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.

Does the compression air pressure remains same through out the all rpm range of an marine 2 stroke engine can you please explain how the air flow to the combustion chamber is controlled when rpm is increased or decrease

@marineinsight 4 жыл бұрын

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.

I have a question for you Bro.... I have twice EMD turbochargers 16-645 E7B & one Turbocharger 20-645 E3. One customer have several problems in his 3 EMD Engines 12 cilinders Turbocharged. Bro....based in your experiences, Can I supply and mount my Turbochargers on these Vessel? Could there be any inconveniences in the oil and fuel consumption of those engines? Thanks for your answer...Best Regards from Paraguay!!!!!!

You need to refer to the Bed Test of the engine. Also, makers are the best person to contact and ask if the turbocharger is a good match for the engine.

Why vta turbocharger don’t have auxiliary blower ?

@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 turbocharger inlet temperature is more than exhaust temperature?

@alphaq689 3 жыл бұрын

Some exhaust gas heat and pressure energy is transferred to mechanical rotating energy, thus pressure reduce along with temperature

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 3 жыл бұрын

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

@alphaq689 3 жыл бұрын

@@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

Why air cooler is used Marine diesel Engine ?

@marineinsight 4 жыл бұрын

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
