摘要： The invention relates to a method for regulating the engine speed in multi-cylinder internal combustion engines in order to achieve, in a simple and cost effective way, a precise and rapid detection of the engine speed enabling a stable regulation of the motor at a constant speed when the speed changes periodically and temporarily. For this purpose, the time required for a fixed sequence of successively sampled pulses is measured continuously and used to form actual equidistant and non-corrected engine speed values (n). The number of successively sampled pulses is fixed on the basis of the number of the engine cylinders and the number of pulses that can be produced by the polar wheel each time it turns. In addition, the time required for a number of sampled pulses corresponding to a complete rotation of the polar wheel to be stored, is measured and used for producing a mean engine speed (N). The difference between the mean engine speed (N) and each actual uncorrected engine speed value (n) is smoothed for producing actual corrected engine speed values (x), said difference value is bound and then added to the actual non corrected engine speed (n). The actual corrected engine speed values (x) are compared to the predetermined value of the set speed engine (w) and transferred to a regulator (3) producing an output value (y) used for controlling the regulating means.

摘要： A control system is adapted for a direct injection engine (1) of spark ignition type provided with an exhaust gas purifying catalyst (11) in an exhaust passage (3), a fuel injection valve (5) for directly spraying fuel into a combustion chamber, a sparking plug (4) having an electrode projecting into the combustion chamber. The control system includes an intake air amount controller (18) for controlling the amount of intake air to be admitted into the combustion chambers, and a fuel injection controller (19) for carrying out stratified combustion in a stratified combustion region set in a low engine load region while carrying out uniform combustion in a uniform combustion region set in a high engine load region. When the intake air amount controller (18) executes a control to reduce the amount of intake air in the stratified combustion region when the engine (1) is warm, and the fuel control system advances the fuel injection starting timing within a compression stroke and sets a degree of advancement within such a range where stratified combustion can be maintained. Accordingly, deterioration of combustibility can be effectively prevented when the intake air amount controller (18) executes the control to reduce the amount of intake air in the stratified combustion region.

摘要： An idling control apparatus of an internal combustion engine which undergoes an after-start lean-burn control for operating the internal combustion engine at an air-fuel ratio on a lean side of a theoretical air-fuel ratio after the engine started. According to the apparatus, the engine rotational speed under the after-start lean-burn control at a low temperature is stabilized, fluctuation of the engine rotational speed at a time when a lean-burn control is canceled is restrained, and a smooth idling state is realized always.

摘要： Described is a method of controlling a non-linear-acting controlled system, the method calling for a variable indicative of the status of the system (5) to be determined and, using a control procedure and a reference value, a control value to be determined. In addition, making use of a parameter indicating the status of the system (5), a correction factor is read off a linearization characteristic (4) and multiplied by the control value, the product being used as a new reference value for control of the system (5). The linearization characteristic (4) is chosen in such a way that multiplication of the linearization characteristic by the non-linear control behaviour of the controlled system (5) gives linear control behaviour.

摘要： A single physical model which receives inputs of at least the intake pressure (31) and rotational speed (32) of an internal combustion engine (2) and which produces an output which controls an opening area of an intake passage (17) is developed for a controller (3) to control the idling speed or the output of the internal combustion engine on the basis of modern control theory. When the intake pressure is equal to or less than a predetermined value (critical pressure), the flow velocity of air which is sucked into a cylinder (4a) is fixed at sonic velocity, irrespective of changes in the level of the intake pressure, so the quantity of intake air is proportional to the opening area of the intake passage. Under these conditions, a manipulating quantity for controlling the opening area is determined by multiplying a control quantity outputted from the controller by a predetermined constant. On the other hand, when the intake pressure exceeds the critical pressure, the quantity of air flowing into the cylinder changes in accordance with the difference between the intake pressure and the atmospheric pressure. In that case a manipulating quantity is determined by compensating the control quantity in accordance with the pressure difference.
