Definitions
- the invention relates to a device for controlling the residual gas content of individual cylinders of an internal combustion engine having a plurality of cylinders with mechanically fully variable valve train and throttle-free load control and in particular a rigid valve train on the outlet side.
- the residual gas content i. the amount of exhaust gas remaining in the individual cylinders is clearly controlled by the timing and valve lift on the exhaust side.
- the amount of residual gas left in the cylinders after closing the change-over valves is different for small outlet spreads.
- the amount of residual gas in the cylinder affects the ignition timing and the combustion in the cylinder. If the residual gas content of individual cylinders is too high, then these cylinders can not be ignited in terms of fuel consumption. The fuel consumption of such an internal combustion engine is then not optimal.
- Firing sequence are shifted, for cylinders, which are operated with low charge or with a small valve lift, based on the charge too high amounts of residual gas. These cylinders can no longer or no longer optimally ignited.
- a variable valve train of a reciprocating internal combustion engine with a controller for cyclically synchronous and preferably cylinder-selective switching of spark ignition in a controlled auto-ignition and vice versa wherein a valve group of a cylinder has a plurality of inlet and outlet valves and an opening duration of the valve group the inlet and / or outlet valves are divided differently, so that in the valve group of the cylinder, a valve is normally controlled in a partial load and another valve is used in particular for an internal exhaust gas recirculation.
- the invention has for its object to provide a device for controlling the residual gas content of individual cylinders of an internal combustion engine with multiple cylinders with mechanically vollvariablem valve train and throttle-free load control, especially at small Auslasssp Dahl Institute and throttle-free load control the residual gas content of the individual cylinder To optimize internal combustion engine with multiple cylinders and thereby optimize fuel consumption.
- the invention proposes a device in which an exhaust camshaft has an asymmetrical arrangement of cams, wherein the angle of rotation of the cams of individual special cylinders on the exhaust camshaft for adjusting the residual gas content is provided such variable that an exhaust spread at cylinders with too high Residual gas content is reduced or an outlet opening time of the individual cylinders is adjusted so that sets the same amount of residual gas in all cylinders.
- an internal combustion engine with throttle-free load control is operated via the mechanically fully variable inlet valves, the optimum consumption is achieved with a small outlet spread and a short intake control time with a small valve lift and small spread.
- the amount of residual gas that remains in the individual cylinders in such an internal combustion engine depends primarily on the exhaust valve spread and on the gas pressure ratio via the exhaust valve.
- the Gasd Weglor are not the same depending on the firing order on all cylinders and thus obtained with the same Auslass Kunststoffgeberzeit different levels of residual gas contents in the individual cylinders.
- the outlet spread is increased until an equal residual content in all cylinders is established.
- An advantageous variant is that the outlet opening time of the individual Cylinder is adjusted so that sets the same amount of residual gas in all cylinders.
- the exhaust valves of the individual cylinders are generally controlled with the same actuators and the same cam contours of the cams.
- the cams of the exhaust camshafts are provided by a firing interval corresponding to the firing order by the same or a multiple amount of the firing interval against each other rotatable.
- the angle of rotation of the cams of special cylinders on the exhaust camshaft to adjust the residual gas content is changed.
- the exhaust valves are equipped with different actuators.
- the valve lifts and the opening times of the exhaust valves are variably provided. It is advantageously provided that the exhaust camshaft has a cam arrangement in which the cams of the individual cylinders are not rotated by the same angle, or that the cam contours of the cams of the exhaust camshaft of the individual cylinders are different.
- the opening times of the cam of the exhaust camshaft are different, or that the valve strokes of the exhaust valves are different but the opening times are the same.
- individual cylinders or groups of cylinders may be completely decommissioned by keeping the intake and exhaust valves of these cylinders closed while opening the valves of the active cylinder or cylinder groups.
- Such internal combustion engines can be operated on the inlet side with a mechanically fully variable valve train in which the valves of individual cylinder groups are opened differently and the load of the internal combustion engine over the valve lift or the opening time is set.
- the exhaust valves are usually equipped with a switching valve drive, which switches the valves of the deactivated cylinder to a valve lift zero, while the exhaust valves of the active cylinder are fully opened. All cylinders are equipped with the same changeover levers, the same actuators and the same valves, valve springs, etc.
- the bearing diameter of the exhaust camshaft are provided differently and that in a 4-cylinder internal combustion engine with two exhaust cams, in particular a cam has a shortened control time with reduced valve lift.
- FIG. 1 shows a device for controlling the residual gas content of cylinders of an internal combustion engine in an overall view
- 2 shows an exhaust camshaft as a single part
- 3 is a diagram showing the timing and valve lifts at throttle-free load control.
- Fig. 4 is a diagram showing the timing and valve lifts at throttle-free load control and cylinders with higher residual gas content.
- Fig. 5 is a diagram showing the timing and the valve strokes of the exhaust valves 1 and 2 on a cylinder
- FIG. 1 shows a device for controlling the residual gas content of individual cylinders of an internal combustion engine having a plurality of cylinders with mechanically fully variable valve train and throttle-free load control and a mechanically rigid valve drive on the outlet side, consisting of a
- Exhaust camshaft 1 which according to Figure 2 has an asymmetrical arrangement of cam 2
- the cams 2 of individual special cylinders on the exhaust camshaft 1 for adjusting the residual gas content have different cam structures 3 and are provided so rotatable that, as shown in Figure 3, at a Internal combustion engine with throttle-free load control and mechanically fully variable valve train for actuating the intake valves, an outlet spread 5 is reduced in cylinders with excessive residual gas content, or an outlet opening time 7 for individual cylinders is adjusted so that sets the same amount of residual gas in all cylinders.
- the outlet spread 5 is increased if the residual gas content of a cylinder for this cylinder is too high, in order thus to reduce the residual gas content.
- an internal combustion engine with throttle-free load control operated by mechanically fully variable intake valves so is an optimal consumption at a small outlet spread 5 and a short intake timing 8 with small Valve lift and small spread achieved.
- the diagram shown in Figure 3 shows the timing and valve lifts at throttle-free load control for intake and exhaust valves with the exhaust and inlet spreads 4,5,6, with a larger outlet spread 5 for cylinders with higher residual gas content occurs.
- the amount of residual gas remaining in the individual cylinders in such an internal combustion engine depends primarily on the exhaust spread and on the gas pressure ratio via the exhaust valve.
- the Gasd Weglor are not the same depending on the ignition sequence on all cylinders and thus occur at the same Auslass Kunststoffzeit 8 different levels of residual gas contents.
- the outlet spread 4 is increased so far until an equally large residual content is established in all cylinders.
- the exhaust valve spread is increased until an equal residual content in all cylinders is established.
- Figure 4 shows a diagram illustrating the timing and valve lifts at throttle-free load control and cylinders with higher residual gas content.
- the effect of the same residual gas content in all cylinders can also be achieved by adjusting the outlet opening time 7 of the individual cylinders so that the same amount of residual gas is established in all cylinders.
- individual cylinders or groups of cylinders may be completely decommissioned by keeping the intake and exhaust valves of these cylinders closed while opening the valves of the active cylinder or cylinder groups.
- Such internal combustion engines can be operated on the inlet side with a mechanically fully variable valve train in which the valves of individual cylinder groups are opened differently and the load of the internal combustion engine over the valve lift or the opening time of a cylinder group is set.
- the exhaust valves are usually equipped with a switching valve drive, which switches the valves of the deactivated cylinder to a valve lift zero, while the exhaust valves of the active cylinder are fully opened. All cylinders are equipped with the same switching levers, the same actuators, the same valves, valve springs, etc. It is also only the cylinders whose exhaust valves are switched to be equipped with levers and the exhaust valves of the cylinders that are not switched off or switched, with non-reversible levers. According to FIG. 1, these cylinders can be equipped with different actuating elements, such as, for example, roller drag levers, valves or valve springs, or with cams with individual cam contours and different cam base circles. FIG.
- FIG. 5 shows the valve lifts of two exhaust valves on a cylinder. These elevations are achieved, for example, by different contours of the cams 2 and 3 in FIG. By these different survey curves once the residual gas amount of individual cylinder is affected, but at the same time a twist is imposed on the cylinder inner flow, which increases the Restgasver Wegkeit. This allows greater Auslasssp Rudungen be driven and the charge cycle work or fuel consumption can be reduced.
- the invention is not limited to the embodiment, but is variable in the design of the actuators of the cams.
