Good afternoon, Gentlemen!

My full name is Semetov Maxim. I am student of marine institute.

The topic of my presentation: Development of technical solutions for the maintenance and repair of the MAN 9L27 / 38 diesel engine.

The report is relevant for future engineers, as it covers an overview of M. D. E.

My talk will be in three parts:

In the first part, I will tell you about - M. D. E. parameters

Then in the second part, I'd like to describe - Main features

Finally, I’ll go on to talk about-Benefits at a glance

My presentation will take about 5 minutes

1/Have a look at Brief technical characteristics of the MAN 9L27 / 38 diesel.

The solid and reliable MAN L27/38 delivers good performance over the

entire load range with quick acceleration and immediate load response.

Its proven reliability ensures long time between overhauls (TBO) and no unscheduled maintenance or repair work.

Diesel type Four-stroke, trunk, non-reversible, supercharged

Number of cylinders 9

Cylinder diameter, mm 280

Piston stroke, mm 380

Maximum continuous power, kW (hp) 2850

Rotation frequency, rpm 750

Specific fuel consumption, g / kWh 185

We’ve looked at Brief technical characteristics of the MAN 9L27 / 38 diesel.
