Electronic control wheel type driving and sensing precision fine-tuning intelligent oil feeder

Abstract

The invention discloses an electronic control wheel type driving and sensing precision fine-tuning intelligent oil feeder comprising an oil feeder body, a throttle valve, an oil inlet system and an automatic control system, wherein the throttle valve is arranged on the oil feeder body. The invention enables a sensing element not to be influenced by the high temperature of an engine by adopting a relatively independent driving and sensing device, precisely acquires the opening of an oil needle of a carburetor and prevents the signal disorder; an ECU (Electronic Control Unit) controls oil needle lift according to a running signal and throttle valve opening according to an oil needle lift signal and other parameter signals, verifies and detects whether the throttle valve opening is a needed opening or not by using a position sensor signal of a throttle valve opening mechanism so as to prevent the signal disorder, step losing and uncontrollability, therefore the optimal matching and the control of the throttle valve opening and the 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 oil supply system, in particular to an electronically controlled wheel-type transmission sensor fine-tuning intelligent oil 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 con...

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 operated by the driver In the case of not knowing the driving resistance, the speed change device that is only operated and controlled based on experience often forces the engine speed to drop to work in the low-efficiency area due to the increase in driving resistance when starting, uphill, and heavy loads, 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

[0020] In order to solve the above problems, in the prior art, a sensor for detecting the opening of the oil needle is arranged on the carburetor of the engine. After the sensor detects the opening of the oil needle, the opening signal is sent to the electronic control unit (ECU), The electronic control unit (ECU) automatically adjusts the shifting operation according to the opening signal; this structure cannot reasonably match the fuel intake and intake air volume, and the actual intake air volume is quite different from the theoretical intake curve, which is unfavorable to the engine running state Affects, affects emissions and reduces engine operating efficiency

Moreover, the sensor of this structure is arranged near the oil needle plunger of the carburetor, especially when the Hall element with high precision and strong adaptability is used, it is necessary to arrange auxiliary parts such as magnets, which will make the carburetor The structure itself is complex and the volume increases, which is not suitable for layout and installation; and the high temperature in the engine will be transmitted to the sensor through the oil needle, affecting the accuracy of the sensor's detection parameters, and even sending out completely wrong signals, affecting the normal issuance of the next command , thereby affecting the normal driving of motor vehicles
