Abstract

An exhaust module (1) for a turbocharged (17) reciprocating engine (13), in which the cylinders (14) are arranged in two banks (15, 16). The exhaust module (1) comprises a first exhaust manifold (2) for receiving exhaust gas from cylinders of a first cylinder bank (15), said first exhaust manifold (2) having a first end (4) and a second end (5), and a second exhaust manifold (3) for receiving exhaust gas from cylinders of a second cylinder bank (16), said second exhaust manifold (3) having a fist end (6) and a second end (7). The exhaust module (1) is provided with a connecting duct (9) that connects the second end (5) of the first exhaust manifold (2) to the first end (6) of the second exhaust manifold (3). The exhaust module is also provided with a second connecting duct (8) for connecting the second end (7) of the second exhaust manifold with a turbine inlet (20).

Description

technical field [0001] The invention relates to an exhaust module of a reciprocating engine in which the cylinders are arranged in a V-shaped configuration. The invention also relates to reciprocating engines. Background technique [0002] In large reciprocating engines, such as those used in ships or power plants, the exhaust manifold is large and therefore difficult to install on the engine. In a V-engine where exhaust gases from both cylinder banks are directed to the same turbocharger, the exhaust flow from the cylinder banks is usually combined by a Y-piece preceding the turbocharger. This changes the flow rate of the exhaust gases and the flow conditions when the gas streams combine, which can cause operational problems for the turbocharger. In addition, the Y-piece warps due to thermal expansion. Contents of the invention [0003] The object of the present invention is to provide an improved exhaust module for a turbocharged reciprocating engine in which the cyli...
