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.
