Abstract
The utility model discloses an electronic fuel injection (EFI) zonal lean-burn electric control fuel economizer, which comprises an automobile engine electronic control unit (ECU), engine sensors, and a microprocessor unit (MPU) connected with the engine sensors, wherein the MPU is connected with the automobile engine ECU through a digital-to-analog converter connected with the output of the MPU. The utility model has the advantages that engine sensor data optimizing and processing devices are connected between the automobile engine ECU and the engine sensors to directly input optimized data to the automobile engine ECU, so that the automobile engine ECU can rematch the air-fuel ratio according to the data provided by the data optimizing and processing devices, thereby realizing the lean burn of engine fuel for fuel conversation, and reducing the fuel emission; the fuel economizer with simple structure has no influence on the structure of an original automobile engine ECU; the installation is convenient and the operation is simple; and an original electric control system can be restored by a user operating a toggle switch.
Description
Technical field
The utility model belongs to automotive controls, is specifically related to a kind of EFI formula subregion lean combustion electric control fuel economizer.
Background technique
Existing automobile fuel-economizing device has the various ways structure.As by electric controller motor being carried out tonifying Qi, this need increase making-up air device, also needs to increase controller ECU simultaneously, and the structural modification increasing to vehicle increases reforming cost.And after vehicle produced, its automotive engine control ECU had cured, and can not carry out the modification of parameter.If desired to the motor flow transducer, data such as motor lambda sensor and engine rotation speed sensor are optimized, to improve the control output of automotive engine control ECU, to reach the effect of fuel-economizing, then need automotive engine control ECU is transformed, work two is big like this, the cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of former automotive engine control ECU of vehicle that do not change, to realize the fuel economizer of the automatically controlled fuel-economizing of EFI formula subregion lean combustion.
The technical solution of the utility model is: EFI formula subregion lean combustion electric control fuel economizer, it comprises automotive engine control ECU, engine sensor, it also comprises with engine sensor and is connected microprocessor MPU, the output of microprocessor MPU connects the D/A converter, connects the D/A converter and connects automotive engine control ECU.
The utility model is by being connected the data-optimized treatment device of engine sensor drawing together between automotive engine control ECU and the engine sensor, the data of optimizing are directly inputted to automotive engine control ECU, the data that make it to provide by data-optimized treatment device are mated air fuel ratio again, make engine fuel realize that lean combustion reaches the fuel-economizing purpose, discharging simultaneously is reduced.It is simple in structure, does not influence the structure of former automotive engine control ECU.Easy for installation, simple to operate, the user is if will recover former car, and only need stirring, toggle switch can recover former car automatical control system
Description of drawings
Fig. 1 EFI formula subregion lean combustion electric control fuel economizer structural representation.
Embodiment
As shown in Figure 1, engine sensor comprises motor flow transducer 1, motor lambda sensor 2 and engine rotation speed sensor 3, they be connected microprocessor MPU 4 and connect, connection mode/number converter 5 between motor flow transducer 1 and the microprocessor MPU 4 wherein, the data that sensor is taked are sent into microprocessor MPU, microprocessor is judged engine operation condition according to the various service datas of motor of gathering, consult the MAP figure that is pre-stored in microprocessor according to each operating mode, draw corresponding optimization data, these data are by after handling, send into ECU through D/A converter 6, make the fuel injection quantity of ECU minimizing motor under equal operating mode, under the situation that does not influence engine output, reach the saving oil consumption, reduced the purpose of discharging.
