What are the solutions for Cummins diesel engine exhaust?
1 Answers
Cummins diesel engine exhaust solutions: Improve diesel ignition performance: Enhancing diesel ignition performance can make diesel combustion easier and more complete. The indicator for measuring diesel ignition performance is the cetane number. Adding alkyl nitrate to diesel can rapidly dissociate in the cylinder, producing active radicals. At a volume fraction of 0.1%, it can increase the cetane number by 1-6 units, thereby improving diesel ignition performance and effectively reducing particulate emissions. Additionally, low-sulfur fuel significantly impacts the performance and lifespan of exhaust after-treatment systems. Improve the fuel supply system: Reducing the injection advance angle moderately can decrease the amount of diesel in the cylinder during the rapid combustion phase, lowering the maximum combustion temperature of the mixture and thus reducing emissions. However, excessive delay in injection can increase smoke emissions from the diesel generator, leading to a decline in its power performance and fuel economy.
