In a system for controlling rotation of torque applied to a rotating shaft of an engine of a vehicle that uses the engine as a drive source thereof, a motor is provided. A main controller controls the engine and the motor. The main controller selectably activates the motor that applies first torque to the rotating shaft of the engine, and deactivates the motor. A rotary electric machine includes a rotor connected to the rotating shaft of the engine. A rotation parameter detector measures a rotation parameter associated with rotation of the rotor of the rotary electric machine. A sequence controller performs, in response to an occurrence of a trigger situation, a control sequence that controls, independently of the main controller, the rotary electric machine based on the rotation parameter measured by the rotation parameter detector, thus applying second torque to the rotating shaft of the engine.

A filter monitoring system and method are described. The filter monitoring system includes a remote telematics system, and a data link between the remote telematics system and an onboard telematics system. The remote telematics system is configured to receive, via the data link, an indication of a pressure drop across a filter cartridge of the filtration system from the onboard telematics system, determine a first value indicative of a remaining filter life of the filter cartridge of the filtration system, determine a second value indicative of a remaining filter life of the filter cartridge that is determined in a different manner than the first value, compare the first value to the second value to determine which value indicates a least amount of life remaining for the filter cartridge, and transmit an indication of the least amount of life remaining for the filter cartridge based on the comparison.

This present disclosure discloses an ignition overcurrent protection device, which includes a switch, a current detection circuit, and a controller. The switch is electrically coupled between a starting power and a power-on connector; the power-on connector is configured for connecting to the automotive power. The current detection circuit is configured for detecting a current value flowing between the starting power and the power-on connector. The controller is coupled to the switch and the current detection circuit. The controller is configured to determine a current range where the current value is located, and determine a preset time threshold corresponding to the current range, and control the switch to be turned off when a duration of the current value reaches the preset time threshold. The present disclosure also provides a starting power equipment and ignition overcurrent protection.

In a method and a device for operating an internal combustion engine, with at least one cylinder (Z1-Z4) having a combustion chamber (26), fuel is injected into the cylinder and a logic value (LV_FCUT) is set, in particular for stopping the injection of fuel into the cylinder, The method furthermore has the following steps: depending on a course of the highly time-resolved measurement signal of a rotational speed (N_FAST) of the internal combustion engine, a local maximum value (N_FAST_MAX) of the rotational speed is determined, a rotational speed difference (N_FAST_DIF) between the local maximum value (N_FAST_MAX) and a current measured value (N_FAST_MES) of the rotational speed is determined, and, depending on the determined rotational speed difference (N_FAST_DIF), the logic value (LV_FCUT) is set.

A protection device for preventing automobile engines from abnormal starts comprises automobile batteries (10), a start motor (20) and a control circuit (30) disposed therebetween. The control circuit (30) comprises a main control unit MCU1, a start switch (31), a start relay (321) and a power supply relay (322), the coil of the start relay (321) being connected to the automobile batteries (10) through the normally closed contact of the power supply relay (322). The start relay in the present invention is connected to the batteries rather than directly but through the normally closed contact of the power supply relay. In addition to being controlled by the main control unit, the start relay is also controlled by the power supply relay, thereby providing additional insurance and more effective protection so as to avoid the damage of the start motor due to erroneous actions.

In an apparatus for detecting tip-over of a rammer equipped with a crankcase accommodating an output shaft rotatably connected to an engine, a movable unit accommodating a converter mechanism for converting rotation of the output shaft to vertical motion of a movable member, a tamping shoe connected to the movable unit, and a handle operable by an user, and adapted to thrust upward in the gravitational direction by the vertical motion of the movable member and go into a free fall to compact a ground surface, it is determined whether a detected engine speed becomes equal to or smaller than a threshold value set lower than an engine idling speed when the engine has been operated at a rammer working speed set greater than the engine idling speed, and if it does, it is discriminated that the rammer has tipped over.
