Combustion Research Unit

CRU

The CRU is the ideal tool for characterization of fuels ignition and combustion properties.
From a small amount of fuel sample, a user defined test program covering of up to 20 different physical conditions can be run. This product is used within development of diesel fuel-compositions and additves for optimization of diesel fuel. 

CRU

Testing over a range of conditions may reveal more information about the specific fuel or additive than a single point test which is typically used for determination of Cetane Number. Cetane Number instruments are typically testing at a pressure and temperature condition equal to low load in a modern Diesel Engine.

This way CRU has successfully been used as a tool for screening fuel additives and diesel fuel components, prior to the much more expensive and time consuming Engine tests.

Standard Edition CRU Features

  • Common rail type Diesel Injector with electronic control of injection pressure and injection duration
  • User friendly Software which supports user defined test program with up to 20 test conditions
  • Charge mixing/EGR simulation
  • Reliability, high precision and long term stability proven through years of operation.

Additional features for Standard Edition CRU

CRU – Standard configuration

The standard Edition CRU comes with a multi-hole automotive common rail diesel injector and a combustion chamber geometry suitable for the wide spray pattern. The user software supports user defined test program consisting of up to 20 physical conditions per sample, and a software tool for analysis and presentation of the results.

The charge mixing feature automatically blends in a user defined fraction CO2 or other inert gas to reduce O2 content of charge. This is a useful feature for mimicking EGR (Exhaust Gas Recirculation) in a diesel engine.
