October 2019, Firefly announced a partnership with Aerojet Rocketdyne to develop a single core rocket potentially powered by the Aerojet Rocketdyne AR1 engine. [ 49 ]
The torque tube consists of a large diameter stationary housing between the transmission and rear end that fully encloses a rotating tubular steel or small-diameter solid drive shaft (known colloquially in the U.S. as a "rope drive" [1]) that transmits the power of the engine to a regular or limited-slip differential. [2]
The following stresses are induced in the shafts. Shear stresses due to the transmission of torque (due to torsional load). Bending stresses (tensile or compressive) due to the forces acting upon the machine elements like gears and pulleys as well as the self weight of the shaft. Stresses due to combined torsional and bending loads.
