Type of Loading

Electric Brake Dynamometer

The engine is coupled with electrical alternator with resistance loading arrangement. Digital voltmeter and digital ammeter is provided.

Hydraulic Brake Dynamometer

It consist of weighing gear, control gear, a dead weight in Kg unit suitable for testing the engine at different speeds. The engine and dynamometer are directly coupled on a substantial base plate.               

Fuel measuring system 

Fuel measuring system consists of a fuel tank, a burette and a three way cock arrangement.

Air intake measuring system

Air tank fitted with orifice and water manometer.

Measurement of Heat carried

It consists of inlet outlet piping with flow control valve, water away by Cooling water meter. Thermometers are provided to measure the inlet outlet temperature of water.


Exhaust gas calorimeter

Exhaust gas calorimeter - made of Stainless Steel including the body & the tubes for cooling water circulation and designed to get maximum temperature difference. The body of the calorimeter is insulated on all sides to prevent heat losses due to radiation. Thermometers are provided to measure the temperature of water and gas.
