Here are some tips to determine if your Liugong excavator parts comply with current regulations:
Check emission labels and certifications:
The engine, turbocharger and other key emission components will have labels or certifications indicating they meet EPA Tier 3, Tier 4 or Stage V emission standards. These represent progressively tighter standards. Make sure your equipment qualifies for the appropriate tier/stage.
Review equipment build specifications:
The model build specifications will list details like engine model number, power ratings, emission control technologies used like SCR catalysis, EGR, etc. Match these against the required specs for your geographic region and type of use.
Inspect emission control components:
Look for components like diesel particulate filters, selective catalytic reduction systems, EGR coolers, etc. These components are required to meet higher emission tiers/stages. Their condition also impacts compliance.
Check sensors and diagnostic systems:
Sensors like oxygen sensors, NOx sensors and advanced diagnostics are needed to properly monitor emissions and ensure components are working as intended. Faulty or missing systems compromise compliance.
Examine records and traceability:
Reliable records showing equipment build details, component versions, test results, etc. should be available to establish a proper build traceability and compliance history. Lacking records raise doubts about regulatory compliance.
Consider getting diagnostic tests done:
Professional exhaust emission testing using portable analyzers can determine if your equipment actually meets certified on-road or off-road emission limits for different pollutants like HC, CO, NOx and particulate matter. Official testing provides the definitive check.
Ensure proper maintenance:
Compliance is not just about build specifications but also ongoing maintenance and part replacement to keep all emission critical parts in good working condition. Lack of routine service undermines the designed emission performance.
Check for any modifications:
Any unauthorized modifications to emission control systems or engine calibrations must be reverted before the equipment can be considered properly complaint again. Equipment compliance is based on its original as-built configuration.
