Description

Technical Field

[0001] This utility model relates to autonomous maintenance of emission equipment, and in particular to an auxiliary device for autonomous maintenance of emission equipment. Background Technology

[0002] With the country's increasing emphasis on ecological and environmental protection, stringent emission standards have been imposed on the automotive industry. As a leading enterprise in my country's multi-cylinder, small-bore internal combustion engine industry, we have taken the lead in introducing multiple sets of advanced emission control equipment.

[0003] This emissions testing equipment is specifically designed for the automotive industry, helping to optimize engine and vehicle design to meet stringent emissions regulations. It boasts high precision, high sensitivity, and a fast response time, ensuring accurate and reliable test results. To quickly master this high-precision equipment, mastering its independent maintenance and repair is an urgent task for us, as maintenance technicians. Traditional maintenance methods often fail to meet the cleanliness and precision requirements of components, and the response time cannot meet transient emissions testing requirements. This can even damage critical analyzers and sensors. Furthermore, core data and status data cannot be effectively collected and processed, hindering the tracking of equipment operation and preventing guidance for independent maintenance and preventative repairs, thus increasing the risk of equipment downtime.

[0004] To ensure the normal operation and extend the service life of emission equipment, we have proposed an auxiliary device for autonomous maintenance of emission equipment by making full use of existing resources and through the introduction, absorption and digestion of foreign technologies.
