Manual-control driving and sensing precision fine-tuning intelligent oil feeder

Abstract

The invention discloses a manual-control driving and sensing precision fine-tuning intelligent oil feeder comprising an oil feeder body, an oil-inlet oil needle lift mechanism and a throttle valve opening mechanism, wherein the oil-inlet oil needle lift mechanism is arranged on the oil feeder body and comprises an oil needle lift position sensor; and the throttle valve opening mechanism comprises a throttle valve opening position sensor and an ECU (Electronic Control Unit). The invention combines the oil-inlet oil needle lift mechanism with the throttle valve opening mechanism; the ECU controls throttle valve opening according to a lift position signal of the oil-inlet oil needle lift mechanism and other motor vehicle driving parameter signals and verifies and detects whether the throttle valve opening is a needed opening or not by using a position sensor signal of the throttle valve opening mechanism so as to prevent signal disorder, step losing and uncontrollability, therefore the optimal matching and the control of the throttle valve opening and oil needle lift are achieved; thus a flammable mixed gas needed by theoretical air-fuel ratio is achieved, and then the optimal matching and the control of the engine power target (load and rotating speed), the oil needle lift, the throttle valve opening and the gear are realized.

Description

technical field [0001] The invention relates to a component of an engine fuel supply system, in particular to a manual transmission sensor fine-tuning intelligent fuel supply device. Background technique [0002] The engine is the power source of a motor vehicle, and its operating status is directly related to the driving performance of the motor vehicle, and has a decisive impact on various economic indicators of the motor vehicle, including cost and environmental protection performance. Proper fuel supply, air supply and air-fuel ratio when the engine is working are one of the most important indicators of the engine, which determine whether the vehicle's power performance, fuel economy performance, and emissions meet environmental protection requirements. [0003] Ideal air-fuel ratio for engine combustion: The complete combustion of 1g of gasoline theoretically requires 14.7g of air. The air-fuel ratio is different under different working conditions, such as: [0004] 1...

AI Technical Summary

Problems solved by technology

[0013] 1. Since there is no oil needle lift sensor and throttle opening sensor, it cannot automatically detect the change of fuel supply caused by the change of oil needle lift, and cannot automatically detect the change of steam supply caused by the throttle opening. Therefore, The electronic control unit cannot match, correct and adjust the air-fuel ratio in real time according to the change of fuel supply, so as to achieve the best match of throttle opening, speed, torque and engine gear, resulting in unstable engine operation;

[0014] 2. The adjustment range of the intake air volume is limited, and the adjustment range of the air-fuel ratio is narrow;

The operation of human control (manual or foot) depends entirely on the driver's subjectivity. Because there is no automatic detection, correction and elimination of the driver's operation errors, it is impossible to achieve the optimum throttle opening, speed, torque and engine gear. When the vehicle speed changes suddenly, the abnormal air-fuel ratio will cause the engine to run in an unsteady state, which will inevitably make it difficult to match the engine power and driving resistance, resulting in unstable engine operation; at the same time, the motor vehicle is driven by the driver. In the case of not knowing the driving resistance, the transmission device controlled only based on experience will often force the engine speed to drop and work in the low-efficiency area due to the increase of driving resistance when starting, uphill and heavy load, and the driver often overdrives. Large fuel supply to prevent the engine from "flashing", but the air-fuel ratio control is not ideal, which increases fuel consumption and emissions
