Description

Realize intake and exhaust heat control device and the method for Gasoline Engine HCCI Combustion
Technical field
The present invention relates to a kind of petrol engine intake and exhaust thermal control system, relate in particular to a kind of intake and exhaust thermal control system of realizing Gasoline Engine HCCI Combustion.
Background technique
Adopt homogeneous compression burning (Homogeneous Charge Compression Ignition, HCCI) to have higher fuel economy and lower NO on the petrol engine XEmission potential.In order to realize the homogeneous compression burning of petrol engine, need to the fuel-air mixture in the cylinder be compressed near the high temperature of 1000K.Body is not being done larger change, keeping under the uniform-charge Otto-engine compression ratio condition, it is a kind of main path that realizes Gasoline Engine HCCI Combustion that engine charge is heated.Because engine exhaust has higher heat, thus utilize heat exchanger to realize the heat exchange of exhaust-air inlet, thus realize the lifting to Engine Inlet Temperature, cannot not become additionally energy consumption and realize a kind of more excellent scheme of Gasoline Engine HCCI Combustion.
U.S. Lawrence Livermore National Laboratory is adopting under the prerequisite of air intake pressurized to the temperature service hoisting in document SAE2000-01-2869, utilizes exhaust-air inlet heat exchanger to satisfy the needs of HCCI burning to intake temperature.This system rely on the one hand that air intake pressurized brings temperature increase, this cover pilot system can't be accomplished the quick adjustment of intake temperature on the other hand, namely can't realize the running of HCCI engine burning transient state variable working condition.U.S. Ford Motor Company adopts exhaust-air inlet heat exchange to promote intake temperature in document SAE2002-01-2832, SAE2006-01-1082 and patent US6675579-B1, US2006150952-A1, and the modification engine aspirating system makes it to possess hot and cold two admission lines, by hot and cold two bursts of air inlets are mixed before entering cylinder in proportion, to obtain required intake temperature, finally realize the HCCI burning.But because the exchange capability of heat of exhaust-air inlet has been subject to the lower restriction of gas-to-gas heat exchanger efficient, in the actual tests process, can run into the problem that the heat exchange heat is difficult to satisfy air inlet temperature rise demand, must adopt Electric heating appliance to come the service hoisting intake temperature.In addition, the hcci engine of the above-mentioned Ford that mentions has adopted unconventional, higher compression ratio, also is in order to solve to a certain extent heat exchange shortage of heat heating air inlet to temperature required contradiction.Sweden Lund university is in SAE document 2004-01-0943, aspect the research of Gasoline Engine HCCI Combustion, built and U.S. Ford Motor Company similar exhaust-air inlet heat management system, also be that expectation utilizes the heat exchange of exhaust-air inlet to realize heating to engine charge, but having run into equally the hypodynamic problem of heat exchanger heat-energy transducer, also is to have adopted Electric heating appliance to promote intake temperature in the test of reality.
Can find out with the research situation that realizes Gasoline Engine HCCI Combustion from present employing exhaust-air inlet heat exchange, under the petrol engine compression ratio of routine, Gasoline Engine HCCI Combustion is to the high requirements of intake temperature, and the heat exchange efficiency of exhaust-air inlet heat exchanger has been proposed higher requirement.Be illustrated in figure 1 as engine operation when the HCCI pattern, attainable intake temperature and the schematic representation of realizing the intake temperature that the HCCI burning is required after petrol engine delivery temperature, the heat exchange.As can be seen from Figure 1, when the medium and small load of petrol engine, particularly when little load, the delivery temperature of motor is lower, and realize that the required intake temperature of HCCI combustion mode is high all the better, conventional heat exchanger is difficult to so that the intake temperature after the heat exchange satisfies the HCCI burning to the requirement of intake temperature; And in petrol engine during high load, the delivery temperature of motor is higher, realizes that the temperature requirements of HCCI burning is lower, so also have more surplus after exhaust gas heat and the air inlet heat exchange.Can find out from the above analysis, then must make intake temperature all satisfy the intake temperature demand of HCCI burning in various operating modes if want so that petrol engine is realized the HCCI burning under full operating mode.And when the lower small load condition of delivery temperature, even under the service hoisting effect of cooling water-air inlet heat exchange to intake temperature, also must make exhaust-air inlet heat exchanger reach high exchange capability of heat and could satisfy petrol engine and realize the HCCI burning.And gas-to-gas heat exchanger itself just exists the lower shortcoming of heat exchange efficiency, the optimization of heat exchanger structure parameter is difficult to significantly promote its heat exchange efficiency, also can bring simultaneously the negative effects such as gas-flow resistance rising, size increase, such contradiction has just caused exhaust-air inlet heat exchanger to be difficult to be applied to Gasoline Engine HCCI Combustion.
