Description

Technical Field

[0001] The utility model relates to the field of ignition testing, in particular to a high-precision simulation test bench based on a motorcycle ignition device. Background Art

[0002] With the rapid development of the motorcycle industry and the widespread application of electronic control system technology, the performance and stability of motorcycle ignition controllers have a crucial impact on the performance of the entire vehicle. The motorcycle ignition controller is an important component of the engine management system, which is related to the vehicle's power, fuel economy, and exhaust emission standards. Therefore, high-precision testing of the performance of the ignition controller is a key link to ensure the overall performance of the motorcycle. At present, the test of motorcycle ignition controllers mainly adopts manual testing, which not only increases labor costs, but also has a high misjudgment rate and cannot guarantee the product quality of motorcycle ignition controllers.

[0003] In the prior art, for example, patent publication number CN105446323B discloses a motorcycle ignition controller test platform, which realizes automatic and comprehensive detection of motorcycle ignition controllers and effectively ensures the quality of motorcycle ignition controllers. However, motorcycle ignition is affected by the environment, which directly affects the intake, and the ignition performance of the ignition controller is different under different intake conditions. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a high-precision simulation test bench based on a motorcycle ignition device, which can simulate the ignition state under different intake conditions in a mixed manner, so as to perform simulation tests.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: a high-precision simulation test bench based on a motorcycle ignition device, comprising a test machine, a controller is provided on the test machine, an internal combustion engine transmission structure is provided in the test machine, an ignition device installation port is provided on the test machine, and the test machine is provided with an intake pipe and an exhaust pipe;

[0006] The exhaust pipe is connected to a gas detection component, which is used to detect the gas composition in the exhaust pipe;

[0007] The air inlet pipe is connected with an air supply box, an injector is arranged in the air supply box, the injector is connected with an oil tank and a gas mixing chamber, the gas mixing chamber is connected with a nitrogen tank and an oxygen tank, both the nitrogen tank and the oxygen tank are provided with an electric control flow valve, the air supply box is provided with an air suction pipe, an oxygen content detector is arranged in the air suction pipe, and the air suction pipe is connected with the gas mixing chamber;

[0008] The electric control flow valve, the gas detection component and the oxygen content detector are all electrically connected to the controller.

[0009] The above scheme has the following beneficial effects:

[0010] 1. In this solution, an ignition device is installed at the ignition device installation port to perform an ignition simulation test. The test machine is provided with an internal combustion engine transmission structure, which can simulate the power transmission mechanism after ignition, thereby detecting whether the ignition device is qualified.

[0011] 2. In this solution, the test machine takes in air through the air inlet. The user can change the air-fuel ratio during the ignition process by adjusting the gas output from the air supply box, and detect the performance of the ignition device under different air-fuel ratios. Air can be inhaled into the gas mixing chamber from the air intake pipe, and the oxygen content detector can detect the oxygen content in the current inhaled air. After the controller obtains the detection value of the oxygen content detector, it adjusts the release amount of the nitrogen tank and the oxygen tank through the electronically controlled flow valve according to the current oxygen content in the air. The nitrogen tank is used to reduce the proportion of oxygen in the mixed gas, and the oxygen tank is used to increase the proportion of oxygen in the mixed gas. By changing the proportion of oxygen in the mixed gas, the ignition effect under different oxygen contents is detected. The injector mixes with the oil and gas to deliver the combustible mixed gas to the test machine.

[0012] 3. In this solution, the ignition effect is detected by a gas detection component, which can detect the degree of combustion of the combustible mixed gas, thereby evaluating the ignition effect.

[0013] Compared with the existing technology, different intake environments are constructed through the adjustment of the air supply box for ignition detection, and an ignition simulation test is carried out on the ignition device. The intake gas is proportioned after detecting the oxygen content in the air, so as to obtain the performance of the ignition device under different external environments and air-fuel ratios, so as to accurately control the oxygen content, and judge the ignition effect by detecting the exhaust gas components after combustion.

[0014] Furthermore, a rotation speed meter is provided on the output shaft of the testing machine, and the rotation speed meter is electrically connected to the controller.

[0015] Beneficial effect: The speed measuring instrument can detect the speed output by the test machine, so as to evaluate the output stability of the speed.

[0016] Furthermore, a torque meter is provided on the output shaft of the testing machine, and the torque meter is electrically connected to the controller.

[0017] Beneficial effects: The torque tester can detect the torque output by the testing machine, thereby evaluating the output stability of the torque.

[0018] Furthermore, the gas detection component includes a detection box, which is connected to the exhaust pipe, and an exhaust gas analyzer is fixedly connected to the detection box.

[0019] Beneficial effect: After being generated, the exhaust gas will be discharged into the detection box. The exhaust gas analyzer in the detection box will detect the exhaust gas composition to determine whether the ignition of the ignition device causes the combustible mixed gas to burn fully.

[0020] Furthermore, the detection box is connected to a first one-way valve and a second one-way valve respectively, and the second one-way valve is connected to an exhaust gas storage container.

[0021] Beneficial effects: Usually, the exhaust gas after combustion will be discharged into the external environment, making the detection data impossible to trace. The detection box can control the flow direction of the exhaust gas by controlling the opening and closing of the first one-way valve and the second one-way valve. When the exhaust gas analyzer detects an abnormality, the first one-way valve is closed and the second one-way valve is opened, so that the abnormal exhaust gas flows into the exhaust gas storage container, which is convenient for subsequent detailed detection and analysis of the abnormal condition and tracing the cause of the abnormality.

[0022] Furthermore, a cyclone is rotatably connected in the gas mixing chamber.

[0023] Beneficial effect: The cyclone can rotate driven by the airflow, further disturbing the airflow, so that the air can be fully mixed with the airflow output from the nitrogen tank and the oxygen tank.

[0024] Furthermore, an air filter is provided at the connection point between the gas mixing chamber and the fuel injector.

[0025] Beneficial effect: The air filter can filter out dust particles or water droplets in the air, reducing the impact on the ignition process.

[0026] Furthermore, the gas mixing chamber is provided with a semiconductor cooling sheet, and a temperature detector is provided in the gas mixing chamber.

[0027] Beneficial effect: The ignition effect is also affected by temperature. The semiconductor refrigeration sheet can simulate a low-temperature environment to detect the ignition effect in a low-temperature environment.

[0028] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is further described in detail through specific implementation methods:

[0037] As attached Figure 1 To Attachment Figure 3As shown: a high-precision simulation test bench based on a motorcycle ignition device, comprising a test machine 1, a controller is fixedly connected to the test machine 1 by screws, an internal combustion engine transmission structure 2 is arranged in the test machine 1, an ignition device installation port 3 is arranged on the test machine 1, the ignition device installation port 3 is used for detachably connecting the ignition device, the ignition logic and ignition action are controlled by the controller after the ignition device is installed, and the test machine 1 is connected to an intake pipe 4 and an exhaust pipe 5;

[0038] The exhaust pipe 5 is connected to a gas detection component, which includes a detection box 15. The detection box 15 is connected to the exhaust pipe 5. An exhaust gas analyzer 16 is fixedly connected to the detection box 15. The model of the exhaust gas analyzer 16 is MS400. The detection box 15 is respectively connected to a first one-way valve 17 and a second one-way valve 18. The second one-way valve 18 is connected to an exhaust gas storage container 19.
