Top Quality Generator 8 Cylinders Weichai Marine Diesel Engine Man L32/40 4000kw 750r/Min

Reliable, quiet and durable power

The L32/40 series marine diesel engine is introduced by Weichai and the world's first marine diesel engine brand German MAN through a license agreement. The body of this series of products adopts an overall rigid design, which is highly safe; the cylinder unit is assembled as a whole, easy to load and unload; The company's advanced turbocharger and secondary intercooler have excellent air intake performance, and adopt the AT2000 safety control system produced by MAN, with high reliability.

high performance

The MAN engine adopts the technology of the German MAN company, which is advanced in technology. It can use various fuels such as MGO, MDO, and HFO. It has strong adaptability. According to the operating conditions of the engine, it provides the optimal supercharging system matching scheme, which can run continuously with heavy oil. Diesel engines can run continuously at a load of more than 20%, and even when the load is below 20%, they can run for a limited time. Can deal with a variety of complex working conditions.

fuel efficiency

In terms of fuel, reducing fuel consumption and increasing power is one of the important goals of MAN diesel engine design. Diesel engine operating parameters such as fuel injection time, injection pressure or intake and exhaust valve control time not only affect the fuel consumption rate but also affect the emission index. MAN has further reduced the fuel consumption rate by continuously optimizing the thermodynamic model and structure of the diesel engine, and also made the diesel engine emission performance better.
 

Structural features
The overall rigid design concept, the main bearing runs through the entire body, and the unique main bearing side pull bolt design is used to make the entire body withstand compressive stress and increase the safety factor. There is no water cavity in the whole body, which is convenient for maintenance. The cylinder liner has a dynamic land ring structure, consisting of a cylinder head and a cylinder liner, which can effectively prevent deformation, reduce the thermal load of the related parts, and prolong the service life. Adopt independent cylinder lubricating mechanism to reduce oil consumption. The unique stepped piston design, combined with the fire land ring, makes the carbon deposits on the top of the piston run away from the cylinder liner, avoiding the reduction of the adhesion of the cylinder liner oil film and the deterioration of the oil.
Technical advantages
Connecting rod: The connecting rod is composed of three parts: connecting rod body, connecting rod big end upper cover and connecting rod big head lower cover, which reduces the hoisting height, facilitates the enlargement of the connecting rod journal and increases the strength of the crankshaft. Supercharged and intercooled: MAN's advanced turbocharger is used to provide the optimal supercharging matching scheme; the secondary intercooler is used in the intake process to accurately and quickly control the intake air temperature. The intake and exhaust are designed with a unique rotating device, which reduces intake and exhaust valves and carbon deposits, ensures the air tightness of the valve, and prolongs the working life. At the same time, all the large bolt connections of the 32/40 diesel engine can be tightened or loosened with several special hydraulic tensioning tools, which is convenient for maintenance and loading and unloading.
Perfectly lubricated
The 32/40 type diesel engine can achieve a continuous extremely low oil consumption rate because it adopts the following advanced technologies: 1. Forced lubrication of the friction surface of the cylinder. 2. Adopt water-cooled combustion ring and stepped piston design. 3. Stable chemical properties, low friction chromium-ceramic piston rings. The application of the above advanced technology has created an unparalleled oil consumption rate of 32/40 diesel engine: 0.5g/kw.h. The design optimization of the oil consumption rate is to eliminate the need to periodically re-slip the lubricating oil, and there is no need to worry that the oil will be carbonized, which reduces the cost of oil use and the emission of pollutants.
Environmentally friendly
In order to comply with the most stringent NOx requirements, the MAN design house selectively uses catalytic reduction technology for 32/40 engine fuels. Meet the Tier I requirements of the International Maritime Organization (IMO) for engine emissions, and can be upgraded to Tier II, and obtained the world's top ten classification societies LR, GL, DNV, BV, ABS, CCS, NK, RS, RINA, KR Engine Type Approval Certificate.
quality
The perfect marine powertrain system solution of German MAN Company is perfectly combined with Weichai's professional and efficient service network to provide Chinese customers with power beyond their dreams while strictly guaranteeing quality.
