A method for controlling the electrical power supply of injectors for a hybrid automotive vehicle, including an internal combustion engine and an electric motor. A first electrical network, having a first DC voltage, supplies power to a motor control of the engine. A second electrical network having a second DC voltage, higher than the first DC voltage, supplies power to the electric motor. The method includes connecting the second DC voltage to the injectors; reading the value of the second DC voltage; adapting control parameters of the injectors based on the value of engine speed, engine temperature and injection pressure upstream of the injectors; and controlling the injectors using the second DC voltage. Wherein there is no change in the control parameters when the value is higher than a threshold value; and changing at least one of the control parameters when the value is lower than the threshold value.

In view of the foregoing issues, an object of the present invention is to provide a vehicle control device that reduces the constraints of heat generation and charging time of a booster circuit, and decreases favorably the fuel consumption and exhaust emission of an engine. A vehicle control device installed in a vehicle, the device includes: a battery; a high-voltage battery that has a voltage higher than a voltage of the battery; and a fuel injection device that injects fuel into an internal combustion engine, wherein the vehicle control device includes a control unit that determines whether to supply a drive current to the fuel injection device by the battery or supply a drive current to the fuel injection device by the high-voltage battery, and controls the fuel injection device.

The objective of the invention is to cause a load for reducing the warm-up time of an exhaust gas purifying device to be generated efficiently, and to make effective use of the energy required to reduce the warm-up time of the exhaust gas purifying device. The present invention relates to a vehicular storage battery system used in a vehicle 1 having an exhaust gas purifying device 12 which purifies exhaust gas from an engine 11, the vehicular storage battery system including: a capacitor 14 which stores electric power generated by an electricity generator 13 driven by the engine 11; an electric power control circuit 17 which controls the supply of electric power generated by the electricity generator 13 to a battery 15 and to the capacitor 14; a warm-up control device 18 which determines whether or not the exhaust gas purifying device 12 requires warming up; and a control means which, if the warm-up control device 18 determines that the exhaust gas purifying device 12 requires warming up, controls the electric power control circuit 17, and after the engine 11 has started up, causes the engine 11 to drive the electricity generator 13 and causes the electric power generated by the electricity generator 13 to be supplied more preferentially to the capacitor 14 than to the battery 15.

A system of optimizing carburetor operation comprising: a carburetor controller; an air-fuel ratio sensor; a first communication channel; a processor; a power source; a non-transitory computer-readable memory element; a second communication channel for transmitting and receiving data; an external device; wherein said sensor sample air-fuel ratio in said carburetor; said sensor send said air-fuel ratio information via said first communication channel to said processor; said processor store it in said non-transitory computer-readable memory element; and said processor also send said information to said external device via said second communication channel. A carburetor spacer apparatus with multiple ports is also presented.
