SUBSTANCE: in an inlet pipeline, at a small distance to an inlet valve of a cylinder there is a blowdown valve installed driven from a common cam shaft. In the end of an inlet stroke, 40-50° to the top dead centre (TDC), the inlet valve is opened. Spent gases go through the open inlet valve and reach the closed blowdown valve. Near the TDC, with remaining 10°, the blowdown valve is opened, and the combustion chamber is blown with air from an inlet header, afterwards the cylinder filling starts. Such solution makes it possible to substantially expand the angle of valves closure, this increasing the filling phase.

SUBSTANCE: invention considers spark ignition internal combustion engines. The internal combustion engine includes variable compression mechanism, the mechanism of valve timing adjustment, and throttle gate and catalyst and temperature predicative tool of the catalyst. Catalyst is placed in the outlet port of the engine. When engine load becomes lower, the mechanical compression degree increases to the maximum mechanical compression value and induction valve timing is shifted from the lowest dead point of induction given that the catalyst is active. If it is predicted that in case of load lowering the catalyst temperature will fall below activation temperature, then reduction of mechanical compression degree, shift value of induction valve timing in a direction to lower dead point of induction and reduction in degree of throttle gate opening becomes larger to lower the degree of actual expansion simultaneously with supporting or increasing the actual compression degree.

EFFECT: ensuring catalyst temperature increase at the same time maintaining good conditions for combustion initiation.

SUBSTANCE: invention considers spark ignition internal combustion engines. The internal combustion engine contains the variable compression mechanism (A) which allows changing the degree of mechanical compression, and the mechanism (B) of valve timing adjustment, which allows changing the induction valve timing (7). The volume of induced air supplied to the combustion chamber (5), is controlled by means of changing the induction valve timing (7). Degree of mechanical compression increases to the maximum degree of mechanical compression when the volume of induced air supplied to the combustion chamber decreases. In this case the volume of induced air supplied to the combustion chamber (5) decreases when the induction valve timing (7) is moved from the dead point of induction to the limit valve timing. When the induction valve timing (7) reaches the limit valve timing, the volume of induced air into the combustion chamber (5) becomes the limit controlled amount of induced air controlled by the valve timing adjustment mechanism. When the volume of induced air into the combustion chamber (5), decreases additionally due to the limit controlled volume of induced air, induction valve timing (7) is kept at the limit valve timing. During acceleration, when the volume of induced air into the combustion chamber (5) is less than limit controlled volume of induced air, if required acceleration degree is higher than predefined degree, movement of the induction valve timing (7) starts from the limit valve timing in the direction approaching to the lower dead point of induction when the volume of induced air to the combustion chamber is less in comparison with that when required acceleration degree is lower than predefined degree.

EFFECT: acceleration increase.

SUBSTANCE: proposed engine comprises variable compression ratio mechanism, variable phase distribution setter, and restrictor. With engine load decreasing, compression ratio increases to its maximum kept thereat in load zone lower than that of engine. Note here that intake valve closing setting displaces from BDC to maximum closing setting. With closing setting reaching maximum values, engine load is lower that load at which compression ratio reaches its maximum. Simultaneously, actual compression ratio downs gradually compared with engine high-load operation time. With intake valve closing setting reaches its maximum, amount of air intake is controlled by restrictor in the range of loads lower than that of engine whereat intake valve closing setting reaches its maximum. At loads lower the engine load when intake valves closing setting reaches its maximum, restrictor may be retained in completely open position.

SUBSTANCE: internal combustion engine (ICE) with spark ignition includes regulated gas distribution phase mechanism, variable compression degree mechanism and throttle valve. Throttle valve is arranged in inlet ICE channel. When ICE load decreases from high to low, the closing moment of inlet valve is moved in the direction from lower dead inlet point. At low load operation of the engine the mechanical compression degree is kept maximum. At high load operation of the engine, the mechanical compression degree increases when the engine load becomes lower; at that, actual compression degree remains constant. Pre-determined load is set within the range of load where mechanical compression degree is kept maximum. Throttle valve is retained in fully opened state in the area between high and pre-determined (L2) loads. When engine load becomes lower, the opening degree of throttle valve becomes lower and opening moment of inlet valve moves in the direction from upper dead inlet point. In the load area, where mechanical compression degree is kept maximum, actual compression degree becomes lower when the engine load decreases.

SUBSTANCE: internal combustion engine (ICE) with spark ignition includes compression degree control mechanism, gas distribution phase control mechanism and throttle valve. When load on ICE becomes lower, the closing moment of inlet valve is shifted aside from lower dead point of suction stroke, and mechanical compression degree increases to maximum. At engine operation in range of loads that are lower than engine load at which mechanical compression degree becomes maximum, mechanical compression degree is maintained as maximum load, and actual compression degree decreases. On engine operation side with high load the mechanical compression degree decreases gradually when the load increases. When engine load becomes lower, inlet valve is shifted from lower dead point of inlet stroke. When engine load decreases on engine operation side with low load, actual compression degree decreases; at that, throttle gate closes.

SUBSTANCE: internal combustion engine (ICE) with spark ignition includes regulated gas distribution phase mechanism, variable compression degree mechanism and throttle valve. Regulated gas distribution phase mechanism has the possibility of regulating the setting of inlet valve closing moment. Variable compression degree mechanism has the possibility of changing mechanical compression degree. At negative pressure in ICE inlet valve, which is lower than the required negative pressure, throttle valve opening degree is set to lower value. At lower throttle valve opening degree in the inlet valve there shall be set the required negative pressure or bigger negative pressure. At setting of the required or bigger negative pressure in inlet valve the setting of closing moment of inlet valve shifts in the direction close to lower inlet dead-point. Volume of intake air, which corresponds to the engine load, is supplied to combustion chamber in compliance with throttle valve opening degree. At that, mechanical compression degree is set to lower value in order to reduce the pressure at the end of compression.
