Over deze norm
This CEN Workshop Agreement specifies those properties of pure plant oil (PPO) that are at least necessary to achieve smooth deployment of this fuel in diesel engines with/without exhaust gas after-treatment, compatible for PPO combustion. In this document two pure plant oil fuel classes are defined. These are effectively tailored towards use in diesel engines without and diesel engines with exhaust gas after treatment (catalyst, filter). Both classes are intended for, but not limited to, use in heavy duty vehicles . The specification is valid at the point of delivery. Since experience for long term and failure free use of PPO compatible combustion engines is limited, this document is not yet a comprehensive specification, but more limited to specific properties. Only those properties that are seen as necessary for minimum quality requirements in the current technical discussion have been included. Any oil seeds can equally be used for the production of PPO, when the produced plant oil fulfils all individual requirements of the properties and limits mentioned in this workshop agreement. This document lays down properties and values for the use of PPO at present deemed necessary, along with the test methods for these properties to be applied. Application of the in this document defined PPO for vegetable oil compatible combustion engines is only allowed when warranties have been given accordingly from the engine or equipment manufacturer. Further properties can be included in later versions of this document as they become available form successful technical and analytical test results. The specification is valid at the point of sale. Blending with diesel fuel or FAME is not covered in this edition of the CEN Workshop Agreement. If the need arises for blends of PPO with diesel a revision process will be considered.
