Overview
Gasboard-9802 is a full-flow dilution constant volume sampling (CVS) system that mixes engine exhaust with dilution air at constant flow for bag sampling, continuous gas and particulate analysis and filter sampling. With system error below 2% of reading (Euro 6/7) and multiple flow levels, it suits engines of various fuels and displacements.
Key Features
- With a wide range of diluted exhaust flow options, it accommodates the testing of engines and vehicles powered by various fuels and with different displacements.
- Integrated with a high-performance heat exchanger and a venturi tube, it ensures precise control of diluted exhaust flow, guaranteeing system accuracy and stability.
- Combined with the constant temperature control function of the heat exchanger and the air bag cabinet, it effectively prevents the condensation of diluted exhaust.
- Equipped with a high-performance dilution air filter, it can meet the requirements for emission testing at ultra-low emission levels.
- System error is less than 2% of reading, complying with Euro 6/7 standard.
- A variety of total exhaust flow levels are available for different displacement engines.
- Modular design facilitates fast integration, minimal maintenance and easy upgrades.
- The compact design ensures equipment installation in high adaptation with other facilities such as engine and dynamometer on site.
