Description
Technical field
The present invention provides a kind of internal-combustion engine and controlling method that has heat recovery and utilize function, is specifically related to a kind of exhaust heat recovery and utilization, fuel supply and burning control of internal-combustion engine.
Background technique
Since the seventies in 20th century, along with electronic technology and exhaust aftertreatment broad application, the oil consumption and the hazardous emission of internal-combustion engine are reduced significantly.Traditional petrol engine belongs to the premix homogeneous combustion, owing to receive the restriction of many factors such as pinking, compression ratio is low, and the thermal efficiency is low, adopts electronic control and exhaust gas post-treatment device can make petrol engine reach lower discharging.Compare with petrol engine, the diesel engine compression ratio is high, has the higher thermal efficiency and superior fuel economy, and still, the burning of conventional diesel engine is the diffusive combustion of injected fuel spray, and the high temperature when relying on internal combustion engine to be compressed near terminal point makes the mixed gas involuntary ignition.Because spraying is very short with the mixed time of air, it is seriously inhomogeneous that fuel and air mix, and forms high temperature rich mixture district and hot flame district, causes soot and NO
XThe a large amount of generation adopt Electrocontrolled high-pressure common rail and oil spout repeatedly technological and attach with exhaust gas aftertreatment techniques and can make diesel engine reach very low discharging, but cost is higher.Another kind receives the burning form of extensive concern, combines the high compression ratio of diesel engine and the premixing of petrol engine homogeneous, has formed homogeneous premixing ignition engine, and high compression ratio realizes high thermal efficiency, and the homogeneous premixing realizes low emission.This internal-combustion engine is at the mixed gas of intake process formation homogeneous, and homogeneous charge is realized the multiple spot involuntary ignition in the time of near being compressed to top dead center.Owing to adopt the weak mixture homogeneous to burn simultaneously, there is not localized hyperthermia's reaction zone of spark ignition and diffusive combustion, make NO
XVery low with the PM discharging, and have the higher thermal efficiency.Boundary conditions and chemistry of fuel Collaborative Control but this combustion manner is burnt do not have the spark ignition of petrol engine and the cylinder-in oil-jet of diesel engine to control ignition timing, therefore; Ignition timing is restive; Low-load is prone to catch fire, and high load is prone to pinking, and operating conditions is narrower.The conventional gasoline machine adopts stoichiometric proportion burning and mechanical throttle adjustment air inflow; The thermal efficiency when sub load is lower, delivery temperature is higher, the air inlet flow losses are big; Because petrol engine overwhelming majority time services are at part load condition, thereby cause the petrol engine overall thermal efficiency lower.The present invention adopts high-performance heat exchanger to reclaim the exhaust energy that internal-combustion engine is in part load condition; Utilize this energy that the air inlet of petrol engine is heated, can enlarge the lean-burn boundary of petrol-air mixture, realize efficient lean combustion; And in order to keep the power of former machine; Need open the engine, cause the pumping loss of petrol engine to reduce, therefore; Adopting air inlet heating, lean-burn and big throttle opening can improve the thermal efficiency and the reduction discharging of petrol engine in sub load greatly, is a kind of technological means of effective ignition internal combustion engine energy-saving and emission-reduction.
