    摘要: A method for controlling an engine having both an electronically controlled inlet device, such as an electronic throttle unit, and an electronically controlled outlet device, such as a variable cam timing system is disclosed. The method of the present invention achieves cylinder air charge control that is faster than possible by using an inlet device alone. In other words, the method of the present invention controls cylinder air charge faster than manifold dynamics by coordination of the inlet and outlet device. This improved control is used to improve various engine control functions.

    摘要: A vacuum actuated valve uses a specially designed spring having a spring rate as a function of valve position. The spring rate function is determined using physical relationships between flow, pressure, and valve s position. The result is that the relationship between the control input to the valve (either a vacuum signal, or an electrical signal to a vacuum source) and the flow through the valve are linearly related through the entire operating region of the valve.
