The Hyundai Gamma engine was introduced in 2006 to replace the existing Hyundai Alpha engine. [1] There are 1.4 L and 1.6 L versions of this engine. The Gamma II can apparently run in Atkinson cycle (leaving intake open longer for more complete burn but less displacement) under low loads for additional fuel economy with the ability to shift to Otto cycle on demand under high loads or for extra ...
The engine was developed for the Yak-42, An-72 and An-74 aircraft and was very advanced when it was first introduced in the 1970s. The engine was designed by Vladimir Lotarev . The first test runs began in 1971, first flight tests followed in 1974, serial production began in 1977.
As a large scale manufacturer, Mitsubishi had a wealth of experience building engines, both gasoline and diesel, in V and straight engine block configurations during the war. One of their many examples was the air-cooled A6120VDe air-cooled inline 6-cylinder 14.4 L diesel and the SA12200VD air-cooled V-12 diesel (21.7 litres).
In 1968, the engine displacement was increased again to 1298 cc with new bore and strokes of 78.5 mm x 67.1 mm and also renamed to R92B. Equipped with new two Mikuni-Solex 50PHH carburettors, the power also increased to 140 PS (103 kW) at 8000rpm with 127 N.m at 7000 rpm of torque.
The 2.5 L (2,497 cc) A II is produced since 2007. Cylinder bore and stroke is 91 mm × 96 mm (3.58 in × 3.78 in). Cylinder bore and stroke is 91 mm × 96 mm (3.58 in × 3.78 in). This series saw the introduction of a variable geometry turbocharger as an improvement from the initial traditional turbocharger of the A I while some later models ...
The displacement was decreased to 1.5 L (1498 cc) by decreasing the stroke size of HD engine to 82.6 mm but retained the same 76.0 mm bore size. [4] The compression ratio is 9.5:1. Maximum power is between 81–100 PS (80–99 hp; 60–74 kW) at 5600–6300 rpm with 112–127 N⋅m (11.4–13.0 kg⋅m; 83–94 lbf⋅ft) at 3200–3600 rpm of ...
Furness Railway No. 3 – "Old Coppernob" 0-4-0 tender engine of 1846, preserved at the National Railway Museum in York. Furness Railway No. 20 – Sharp Stewart Class A5 0-4-0 tender engine of 1863, now at Ribble Steam Railway in Lancashire .
The D-436 engine was developed as a follow on to the Lotarev D-36. The engine took several of its design features from that engine and another Progress engine, the Progress D-18. The D-436 incorporated an updated, higher RPM fan, a lower emissions combustor, and new compressor sections. Several variants of the engine incorporate a FADEC.
