Changchai product upgrade has a new emission test tool

Recently, the software and hardware adaptability upgrade of AC dynamometer in the test room of Changchai Technology Center's product test room has been completed. This industry-class emission test system can meet the vehicle country's five, six, and non-roads. Test requirements for all power ranges of National III and National IV diesel engines. The successful completion of the complete set of National Five Emissions Test System Transformation Project provides a new emission test tool for the company's product upgrade.

Technician calibrates the full flow dilution emission test system

It is understood that after the successful transformation of the National Five Emissions Test System, the following results were achieved: First, an AVL AC electric dynamometer was added to each of the company's product testing rooms, No. 1 and No. 2, and a medium-sized full flow was introduced. Dilution emission test system and calibration equipment, dynamic response, automatic control system with test bench is suitable for various test applications of the engine. Secondly, after upgrading the main control computer and main control software of the 220 kW AC electric dynamometer in the test room No. 3, the original gas direct sampling and particle partial flow sampling system can be used, and the newly purchased one can be used. The full-flow dilution sampling system expands the scope of use of the original equipment to meet the development and test needs of large and small power diesel engines. Third, the current software modeling process is simpler and more convenient to use. It can save a lot of preliminary work and speed up the matching and calibration of the fuel system, air intake system and aftertreatment system, thus improving the product development capability and speeding up the product development progress.

Emission test on the 220kW AC electric dynamometer

At present, the company's non-road country four prototype emission calibration, production consistency verification and other work has been launched in the new emission test system, the follow-up vehicle country six prototype will also use the new test system to carry out emission calibration. Obviously, the completion of the technical transformation project provides the company with advanced emission testing technology guarantee for the development of new high-end energy-saving and environmentally friendly engines.
