Description

[0002] In order to pursue high thermal efficiency of diesel engines, it is necessary to reduce the power loss caused by various accessories; the crankshaft in traditional engines drives the balance shaft to rotate at the same frequency, which is an important power loss item. The traditional mechanical dual-axis balancing mechanism has a simple structure and reliable performance, but it cannot adjust the balance shaft speed according to the needs of different engine operating conditions. It is easy for the crankshaft and the balance shaft to rotate synchronously. When the value of the spectrum diagram (a three-dimensional graph of the engine vibration intensity changing with speed and oil volume) does not exceed the calibration threshold, the engine vibration is almost negligible, and the balance shaft is not needed to reduce vibration at this time; when the spectrum diagram value exceeds the calibration threshold, the balance shaft needs to rotate at the vibration reduction rate required by the current engine operating state to achieve a better shock absorption effect.

[0003] The traditional mechanical dual-axis balancing mechanism is prone to poor vibration reduction effect and high power consumption; the active balancing shaft technology is to install a balancing shaft parallel to the crankshaft, and offset the unbalanced force caused by the piston movement through high-speed rotation, but this solution cannot be adjusted with the vibration and speed of the engine; and the advanced vibration isolation system, such as hydraulic or electronically controlled engine brackets, is used to reduce the impact of engine vibration transmitted to the car body; however, this solution can only improve the riding experience, but cannot reduce the vibration of the engine itself, which will affect the life of the engine.

[0053] A non-road diesel engine intelligent drive vibration reduction balance control method, comprising the following steps:

[0054] The speed, fuel injection amount and vibration intensity parameters of the target engine in the working state are measured, and the driving mechanism and the balancing mechanism 4 of appropriate specifications and models are selected according to the obtained parameters; the operating parameters of the engine are obtained according to the speed of the engine to be damped and the vibration conditions during the operation process, and then the model of the DC motor 14 is selected according to the model and size of the engine, and the first balancing shaft 5 and the second balancing shaft 7 are designed according to the design requirements;

[0055] Furthermore, when obtaining the engine operating parameters, the speed sensor is used to measure the speed signal, the electronic control system controls the injection amount, and the vibration sensor measures the vibration intensity, and all the parameter signals are transmitted to the ECU to obtain the corresponding data; according to the obtained speed and injection amount parameter data and the known model size, maximum speed torque of the engine, the drive mechanism and the balancing mechanism 4 of appropriate specifications and models are selected. Since the balancing mechanism 4 is installed under the main oil pan 1, it is necessary to select a suitable drive mechanism and balancing mechanism 4 according to the overall size of the engine; and then the model of the DC motor 14 is determined by the maximum speed of the engine. The DC motor 14 serves as the rotational power of the drive mechanism, so that the speed of the first balance shaft 5 and the second balance shaft 7 is the same as the engine speed or twice the engine speed. This results in the DC motor 14 to select a model according to the maximum speed of the engine. If the maximum speed of the engine is small, the power of the DC motor 14 can be selected to be small.

[0058] The engine is started, and the output of the driving mechanism is controlled according to the vibration of the engine. The first balance shaft 5 and the second balance shaft 7 rotate in opposite directions to balance the vibration of the engine. The engine includes four working states during operation:

[0059] The first working state: when the engine is in working state, the speed sensor measures the speed, the electronic control system controls the fuel injection amount, and the vibration sensor measures the engine vibration intensity, and all transmit signals to the ECU.

When the value does not exceed the calibration threshold, the engine vibration is ignored, and the ECU controls the DC motor 14 not to work;

[0060] The second working state: when the engine is in working state, the speed sensor measures the speed, the electronic control system controls the injection amount, and the vibration sensor measures the engine vibration intensity, and all transmit signals to the ECU. The ECU forms a spectrum diagram (a three-dimensional graph of engine vibration intensity changing with speed and oil amount) according to the speed, injection amount and vibration intensity data, and processes the data; according to the needs of the driver, the comfort level is selected, and the calibration threshold is set to 1. When the value exceeds the calibration threshold, the second-order inertia force inside the engine is large and unstable, then the ECU controls the DC motor 14 to make the first balance shaft 5 start to accelerate and work, to ensure that the working speed of the first balance shaft 5 and the second balance shaft 7 is twice the crankshaft speed, which is used to eliminate the imbalance caused by the second-order inertia force;

[0061] The third working state: when the engine is in working state, the speed sensor measures the speed, the electronic control system controls the injection amount, and the vibration sensor measures the engine vibration intensity, and all transmit signals to the ECU. The ECU forms a spectrum diagram (a three-dimensional graph of engine vibration intensity changing with speed and oil amount) according to the speed, injection amount and vibration intensity data, and processes the data; according to the needs of the driver, select fuel saving, set the calibration threshold to 5, when the value does not exceed the calibration threshold, the engine vibration is ignored, and the ECU controls the DC motor 14 not to work;

[0062] The fourth working state: when the engine is in working state, the speed sensor measures the speed, the electronic control system controls the injection amount, and the vibration sensor measures the engine vibration intensity, and all of them transmit signals to the ECU. The ECU forms a spectrum diagram (a three-dimensional graph of engine vibration intensity changing with speed and oil amount) according to the speed, injection amount and vibration intensity data, and processes the data; according to the needs of the driver, choose to save fuel consumption, set the calibration threshold to 5, when the value exceeds the calibration threshold, the second-order inertia force inside the engine is large and unstable, then the ECU controls the DC motor 14 to make the first balance shaft 5 start to accelerate and work, to ensure that the working speed of the first balance shaft 5 and the second balance shaft 7 is twice the crankshaft speed, which is used to eliminate the imbalance caused by the second-order inertia force.
