manual laboratory system


The Manual Laboratory Octane Analyzer System is used in conjunction with your Waukesha CFR test engine. It is particularly appropriate for use when small numbers of fuel samples are to be analyzed.

The system utilizes the Falling Level Method, the Dynamic Level Method as described in ASTM D2699 and ASTM D2700.

This system comes equipped with three sample fuel supply bowls as shown in the image. With these, the operator will fill two of the bowls with primary reference fuels (PRF). The remaining bowl is manually filled with the sample fuel. The operator then starts the system and the fuels are manually fed to the engine, in sequence, until the maximum knock intensity for each is determined. At this point, the octane number of the sample fuel is calculated and displayed.

If a two pass analysis is required, as per ASTM D2699 and ASTM D2700, the bowls must be manually emptied and refilled. The operator has the option to repeat, delete or add additional runs on any of the bowls.

This analyzer is based upon using a central computer to handle as many engines as are required. In order to run multiple engines, a multi-user operating system is supplied.

features INCLUDE:

  • Reduces octane giveaway that affects profitability.

  • ASTM D2699 and ASTM D2700 compliant.

  • With the proper fuel bowls, our Manual Laboratory System can perform octane ratings with all three ASTM D2699 and ASTM 2700 Procedures: A (Bracketing - Equilibrium Fuel Level), B (Bracketing - Dynamic Fuel Level) and C (Compression Ratio).

  • Always finds correct fuel / air ratio for maximum knock.

  • 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 operation can also be performed from the engine terminals.

  • Runs tests on multiple engines simultaneously. ESD has installed systems wih 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.

  • Top cover on bowl reduces evaporative losses.

  • Delivers customized hardware and software.

  • An interactive screen program through which the operator, at the engine, enters the 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 IDs. This reduces the probablility that the operator will enter something in error.

  • 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 a complete history of all octane ratings that have been performed since installation.

  • Application programs written in DecisionPlus and C++ to operate the system at each engine.
  • 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.

  • 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.

  • 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 supervisor 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.
