Meaning of the marine diesel engine 8300ZLCzA 4 model

Eight-cylinder inline four-stroke, bore 300mm, water-cooled, supercharged, marine, variant symbol A.

Diesel engines have high thermal efficiency, good economy, easy starting, and great adaptability to all kinds of ships, and are quickly used as ship propulsion power after they came out. By the 50s of the 20th century, in newly built ships, diesel engines almost completely replaced steam engines. Marine diesel engines are already the main power source for civilian ships, small and medium-sized ships and conventional submarines (see Ship Power Plant).

Marine diesel engines can be divided into main engine and auxiliary engine according to their role in ships. The main engine is used as the propulsion power of the ship, and the auxiliary engine is used to drive the generator, air compressor or water pump, etc.

Marine diesel engines are generally divided into high-speed, medium-speed and low-speed diesel engines, and the main performance indicators of three types of diesel engines are listed in the table.

8-8 cylinders. 300 - bore 300 mm.

ZL - In-line.

c-Marine. Z-Boost.

The final "A-4" is set by the manufacturer itself, and it is estimated that it means:

A-Model variant code, usually indicating a strengthened machine.

4-Model development number, which indicates the code of single-cylinder power, such as "-1" single-cylinder power of 180kw, "-4" single-cylinder power of 200kw

I am doing marine diesel engine design, I hope my opinion will be helpful to you.

Eight-cylinder inline four-stroke, bore 300mm, water-cooled, supercharged, marine, variant symbol A.

Eight-cylinder engine, 300mm bore, supercharged intercooled, marine machine, with the custom name of the machine on the back.

Wuxi Antai Diesel Engine, Guangzhou Diesel Engine, and Ningbo Zhongce Group all have this diesel engine.

Zibo Z6170 marine diesel engine is a Z6170 marine diesel engine produced by Zichai Diesel Engine Factory.

In-line, four-stroke, direct injection, exhaust gas turbocharging, air intercooling, air motor or electric motor starting. Bore: 170mm Stroke:

I don't know what z means 6170 in 6 is the meaning of six cylinders, and 170 is its bore.

1) 8E150C-1: 8 cylinders, in-line, two-stroke, bore 150mm, coolant cooling, marine main engine, right engine basic type (1 is the distinguishing symbol).

2) JC12V26 32ZLC: 12 cylinders, V-type, four-stroke, bore 260mm, stroke 320mm, coolant cooling, supercharged intercooler, marine main engine, right engine basic type (JC is the **** code of Jinan Diesel Engine Co., Ltd.).

3) G8300 380ZDZC: 8 cylinders, inline, 4-stroke, bore 300mm, stroke 380mm, coolant cooling, increase.

Pressure reversible, marine main engine, right engine basic type (G is the series**) - China water transport market network.

I really don't want to be a water army, but I still didn't hold back, so I just took the water, and there are many models of ship hosts. There are two-stroke machines, four-stroke machines, depending on what kind of boat you have. Fishing boats, yachts, oil tankers, cargo ships, cruise ships, ** and so on These ships have different requirements for the main engine of the ship, so the question you asked is a little watery, and my answer is also a little watery.

Hehe! ~

The main engine type is not required by the shipowner, but is based on the hull and propeller fit.

The main engine of a ship, that is, the power plant of a ship, is a machine that provides power for all types of ships. According to the nature of the fuel, the place of combustion, the working fluid used and the way it works, the main engine of the ship can be divided into steam engine, internal combustion engine, nuclear power engine and electric motor.

There are many manufacturers at home and abroad for various types of main engines, and the models are numerous, and they are generally required by the shipowner himself.
