A method of operating a two-stroke, spark-ignited, internal combustion engine in which the ignition is time-based controlled at low or idle speeds and is crank-angle-based controlled at higher speeds.

Method of operating a fuel injected engine

Disclosed herein is a fuel pump comprising a housing including therein a high pressure fuel chamber, a fuel outlet valve communicating with the high pressure fuel chamber and being operable to prevent fuel inflow and to permit fuel outflow when the fuel pressure is above a predetermined level, a fuel inlet valve communicating with the high pressure chamber and being operable to prevent fuel outflow and to permit fuel inflow, and a bearing bore extending from the high pressure chamber, a rod slideably and sealingly supported in the bearing bore for movement relative to a retracted position, and structure located in the housing for displacing the rod from the retracted position and in the direction toward the high pressure fuel chamber through an initial stroke length without encountering substantial resistance and thereafter displacing the rod through a subsequent stroke length which is effective to highly pressurize the fuel in the high pressure fuel chamber.

Combined pressure surge fuel pump and nozzle assembly

A method of constructing a magnetic flux gap comprising fabricating a first portion from a material having low reluctance and so as to provide an end surface, and a cylindrical inner surface having a diameter, fabricating a second portion from a material having high reluctance and so as to provide axially spaced first and second end surfaces, and a cylindrical inner surface having a diameter greater than the diameter of said cylindrical inner surface of said first portion, fabricating a third portion from a material having low reluctance and so as to provide an end surface, and a cylindrical inner surface having a diameter substantially equal to the diameter of said cylindrical inner surface of said first portion, fixing together the first and second portions with the first end surface of the second portion in axially abutting adjacent relation to the end surface of the first portion and with said cylindrical inner surfaces in concentric relation, fixing together the second and third portions with the second end surface of the second portion in axially abutting adjacent relation to the end surface of the third portion and with said cylindrical inner surfaces in concentric relation, whereby to define a magnetic flux gap radially inwardly of the cylindrical surface of the second portion.
