Chinese MTU165RQ gas genset, Power 550KW-1100KW

As the well-known EPC company in China, North International General Machinery Holding Limited can provide users with generating set and EPC contract services of diesel engine, gas engine, gas turbine and power station.

Introduction of Gas Genset

16V165RQ gas engine is designed and developed based on the Germany MTU 16V396 permit diesel engine, has good power performance, economical efficiency, safety and reliable running, convenient operation and maintenance and long life characteristics.

Mainly used for natural gas, CBM, landfill methane, etc

This design keeps Germany MTU engine main structure unchanged, designs and develops the gas distribution system, air intake system and combustion system, gas control system, ignition control system and control of motor speed control system and other special system and its components according to the characteristics of the fuel gas combustion

Characteristics of design

2.1 Bypass circulatory system

Ensure the heat balance of internal combustion engine doesn’t change because of the diesel fuel oil change into gas, in favor of all the moving parts of the gas machine to keep the original design of the best working state

2.2 Closed (double circulation) cooling water system

With both high and low temperature two way water-cooled circulation system technology, 165RQ MTU can ensure the temperature of turbo air be lower and stable, this makes we choose the cooling type of Gas Genset more flexible.

2.3 Germany MTU company efficient technology of plate heat exchanger

The integrated design of Plate heat exchanger and Machine with cooling water pump reduces the unit volume and increases the operation reliability.

2.4 Germany MTU proprietary double water-cooled walls supercharger, the exhaust pipe wall technology system of three layers

The whole thermal radiation of machine is only 45kw, reduces the heat radiation outward, increases the volume efficiency to ensure efficient pressurization. It reduces the amount of radiant heat unit and room temperature, without bare high temperature parts, increases the safety of the unit operation.

2.5 Germany MTU cylinder head and four valve spinning technology

It makes the inlet and exhaust more smoothly and forms more small vortices, more conducive to mixture combustion

2.6 Germany MTU split type piston

The design of steel head and aluminum alloy bottom reduces the inertia force of the piston, improves the corrosion resistance and bearing capacity on the top of the piston. The design of deep pit/low clearance increases the torque, improves the combustion efficiency, cooling effect and the reliability of operation of piston, reduces the fuel consumption and Implements the lower emissions with the oil nozzle cooling.

2.7 Germany MTU high intensity of cylinder body setains the German MTU16V396 series diesel engine alloy cast iron with the body
