The main technical parameters of Marine diesel engine structure are introduced

There are many types of diesel engines, and the specific structure is not exactly the same, but it is basically composed of the cylinder head mechanism, the crank connecting rod mechanism, the valve mechanism and the air exchange system, the fuel supply system, the lubrication system, the cooling system and the starting system.

The diesel engine is composed of the body, two major mechanisms (crank linkage mechanism, valve mechanism), and four major systems (fuel supply system, lubrication system, cooling system, and starting system). The body is the frame of the diesel engine, which is composed of the cylinder block and the crankcase. The crank connecting rod mechanism is composed of piston connecting rod group, crankshaft flywheel group and other parts.

What are the main technical parameters of diesel engines

The main technical parameters of diesel engine are:

1. Structural parameters, cylinder diameter, cylinder volume, compression ratio, length, width and height data of the body, net weight of the body, suitable temperature environment, cooling mode, etc.

2. dynamic indicator, power size, torque size, speed limit,

3. economic indicators, fuel consumption, refers to the diesel engine no-load and load respectively fuel consumption value, suitable lubricating oil (oil) label, exhaust gas emission and suitable for environmental standards.
