Environmental Emissions Inspection Line

Requirements and system scope

• The system is published for passenger vehicles, commercial vehicles, and heavy trucks, with local-regulation customization available.
• Its steady-state test process uses ASM5025 (5024) and ASM2540 operating segments to simulate regulated road loads.

Inspection chain

The published CTASM-3 configuration combines a chassis dynamometer, five-gas analyzer, cooling equipment, driver aid, safety limits, inertia simulation, engine-speed measurement, environmental station, and computer control.

During testing, the system applies the required load simulation to measure CO, HC, and NOx pollutant concentrations.

System features

• Supports acceleration-simulation testing specified by GB18285 and double-idle testing specified by GB14621
• Supports national-standard emissions testing and user-specified operating conditions
• Uses automatic zero calibration for a high degree of automation
• Provides a menu-driven operating interface
• Uses gas-pump and filtration design intended to reduce long-term sensor contamination
• Uses a water-resistant structure intended to improve instrument stability
• Supports RS-232 communication with a PC
