美国Dynalco AF-900PC Air/Fuel Ratio Controller 空燃比控制器

AF-900PC Air/Fuel Ratio Controller 空气/燃料比例控制器

Product Code: AF-900PC

Description：
AF900PC空燃比控制器采用先进的微处理器控制器，在不使用气动转换器的情况下精确地保持自然吸气和涡轮增压汽化气体燃料发动机的空燃比。加热型氧传感器确保发动机的空燃比控制从起动起就得到控制。它有一个大的字母数字背光显示，易于阅读和车载数据记录包括和易于下载的长期数据存储。CSA Class1，Division 2认证。The AF900PC Air/Fuel Ratio Controller uses an advanced microprocessor controller to precisely maintain the air/fuel ratio of naturally aspirated and turbocharged carbureted gaseous fueled engines without the use of pneumatic converters.Heated O2 sensor ensure that the engine’s air/fuel ratio control is being controlled right from start up.It has a large alpha-numeric backlit display for easy readability and on-board data logging is included and easily downloadable for long-term data storage.CSA Class1, Division 2 approved.

Product Data Sheet
November 2010 Instrumentation & Controls
Air/Fuel Ratio Controller
The AF-900PC Air/Fuel Ratio Control System was designed by Dynalco's customer-driven research
and development team for rich-burn engines.
Utilizing heated O2 sensor(s) in the exhaust stream (one per bank), the AF-900PC provides PWM
outputs to full-authority fuel valves in order to accurately control air/fuel ratio over a wide load range.
The AF-900PC implements this control through an intelligent closed-loop algorithm which provides
smooth behavior adaptable to changing engine load, speed, fuel quality and ambient temperature /
pressure.

The AF-900PC is also equipped with optional intake manifold pressure sensor(s) capability to maintain
emissions over an even wider range of engine loads and operating conditions.
Programming of system parameters is performed using the Dyna-Host software. The use of the front
keypad will also allow parameter changes and diagnostics information. These multi-functional keys
assist in navigating through the numerous screen levels on the LCD.
The AF-900PC system monitors the proper operation of all sensor inputs and controller outputs,
flagging errors and changing its operating mode when a fault is detected. The system also provides
Modbus communications to provide real-time controller information for your PLC or SCADA system.
Data logging of critical parameters is stored via onboard flash memory.
The AF-900PC Air/Fuel Ratio Control System utilizes
heated O2 sensors and full-authority fuel valve control to
precisely maintain the air/fuel ratio of rich-burn carbureted
gaseous fueled engines.
