Abstract:
A device (100) of controlling crankshaft position of an engine (1000) and an engine (1000) including the device (100) are provided. The device (100) includes: a flywheel (1) adapted to be mounted on a crankshaft (900) of the engine (1000) and having a fitting groove (10) formed in an outer peripheral wall of the flywheel (1);a swinging arm (2) defining a first end (201) adapted to pivotally connect to a body (200) of the engine (1000) and a second end (202) having a fitting tooth (20), and the swinging arm (2) can swing around the first end between an engaging position and a disengaging position; and an actuating assembly (3) connected to the swinging arm (2) to drive the swinging arm (2) to swing.
Abstract:
An energy-saving method and system (402) are provided. The energy-saving method includes: detecting a working condition of a motor (301) in the vehicle (401); detecting a fuel injection quantity of the motor (301), a generating current of a generator (302) in the vehicle (401) and an electric quantity of a battery (305) in the vehicle (401) when the motor (301) is working; determining whether the generating current of the generator (302) is less than a first current threshold when the fuel injection quantity is zero; determining whether the electric quantity is less than a first electric quantity threshold when the generating current is less than the first current threshold; controlling the generator (302) to charge the battery (305) when the electric quantity of the battery (305) is less than the first electric quantity threshold; and controlling the generator (302) to reduce the generating current when the electric quantity of the battery (305) is greater than or equal to the first electric quantity threshold.
Abstract:
A fuel supply system (1000) and a fuel supply control method for an engine (60) of a vehicle are provided. The fuel supply system (1000) includes: a first detecting unit (10) configured to detect an operating state of the vehicle to generate an operating state signal; an engine control unit (20) connected with the first detecting unit (10) and configured to obtain an opening degree of a throttle valve according to the operating state signal, to obtain a current fuel demand according to the opening degree, and to generate a fuel demand control signal based on the current fuel demand; a fuel pump (30) configured to supply fuel to the engine (60); a fuel pump motor (40) configured to drive the fuel pump (30); and a fuel pump motor control unit (50) connected with the fuel pump motor (40) and the engine control unit (20) respectively and configured to control the fuel pump motor (40) according to the fuel demand control signal.
