Definitions
- the present invention relates to operation control of an internal combustion engine using an EGR (including an internal combustion engine having an NO x storage catalyst in an exhaust passage), and aims at stabilizing combustion.
- EGR including an internal combustion engine having an NO x storage catalyst in an exhaust passage
- EGR is often used in internal combustion engines (especially GHP engines) because high thermal efficiency can be obtained by using EGR when the engine load or engine speed is high.
- the GHP engine is the engine that drives the heat pump system.
- An object of the present invention is to provide an operation control method for an internal combustion engine that can obtain good thermal efficiency and achieve stable combustion at a low load. (How to solve it)
- the EGR rate is set to a minimum or zero at a low load.
- EGR is performed after the temperature of the exhaust gas is lowered by the heat exchanger.
- a predetermined load or less is set to a low load operation region.
- the thermal efficiency is set to a desired value by manipulating the excess air ratio and the EGR ratio according to the invention of claim 1 or 2.
- the operating range of the internal combustion engine 1 0 0 is to set the EGR rate at the time of low load to a minimum or zero ports, it is kept low concentration of NO x while maintaining a high thermal efficiency it can.
- the EGR rate can raise the exhaust temperature by setting the zero port, the regeneration of the NO x storage catalyst can be carried out quickly.
- FIG. 1 is a system schematic diagram of an internal combustion engine for carrying out the inventions of claims 1 to 6.
- FIG. 2 is a graph showing the relationship between the engine load of the internal combustion engine and P i V which is an index indicating the degree of combustion instability.
- Fig. 3 is a graph showing the area of transportation for shellfish using EGR and the area of optimal fre- quency without using EGR.
- FIG. 4 is a graph showing a vehicle ⁇ 1 region using EGR and a region ⁇ 5 where EGR is not used!
- FIG. 5 is a graph showing an operation area using EGR and an operation area not using EGR, which are different from those shown in FIGS. 3 and 4.
- FIG. 6 is a graph showing the relationship between the New Omicron chi concentration and thermal efficiency of the exhaust gas.
- Figure 7 is the EGR rate of 0% is a graph showing the 5% and 1 0% air at the time of setting the excess Well New Omicron chi amount of relationship.
- FIG. 8 is a graph showing the relationship between engine load and exhaust gas temperature.
- EGR rate is a graph showing the relationship between temperature and Nyu_ ⁇ ⁇ concentration in the exhaust gas (EGR gas) in the case of the non-zero.
- FIG. 1 is a system schematic diagram of an internal combustion engine 100 for carrying out the inventions of claims 1 to 6.
- a supply pipe 7, a fuel supply pipe 9, a mixer 8 for mixing air supplied from the supply pipe 7 and the fuel supply pipe 9 with a fuel gas, and a mixture supply pipe. 1 1 etc. are connected.
- the opening of the fuel supply amount adjustment valve 10 By adjusting the opening of the fuel supply amount adjustment valve 10, the fuel supplied to the mixer 8 The amount of air can be reduced by tl, the excess air ratio; I can be set arbitrarily. Also, by adjusting the opening of the throttle 12, the amount of air-fuel mixture supplied to the combustion chamber can be adjusted.
- An exhaust pipe 1 (exhaust passage) is connected downstream of the combustion chamber.
- the exhaust pipe 1 is provided with a NO x g storage catalyst 2 and a heat exchanger 6 in the order from the upstream side.
- the exhaust pipe 1, the mixture supply pipe 11, and the exhaust gas return pipe 3, which are further downstream from the heat exchanger 6, can communicate with each other. Therefore, a part of the exhaust gas can be made to flow into the mixture supply pipe 11 (or a mixture supply branch pipe (not shown) downstream thereof) through the exhaust gas return pipe 3. I have.
- a throttle valve 5 is provided in the exhaust gas return pipe 3.
- the opening of the throttle valve 5 can be adjusted by the CPU 4.
- the opening of the throttle valve 5 is reduced, the amount of exhaust gas flowing into the air-fuel mixture supply pipe 11 decreases. Conversely, increasing the opening will increase the inflow of exhaust gas.
- the EGR rate increases as the amount of exhaust gas flowing into the air-fuel mixture supply pipe 11 increases, and the EGR rate decreases as the amount of exhaust gas decreases. Therefore, increasing the opening of the throttle valve 5 increases the EGR rate, and decreasing the opening decreases the EGR rate.
- the CPU 4 adjusts the opening of the throttle valve 5 to set the EGR rate arbitrarily. You can do it.
- a plurality of sensors are provided in the internal combustion engine 100. With these sensors, information such as the engine speed of the internal combustion engine 100, the engine load, the coolant temperature, the ignition timing, the excess air ratio L, and the exhaust temperature are input to the CPU 4. .
- the CPU 4 has a memory in which an optimal combination map of the EGR ratio and the excess air ratio corresponding to the operation region is stored in advance. CPU 4 compares this map and the signal detected by the sensors, so stable combustion and good thermal efficiency One or suppressing the concentration of NO x upstream of the NO x storage catalyst is obtained, the throttle valve Change the opening of 5 and change the EGR rate.
- FIG. 2 is an index showing the engine load of the internal combustion engine 100 and the degree of combustion instability.
- the EGR rate is set to zero.
- the engine load as shown in FIG. 5 is P 2, P 3 or less and the engine speed, to set the EGR rate to zero in the operating area such that N 2 or less.
- the luck is described as "with EGR! In the ⁇ region, set the £ 01 rate to, for example, 5% to 15%.
- FIG. 6 is a graph showing the relationship between NO x concentration in exhaust gas and thermal efficiency.
- the thermal efficiency e when the thermal efficiency reaches e, the increase in thermal efficiency slows down, and after that, the thermal efficiency hardly increases compared to the increase in NO x amount. Therefore, the thermal efficiency e at this time is set to the upper limit, and the CPU 4 adjusts the opening of the throttle valve 5 so that the EGR rate required for obtaining the thermal efficiency e is obtained.
- FIG. 7 is the EGR rate of 0% is a graph showing the relationship between the 5% and the excess air ratio when set at 10% lambda and N Omicron chi amount. More vo chi amount EGR rate increases from FIG. 7 decreases, the air excess ratio I it can be seen that the vo chi amount enough becomes lean is decreased.
- FIG. 8 is a graph showing the relationship between engine load and exhaust gas temperature. As shown in Fig. 8, it can be seen that the exhaust temperature increases as the EGR rate is set lower.
- FIG. 9 is a graph showing the relationship between the playback speed of the exhaust gas temperature and vo chi occluding catalyst 2.
- Vo chi occluding catalyst 2 reaches the storage limit of vo chi, more can no longer be occluded, since it becomes impossible to perform cleansing of the exhaust gases, and Ritsuchi spike setting the excess air Ritsue to Ritsuchi An operation called is performed. This rich The spike, NO x occluded in the NO x storage catalyst 2 is reduced, storage capacity of the NO x storage catalyst 2 returns.
- Figure 10 is a graph showing the EGR rate than zero (i.e., throttle valve condition 5 is open) the relationship between the temperature and the concentration of NO x in the exhaust gas in-out Noto return pipe 3 in the favorite gas (EGR gas) It is.
- low load can be arbitrarily set in consideration of the operation performance of the internal combustion engine 100. For example, a load that is equal to or less than half the rated value can be set as “low load”.
- the present invention is applicable to land and marine internal combustion engines using EGR.
