Speed Control System

Spark ignition engines perform with low power efficiency and low fuel economy for which the throttling loss is the main reason. This paper introduces a new kind of intake control system-series valve speed control system that consists of two intake valves connected in series. It is operated without throttle to reduce the engine intake loss and thereby improve fuel economy under medium- and low-load working conditions. Through experiments, we confirm that compared with the basal spark ignition engine, the spark ignition engine with series valve speed control system can reduce fuel consumption, and the maximum fuel consumption rate can be increased up to 12% at the engine speed of 3000 r/min.

Existence Conditions

An optimal multi-input multi-output (MIMO) discrete integral variable structure control (DIVSC) rule is proposed in this paper. This approach can achieve accurate and robust dynamic responses. The modified existence conditions are introduced to assure the existence of the discrete non-ideal sliding motion. The design procedures are clearly developed in this paper. Use optimal LQ method to decide the coefficients of the sliding surfaces and integral gains. On the basis of the nonideal sliding motions, the control functions can be found out to satisfy the modified existence conditions. The idea of boundary layer is used to smoothing the control functions. Furthermore, take the engine idle speed control as an example. Simulation results will demonstrate the potential of the proposed approach.
