Title:
OIL FEEDER FOR TWO-CYCLE ENGINE WITH AUTOMATIC TRANSMISSION GEAR FOR VEHICLE
Document Type and Number:
Japanese Patent JP3368778
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent seizure of an engine in case of quick acceleration by computing an engine speed increase rate, and performing quick acceleration time oil supply control for operating a discharge restraining means so as to switch the real discharge to the basic discharge in case of the computed value being not less than the set value showing rapid acceleration of a vehicle.
SOLUTION: In case of accelerating a scooter type vehicle rapidly, engine speed increases rapidly due to the kick-down action of an automatic transmission gear. At this time, when the engine speed reaches engine speed short of the shift rotating speed of the automatic transmission gear, an engine speed increase rate is computed by a minicomputer 12 from the engine speed increase quantity per unit time. The computed value is compared with the set value showing rapid acceleration. In case of the computed value being not less than the set value showing rapid acceleration, a solenoid 8 is operated off. The discharge of an oil pump 7 is thereby switched to the basic discharge that is the maximum oil quantity demanded at the time of full admission acceleration, so as to ensure sufficient oil supply to a two-cycle engine 1.
