Claims

[Scope of utility model registration request]

Throttle valve drive control means for changing the opening degree of a throttle valve arranged in an intake passage of the engine according to the amount of operation of an accelerator operation part provided for the engine; a remaining fuel amount detecting means for detecting the remaining amount of fuel; and when the remaining amount of fuel detected by the remaining fuel amount detecting means is below a predetermined value, the throttle valve drive control means is configured to respond to the amount of operation of the accelerator operating section. 1. A throttle valve control device for an engine, comprising a throttle opening correction means for reducing the opening of a throttle valve.
