ACE SYSTEM (Advanced Combustion Engines)

What is the ACE (Advanced Combustion Engines) System proposed by Info-Marine?

The ACE System proposed by Info-Marine is a cutting-edge technology designed to assess the condition and performance of 2-stroke and 4-stroke marine or industrial diesel engines. It uses a variety of sensors and analytical tools to provide a comprehensive analysis of engine health and efficiency, helping to prevent serious engine failures and unplanned downtimes.

What kind of measurements does the ACE System perform?

The ACE System performs several crucial measurements, including:

Combustion Pressure: Utilizing a pressure transducer to calculate the indicated power from each cylinder and assess the combustion process.

Vibration Measurements: Employing an accelerometer and ultrasonic sensor for a thorough mechanical assessment of the engine.

Engine Balance: Analyzing the results with internal software and skilled engineers.

Engine Working Parameters: Collecting and comparing all engine parameters with received sea trials for a deeper assessment.

Comprehensive Analysis: Providing in-depth analysis and recommendations based on collected measurements.

When should ACE measurements be performed to prevent engine failures?

ACE measurements should be performed in various situations to prevent engine failures, including:

1. Prior to engine overhaul.
2. After a major overhaul.
3. During an annual preventive engine performance check.
4. When changing the maintenance strategy from planned to condition-based.
5. In response to problems with engine power and temperature balance.
6. When there is an increase in fuel consumption.
7. When disturbing engine symptoms are observed.
8. For regulatory compliance purposes.

What is the One-Time Measurement System, and what are its benefits?

The One-Time Measurement System is a service offered by Info-Marine, suitable for reciprocating machines, where the installation of the measuring system is temporary and conducted by a service engineer. The process takes about 10-15 minutes, and the measurement process can take up to 1.5 hours per engine. Benefits include:

Suitable for 2- and 4-stroke engines.
Simple and fast installation.
High-quality measurements performed by qualified service engineers.
Comprehensive diagnostic service and data analysis.
Detailed PDF reports with recommendations.
Control check of engine condition before and after overhaul.
Possible ABS approval for overhaul extension.

How does the Periodic and Continuous Based Measurement System (CBM) work, and what advantages does it offer?

The Periodic and Continuous Based Measurement System (CBM) involves the permanent installation of the measuring system on the engine, conducted by Naviserv's service engineers. The crew is trained to perform necessary measurements and data transfer for analysis. Advantages include:

Suitable for 2- and 4-stroke engines.
Permanent or temporary system installation.
Crew training for conducting measurements.
Comprehensive diagnostic service and data analysis.
Detailed reports with performance improvement recommendations.
Cost reduction through crew-conducted measurements.
Continuous monitoring of engine condition.
Regular measurements at intervals (usually every 90 days).
ECM app for digital report access.
ABS approval for maintenance period extension.
Reduction of sudden failures through constant monitoring.

What components are included in the ACE measurement system, and how do they contribute to engine diagnostics?

The ACE measurement system includes several key components:

Analyzer: A rugged device that collects all measured data.
Pressure Transducer: Measures pressure changes during the combustion process.
Accelerometer and Ultrasonic Sensor: Diagnose vibrations and the condition of moving parts, such as inlet & exhaust valves, injectors, fuel injection pumps, cylinder liners, piston rings, camshaft bearings, and main bearings.
Encoder: Synchronizes all measurements with engine RPM using a magnetic pickup (permanent) or reflective tape (temporary).
These components collectively enable a comprehensive assessment of engine condition and performance, leading to accurate diagnostics and informed maintenance decisions.
