Structure:
No-load dynamometer is mainly composed of the following components:
Dynamometer: A platform for supporting and fixing an engine, usually with a bracket with adjustable height and angle.
Motor: A motor used to simulate engine load. Different working conditions are simulated by adjusting the load and speed of the motor.
Sensor: used to measure engine speed, torque, temperature and other parameters.
Control system: used to control the load and speed of the motor and record the measurement data.
Data acquisition and analysis system: used to collect, store and analyze measurement data, and generate test reports and curves.
Test principle:
The test principle of no-load dynamometer is to simulate the working state of the engine when it is no-load, that is, the engine runs without external load. During the test, the motor controls the speed and provides the corresponding torque by simulating the load of the engine. At the same time, the sensor measures the engine speed, torque, temperature and other parameters, and transmits the data to the control system and data acquisition system for recording and analysis.
How to use:
The general steps for testing the engine with no-load dynamometer are as follows:
Preparation: Install the engine on the dynamometer to ensure a stable connection. Connect the sensor as required, and ensure the correct installation and calibration of the sensor.
Start the dynamometer: start the dynamometer motor and control system, conduct preheating and self-inspection to ensure that the equipment is in normal working condition.
Setting test parameters: according to the test requirements, set test parameters, including speed range, measurement time interval, etc.
Test: Start the engine and run it to no-load state. The control system matches the motor load and speed with the engine and records the measured data.
Data analysis and report generation: through the data acquisition and analysis system, the measured data are processed and analyzed, test reports and charts are generated, and the performance indexes of the engine are evaluated.
