Product Details
KGD-WQ-505 New Fuel Engine Exhaust Gas Analysis System
Product Introduction
The KGD-WQ-505 New Fuel Engine Exhaust Gas Analysis System is a
specialized detection device for engine exhaust gases. The system
combines Tunable Diode Laser Absorption Spectroscopy (TDLAS), Non -
Dispersive Ultraviolet Absorption Spectroscopy (NDUV), and Gas
Filter Correlation Infrared Absorption Spectroscopy (GFC) to
simultaneously measure the concentrations of NH₃, NO, NO₂, and N₂O
in engine exhaust gases with low interference and high precision.
It is used for the development and research of engines and after -
treatment systems, and provides reliable test data for reducing NH₃
emissions. Aiming at the characteristics of internal combustion
research and development of new fuels (such as NH₃ blended fuels,
biofuels, compressed natural gas, e - fuels, etc.) and in line with
the requirements of the next - generation emission regulations Euro
7 and China 7, the system helps users quickly obtain accurate
reference data.
Product Features
- Analyzes four nitrogen compounds: NH₃, NO, NO₂, N₂O
- Meets various domestic and international standard requirements:
Euro 7, China 7, CFR 1065 (N₂O)
- Wide measurement concentration range: Enables high - precision
measurement over a large concentration range for nitrogen oxides
- Strong anti - interference ability: Laser spectroscopy technology
is not interfered by background gases
