Embodiment Construction

[0073] figure 1 A schematic diagram of an internal combustion engine 1 is shown. The internal combustion engine 1 is connected to two turbochargers 2 and 2' arranged in series. Each turbocharger comprises a compressor 20, 20' and a turbine 21, 21'. A separate air cooler 16, 16' is assigned to each turbocharger 2, 2'. The compressor 20, 20' of each turbocharger 2, 2' may be bypassed using a compressor bypass valve 14, 14'. Furthermore, each turbine can be bypassed using a turbine bypass valve 15, 15'. Thus, one of the turbochargers 2 , 2 ′, for example the second turbocharger 2 ′, can be bypassed and the internal combustion engine 1 can be operated using only the first turbocharger 2 . This may be useful if one of the turbochargers fails. The bypass valves 14, 15, 14', 15' can also be partially opened or closed depending on the desired mode of operation.

Abstract

An internal combustion engine (1) and corresponding method, cylinder, closing plate, cylinder and kit of parts, in particular a two-stroke engine, preferably a diesel two stroke engine, which comprises at least one piston (10) arranged in a cylinder (11). Said piston (10) and said cylinder (11) define a variable combustion chamber (101) and a variable second chamber (102). The variable combustion chamber (101) is fluidly connectable to the compressor side of a turbocharger (2,2') via at least one inlet opening (111) and to the turbine side of the turbo charger (2,2') via an exhaust opening (112). The second chamber (102) is fluidly connectable to the compressor side of the turbocharger (2,2') to introduce a compressed air flow into the second chamber (102). The compressed air flow is interruptible such that the second chamber (102) is disconnected from the turbocharger (2, 2') and the second chamber (102) comprises an outlet opening (113) for reducing a pressure of the second chamber (102). The outlet opening (113) preferably comprises a controllable chamber valve.

Description

technical field [0001] The present application relates to an internal combustion engine and a method of operating an internal combustion engine. The present application further relates to cylinders, cylinder liners and chamber seals. Background technique [0002] Various attempts have been made to increase the efficiency of internal combustion engines. The larger the internal combustion engine, the greater the effect of increased efficiency on fuel combustion. In particular, an increase in efficiency is advantageous in large internal combustion engines, such as two-stroke diesel engines of ships. [0003] For example, CH414265 proposes adding a generator to a two-stage turbocharger to utilize the energy generated by the supercharger. Such systems are complex. Retrofitting an existing engine requires many components. Furthermore, the generator requires additional components to adjust its voltage, current and frequency to eg existing grids. [0004] JPH0797926 discloses ...
