Turbocharger is one of the most important parts of engines, the main propulsion system of the ship. We would like to explain its role and mechanism.
A turbocharger is a device that sends compressed air to the engine.
The turbine converts the energy of the exhaust gas discharged from the engine into rotational energy, transmits the torque to the coaxial compressor, and the compressor rotates at high speed to forcibly suck the air into the cylinder of the engine.
By installing a turbocharger,
-Since more air can be sent into the engine cylinder, higher output can be achieved for the same size engine.
-In other words, it is possible to reduce the weight and volume of the engine compared with the same engine output.
-It contributes to the reduction of fuel consumption by improving the engine efficiency in the engine, and the exhaust gas reduction effect can be obtained by combining with various tunings on the engine side.
The basic layout of a turbocharger consists of a compressor, a turbine and a shaft that connects them, but various layouts are available depending on their position, the direction of inflow of air or gas and the mounting position of the bearing that holds the bearing.
Currently, from the viewpoint of compactness, high efficiency and high reliability, a turbocharger is an intermediate support type in which a bearing is interposed between the compressor and turbine. There are two main types.
