Experimental Underperformance Detection of a Fixed-Speed Diesel–Electric Generator Based on Exhaust Gas Emissions
Abstract
:1. Introduction
Phenomena | Signs of Occurrence | Causes/Consequences |
---|---|---|
Wet stacking |
| Prolonged engine operation at a low load prevents the temperature from reaching its required value for the complete combustion of all the injected fuel. |
Polishing cylinder |
| Local mechanical friction is probably due to carbon deposits around the rings caused by poor combustion from running the engine at a low load. |

6. Conclusions
- Very low load.
- Low load.
- Medium load.
- According to data analysis, it is found that under a very low load (0–25%), the exhaust gas temperature does not exceed 190 °C for an extended period of operation (up to 2 h), while under a 30% load, the temperature stabilizes at 220 °C; this is true for both regimes (extended period and not extended period). Therefore, it was concluded that the exhaust gas temperature could be used as an index of underperformance operation if prolonged operation time under low load is associated.
- The BSFC showed an increase when the diesel–electric generator was subjected to a light load (≤30%) for a prolonged duration (up to 2 h) versus a short period (15 min). It recorded a 6.4 gallons/kWh consumption in underperformance operation at 30% of the applied load versus 6.14 gallons/kWh in normal operation. However, the BSFC returns to normal when the load attains 40% and registers 8.5 gallons/kWh. Based on the results obtained, the BSFC can be considered an underperformance index.
- Analysis of gas emissions such as carbon monoxide and sulfur dioxide emissions have been discarded. This could be explained by the fact that some emission values are similar under low and normal loads.
- Carbon dioxide emissions, nitrogen oxide emissions, and sulfur showed an increase in their levels when the generator was subjected to low load (≤30%) for a prolonged period (up to two hours) associated with underperformance operation. These gases tend to reach a normal emission level when the applied load increases to 40%. It was found that carbon dioxide emissions increase up to 0.5% under very-low and low loads (0–30%), nitrogen oxide emissions by up to 10 ppm, and sulfur by 2 ppm.
- Finally, unlike all other gases, oxygen emissions decrease under very-low and low loads by up to 2% before reaching the normal level of emissions under a normal load (40% and above). This allows us to conclude that oxygen can be also considered an underperformance index.
