2 слайд

A slow speed or medium speed Diesel engine is a high pressure propulsion plant with internal combustion.

3 слайд

s In a V-engine the cylinders are placed in an oblique (or bevel) position, unlike the in-line engine, where the cylinders are placed “in line”. V-engine In-line engine

6 слайд

The cylinder is filled with air. S During the compression stroke the air in the cylinder is compressed. cylinder

7 слайд

The atomizer (1) sprays the fuel into the cylinder. The nozzle divides the fuel into small particles. 1 atomizer Tip of the atomizer (nozzle).

8 слайд

During the power stroke the fuel is injected and burnt. This actuates the piston (1) and connecting rod (2). 1 2

9 слайд

The piston makes a reciprocating motion. Piston

10 слайд

1 2 3 The crosshead (1) serves as a hinging connection between piston rod (2) and connecting rod (3). Crosshead guides and crosshead guide shoes (4) absorb the forces onto the crosshead when the piston goes down. 4

11 слайд

S The crank (1) is connected to the crankshaft (2). 1 2

12 слайд

S The crank changes the reciprocating motion of the piston into a rotary motion of the crank shaft .

13 слайд

S Gearwheels to drive the camshaft are driven by chains (“chaindrive”). camshaft

14 слайд

S The campeak is fixed to the camshaft. campeak campeak

15 слайд

s The push rod (1) may be used as a distance piece between campeak (2) and rocker arm (3). 1 3 2

16 слайд

S The exhaust valve (1) is actuated (opened) by the rocking lever (2) (rocker arm). 2 1

17 слайд

S The exhaust valve is actuated (closed) by the exhaust valve spring (1). 1

18 слайд

S The scavenging air manifold (1) and scavenging ports (2) supply the scavenging air to remove the exhaust gases. 1 2

20 слайд

S The cylinder liner (1) and cylinder jacket (2) form the cylinder wall. 1 2 Cooling the cylinder:

21 слайд

A coolant (fresh water) is injected between liner and jacket to cool the cylinder. s Cooling the cylinder:

22 слайд

s Cooling the piston: The advantages of oil as a coolant are: . it reduces noise; . it purifies; . it forms a seal; . it lubricates; . it is anti-corrosive; . it has a higher resistance to heat. The piston is cooled by oil.

23 слайд

SO The piston rings (1) form a seal around the cylinder and carry away the heat. 1 Piston rings

24 слайд

s

25 слайд

S During the air induction stroke (or inlet stroke, or suction stroke) air is drawn into the cylinder.

26 слайд

S During the compression stroke the air in the cylinder is compressed.

27 слайд

S During the power stroke fuel is injected and burnt.

28 слайд

S During the exhaust stroke the exhaust gases are driven out of the cylinder by the piston.
