The SINPAR SXCP touch-screen octane panel with easy-to-follow guidance simplifies the fuel rating operation process.
Auto-Set Techniques
Auto-Settings for Intake Temperatures, Ignition Timing and C.R. Digital Counter (Cylinder Height). Manual adjustments for basic parameters are also available.
SXCP Professional Software
The SXCP Professional Software provides user-friendly interface and simple octane rating procedures of ASTM RON and MON test methods.
Automatic calculation and optimization system minimizes human errors and other failures. New operator requires less training to achieve proficiency.
SXCP Professional Software
Falling Level Program
Falling Level Program is used with four-bowl variable-level carburetor for determining maximum K.I. without manual adjustment of fuel level.
The operator can efficiently and accurately run a falling level test by PROCEDURE B in ASTM D2699 and ASTM D2700 Standards.
Falling Level Program
Electronic On-Board Barometer
Electronic On-Board Barometer is used for C.R. Digital Counter Correction as per ASTM method specifications.
Sensor-Measured Cylinder Height
The Cylinder Height is measured and adjusted automatically accurately by a specialized sensor-measuring and motor control system. The results are displayed in compensated and uncompensated readings that are recorded in the test report.
Electronic On-Board Barometer
Automated Digital Knock Meter
The Digital Knock Meter displays actual and accurate K.I. values and real-time waveform, thus realizes more consistent and reliable octane test results.
Meanwhile, the data and calculation results are recorded automatically to generate octane rating report.
Digital Knock Meter
Automated Data Recordings
The Data Recordings as well as octane rating reports including KI values, octane numbers, temperatures and pressures data, fuel level values and critical operating parameters, are automatically captured and presented in a PDF report. That can avoid human recording and calculating errors.
Report is easy to review, print and save.
Automated Data Recordings
More Safety System
The Safety System protects octane engine with full-system monitoring and E-stop, that ensures long service life and carefree operation.
More Safety System
Maintenance Logs
The Logs (including records of engine hours, cylinder hours, oil-change intervals and Maintenance/Service operation comments) can be displayed on screen for easy reference.
Maintenance time is regularly reminded.
