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 Engine and Cetane Test Engine 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 process and makes blending operation simple. The operator just needs to select the standard method, input the target octane/cetane number and sample volume, 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.
