General System Description

DII’s Combustion Engine Monitoring System (DII-7) has been developed to monitor reciprocating engine performance parameters by means of electronic sensors.  The system can be used in two modes:

Portable - for short-term, temporary use, such as periodic testing and adjustment

Permanent - for continuous monitoring

Using the system helps to spot engine malfunctions at an early stage, yielding benefits in proper preventive maintenance scheduling, emergency avoidance and engine overload protection.  Use of the DII-7 system will assure your Power Plant improved reliability and efficiency.

Features

• The monitoring system captures Combustion Pressure Fundamental Measurements for all engine cylinders, using built-in pressure sensors, during one working period, which is critical for combustion engines due to variable loading conditions.
• Based on the Fundamental Measurements curve, the system will compute common Working Process Parameters, per cylinder, per cycle and overall power and fuel consumption. 
• The additional non-permanent pressure sensor provided can be used for auxiliary engine checkup and tuning.
• The vibration channel presents fuel injection and exhaust timing (for lower speed engines).  The same sensors can be used for vibration diagnostics of auxiliary equipment (pumps, gears, etc).
• Parameter baselines will be established for each engine type.  DII will assist the customer in establishing their system baselines.
• Based on the monitoring data the DII-7 will issue immediate Advice for improved engine loading and tuning.  Alerts and user-defined warning-signals are also generated.
• All measurements and warnings are recorded and stored in the system Archive for Home Office Engineering Data Analysis.
• The system is capable of sending the data to a Remote Office. Home Office engineers will be able to track the changes in engine loading and conditions (including fuel consumption for the engine).
• The System can be extended to interface with external sensors (exhaust temperature, etc.).
