Abstract: PURPOSE:To enable improvement of cooking finish through extremely simple control by a method wherein solely by setting a kind of a container or the presence of a substance adhered to an upper surface opening by means of a setting means, a heating condition is automatically corrected by a correcting means according to a set content. CONSTITUTION:Only a cooling fan 11 is run during t1 seconds starting from the starting of cooking to ventilate the interior of a heating chamber 2. A food to be cooked is heated by means of microwaves generated by a magnetron 10. By means of a ventilating effected produced through running of the cooling fan 11, the output voltage of a gas sensor 8 is increased in succession. With the increase in gas concentration in the heating chamber 2, the output voltage of the gas sensor 8 is reduced, A maximum value Vmax of the output voltage of the gas sensor 8 is stored in a control part 27, and by multiplying the maximum value Vmax by a constant alpha, alphaVmax is calculated. A point of time t2 when, the output voltage of the gas sensor 8 is decreased from Vmax by alphaVmax is detected to calculate a heating time T=t2-t1. By multiplying the heating time T by a constant beta, an additional heating time betaT is calculated, and at a point of time when a time betaT lapses starting from the time t2, cooking is completed. In this case, by changing the constant beta according to a set content, a heating condition is corrected.

IPC: F02D41/32
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To ensure necessary fuel injection amount while minimalizing a pump capacity of a high pressure fuel system for injecting fuel into a cylinder. SOLUTION: When a fuel pressure of a high pressure fuel system becomes a pressure determination threshold value or less, increase or decrease amount ΔG of a request fuel injection amount is calculated (S120), all of the increase and decrease amounts ΔG is allocated to an amount Go of fuel injection outside the cylinder to set a pulse width Tio of fuel injection outside the cylinder (S121, S122), and cylinder fuel injection and a intake pipe fuel injection outside the cylinder are used in common.  The pulse width Tio of fuel injection outside the cylinder is shortened in accordance with the decrease of the request fuel injection amount, and when the fuel pressure of the high pressure fuel system is recovered to increase more than a third pressure determination threshold value, the pulse width Tio of fuel injection outside the cylinder is decreased and is shifted to a state in which only the cylinder fuel injection is carried out. Accordingly, an amount of a cylinder fuel injection amount is maintained to be approximate constant regardless of the increase or decrease of the request fuel injection amount thereby stabilizing a cylinder injection pressure, an atomization form into the cylinder is made constant to uniformize combustion, whereby drivability is improved.
