General characteristic
Unleaded engine petrol is a mixture of hydrocarbons with the boiling point in the temperature range of 30 to 215°C obtained from crude oil by distillation and other refining technological procedures. They may contain additives improving their utility characteristics as e.g. oxygen containing constituents, detergent, anti-detonation, anti-oxidation additives, etc.
Application
Unleaded engine petrol is generally used for spark-ignition engines of road motor vehicles. It must not be used in vehicles operated in workplaces and enclosed spaces. Unleaded petrol is mainly designed for modern types of spark-ignition engines equipped with a three-way catalytic converter and controlled by an exhaust gas oxygen sensor except the “Speciál” engine petrol intended as replacement for the leaded “Speciál” petrol for older cars with unhardened valve seats.
Packing, storage, transport
Engine petrol is delivered in railway and truck cisterns or via product pipelines. During the storage, transport and handling of engine petrol relevant legal regulations must be observed (Act no. 38/91 Coll., Directives of the Czech Ministry of Health, Railway Transport Rules, ČSN 65 0201, ČSN 65 6060 standards and others).
