Marine Diesel Engine Turbocharger

#turbocharger #supercharger #marineengine
Marine Diesel Engine Turbocharger is an integral part of the ship’s marine engine as it reuses the exhaust gases in order to increase the overall efficiency of the engine. The equipment consists of a turbine and blower attached on the same shaft. The rotation of the turbine side as a result of the exhaust gases flowing over it turns the blower and supplies air to the scavenge side.
Turbocharger converts the waste energy of exhaust gas into useful work by supercharging the combustion process, and hence it is important to maintain the machinery.
As a marine engineer working on ships, you would be required to monitor the performance of turbochargers during the watch and carry out maintenance whenever required. This video explains the construction of a marine turbocharger, along with its operation and another important type which is Variable Geometry Turbocharger or VGT.

    Compression pressure totally depend upon compression ratio of the engine. The air flow will depend on the supply from the turbocharger, which in-turn will depend on the exhaust produced by the engine.

    Why vta turbocharger don’t have auxiliary blower ?

  • @marineinsight

    @marineinsight

    3 жыл бұрын

    Auxiliary blowers are needed when the engine starts, i.e. turbocharger speed is very low and they cannot supply fresh air during the initial period. However, with VTA, it can supply pressurised air at low speed by changing angle hence additional auxiliary blowers are not needed.

    Why aux blower is not required if vgt is there??? Even during starting we need scavenge air supply so blower must be there but on further load it’s use may not be required because of vgt. Please someone clarify my statement

  • @jagdish99_sw

    The use of auxiliary blower comes in to play when the engine is at low load or we can say during the starting of the engine the pressure gained in the cylinder at the starting of the engine is not enough to provide a efficient combustion bcoz the scavenge pressure is low.....so after a particular period of time suppose half an hour aftr the engine starts the scavenging pressure comes to a point where auxiliary blowers cuts off his role automatically...when the scavenging pressure is achieved to its mark. I hope u got it

    @@jagdish99_sw from what i understood from the video is that in VGT the nozzle angle in the T/C can be changed as needed. SO, whereas in normal T/C the fixed nozzles requires high load to rotate the turbine, during starting the load achieved is just not high enough hence aux blower is provided. BUT in the case of VGT the nozzle can be adjusted so as to provide high roatation energy in turbine with low load ( this is possible due to changing angle of nozzle ) . So the aux blower in the case of VGT is not required as low load can also produce rotation in T/C. I hope this helps. Someone correct me if I am wrong @marineinsight

    The compressor outlet is at high temperature which cannot be used directly for the scavenge space. Hence, it is first passed through air cooler to cool the air down to ~40°c
