    摘要: In a combustion control device for an internal combustion engine provided with a plurality of fuel injection modes having different target air-fuel ratios, threshold values for detecting deterioration of combustion in the internal combustion engine are determined separately for each fuel injection mode depending on features of variation of combustion in the internal combustion engine in each fuel injection mode. Quantity of variation of combustion in the internal combustion engine is, for example, detected in the form of revolution angular acceleration or revolution angular acceleration deviation of the engine. The detected quantity of revolution fluctuation is compared with a threshold value in the currently chosen fuel injection mode. Thus, deterioration of combustion is surely judged according to each fuel injection mode. In particular, threshold values in a compression stroke injection mode are determined to be larger than threshold values in an intake stroke injection mode. A threshold value in the compression stroke injection mode is so determined as to substantively correspond to a complete misfire state of the engine, and threshold values in the intake stroke injection mode consist of a first threshold value substantively corresponding to a complete misfire state of the engine and a second threshold value substantively corresponding to an unstable combustion state of the engine.

    摘要: A continuous melting apparatus for a low melting point metal is disclosed. The apparatus includes a melting furnace main body (5) forming a combustion chamber (6) surrounded by a refractory lining, a crucible (1) formed with a tapping orifice (2) at an appropriate position of a body and housed at the center portion of said combustion chamber, a burner (8) provided on a side wall portion of said melting furnace main body (5) for heating said crucible (1) in said combustion chamber (6) and a receptacle (6, 13) for receiving a melt flowing out through said tapping orifice (2) of said crucible (1). In the continuous melting apparatus, with employing a melting method of burner heating type which is inexpensive, easy to handle and maintenance, with successfully minimizing oxidation loss which was the shortcoming of the burner type. Also, generation of corundum on the furnace wall surface due to reaction of the aluminum melt and the furnace wall can be successfully avoided.
