Product Description
SSCD22-1000-4000 22kW Diesel Engine Electric Dynamometer Test Bench System
Product Description
This system, centered around a small AC dynamometer and compatible with small 22kW diesel engines, employs four-quadrant variable frequency inverter technology for efficient energy recovery (reintroduction efficiency >85%). Equipped with the XLE-1000 measurement and control system, it supports simultaneous multi-channel acquisition and analysis of key parameters. It automatically executes test cycles specified in standards such as GB/T 18297 and integrates equipment such as a small smoke meter and high-precision air flow meter, meeting the full performance testing needs of small diesel engines used in mini commercial vehicles, small agricultural machinery, and general-purpose power equipment.
Engine Test Bench Components
SSCD22-1000-4000 22kW Diesel Engine Electric Dynamometer Test Bench System Components
1) Electric Dynamometer: Seelong small AC electric dynamometer with HBM T40B torque flange (0-500Nm, suitable for low-power torque range), air cooling (simplified heat dissipation structure), elastic coupling to reduce vibration, and supports stable operation from 0-4500rpm (matching the high speed characteristics of low-power engines).
2) Variable frequency inverter system: ACS880 series small frequency converter with direct torque control (DTC), control accuracy of 0.01Hz, adapted for low-power energy recovery scenarios, and energy feedback efficiency >85% (avoiding energy waste in high-power modules).
3) XLE-1000 Measurement and Control System: Provides overall control of the test bench, enabling low-power operating condition settings through bus communication with the inverter system. It integrates external auxiliary equipment for centralized control and supports automated execution of dedicated low-power engine test processes (such as idle stability and light-load fuel consumption testing).
4) Data Acquisition System: 16-channel high-speed acquisition module (sampling frequency 200Hz, meeting the needs of low-power parameter acquisition) with integrated signal conditioning function, which transmits key parameters such as torque, speed, fuel consumption in real time to the measurement and control system for analysis and storage.
5) Auxiliary equipment: Small coolant thermostat (15L/min, suitable for low-power cooling requirements), AVL small opaque smoke meter, dual-channel electronic throttle, small exhaust back-pressure valve and low-pressure fuel pressure sensor (suitable for low-power engine fuel systems).

Technical Advantages
SSCD22-1000-4000 22kW Diesel Engine Electric Dynamometer Test Bench System Core Advantages
1) Precise adaptation for low-power engines: The loading algorithm is optimized for 22kW-class models, which can stably execute low-power-specific operating conditions such as light load and idling, meeting the requirements of a 500-hour endurance test (matching the usage intensity of low-power engines).
2) Lightweight and energy-saving design: The overall weight of the equipment is 15% lighter than that of a traditional test bench with the same power. Combined with a low-power energy recovery system, the test energy consumption is reduced by more than 30% compared to a resistive load machine, making it suitable for small-batch testing scenarios in laboratories.
3) Low cost and easy operation and maintenance: Modular components are small in size and do not require large-scale infrastructure for installation; wearing parts are of universal specifications and have low replacement costs, with annual maintenance time ≤15 hours (lowering the threshold for use by small businesses).
4) Flexible compatibility across multiple scenarios: Supports engine testing for micro-commercial vehicles, small agricultural machinery, and 10-30kVA generator sets. It can quickly switch operating modes to meet the diverse testing needs of small-power models.
Typical Applications
SSCD22-1000-4000 22kW Diesel Engine Electric Dynamometer Test Bench System Applications
1) Micro-commercial vehicle/light truck R&D: 22kW diesel engines for mini trucks under 3 tons and 6-9 seat light buses are tested for idle stability, low-load fuel consumption, and emission performance.
2) Small agricultural machinery verification: Diesel engines suitable for walking tractors and small harvesters are used to simulate light-load operating conditions in the field to verify power matching and reliability.
3) Small general power testing: Provides power calibration, fuel consumption evaluation and starting performance testing for 10-30kVA generator sets and 22kW class diesel engines for small industrial water pumps.
4) After-sales maintenance quality inspection: Used by auto repair shops and agricultural machinery stations to verify the performance recovery of small-power diesel engines after repair, and quickly issue simple test reports.
