Marine diesel engine parts company introduces the structural type of diesel engine

According to the medium of the cooling cylinder, it can be divided into air-cooled diesel engines, water-cooled diesel engines and oil-cooled diesel engines.

Diesel engine structure type:

1, cylinder piston type and cross head type two diesel engines

The main features of the crosshead diesel engine are: there is no side thrust between the piston and the cylinder liner, and the side thrust is borne by the crosshead slider and guide plate, which improves the service life of the piston and cylinder liner; Reliable work, easy maintenance; Low vibration, low noise.

2, vertical and horizontal diesel engines

Cylinder center line perpendicular to the ground is called vertical diesel engine, cylinder center line parallel to the ground is called horizontal diesel engine,

3, large low-speed machines are single-row; Medium speed machine adopts single row type and V type two, a few use double row type; There are certain principles about the order of cylinder numbers in diesel engines.

(a) Cylinder serial number from the free end to the power output end;

(b) When the cylinder is numbered in more than two columns, the column number is determined first, from the power output end to the free end, with the horizontal line perpendicular to the center line of the output axis as the basis, and the number of columns from the right end of the horizontal line is counted counterclockwise. Cylinder numbers are sequenced from the free end of the column.
