摘要： The target peak current value where current value is reduced in conformity to the drop of voltage of battery (18) is stored in target peak current storage unit (68). ON-signals are sent from current control circuit (56) to power transistor (50) in response to the injection command pulse coming from engine controller (58) so that current is applied to coil (20). Then the current flowing to coil (20) is detected by the current detecting resistor (52). Comparator (62) compares this detected current and the target peak current value read from the target peak current storage unit (68) conforming to the voltage of battery (18). If agreement is found between these two values, OFF-signals are sent to power transistor (50) from current control circuit (56) in response to the switching command coming from comparator (62). Then the On/Off signals to send holding current to coil (20) are sent from current control circuit (56) to power transistor (50). The linearity of the injection volume despite changes in battery voltage can be maintained.

摘要： The invention relates to an internal combustion engine with direct injection and supercharging in which the ignitability deteriorates because the density of the fuel at the spray center becomes excessive due to the shrinkage of the fuel spray under the supercharging. As a result, the density of the smoke and the hydrocarbon exhaust rate increase. The mixture of the fuel and the air under the supercharging is promoted by the control of a TCV installed in the suction port which is a divided spray and air flow generation mechanism and by the valve timing control of the suction and exhaust valve, etc.
