Burner system
Active regeneration by Hybrid Burner system
The hybrid burner system has two operating modes depending on the engine running condition
Catalytic Burner Mode
- Fuel injected in front of pre-catalyst(DOC) when the exhaust temperature exceeds 250℃(in High Torque and High RPM condition)
- Flameless combustion(Exothermic reaction) process occurs
- Exhaust temperature can be increased up to 450℃ for FBC aided regeneration or up to 650℃ for O2 regeneration
Flame Burner Mode
- Fuel can be injected while the exhaust temperature is below 250℃(in Low Torque and Low RPM condition)
- Ignited by pre-heated glow plug and forms visible flame
- Exhaust temperature can be increased up to 450℃ for FBC aided regeneration or up to 650℃ for O2 regeneration
- Can be operated in low oxygen concentration until 12~14%
The hybrid burner system raise the exhaust temperature up to target temperature of 450℃ or 650℃ in any operation condition and successfully burn out accumulated soot in the filter.
Hybrid burner system can safely regenerate filters, and precisely controls the right timing for both Diesel burner and Catalytic burner.
