Automatic Reference Fuel Blending System

The Koehler Automatic Reference Fuel Blending Unit with 6 tanks is used for the automated preparation of cetane and octane reference fuels and standardization fuels for  Octane Test Engines and Cetane Test Engines according to ASTM D2699, ASTM D2700, ASTM D2885, and ASTM D613.

The Koehler Reference Fuel Blender prepares the reference fuel blends by weight using a precision balance based on the ASTM test methods. With the automatic calculation and control program, a high precision balance delivers an accurate and reliable fuel blend value with the precision of 0.01 g.

The professional software controls all blending processes and makes blending operation simple. The operator only needs to select the standard method, input the target octane/cetane number and sample volume, and start blending. The fuel blend is delivered automatically. The blend data is automatically saved on the computer. A free blending function is offered for special fuel blending for special engines.

  • Suitable for long-lasting, error-free octane/cetane rating operation
  • A high-precision balance is used for gravimetric measurement to improve precision of octane/cetane results
  • The touch screen panel with easy to use software simplifies the blending operation process
  • Automatic calculation program controls the entire blending process to eliminate human error and improve efficiency of cetane/octane number tests
  • Fuel temperature and blending material level in tank are monitored in real time
