Systems and methods for starting and restarting an engine of a vehicle are disclosed. Power systems for an engine are disclosed.

An equipment stabilizer for a pull cord start that secures a piece of equipment, such as a chain saw, to a base plate via lockable jig clamps and assists in pulling the pull cord start by providing a pulley operated by a foot pedal. Ratchet straps pass through a horizontal slot through the base plate. An upright beam on the base plate front side has vertically aligned apertures proximal an upper side thereof for spring tension adjustment. A pulley operationally connects a pedal member of the foot pedal to a handle of the pull cord start. Pressing on the pedal member while holding onto the vertical beam moves the pull cord start handle toward the wheel end to start a motor of the piece of equipment.

The internal combustion engine ignition device has a core, a coil part that is wound over the core, and a secondary coil that is wound on the outer peripheral side of the coil part. A switching element switches an induced current, which is generated via the rotation of a permanent magnet, of a primary coil on and off. A resistor and a microcomputer are connected to the switching element, and a rotation detection circuit is connected to the microcomputer. The microcomputer drives the switching element so as to rapidly change the current flowing through the primary coil and generate a high voltage in the secondary coil, and generate a spark discharge in a spark plug connected to the secondary coil. In the coil part, one coil is divided by an intermediate tap, forming the primary coil and a charging coil.

An electric turning machine (ETM) operatively connected to an internal combustion engine (ICE) is operated as a motor with a first control strategy and as a generator with a second control strategy. In the first control strategy, electric power is delivered from a power source to the ETM selectively through at least one transistor of an electrical converter. After switching from the first control strategy to the second control strategy, the ETM delivers electric power to an accessory selectively through the at least one transistor of the electrical converter.

A method and a system for operating an electric turning machine (ETM) operatively connected to an internal combustion engine (ICE) are disclosed. The ETM operates as a motor with a first control strategy and as a generator with a second control strategy, the second control strategy being distinct from the first control strategy. The system comprises an engine control unit adapted for controlling an operation of the ETM according to the first and second control strategies. Electric and assisted start procedures are available for starting the ICE by delivering electric power from a power source to the ETM which is co-axially mounted to a crankshaft of the ICE. Assisted start includes delivering the electric power to the ETM while a recoil starter is used to rotate the crankshaft. A manual start procedure is also available. The power source is charged by the ETM when the ICE is running.

A method for operating an electric turning machine (ETM) operatively connected to an internal combustion engine (ICE) are disclosed. An engine control unit (ECU) controls the ETM to operate as a motor with a first control strategy and as a generator with a second control strategy. The second control strategy is distinct from the first control strategy. The ECU controls switching the operation of the ETM from the first control strategy to the second control strategy when a sensor senses that a rotational speed of the ICE is equal to or above a minimum revolution threshold.
