Any crank angle within the range can be set.
- variable valve timing mechanism B shown in Fig. 1 and Fig. 4 shows an example.

- Figure 6 (B) explains the actual compression ratio.
- Figure 6 (C) illustrates the expansion ratio.
- FIG. 7 shows the relationship between the theoretical thermal efficiency and the expansion ratio
- FIG. 8 shows a comparison between a normal cycle and an ultra-high expansion ratio cycle that are selectively used according to the load in the present invention.
- Fig. 8 (A) shows the normal cycle when the intake valve closes near the bottom dead center and the compression action is started from the piston near the bottom dead center.
- Fig. 8 (A), (A), (B) shows the normal cycle when the intake valve closes near the bottom dead center and the compression action is started from the piston near the bottom dead center.
- the combustion chamber volume is 50 ml
- the piston stroke volume is 50 ml.
- the actual compression ratio is almost 11
- the solid line in Fig. 7 shows the change in theoretical thermal efficiency in the normal cycle when the actual compression ratio and expansion ratio are almost equal.
- the theoretical thermal efficiency increases as the expansion ratio increases, that is, as the actual compression ratio increases. Therefore, in order to increase the theoretical thermal efficiency in the normal cycle, the actual compression ratio should be increased.
- the actual compression ratio can only be increased to a maximum of about 12 due to the restriction of the occurrence of knocking during high engine load operation, and therefore the theoretical thermal efficiency must be sufficiently high in the normal cycle. I can't.
- the present inventor has studied to increase the theoretical thermal efficiency by strictly dividing the mechanical compression ratio and the actual compression ratio. As a result, the theoretical thermal efficiency is governed by the expansion ratio. Thus, the actual compression ratio was found to have little effect. That is, if the actual compression ratio is increased, the explosive force increases, but a large amount of energy is required for compression, and thus the theoretical thermal efficiency is hardly increased even if the actual compression ratio is increased.
- FIG. 8 (B) shows an example of using the variable compression ratio mechanism A and variable valve timing mechanism B to increase the expansion ratio while maintaining the actual compression ratio at a low value.
- variable compression ratio mechanism A reduces the combustion chamber volume from 50 ml to 20 ml.
- variable valve timing mechanism B delays the closing timing of the intake valve until the actual piston stroke volume is reduced from 500 ml to 200 ml.
- the actual compression ratio is almost 11 and the expansion ratio is 11 as described above. Compared to this case, the expansion ratio is higher in the case shown in Fig. 8 (B). It can be seen that only is raised to 26. This is why it is called an ultra-high expansion ratio cycle.
- the lower the engine load the worse the thermal efficiency. Therefore, in order to improve the thermal efficiency during engine operation, that is, to improve fuel efficiency, improve the thermal efficiency when the engine load is low. Is required.
- the ultra-high expansion ratio cycle shown in Fig. 8 (B) the actual piston stroke volume during the compression stroke is reduced, so the amount of intake air that can be drawn into the combustion chamber 5 is reduced.
- the ultra-high expansion ratio cycle can only be adopted when the engine load is relatively low. Therefore, in the present invention, when the engine load is relatively low, the super high expansion ratio cycle shown in FIG. 8 (B) is adopted, and during the engine high load operation, the normal cycle shown in FIG. 8 (A) is adopted.
- Figure 9 shows the mechanical compression ratio according to the engine load at a certain engine speed, Changes in the expansion ratio, the closing timing of the intake valve 7, the actual compression ratio, the intake air amount, the opening of the throttle valve 17 and the bombing loss are shown.
- the average in the normal combustion chamber 5 so that the unburned HC, CO and NO x in the exhaust gas can be simultaneously reduced by the three-way catalyst in the catalyst converter.
- the air-fuel ratio is feedback controlled to the theoretical air-fuel ratio based on the output signal of the air-fuel ratio sensor 21.
- the normal cycle shown in FIG. 8 (A) is executed during engine high load operation. Accordingly, as shown in FIG. 9, the expansion ratio is low because the mechanical compression ratio is lowered at this time, and the valve closing timing of the intake valve 7 as shown by the solid line in FIG. 9 is as shown by the solid line in FIG. It has been expedited. At this time, the intake air amount is large, and at this time, the opening degree of the throttle valve 17 is kept fully open or almost fully open, so that the bombing loss is zero.
- the mechanical compression ratio is increased as the intake air amount is decreased while the actual compression ratio is substantially constant. That is, the volume of the combustion chamber 5 when the screw 4 reaches the compression top dead center is reduced in proportion to the reduction of the intake air amount. Therefore, the volume of combustion chamber 5 when piston 4 reaches compression top dead center The product changes in proportion to the amount of intake air.
- the air-fuel ratio in the combustion chamber 5 is the stoichiometric air-fuel ratio
- the volume of the combustion chamber 5 when the piston 4 reaches the compression top dead center changes in proportion to the amount of fuel. It will be.
- the mechanical compression ratio is further increased.
- the mechanical compression ratio reaches a limit mechanical compression ratio that is the structural limit of the combustion chamber 5.
- the mechanical compression ratio is maintained at the limit mechanical compression ratio in a region where the load is lower than the engine load when the mechanical compression ratio reaches the limit mechanical compression ratio. Therefore, the mechanical compression ratio is maximized and the expansion ratio is maximized when the engine is under medium load operation on the low load side and during low engine load operation, that is, on the engine low load operation side. In other words, the mechanical compression ratio is maximized so that the maximum expansion ratio can be obtained on the engine low load operation side, while the embodiment shown in FIG.
- FIG. 9 shows a solid line in FIG. 9 regardless of the engine load.
- the closing timing of the intake valve 7 is delayed as the engine load decreases.
- a predetermined load L 2 is set in the load region where the mechanical compression ratio is maintained at the maximum mechanical compression ratio, and the opening degree of the throttle valve 17 is When the engine load is lower than the predetermined load L 2, it becomes smaller as the engine load becomes lower.
- the throttle valve 17 is kept fully open.
- the intake air amount into the combustion chamber 5 can also be controlled by controlling the closing timing of the intake valve 7, and can also be controlled by controlling the opening degree of the throttle valve 17. .
- controlling the intake air amount into the combustion chamber 5 by controlling only the closing timing of the intake valve 7 is effective as the engine load decreases.
- the compression ratio will decrease.
- the actual compression ratio decreases in this way, the temperature in the combustion chamber 5 at the compression end decreases, and as a result, the ignition and combustion of the fuel deteriorate.
- the closing timing of the intake valve 7 is controlled to control the inside of the combustion chamber 5.
- both the closing timing of the intake valve 7 and the opening of the throttle valve 17 are controlled to control the intake air amount in the combustion chamber 5. The amount of intake air to the is controlled.
- variable compression ratio mechanism ⁇ is formed so that the expansion ratio is 20 or more.
- the intake air amount can be controlled without depending on the throttle valve 17 by increasing the closing timing of the intake valve 7 as the engine load decreases. Accordingly, in the embodiment according to the present invention, when the solid line and the broken line in FIG. 9 are both included, in the embodiment according to the present invention, the engine load becomes low when the intake valve 7 is closed. As a result, it is moved away from the intake bottom dead center BDC.
- FIG. 10 shows the operation control routine.
- the target actual compression ratio is calculated.
- the closing timing I C of the intake valve 7 is calculated from the map shown in FIG. 11 (A). That is, as shown in Fig. 11 (A), the closing timing IC of the intake valve 7 required to supply the required intake air amount into the combustion chamber 5 is a function of the engine load L and the engine speed N.
- the map is stored in advance in the ROM 32, and the valve closing timing IC of the intake valve 7 is calculated from this map.
- the mechanical compression ratio CR is calculated.
- the opening of the throttle valve 17 is calculated. This The opening 0 of the throttle valve 17 is stored in advance in the ROM 3 2 in the form of a map as shown in FIG. 11 (B) as a function of the engine load L and the engine speed N.
- the variable compression ratio mechanism A is controlled so that the mechanical compression ratio becomes the mechanical compression ratio CR, and the variable valve evening mechanism so that the closing timing of the intake valve 7 becomes the closing timing IC.
- B is controlled, and the throttle valve 17 is controlled so that the opening degree of the throttle valve 17 becomes zero.
