OCTANE ANALYZER laboratory systems

PDF

ESD Laboratory Systems have been developed specifically for determination of the octane number (ON) of a fuel sample. They require the fuel supply bowls to be filled manually, as prompted by the computer. Sequencing through the test cycles and calculations required for ON determination is controlled by the analyzer software. Immediate display and hard copy reporting of test parameters and results are comprehensive and customizable. Laboratory systems suitable for a wide range of applications are available.

 

COMPLIES WITH:

 

  • ASTM D2699, Standard Method for Research Octane Number of Spark-Ignition Engine Fuel
  • ASTM D2700, Standard Test Method for Motor Octane Number of Spark-Ignition Engine Fuel

semi-automatic lab system

The Semi-Automatic Analyzer is a six-bowl fuel supply system with solenoid controlled dump control for each bowl. Supply bowls are manually filled to appropriate levels prior to testing.

Manual Laboratory System

The Manual Laboratory Analyzer comes equipped with three sample fuel supply bowls which must be manually emptied and refilled.

FEATURES INCLuDE:

GENERAL:
  • Reduces octane giveaway that affects profitability.
  • ASTM D2699 and ASTM D2700 compliant.
  • Wit the proper fuel bowls, our Manual Lab System can perform octane ratings with all three ASTM D2699 and D2700 Procedures: A (Bracketing - Equilibrium Fuel Level), B (Bracketing - Dynamic Fuel Level) and C (Compression Ratio).
  • Always finds correct fuel / air ratio adjustment.
  • Frees operator from continual fuel / air adjustment.
  • Far superior testing of octane than manual means.
  • Minimizes operator transcription errors (all data is handled by computer).
  • Each engine has its own terminal from which the operator initiates sample analysis. Supervisory operations can also be performed from the engine terminals.
  • Runs tests on multiple engines simultaneously. ESD has installed systems with up to 14 engines.
  • 0.06 to 0.08 typical standard deviation.
  • Includes automatic temperature control based on digital temperature input monitoring for air intake and mixture temperatures for all engines.
  • No moving parts, increasing reliability.
  • Minimal maintenance; can be accomplished by in-house personnel.
  • Water-cooled aluminum block brings fuel temperature down to ASTM requirements.
  • Multiple product bowls with automatic sequencing via computer-controlled solenoids speeds up analysis and elminates errors.
  • Two bowls dedicated for reference fuels and four bowls are available for product samples.
  • Bowls swing out of way quickly, giving access to the engine for maintenance.
  • Top cover on bowl reduces evaporative losses.
  • Delivers customized hardware and software.
  • COMPREHENSIVE REPORT GENERATION.
  • ENGINE PARAMETERS / ALARMS & WARNING LIMITS.

 

SOFTWARE & PROGRAMMING:
  • An interactive screen program though which the operator, at the engine, enters information about the samples to be analyzed. All other factors are stored in the system and can only be changed under a supervisory menu. Examples: PRF octane numbers to be used, sample ID. The reduces the probability that the operator will enter something in error.
  • Application programs written in DecisionPlus and C++ to operate the system at each engine.
  • A supervisory menu which lists the supervisory programs. These include, but are not limited to, features that are not normally available to the operator, such as: viewing and editing historical octane rating result records, printing reports, viewing alarm logs, and performing system calibrations. The system keeps history of all octane ratings that have been performed since installation.
  • A continuously running scanner program to read and control all the analog and digital signals at high speed. A moving average is maintained on all variables resulting in precise, noise-free data acquisition.

 

HARDWARE:
  • Mounted at each engine is a stainless steel instrument cabinet with viewing window. This contains signal conditioning modules for knock signals, RTD temperature sensors and oil pressure.
  • Includes UNIX-based system for high reliability, reduced costs and ease of expansion.
  • 300 gigabyte RAID hard drives for program and data reliability.
  • Color printer for reports.
  • Uninterruptible power supply for entire system.

 

ENGINEERING INSTALLATION:
  • Professional installation and startup will be performed by Electronic Systems Design field engineer(s). Optionally, a software engineer may also be on- site, if needed, during startup and commissioning. (This will be determined on a site-by-site basis.)
  • Operator and supervisory training is included, which will be done during the installation phase. Our policy is to stay on-site until the project is complete and the customer is satisfied that all training has been done and everything is working properly. If there is a problem during the first twelve (12) months that your staff cannot resolve, we will make a return trip at no charge.
