2. General Technical characteristics of 2C16V165RQ Gas engine

 

 

The 16V165RQ gas engine is the same as the 396 series diesel engine with the following two major features:

 

-Optimal performance

 

The 16V 165RQ engine occupies the leading position in specific power, that is, high power, light weight and compact structure. Advanced technology is adopted in the fierce technology competition, which makes the range of engine characteristic wide.

 

 

-Advanced and practical solutions

 

Continuous research and development to ensure a leading position in engine technology. Make the user get maximum operation economy and reliability.

 

Advantages of 16V165RQ Gas engine

 

Long-term technical experience and information feedback in a wide range of areas show that the cost of the engine throughout its life cycle has been significantly reduced. In particular, there are three main factors that play a decisive role in engine running economy:

 

Long-term practice has proved that the combination of use and daily maintenance can simplify the maintenance work and improve economic efficiency. Preventive maintenance ensures high engine efficiency and avoids costly downtime losses.

 

Low consumption throughout the entire operating range, the main operating costs of gas, lubricating oil costs at the lowest level.

 

-Integrated accessories and standardized interfaces

 

 

The manufacturer may provide a complete set of power plants with the following characteristics:

 

You do not need to select and configure attachments separately.

The manufacturer is responsible for providing complete sets of equipment and auxiliary devices.

 

-Light weight and compact size

 

Reduce transportation, handling and warehousing costs.

The installation foundation is simple, reducing the mechanism space and the installation reservation port.

Meet strict requirements on power , weight and space . 

 

-A series of design ideas

 

Universal interface and parts to rationalize and systematize application and engineering installation.

 

3. Technical Features of Monitoring and Control system for 3C16V165RQ Gas engine

 

The monitoring and control system of 16V165RQ gas engine has the characteristics of integrated regulation, control, self-inspection and safety protection.

 

(1) Electric Control system of 1D 16V165RQ Gas engine

 

Referring to the advanced technology of the electronic management system of MTU diesel engine in Germany and combining the characteristics of coal-bed methane (gas) unit, the control instrument box beside the machine is developed, which integrates operation, display, security and data communication as one electronic control system. Having the following characteristics:

 

machine - side operation-For better protection of gas engine and convenient maintenance, special addition of pre-supply, wheel and emergency stop and other operations.

 

Show-It is a multifunctional liquid crystal display screen, which can display all kinds of operation parameters, automatic protection alarm and state display of coal bed methane (CBM) machine.

 

security guard-The oil pressure, mixed inlet pressure and cooling water temperature are monitored. When the set value is exceeded, the system sends out sound and light alarm and takes corresponding protection measures to complete the task of protecting the gas engine.

 

After data processing, all parameters of the gas engine are uploaded to the upper control computer via RS485 (or 422) serial port.

 

(2) the combustion control system of 16V165RQ gas engine


Adopting EGS-02, the world's most advanced electric control technology of coalbed methane (CBM) of WOODWARD company, can fully meet the requirements of low concentration coal mine gas. Its characteristics are as follows:

 

-The 16V165RQ gas engine adopts the most advanced EGS-02 air-fuel ratio control system of WOODWARD Company, Tecjet gas flow control valve and WOODWARD electronic speed control system, and ProAct-ITB digital integral throttle, Venturi mixer. The Control system of Coal bed methane (Gas) intake on the site

 

-EGS-02 is the latest coal-bed methane (gas) electronic control system of WOODWARD company. It is an intelligent and high-precision coal-bed methane control system. It can realize closed loop control of air-fuel ratio, make 16V165RQ gas engine realize real lean combustion, select WOODWARD electronic speed control system, make the unit run more smoothly, reliably, and control more accurately.
