Problems solved by technology
[0006] Also, a related technology similar to the above-mentioned technology has been proposed, but there is still a problem of deviation due to the inaccuracy of the method for determining the injection amount used as a reference, and the output is lowered.
[0007] Also, there is a problem that it is impossible to prevent the crash caused by the problem of the electronic control unit of the car
[0008] And, in the case of rapid acceleration, it is more important to increase the output in the shortest time than the control to solve the output deviation between the cylinders, but there is a problem that it does not have this function

Embodiment 1
[0078] After setting the automotive fuel control injection device of the present invention in the SM520 automatic vehicle produced in 2002, the fuel consumption was measured by driving, and under the same conditions, the fuel consumption was measured in the state where the device of the present invention was not installed, and carried out Compare.
[0079] Table 1
[0080]
[0081] In the experiment as mentioned above, compared with the vehicle not provided with the device, the gasoline (fuel) consumption of the vehicle provided with the fuel injector injection volume control switch of the present invention was reduced by 7.27%. 25.03% of gasoline (fuel) consumption can be saved for vehicles with injection quantity control card off and air intake valve opener.

The invention provides a control device for automotive fuel injection including a throttle value input part; a signal input part of an electronic control unit receiving a signal form the electronic control unit for sending to an oil atomizer of each air cylinder; a brake signal input part for receiving a signal form a brake; a plurality of output control switches of oil atomizers for controlling the oil atomizers wherein the switches are positioned between oil atomizer coils of air cylinders and power supply; and a control unit calculating in a specified manner and outputting a control signal to a plurality of output control switches of oil atomizers to control a plurality of oil atomizers based on the received signals from the throttle value input part, the signal input part of the electronic control unit and the brake signal input part. The control device for automotive fuel injection can reduce the noise and the vibration by reducing the output deviation among different air cylinders, improve the automotive fuel economy, and prevent bursting caused by the automotive electronic control unit.
Description
technical field [0001] The present invention relates to a fuel injection control device for an automobile engine, and more specifically relates to distributing and supplying different amounts of fuel to each cylinder of the engine according to changes in the engine speed in the engine, thereby not only preventing deviations caused by the engine speed The noise and vibration caused by it can reduce fuel consumption. When the control device breaks down, it is used to be directly connected to the electronic control unit (Electronic Control Unit: ECU). When accelerating rapidly, it does not need the fuel injection control of the present invention and directly injects fuel through the electronic control unit. In the case of UA), the fuel injection control device that cuts off the fuel. Background technique [0002] Normally, the engine adjusts the load by adding or subtracting fuel delivery. [0003] At this time, the engine is composed of a plurality of cylinders, and each cyl...
