When it comes to heavy machinery, reliability and power are paramount. Liebherr, a name synonymous with innovation and excellence in engineering, stands tall as a pioneer in the realm of heavy equipment and machinery. From towering cranes to robust excavators, Liebherr’s engineering prowess extends to the heart of these machines. We delve into the world of dyno testing a Liebherr engine, uncovering the meticulous process behind unleashing the raw power concealed within. Before we embark on the journey of dyno testing, it’s crucial to understand the foundation upon which Liebherr engines are built. With decades of engineering expertise and commitment to quality, Liebherr engines are crafted to withstand the most demanding environment and deliver unparalleled performance. Each component is meticulously designed and rigorously tested to ensure reliability, efficiency and longevity. 1 Preparation: The engine undergoes meticulous preparation before being mounted onto the dynamo meter. This includes ensuring all connections are secure, fluids are filled to the appropriate levels, and sensors are properly calibrated. 2 Mounting: The engine is carefully mounted onto the dynamometer, a specialized device designed to simulate real-world operating conditions. Precision is paramount during this step to ensure accurate results. 3 Initial checks: Once mounted, a series of initial checks are conducted to verify proper alignment, connection integrity, and functionality of all engine systems. 4 Warm-up: The engine is started and allowed to warm up to operating temperature. This ensures consistent results and minimizes the risk of damage during testing. 5 Baseline testing: With the engine warmed up , baseline tests are conducted to establish initial performance metrics. This includes measuring power output, torque, fuel consumption, and emissions at various RPM levels. 6 Load testing: The engine is subjected to progressively increasing loads to simulate different operating conditions, such as idle, partial load and full load. This allows engineers to assess performance across the entire operating range and identify any potential issues or optimization. 7 Data analysis: Throughout the testing process, data is continuously collected and analyzed in real-time. Advanced instrumentation and software are used to monitor performance metrics and identify trends or anomalies. 8 Optimazation: Based on the data analysis, adjustments may be made to optimize engine performance. This could involve fine-tuning fuel injection timing, adjusting air-fuel ratios, or optimize turbocharger boost pressure. 9 Validation: Once testing is complete, the results are meticulously reviewed and validated against predetermined criteria and specifications. Any deviations or anomalies are thoroughly investigated to ensure accuracy and reliability. 10 Reporting: Finally, a comprehensive report is generated detailing the results of the dyno testing, including performance metrics, observations, and any recommendations for further optimization or refinement. Dyno testing a Liebherr engine is more than just a routine procedure – it’s a testament to the unwavering commitment to excellence that defines Liebherr’s engineering philosophy. By subjecting their engines to rigorous testing and analysis, Liebherr ensures that each engine delivers the uncompromising performance, reliability, and efficiency that customers expect. In conclusion, dyno testing a Liebherr engine is not just about measuring power output. It’s about unlocking the true potential of these remarkable engines and ensuring they exceed expectations in the most challenging environments imaginable.
Modified atmosphere packaging (MAP) ensures the taste, nutritional content and freshness of food without the use of preservatives and additives. Take, for example, fruit and vegetable preservatives, fresh fruits and vegetables that still breathe after being picked. They consume oxygen and produce carbon dioxide, which increases carbon dioxide levels and decreases oxygen levels. Using a highly permeable membrane, oxygen can be supplied and carbon dioxide removed by exchanging the packaging gas with the atmosphere. Certain equilibrium concentrations of gases in the package are achieved when the air permeability is equal to the respiration rate of fruits and vegetables. Then, without anaerobic respiration, fruits and vegetables can sustain a weaker respiratory rate.
MAP/CAP, Modified Atmosphere Packaging/Controlled Atmosphere Packaging) scope
(1) Vacuum packaging: the residual oxygen content is required to be below 0.5-1%;
(2) Nitrogen-filled packaging: after vacuuming and filling with nitrogen, the oxygen is further diluted to reduce the residual oxygen content;
(3) Filling with protective gas packaging: replacing air to keep food preservative and fresh;
(4) Packages enclosed in oxygen absorbers or carbon dioxide/ethylene propellants: reduce oxygen and generate modified atmosphere; replace air to delay oxidation reaction of food; fill gas for mixed gas; prevent packaging from slumping due to CO2 seepage.
(5) Other gases: composed of argon, nitrogen dioxide, carbon monoxide, sulfur dioxide and other protective gases
