A two-strokeengine is a type of internal combustion engine that completes a power cycle with two strokes of the piston in one revolution of the crankshaft. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust functions occurring at the same time.
A container ship is a cargo ship that carries all of its load in truck-size intermodal containers, in a technique called containerization. Container ships are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo.
The Jumo 205 aircraft engine was the most numerous of a series of aircraft diesel engines produced by Junkers. The Jumo 204 first entered service in 1932. Later engines of this type comprised the experimental Jumo 206 and Jumo 208, with the Jumo 207 produced in some quantity for the Junkers Ju 86P and -R high-altitude reconnaissance aircraft, and the 46-meter wingspan, six-engined Blohm & Voss BV 222 Wiking flying boat. All three of these variants differed in stroke and bore and supercharging arrangements. In all, more than 900 of these engines were produced, in the 1930s and through most of World War II.

Orient Overseas Container Line, commonly known as OOCL, is a container shipping and logistics service company with headquarters in Hong Kong. The company is incorporated in Hong Kong as Orient Overseas Container Line Limited and separately incorporated as Orient Overseas Container Line Inc. in Liberia. The latter was also re-domiciled to the Marshall Islands.
Emma Mærsk is the first container ship in the E class of eight owned by A.P. Møller – Mærsk A/S. When launched in 2006, she was the largest container ship ever built, and in 2010, she and her seven sister ships were among the longest container ships. Officially, she is able to carry around 11,000 twenty-foot equivalent units (TEU) or 14,770 TEU, depending on definition. In May 2010, her sister ship Ebba Mærsk set a record of 15,011 TEU in Tanger-Med, Tangier.
Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air/fuel mixture for the next cycle. If scavenging is incomplete, the remaining exhaust gases can cause improper combustion for the next cycle, leading to reduced power output.
A two-stroke diesel engine is a diesel engine that uses compression ignition in a two-stroke combustion cycle. It was invented by Hugo Güldner in 1899.

An internal combustion engine is a heat engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons, turbine blades, a rotor, or a nozzle. This force moves the component over a distance. This process transforms chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to.
CMA CGM Kerguelen is a 17,722 TEU very large UK flagged Explorer class container ship owned by the French shipping company CMA CGM. As of August 2015, it was the largest container ship in the fleet of CMA CGM. The ship is named for French-Breton naval officer and explorer Yves-Joseph de Kerguelen-Trémarec.
