On the other hand, (during Te＜Teh), above (Td 〉=Tdh), then total calculating augmenting factor is Ke (Kd=1) (top left region among Fig. 7) if difference Td reaches set point of temperature difference Tdh less than set point of temperature Teh as oil temperature Te.
In addition, at difference Td in that ((in the zone of Te 〉=Teh), total calculating augmenting factor is Kd (Ke=1) (lower right area among Fig. 7) more than set point of temperature Teh for Td＜Tdh) and oily temperature Te below the set point of temperature difference Tdh.
During common fuel injection control after the revisal of warming-up increment finishes, the product Kd * Ke of calculating augmenting factor becomes 1 (Kd=Ke=1) (right regions among Fig. 7).
Like this, adopt above-mentioned mode of execution, in the fuel injection compensating device 30 when being furnished with the warming-up of the air-cooled internal combustion engine that fuel is sprayed the electronic control fuel injection device 32 that carries out electrical control, be furnished with the intake air temperature sensor 34 that detects intake temperature Ti, oil temperature sensor 36 and the control gear 40 that detects oily temperature Te.This control gear 40 is controlled sparger 38 to detect low more and poor Td (Td=Te-Ti) mode more little, that then fuel injection amount is many more that detect oily temperature Te and detect intake temperature Ti of oily temperature Te.
Since not only with respect to the oily temperature Te that is considered as engine temperature, also with respect to intake temperature Ti, carry out the revisal of warming-up increment and handle, so can control more reliably.
In this case, utilize oily temperature compensation positive coefficient chart 42 and oily temperature intake temperature difference augmenting factor chart 44, can be simply and promptly obtain warming-up increment revisal amount.
In addition, the invention is not restricted to above-mentioned mode of execution,, can take various structures according to the content that this specification is put down in writing.
As explained above such, adopt the present invention, can grasp the engine temperature of air-cooled internal combustion engine reliably, and can take intake temperature into account and carry out warming-up increment revisal processing by the detection of oil temperature, thereby, can carry out the judgement of reliable warming-up concluding time.
