A vehicle includes an engine and a controller. The controller may be configured to, responsive to indication of a temperature of a starter-generator exceeding a de-rated threshold, command the engine to start and disable engine automatic shut-off. And the controller may be configured to, responsive to indication of the temperature exceeding a disabled threshold, or the temperature exceeding the de-rated threshold and a traction battery discharge power being less than a threshold, command the engine to start and shed a load.

An electric starting system for an internal combustion engine is provided. The starting system includes a rechargeable battery, a battery receiver, and a starter motor. The rechargeable battery including a battery housing, internal circuitry housed within the battery housing, two voltage output terminals, and an enable terminal. The battery receiver includes a battery receptacle configured to receive the rechargeable battery, two voltage output terminals, and the enable terminal. The starter motor is configured to start the internal combustion engine. The internal circuitry is coupled to the enable terminal and configured to enable and disable an internal switch to provide power to one of the two voltage output terminals, the internal circuitry monitoring at least one internal condition of the rechargeable battery for a fault condition. The internal circuitry disables the internal switch upon detection of the fault condition.

A system for preventing an engine included in a work machine from restarting, after the work machine is tipped over. A sensor included in the work machine is configured to detect a tipping incident. If a tipping incident is detected, the sensor sends out a signal configured to shut down the engine and a tilt signal configured to prevent the engine from restarting. The engine is only restarted if certain steps are undertaken by an operator and a reset switch is activated.

A method of controlling a safety apparatus of a construction machine includes: applying a power to the construction machine when a key switch operation of a worker is input; receiving operation signals of the parking switch, the FNR switch, and the pilot cutoff switch; determining whether operation states of the parking switch, the FNR switch, and the pilot cutoff switch satisfy predetermined conditions; and controlling the construction machine to be available for the start-up when the predetermined conditions are satisfied. The predetermined conditions are that the parking switch is operated to be on so that a parking brake is operated, the FNR switch is operated to select a neutral so that a traveling direction of the construction machine is in a neutral state, and the pilot cutoff switch is operated to be on so that the construction machine is in a pilot cutoff state.

Systems and methods for operating an engine that may be rotated by an electric machine during engine starting are described. In one example, an amount of electric current that is available to rotate the engine via the electric machine may be adjusted in response to an indication that a vehicle that includes the engine may be parked in a geographical area that may be flooded.

A snowmobile includes a frame with a tunnel, a fuel tank disposed thereon and an engine connected thereto. A throttle body fluidly communicates with the engine. A throttle valve is disposed in the throttle body for regulating fluid flow through the throttle body into the engine, a position of the throttle valve being movable between an open position and a closed position. A throttle operator connected to the frame to control the position of throttle valve is moveable between an idle position and a drive position. A throttle valve actuator operatively connected to the throttle valve and the throttle operator controls a position of the throttle valve based at least in part on the throttle operator position, the throttle valve actuator being an electric throttle valve actuator and disposed longitudinally between the fuel tank and the engine. Vehicles and methods of operating the vehicles are also disclosed.

An electronic start system for an agricultural machine is configured to enable the machine to stop the engine while continuing to power onboard electronics and start the engine so long as one or more sensed conditions are met. The system can include a key lock operated by a physical key held by an operator and a button which can be pressed by the operator. The system can also include one or more sensors disposed on the machine for detecting various conditions. When the key is turned on, power can be provided to the onboard electronics, regardless of the state of the engine. Thereafter, when the button is pressed, the engine can be turned on if the one or more sensed conditions are satisfied, such as detecting a closed door, an operator in a seat, an activated brake, and so forth.

An electronic control device includes a first pull-up resistor connected between a power supply and a switch, a series circuit of a transistor and a second pull-up resistor with a resistance value lower than that of the first pull-up resistor, connected in parallel with the first pull-up resistor, and a microcomputer, an output port of which is connected to a base terminal of the transistor and which controls a turning on and off of the transistor using a signal output from the output port. A connection point of the switch, the first pull-up resistor, and the second pull-up resistor is connected to a first analog measurement port of the microcomputer, a power supply is connected to a second analog measurement port of the microcomputer, and current flowing into the switch is detected using a value of voltage input into the first analog measurement port.

A carbon monoxide detector and control system for internal combustion engine or heating devices and a method of operating the carbon monoxide detector system.

Disclosed is an electric starter with a manual turning function. A main shaft, a drive gear mechanism, a shift fork, an electromagnetic relay guide rod and a first return spring are arranged in a housing of the electric starter. A gear shifting mechanism comprises a force receiving component which extends out of the housing of the electric starter and serves as an external force applying point so as to promote the electromagnetic relay guide rod to move rightwards, a normally closed switch for cutting off a power supply of the electric starter when the force receiving component moves to an extreme position, a positioning component for locking the force receiving component when the force receiving component moves to the extreme position, and a first return component which enables the force receiving component to automatically returns to an original state when the force receiving component is unlocked. The main shaft is indirectly driven to rotate by the turning mechanism via a transmission mechanism or directly driven to rotate by the turning mechanism via a turning tool. An improvement is made to a structure of a traditional electric starter without affecting existing functions thereof, i.e., a function of manual turning is added. Therefore, a flywheel gear of a motor can be precisely positioned during maintenance so as to improve efficiency and eliminate potential safety hazards.
