Disclosed herein is a method for increasing the maximum operating speed of an internal combustion engine operated in a low temperature combustion ignition mode, the method comprising operating the engine with a fuel composition comprising (a) gasoline having a Research Octane Number (RON) greater than 85 and (b) one or more cetane improvers.
Abstract:
A method of introducing additives to an air intake system of an engine in order to overcome one or more of the various problems created by formulation of additives in fuels. The method controls at least one of the amount, aerosol particle size and timing of introduction of additives based on information relevant to operation of the engine. The introduced additives form an air-additive mixture and are carried by the airflow in the air-intake system to the combustion chamber of the engine. Another aspect of the invention is an additive introduction system that includes one or more containers for additives, a control system for determining at least one of the amount, aerosol particle size and timing of introduction of the additives, and a device to introduce the additives into the air intake system under the control of the control system.

Abstract:
A method of Improving the efficiency of a diesel engine provided with a source of diesel fuel includes the steps of: a) adding to the diesel fuel a reverse-micellar composition having an aqueous first disperse phase that includes a free radical initiator and a first continuous phase that includes a first hydrocarbon liquid, a first surfactant, and optionally a co-surfactant, thereby producing a modified diesel fuel; and b) operating the engine, thereby combusting the modified diesel fuel. The efficiency of a diesel engine provided with a source of diesel fuel and a source of lubricating oil can also be improved by modifying the lubricating oil by the addition of a stabilized nanoparticulate composition of cerium dioxide. The efficiency of a diesel engine can also be improved by adding to the diesel fuel a reverse-micellar composition that includes an aqueous disperse phase containing boric acid or a borate salt.
