Comprehensive Diesel Engine Test and Diagnostic Bench (TBM/D)


PL-410309
The Advanced Diesel Test and Diagnostic Bench for Internal Combustion Engines, “TBM/D”, is a state-of-the-art system developed by EDIBON to perform detailed evaluations and precise diagnostics on diesel engines. Designed for use by engineers and technical professionals, this unit enables thorough analysis of engine behavior, fault detection, and performance optimization, ensuring high efficiency and reliability in automotive system maintenance and development.
At the heart of this test bench lies the internal combustion engine, which serves as the core element of analysis. Its purpose is to transform the chemical energy from diesel fuel into mechanical power through combustion within the cylinders. The unit allows for the study of this energy transformation process, including the assessment of combustion efficiency, exhaust gas characteristics, and overall engine performance—key elements for maximizing the performance of diesel engines.
- Air Intake System: This system ensures the engine receives the oxygen required for combustion. It allows users to monitor and analyze both the volume and quality of air intake, which are critical for achieving efficient combustion and directly influence power output and fuel efficiency.
- Exhaust Gas System: Responsible for eliminating combustion by-products and minimizing noise, the exhaust system replicates that of a real vehicle. This setup enables users to analyze gas flow and system behavior, evaluate engine efficiency, and study exhaust gas composition to determine environmental impact and regulatory compliance.
- Fuel Supply System: Controls the fuel injection process, managing the quantity of fuel delivered into the cylinders. This precision directly affects engine efficiency and power output. The TBM/D bench enables the evaluation and adjustment of various fuel injection parameters, helping to refine consumption rates and performance.
- Cooling System: Designed to dissipate the heat generated during combustion, this system prevents engine overheating and helps maintain optimal operating temperature. Monitoring cooling performance is essential for assessing its effect on long-term engine durability.
- Starting System: Features an electric motor that initiates the combustion cycle. This allows for the analysis of engine response during cold starts and varying environmental conditions, contributing to the evaluation of system reliability under real-world scenarios.
The unit is equipped with advanced instrumentation and integrated sensors that deliver real-time data on vital engine metrics, including pressure, temperature, RPM, and fuel/air volumes. This data is crucial for in-depth performance analysis and allows for accurate system calibration to enhance engine operation.
The TBM/D also supports individual subsystem evaluation as well as complete tests simulating real driving conditions. These simulations are essential for understanding how the engine behaves under stress, high loads, or extreme temperatures.
Accurate diagnostics are vital for vehicle performance and longevity. With the TBM/D Test and Diagnostic Bench, users can identify mechanical or performance issues early, enabling preventative maintenance before major failures occur. The system supports real-time error correction and tuning, improving reliability throughout the engine's operational life. By simulating a variety of scenarios, it ensures comprehensive analysis and long-term efficiency.
