    摘要: An ECU detects heat generation center of gross heat value. A combustion state of an engine is determined based on the heat generation center. When a deviation between the average heat generation center and the subject heat generation center exceeds a predetermined value, the ECU determines that the engine combustion state is deteriorated. With respect to a cylinder in which the combustion state is deteriorated, fuel injection amount is increased. With respect to a cylinder in which the combustion state is not deteriorated, the fuel injection amount is decreased in order to perform lean-limit control.

    摘要: In a counter circuit of a control signal generating circuit, a selector circuit selects under control which is in accordance with a selector circuit control signal (CTR) a predetermined one in a signal VSYNC and a signal HSYNC, which are pulse signals, so as to input a pulse signal thus selected to a counter. The counter outputs a counted result of pulses of the inputted pulse signal. By use of the counted result, a VSYNC synchronization signal generating circuit or an HSYNC synchronization signal generating circuit generates a control signal to control the driving of image display.
