Description:
The GT-CO4T-Four Gas Exhaust Analyzer with Printer employs cutting-edge technology to measure five crucial gases in petrol emissions: HC, CO, CO2, O2, and NOx. With a focus on troubleshooting, particularly using O2 and CO2 readings, this analyzer provides valuable insights into engine performance and emissions diagnosis. Beyond the standard measurements, it recognizes the impact of additional exhaust components like water vapor (H2O), sulfur dioxide (SO2), hydrogen (HO), and particulate carbon soot (C).
Key Features:
- Comprehensive Gas Measurement:
-
HC, CO, CO2, O2, and NOx: Accurate measurement of these gases for a detailed emission analysis.
-
Water Vapor (H2O): Recognizes the presence of water vapor in exhaust emissions.
-
Sulfur Dioxide (SO2): Monitors levels of sulfur dioxide for a comprehensive analysis.
-
Hydrogen (HO): Detects hydrogen, a key factor in emission diagnostics.
-
Particulate Carbon Soot (C): Measures particulate carbon soot for a more thorough examination.
- Troubleshooting Tools:
-
CO and O2 Readings: Indicators of rich or lean engine conditions, aiding in troubleshooting.
-
Relationship between CO and O2: Understand the inverse correlation for effective diagnostics.
- General Rules of Emission Analysis:
-
CO and O2 Relationship: Insight into rich and lean running engines based on CO and O2 readings.
-
HC Increase and Lean Misfire: Correlation between HC and O2 readings in the case of a lean misfire.
-
CO2 Decrease Indicator: Highlights air/fuel imbalance or misfire when CO2 decreases.
-
Specific Conditions for Misfires: Identifies conditions leading to misfires based on HC, CO, and O2 levels.
Technical Information:
-
Engine Conditions and Gas Readings:
-
Rich Running Engine: Elevated CO readings.
-
Lean Running Engine: Increased O2 readings.
-
Lean Misfire Impact: HC and O2 increase simultaneously.
-
Air/Fuel Imbalance or Misfire: Decrease in CO2 readings.
-
Misfire Indicators:
-
Rich Mixture Misfire: High HC and CO, with high O2.
-
Lean or EGR Diluted Mixture Misfire: High HC, low CO, and high O2.
-
Mechanical or Ignition Misfire: High HC, normal to marginally low CO, and high O2.
-
False Air or Marginally Lean Mixture Misfire: Normal to marginally high HC, normal to marginally low CO, and high O2.
