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)
AirframeThe 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 linerIt 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)
PistonThe 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)
LinkThe 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 headThe 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 systemUsing 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 systemAdopt SaCoS safety control system produced by MAN to ensure trouble-free operation of the engine.

1. The unique spiral winding structure increases the turbulence effect, and the heat exchange capacity per unit area
is 3-7 times that of the traditional heat exchanger.
2. High heat transfer coefficient, high heat exchanger heat transfer efficiency, good heat transfer effect,
high heat transfer coefficient up to 14000W/m-k, energy saving effect is remarkable.
3. Small size. With only one-tenth of the traditional tube and shell heat exchangers, it takes up less space and reduces
infrastructure and installation and maintenance costs.
4. Using a small clearance design to increase the flow rate, the heat exchanger is not easy to foul, and the use and maintenance costs
are low.
5. Advanced design concept, the length of the heat exchange tube is 3-4 times the height of the cylinder, the material stays longer and the
heat transfer is more fully.
6. Spiral-wound elastic tube bundle design can effectively eliminate pipe vibration and stress due to thermal expansion and contraction deformation.
7. Unique 90 degree connection, heat exchangers all participate in heat exchange,
no dead ends and stagnant areas, reduce fluid resistance.
8. Counter-current heat transfer, asymmetric flow design, in the vapor-liquid heat transfer field has other advantages that can
not be compared with heat exchangers.
