Description
Technical field
The present invention relates to a kind of engineering machinery waste gas cleaning system, relate in particular to a kind of engineering machinery engine particulate
The load of regeneration loads and energy-recuperation system.
Background technique
Diesel engine is because of good and economic, power character, reliability and lower CO, HC discharging, by extensive
Be applied to engineering machinery field, its domestic and international recoverable amount rises year by year, but the particulate of diesel engine (PM,
Particulate Matter) the discharging relatively serious 30-80 of petrol engine (be approximately doubly).In order to administer the environment dirt
Dye and protect human health, satisfy more and more stricter Abgasgesetz, must the particle emission of diesel engine be carried out
Control.
At present, the discharging of particulate matter (PM) is a high-performance environment-friendly diesel engine of new generation in the control diesel engine vent gas
One of key issue that need overcome will be so will become through exhaust aftertreatment mode reducing diesel engine particle emission
Essential, particulate filter (DPF) will be the control diesel particulate emission the most effectively, before the development of tool
One of means of scape, so motor producer adopts this technology one after another.Particle trapper mainly is earlier to tail gas
In the particulate that carries carry out trap filter, particulate is stacked into carries out Regeneration Treatment to catcher after a certain amount of again, with
Reduce its influence to diesel engine performance.
Adopting the dpf regeneration method that certain inferior position is arranged, is exactly specifically when idling and low-load work, by
In the back pressure that has improved motor, increased the consumption of fuel oil.In addition, under many occasions, load is not
