Our company’s specialists arrange delivery and installation of the unique diesel diagnosis systems

The system is supplied:

• as a stationary on-board complex for continuous control of the engine by designated staff;
• our company’s engineers may execute express diagnosis of engine’s condition using portable version of DDS complex.

DII’s Combustion Engine Monitoring System (DII-7) has been developed to monitor reciprocating engine performance parameters by means of electronic sensors installed in the cylinders. The portable version is designed for short-term, temporary use, such as periodic testing and adjustment. The permanent complex is used for continuous monitoring of combustion process inside every cylinder. 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. As per client’s request the permanent complexes may be additionally equipped with the main and crankpin bearings’ temperature sensors, exhaust gases temperature and other sensors. The system may also be coordinated with the main engine control system for control of revolutions or emergency stop upon detection of critical parameter.

Main 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 DII-7 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).
• Absolute and relative Parameter baselines will be established for each engine type.

Based on the monitoring data the DII-7 will issue immediate Advice for improved engine loading and tuning.
