CNPC JICHAI 4000 Series (1320-2200KW)
L20V1902LT-2type closed-loop electrically controlled external mixing natural gas machine features:
1. Turbocharger pre-mixing technology, where gas and air are sucked in at the same time in the compressor, to be suitable for low-pressure gas,
2. The rarefied combustion technology uses WOODWARDs E6 control system to accurately control the air-fuel ratio. Reach the high - altitude combustion ratio, achieve rarefied combustion
3. The single point injection and air-fuel ratio closed-loop control technology can realize the closed-loop control of the air-fuel ratio (in). The engine can adjust the amount of air and natural gas according to the requirements of different working conditions and different speeds so that the engine can run in the best state.
4. Efficient and reliable design of the intake and exhaust system, the use of advanced high-pressure ratio, large flow supercharger, increase the flow area of the intake pipeline, improve the intake efficiency
5. High efficiency, low resistance and plate type oil cooler to improve cooling efficiency, increase the cooling area of air and lubricating oil.
6. The ignition system with high energy and high reliability is selected to make the combustion of each cylinder of the engine more stable and even.

Control cabinet of the GPU
The control panel is equipped with an imported (COMAP) automatic module
parallel mode / mains and a parallel mode / mains selection button, by which
users can easily adjust the power supply. If the parallel operation function is selected,
five sets can realise automatic parallel operation and automatic parallel switching and automatic
load sharing; if the parallel operation function is selected, it is possible to realise the
automatic switching on of an individual device in parallel and system power setting.
The automatic module is equipped with LED display, with Chinese and English interface
control interface. The current status of the whole system can be displayed in real time, with the functions of
measurement and protection functions for the various electrical parameters of the unit, as well as with various
operating parameters, alarm information and historical data to ensure the safety and reliable operation of the generator set.
safety and reliable operation of the generating set. The module has a telecommunication interface.

The speed and voltage of the genset can be adjusted automatically with an electronic speed control system and an excitation system.
The speed and voltage of the generating set can be adjusted automatically by means of an electronic speed control system and excitation system.
. speed potentiometers and voltage knob can be adjusted. The control panel is equipped with
a float charging device that can utilise the self-generation of the genset to charge the battery.
to charge the battery that supplies power to the control panel.


Container:
Scientific and effective soundproofing design can effectively reduce noise
of the generator to 70-75 dB. Utilisation of flame retardant silencer sponge to ensure the safety of the
power units. In addition to the advantages of standard silent canopy, silent canopy
container type canopy also has the advantages of convenient transport (especially sea transport)
and ease of deployment

Gas engine fuel requirement
1) Gas purification
The fuel gas used by the gas generator set should be purified so that there is no
liquid water and humidity not exceeding 80%. The particle size of impurities should not exceed 5μm and the
dust content should be less than 30mg/m³. The hydrogen sulphide content should be less than 20mg/m³,
and the total sulphur content shall be less than 350mg/m³.
2) Gas requirement
Methane value MN≥85, Low calorific value ≥33.5mJ/m3
3) Gas pressure and temperature
The pressure at the inlet of GPU is 100～400kPa;
Pressure fluctuation rate ≤1kPa/min,
Total fluctuation ≤15kPa。
Fuel gas temperature : 0~35deg.

Acoustic Canopy（one meter 85dB ）

Structural design description:
The internal space is divided into two spaces: engine room and control room, and inspection channels on both sides of the equipment inside the engine room.

Functional description:
1)The container is equipped with a distribution box to provide power to all low-voltage loads in the engine room, such as horizontal radiator fans, control screens, lighting, exhaust (supply) fans (for horizontal distribution), chargers, electric heating (optional), oil pumps, electric heating (optional), and outdoor searchlights. It can also be responsible for controlling related equipment (according to project configuration requirements);
2)Two track suspension beams and a hoist are installed on the top of the engine room, with a lifting capacity of 0.5 tons per beam;
3)Inlet of engine air filter and the engine room are equipped with electric heating devices to avoid freezing and blockage (optional);
4)The floor of the machine room is equipped with an axial drive mechanism for the generator, which enables the generator to detach from the coupling by 200mm. (Optional)
5)If the indoor heating temperature in the machine room is not lower than 5 ℃ deg., an insulation layer needs to be installed under the chassis of the machine room, and electric heating heaters (optional) are used inside the machine room;
6)One explosion-proof acoustic and visual alarm lamp is installed outside each machine room. The lighting inside the machine room is an explosion-proof LED lamp with emergency function. Other equipment and boxes do not need to be explosion-proof (optional).
7)Ladder: Install a simple ladder at a suitable position on the box;
8)Configure the fire protection system in the machine room: Install dry powder fire extinguishers as fire extinguishing devices (standard), and other flame detectors, methane leak detectors, smoke detectors, etc. as optional options;
9)The machine room requires a silent type, with 85dB at 1m.
10)Note: The specific configuration shall be subject to the actual situation of the project.
