Hugo Güldner designed what is believed to be the first operational two-stroke diesel engine in 1899, and he convinced MAN, Krupp and Diesel to fund building this engine with ℳ 10,000 each. [2] Güldner's engine had a 175 mm work cylinder, and a 185 mm scavenging cylinder; both had a stroke of 210 mm.
The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by the Finnish manufacturer Wärtsilä. It is designed for large container ships that run on heavy fuel oil . Its largest 14-cylinder version is 13.5 meters high, 26.59 meters long, weighs over 2,300 tonnes , and produces 80.08 megawatts .
Two-stroke diesels with high pressure forced induction, particularly turbocharging, make up a large percentage of the very largest diesel engines. In North America , diesel engines are primarily used in large trucks, where the low-stress, high-efficiency cycle leads to much longer engine life and lower operational costs.
In 2006 the MAN Diesel AG established a common European corporation named MAN Diesel SE (Societas Europaea). [2] On 22 February 2006 in Copenhagen the first diesel engine with more than 75,000 kW (101,000 hp) went into service. MAN B&W Diesel licensee Hyundai Heavy Industries in Korea built the 12K98MC with 75,790 kW (101,640 hp).
The Detroit Diesel 149 is a series of two-stroke diesel engines manufactured by Detroit Diesel which were first announced in early 1966. After Detroit Diesel was spun off in 1988 and later acquired by MTU, production of Series 149 engines was discontinued around 2000. [9] [10]
The inline six-cylinder 71 series engine was introduced as the initial flagship product of the Detroit Diesel Engine Division of General Motors in 1938.. This engine was in high demand during WWII, necessitating a dramatic increase in output: about 57,000 6-71s were used on American landing craft, including 19,000 on LCVPs, about 8,000 on LCM Mk 3, and about 9,000 in quads on LCIs; and 39,000 ...
Since then, the development of four-stroke engines has been carried out in Augsburg, while two-stroke engines are designed in Copenhagen. [11] The marketing name for the largest two-stroke engines still has "B&W" in it. [14] [15] In 1982, the first two-stroke large diesel engine with over 50% efficiency was built. [11]
The Detroit Diesel Series 110 is a two-stroke diesel engine series, available in straight-6 cylinder configuration (in keeping with the standard Detroit Diesel practice at the time, engines were referred to using a concatenation of the number of cylinders and the displacement, so this was a model 6-110).
