An engine is equipped with a starter motor which is attached to an engine main body and is configured to perform cranking of a crankshaft. The engine is further equipped with a battery pack (). The battery pack is equipped with a lithium-based cell which is attached to the engine main body and which is configured to supply electric power which drives the starter motor.

Engine, self-starter unit, and method for altering engine specifications

A notification acquiring section receives, from a device, a notification message indicating at least one of an aggregate value of data communication amounts obtained by aggregating, per unit of aggregation time of one second or longer, the data communication amounts of the device which have been measured on a millisecond or microsecond basis; and an aggregate value of data accumulation amounts obtained by aggregating, per unit of the aggregation time, the data accumulation amounts in the device which have been measured on the millisecond or microsecond basis. A determining section analyzes at least one of the aggregate values of the data communication amounts and the data accumulation amounts indicated by the notification message to determine whether or not microburst traffic has occurred at the device.

Information processing apparatus, information processing method, and computer readable medium

Providing an engine speed control device and an engine speed control method, wherein the no-load condition of the farm working machine can be estimated independently of the farm working machine and a no-loading operation condition of the engine can be automatically shifted to an idling condition. An engine speed control device with which the engine drives a farm working machine, the engine speed control device provided with: a memory sectionin which the throttle opening threshold levels corresponding to the target engine speeds are memorized; a first judgment device that reads out the throttle opening threshold level corresponding to the target engine speed from the memory device, and judges whether or not the current throttle opening threshold level is smaller than or equal to the throttle opening threshold level corresponding to the target engine speed; a target engine speed determining sectionby which the target engine speed diminishes to a low idling engine speed in a case where the first judgment device judges that the current throttle opening threshold level is smaller than or equal to the throttle opening threshold level corresponding to the target engine speed; and, a throttle opening regulating devicethat regulates the opening of the throttle valve based on the target engine speed.

Engine speed control device and engine speed control method

It is intended to provide an air-fuel ratio control device for a carburetor, which is capable of variably inject fuel by opening and closing a choke valve in accordance with an opening degree of a throttle valve and the load and which is capable of achieving low cost, clean emission and fuel saving by attaining a desired air-fuel ratio in an entire operational range (rotation speed, load) of the internal combustion engine. The air-fuel ratio control device is provided with, but not limited to, a choke valvearranged in an intake path of an internal combustion engine, a throttle valvearranged in the intake path on a downstream side of the choke valve, a first stepper motordriving the choke valveto adjust an opening degree of the choke valve, a second stepper motordriving the throttle valveto adjust an opening degree of the throttle valve, and a controllercontrolling the opening degree of the choke valvein accordance with a change of a rotation speed of the internal combustion enginebased on the opening degree of the throttle valve, and, when the rotation speed of the internal combustion engineis constant, controls the opening degree of the choke valvebased on a map which determines the opening degree of the choke valvefrom load of the internal combustion engine, so as to achieve a desired air-fuel ratio.
