2017年12月20日 · In the early 1950s, MAN again offered their double-acting, two-stroke diesel engines. The largest of these post-war engines was the D8Z 70/120. With a 27.6 in (700 mm) bore and a 47.2 in (1,200 mm) stroke, the eight-cylinder engine displaced 430,953 cu in (7,062 L) and produced 8,000 hp (5,966 kW) at 120 rpm.

Single-acting cylinders are found in most kinds of reciprocating engine. They are almost universal in internal combustion engines (e.g. petrol and diesel engines) and are also used in many external combustion engines such as Stirling engines and some steam engines. They are also found in pumps and hydraulic rams.

A considerable number of double-acting diesel engines (Figure 1-6), namely the HOR and MAN engines, were used in installations for fleet type submarines until recent years. Lately, however, most of these double-acting engines have been removed …

Paul Henry Schweitzer argues that the opposed piston two-stroke diesel engine was originally invented by Hugo Junkers. [9] During World War I, MAN Nürnberg built a six-cylinder, double-acting piston, two-stroke diesel engine with a rated power of 12,400 PS (9,120 kW; 12,230 hp). [6]

In the 1930s H.O.R. developed a double-acting two-stroke diesel engine, initially based on the German cruiser Leipzig's MAN engines but with eight cylinders instead of seven, expanded to nine cylinders in the final submarine version. [9] The double-acting design produced more power from a physically smaller engine than conventional designs.

It was built in 1932 by Burmeister & Wain and was the largest Internal Combustion Engine in the World for about 30 Years. It is ...more. See what others said about this video while it was live....

2022年8月9日 · A marine diesel engine is a type of reciprocating internal combustion engine that runs on either diesel or dual fuel. It is bulkier and more complex than a petrol engine but offers higher operational efficiency. The diesel engine, named after Rudolf Diesel, creates power by adding fuel to high temperature compressed air. The resulting ...
