AIR/FUEL RATIO GRID DEVELOPMENT
Balancing emission rates and fuel consumption for optimum engine performance.
Optimum engine performance requires operators to know and understand the operation of their equipment. Key measurements include brake-specific fuel consumption and emission rates of the engine. Accurate operating grids ensure a fuel-efficient compliant engine and are major components of a maintenance alarm system.
Program DescriptionUsing empirical engine performance data collected over the operating range of the unit, air ⁄ fuel mixture grids and critical engine algorithms are developed. Program features include:
- Onsite testing (up to 48 hours to collect engine performance data)
- Computer-generated air ⁄ fuel mixture grids
Where Testing is ApplicableTesting is applicable to equipment where fuel consumption and emission rates are valuable; this may include units that have broad operating ranges, engines with predictive maintenance systems, and equipment that is to be operated optimally.
Note:When used in combination with a control system, air &frasl ;fuel mixture grids can be used to automatically maintain the optimum mixture as operating conditions change.
