INTAKE MANIFOLD VALVE SYSTEM, METHOD, AND DIAGNOSTIC |
| 摘要 |
A valve control and diagnostic system uses physical stops to determine whether a connection between the valve motor and the valves has become degraded. The method can detect degradation in both the opening and closing direction, as well as in multi-valve systems, such as used on internal combustion engines.
