Tesca Auto Sci-Cal Engine Cycle Analyzer Module AMECA is a module with hardware and software to measure internal combustion engine cylinder pressure and crank angle.
Tesca AutoSci-Cal Engine Cycle Analyzer Module AMECA is a versatile module consisting of both hardware and software specially designed for educational use. It enables students to investigate the relationship between crank angle or volume and the cylinder pressure in an internal combustion engine. The equipment is primarily for use with engine test sets and engines but it can also be used with other engines fitted with compatible cylinder head transducers and crank angle encoders.
The equipment consists of a hardware unit with connectors and leads, plus Windows based data acquisition and analysis software. The hardware consists of a microprocessor-based signal conditioning unit with high-speed PC interface, housed in a rugged, protective enclosure. It accepts and conditions signals from the Cylinder Head Pressure Transducer and Crank Angle Encoder, pre-mounted on the engines. The cylinder pressure input includes a precision charge amplifier with a digital calibration. Crank angle position, the signal from the Crank Angle Encoder is also used to determine engine speed.
The output from the hardware unit connects to a computer (computer not included) running the Engine Cycle Analyser software. The hardware unit includes LED indicators to show the processor readiness, encoder top deadcentre position and PC communication status.
The software provides real-time display of pressure versus crank angle (p-q) and pressure versus volume (p-V) plots.
It performs calculations on the data to accurately display indicated mean effective pressure (IMEP) and indicated power for comparison with brake mean effective pressure (BMEP), and brake power to determine the mechanical efficiency of the test engine.
The software has useful snap-shot, replay and animation functions to help students visualise and better understand the engine cycle. The snap-shot and replay allow students to capture several engine cycles and study them using an animation showing the relative position of the crank, piston, inlet and exhaust valves. The software also allows students to create and recall engine configuration files for convenient entry of test engine data needed for calculations such as crank radius and engine swept volume. Data can also be exported to other software for further analysis.
