| University research has produced the oral polio vaccine, the electronic organ, the first antihistamine, and antiknock gasoline. |
|
| Octane rating is a unit of measurement established by the automative industry to determine the antiknock quality of a fuel. |
|
| For many years the business was based almost entirely on the production and sale of the antiknock compound for use in leaded petrol. |
|
| At that time, the main product was ethylene dibromide, an additive in antiknock gasoline compounds. |
|
| Tetraethyl lead has been added to petrol since the 1930s as an effective antiknock and also antiwear additive. |
|
| Specialty fuel additives include deposit control agents, corrosion inhibitors, antioxidants, antiknock agents, metal deactivators and others. |
|
| Tetraethyl lead, added to gasolines for many years to improve antiknock fueling, has been found to contaminate the exhaust gases with poisonous lead oxides, and so the practice has ended. |
|
| In general, gases have better antiknock qualities than gasoline, permitting slightly higher compression ratios without knock or other combustion difficulties. |
|
| These lead compounds have been used in paste mixtures in storage batteries, in cements, glasses, and ceramics, as pigments in paints, and as an antiknock agent in gasoline. |
|
| Enriched fuel with additives like ignition accelerators, antiknock agents. |
|
| Control over combustion quality and improvement in the antiknock properties of petrol engines through the use of oxygenates has become widely accepted practise. |
|
| Antiknock quality is rated by the octane number of the gasoline. |
