Electronic control transmission sensing fine turning intelligent oil feeder

Abstract

The invention discloses an electronic control transmission sensing fine turning intelligent oil feeder, which comprises an oil feeder body, an automatic control system, and a throttle valve and an oil inlet system which are arranged on the oil feeder body. In the oil feeder, a throttle valve structure and an oil inlet structure are combine with each other and are matched with the automatic control system, an electronic control unit (ECU) is used for controlling the rise of an oil needle according to a running signal, controlling the aperture of the throttle valve by combining other parameter signals according to a rise signal of the oil needle and verifying and detecting whether the aperture of the throttle valve is the required aperture or not by using a position sensor signal on a throttle valve aperture mechanism to avoid signal disorder, step-off and uncontrollability, so that the optimal matching and control between the aperture of the throttle valve and the rise of the oil needle can be realized; therefore, a burning mixture required by a theoretical air-fuel ratio can be realized, so that the optimal matching and control between the power target (load and rotating speed) of an engine and the rises of the oil needle as well as between the aperture of the throttle valve and a tap position can be realized.

Description

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

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
