Analysis of the Influence of Disturbance of Vacuum Stream Signal on Steering Process of the Spark-ignition Combustion Engine

This paper shows the results of research which consider the influence of vacuum signal disturbance on the steering process of combustion engine. It also presents design guidelines for installations of vacuum signal between suction manifold and vacuum sensor. Diagnostic analysis was made with the use of three-dimensional fuel charge map. Additionally, the paper shows the overview of causes of the disturbance of vacuum stream signal depending on the construction of the system and its operation.
