System for regulating IC engine with gas changing valves with variable control for variable adjustment of combustion air amount to be supplied with throttle operable independent of valves with regulating-control unit

摘要

The system is designed so that with the failure to reach the reference pressure in the regulating and control valve, a control signal activates the throttle unit in the engine suction pipe, and with the exceeding of the reference pressure in the regulating and control valve, at least one control signal is producible, activating a gas exchange valve. The actual accelerator setting is assigned a desired air mass (L soll,O) and a desired pressure (P soll,O P soll,k). The desired pressure is compared with a reference pressure (P a). With the failure to reach the reference pressure, the control of the desired air mass results across the throttle unit in the engine suction pipe. The exceeding of the reference pressure results in the control of the desired air mass across the gas change valves.
