Embodiment Construction

[0032] Hereinafter, an internal combustion engine control device according to an embodiment of the present invention will be described in detail with appropriate reference to the drawings.

[0033] [Structure of internal combustion engine control device]

[0034] First, the configuration of an internal combustion engine control device according to the present embodiment will be described with reference to FIG. 1 . The internal combustion engine control device of the present embodiment is a typical internal combustion engine control device suitable for mounting on an internal combustion engine mounted body such as a general-purpose machine such as a generator or a vehicle such as a motorcycle. However, for convenience of description, the internal combustion engine control device will be referred to as An internal combustion engine control device installed in a vehicle such as a motorcycle will be described.

[0035] Figure 1A is a schematic diagram showing the configuration o...

Abstract

In the engine temperature calculation processing of this internal combustion engine control device (1), a CPU (21) calculates the temperature of an injector (7) while reflecting the ambient temperature of an engine, and controls the operating state of the engine on the basis of the temperature of the injector (7).

Description

technical field [0001] The present invention relates to an internal combustion engine control device, and more particularly to an internal combustion engine control device applied to a general-purpose machine such as a generator or a vehicle such as a motorcycle. Background technique [0002] In recent years, in vehicles such as general-purpose machines such as generators and small motorcycles, it is difficult for the carburetor system to cope with stricter exhaust gas regulations in the future, so fuel injection systems for the purpose of reducing exhaust gas have been promoted. However, since the selling prices of general-purpose machines such as generators and small motorcycles are cheaper than those of large motorcycles and four-wheeled vehicles, when such selling prices are considered, , Compared with carburetor systems, it is difficult to directly apply high-cost fuel injection systems to general-purpose machines such as generators or vehicles such as small motorcycles...
