Description 4MW MAN Diesel generator set 4300GF9-K

Are you still wasting time looking for Industrial Diesel Generators - Prime, Standby, Continuous power suppliers?
Do you still worry about product quality assurance?
Are you late in deciding to buy because of insufficient budget?
If you have these worries, stay and see.

4MW MAN industrial Diesel generator set 4300GF9-K
MAN 40 series engines are well received by users of power equipment such as inland river navigation, dredging project, offshore oil equipment manufacturing, Chinese port construction and large-scale power station.
MAN 40 series engines are equipped with high-quality generators to meet the demand. The specific models are as follows：

MAN engines, under the same cubic capacity with much higher output power and much better environmental protection performance have been the representative particular for MAN generating sets application. They can satisfy with the harsh requirement of the generators and were developed under the newest technology study. This promised the absolute reliability, usability and economy during their operations. These are the strongpoint for those MAN generating sets manufactures and similar operators. In addition, MAN engines have much more merits to mention in the environmental protection aspect, such like their gas exhaust and noise discharge are the best among those engines. Herein according to the comparatively strict environment law and regulation, the diesel engine will play a very important role and those industrial department will benefit from the application of those high-speed diesel engines.


Main important parts - MAN industrial Diesel generator
(1) Airframe
The overall rigid design concept, the main bearing bolts run through the whole body, and the unique main bearing tie bolts, so that the entire body can withstand higher compressive stress, increase the overall safety factor, the entire body inside the waterless cavity, anti-corrosion, Prevents the lubricant from mixing with the cooling medium and is easy to maintain.
(2) Cylinder liner
It consists of three parts: cooling water jacket, fire shore ring and cylinderliner, which can effectively prevent deformation, reduce the heat load of
related parts, have high cooling efficiency, ensure uniform temperature of components and prolong its service life. A separate cylinder lubrication mechanism reduces oil consumption.
(3) Piston
The unique stepped piston cooperates with the fire shore ring to keep the carbon deposit on the top of the piston away from the running face of the cylinder liner, thus avoiding the reduction of the oil film adhesion of the cylinder liner and the deterioration of the oil. The shape of the combustion chamber is optimized to make the fuel atomization effect better, the oil and gas can be fully mixed, and the combustion is sufficient, thereby reducing the fuel consumption rate and the smoke.
(4) Link
The connecting rod is composed of a rod body, a connecting rod big head upper cover and a connecting rod big head lower cover, which reduces the lifting height, facilitates increasing the connecting rod shaft diameter and increasing the crankshaft strength.
(5) Cylinder head
The reasonable structure can withstand higher burst pressure, and the efficient and smooth intake and exhaust channels can optimize the
intake and exhaust effects, make combustion more complete, and reduce fuel consumption and smoke.
The water is used to cool theexhaust valve seat to reduce the heat load of the valve seat and prolong
the working life. In addition, the intake and exhaust valves use a unique rotating device to reduce the carbon deposits in the intake and exhaust valves and the seat, thus ensuring a good seal and a long working life.
(6) Advanced turbocharged intercooling system
Using MANs advanced turbocharger, it provides an efficient boost matching solution. The pressurized fresh air is cooled into the
combustion chamber through two stages of intercooling. The larger capacity intercooler reduces the intake air temperature and combustion temperature. Greatly reduced NOx emissions.
(7) Safety control system
Adopt SaCoS safety control system produced by MAN to ensure trouble-free operation of the engine.
