Abstract
Abstract The invention is provided with a load detecting means for detecting the value of an electric load connected to an electric generator driven by an internal combustion engine. An idling speed-up means stepwise increases an idling speed of the engine. A control means causes the idling speed-up means to operate when the detected value of the electric load continuously remains above a predetermined value for a predetermined length of waiting time. The control means is provided with a variable setting means which variably sets the waiting time in such a manner that the larger the detected value of the electric load, the shorter the length of the waiting time.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
An idling speed-up control apparatus in an internal combustion engine comprising: an electric generator driven by the internal combustion engine; a load detecting means for detecting the value of an electric load connected to the electric generator; an idling speed-up means for stepwise increasing an idling speed of the engine; and a control means for causing the idling speed-up means to operate when detecting value of the electric load continuously remains above a predetermined value for a predetermined length of waiting time, the control means includes a variable setting means for variably setting the waiting time such that the larger the detected value of the electric load, the shorter the length of the waiting time.
Claim 2
Dependent Claim
115 words
An idling speed-up control apparatus in an internal combustion engine comprising: an electric generator driven by the internal combustion engine; a load detecting means for detecting the value of an electric load connected to the electric generator; an idling speed-up means for stepwise increasing an idling speed of the engine; and a control means for causing the idling speed-up means to operate when detecting value of the electric load continuously remains above a predetermined value for a predetermined length of waiting time, the control means includes a variable setting means for variably setting the waiting time such that the larger the detected value of the electric load, the shorter the length of the waiting time.
Claim 3
Dependent Claim
37 words
An idling speed-up control apparatus as claimed in claim 1, wherein the variable setting means is constructed so that the length of waiting time is stepwise varied in accordance with the detected value of the electric load.
Claim 4
Dependent Claim
37 words
An idling speed-up control apparatus as claimed in claim 1, wherein the variable setting means is constructed so that the length of waiting time is continuously varied in accordance with the detected value of the electric load.
Claim 5
Dependent Claim
53 words
An idling speed-up control apparatus as claimed in any one of claims 1, 2, or 3, wherein the control means is constructed so that the variable setting means causes the idling speed-up means to operate, regardless of the value of the electric load, when an engine temperature is below a predetermined set temperature.
