Electronic tube type transmission and sensing fine trimming intelligent oil feeder

Abstract

The invention discloses an electronic tube type transmission and sensing fine trimming intelligent oil feeder which comprises an oil feeder body, an air damper and an oil inlet system arranged on the oil feeder body, and an automatic control system. A relatively independent oil needle lift detector is adopted by the automatic control system to prevent a sensing element from being influenced by the high temperature of an engine and avoid the occurrence of unbalanced signals; an electric control unit ECU controls the oil needle lift according to a traveling signal, controls the opening of the air damper by being combined with other parameters according to an oil needle lift signal, and utilizes the signal of a position sensor on an opening mechanism of the air damper to check and detect whether the opening of the air damper is the required opening or not, avoid signal disordering, dropping and losing control, and lead the opening of the air damper to reach optimal match and control with the oil needle lift; therefore, combustible mixed air required by an ideal air-fuel ratio is realized; and the power targets (load and rotating speed) of the engine is lead to realize optimal matching and control with the oil needle lift as well as the opening and gear of the air damper.

Description

technical field [0001] The invention relates to a component of an engine oil supply system, in particular to an electronically controlled barrel-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 co...

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
