Class Information
Number: 123/403
Name: Internal-combustion engines > Engine speed regulator > Charge volume varying (e.g., total amount of mixture fed to engine is varied; relative amounts of air and fuel are fixed) > Throttling (e.g., volume varying using throttle valve)
Description: Subject matter in which the flow of fuel, oxidant, or combustible mixture to the engine or mixing chamber is controlled by varying the cross-sectional area of the mixture conduit or of the conduits of the components of the mixture, thereby varying the volume of charge for induction into the engine cylinder.
