The Application of TML as an Antiknock Additive in European Cars

Methods of identifying cars responsive to TML, and the connection between a car’s response to TML and its severity are examined. Fuel segregation in the inlet manifold is studied with the object of improving laboratory bench procedures. Laboratory results are supported by customer reaction trials, the techniques of which are fully described. The optimum scavenger combination for use with TML is shown to be 1.0 T ethylene dibromide plus 0.2 T tritolyl phosphate.
