NiYo Engineers’ PC Based Engine Test Rig is designed for students to perform various tests on an IC Engine on a computerised system. This is an advanced state of the art training system. The IC engine and dynamometer are mounted on a rigid frame structure. The coupling is secured and has a safety cover. Instrumentation and signal conditioning is provided to measure various parameters like, temperature, fuel consumption, air flow rate measurement, load, engine speed, etc. Testing can be carried out at various loads. The load on the engine can be varied remotely from the PC

A water cooled calorimeter is supplied to measure and prepare Heat Balance-sheet.

There is a facility to plot P-Theta and P-V diagram.

The training equipment can function without computer interface/software also. This is a very helpful feature in case where the training needs manual operation and noting of the readings or in a rare case of computer failure.

Topics covered are,

• To determine Brake Power
• To determine engine volumetric efficiency
• To determine engine brake thermal efficiency
• To determine engine specific fuel consumption
• Complete energy balance using exhaust gas calorimeter.
• Determining air-fuel ratios
• Morse Test
• P-Theta and P-V diagram
• Heat release rate

The software is Windows based user friendly. The software enables design/modification of the mimic diagram. The data acquired, the data analysed and its calculations can be viewed in a tabular and/ or graphical form. Various graphs can be viewed e.g. hTh. v/s fuel consumption, rpm v/s BP, etc. The test rig facilitates to print and download the acquired data for the further analysis and graph plotting. The software also permits printing of the various data/screens.
