2.1 Design Philosophy
The generating set is a power generation device with the gas fuel as the power source, and the thermal power is converted into electric energy by the ignition engine. Equip cooling system, lubricating system, fuel supplying system, control system, power output, parallel, common base. Able to work with low pressure, high pressure gas and liquid fuel.
Connect the gas engine to the alternator with flange and install on the welded common base. Set shock mitigation system to eliminate the vibration when running.
Unit control system group use the control module DEEPSEA or ZONGZHI Generator set and set on the common base.
Set the gas valve integration group on the common base, include Manual cut-off valve, pressure gauge, filter, pressure regulating valve, safety electromagnetic cut-off valve, flame blocking device.
Gas engine: using Cummins 6CT diesel engine as base machine, high energy sequential ignition, Gas specific debugger, all parts of control system are from the well-known brand in the word.
Alternator: jiangsu lingyu self excitation brushless AC synchronous generator

2.4. Formation of Mixed Gas
Air will be filtered from the dry type filter of engine.
pressure regulating valve evenly supply gas and mix via proportional mixer.
Exhaust gas turbocharger compress mixed gas to improve the engine charging efficiency.
using oil cooling or water cooling double cooling booster to ensure booster regular works.
inner cooling system
using air to air or water to air inner cooling to reduce the mixed gas temperature, increase the density and improve the engine efficiency.
2.5. Engine Ignition Management System
After the control system of the muti-point sequential ignition engine collects the position signal of the camshaft, it controls the ignition coil to fire in sequence
The ignition time and ignition energy can be accurate via programming the Map
Equip high energy ignition coil for each cylinder
Self-learn Function: ECW will self-correct the running parameter via temperature sensor, pressure sensor and throttle position signal.
