 IAV the KIS knock test system - the Knock Indication System 
 The IAV detonation test system (KIS) is an activity for engine knock, combustion characteristics of real-time monitoring and statistical evaluation of the measurement equipment. Real-time monitoring and evaluation of the activities of KIS system dedicated to engine knock, and powerful off-line statistical functions. Suitable for both bench and vehicle testing. Detonation test system (KIS) is a performance measurement system, which includes a set of hardware system and a set of analysis software. Knock control system, data processing and analysis, the user can objectively engine knock the activities of the technical indicators, coupled with the flexibility of the statistical analysis can drastically shorten the time of knock control system matching calibration, which cost savings. Detonation test system (KIS) has a pressure sensor and knock sensor input interface with external analog signal input port. KIS system built-in microprocessor can calculate the eigenvalue combustion engine, such as the maximum cylinder pressure, and online analysis of these eigenvalues. KIS systems with CAN communication interface, users can output to the measurement signal and the statistical characteristic values ??on the other measurement or control system, enabling the seamless connection between the systems.

 IAV KIS Software - Software, KIS 
 Applications 
 The KIS detonation test system with a set of high-performance analysis of the configuration software. Users of the software can be configured KIS hardware, establish communication with other devices, select the measurement signal line real-time display. The user can choose between two display modes: signal - periodogram or arbitrary signal correlation diagram, this feature is used for rapid evaluation of knock control / quality measurement system, very convenient. 
 In addition to the actual measurement signal, the KIS system real-time to calculate some statistical parameters of the detonation activities, such as detonation frequency detonation state and fire rate. In order to distinguish the knock and knock, the user can choose the critical value of pre-calibration or custom chart. The software and KIS hardware components of an effective knock detection, calibration of the analysis system.
