2 Elektrodyne Electrical Dynamometer Eddy current 200 EC 200 HP @ 3500 to 5500 rpm
3 BENZ Systems Eddy current ECB 300 M 300 HP @ 3000 to 5000 rpm

Raw Exhaust Gas Analysis System for diesel and CNG engines
The Raw Exhaust Gas Analysis System for diesel and CNG engines equipment provides facility to measure different constituents in raw exhaust gases, such as hydrocarbons, carbon monoxide, carbon dioxide, oxides of nitrogen and oxygen from engines.

The specifications of Raw Exhaust Gas Analysis System for diesel and CNG engines are

O2 Range 0 – 25% any 4 ranges selectable 0 – 1, 5, 10 and 25%

Mini Dilution Tunnel (partial flow dilution, total sampling) AVL Austria Model - SPC472 (2 Nos.
This tunnel is suitable to measure particulates from diesel engine, as per national and international standards, such as EEC 91/542, ISO 8178 and ECE R-49

Engine intake air conditioning unit
This mobile unit supplies air at reference atmospheric conditions (temperature, pressure. and humidity) to the engine intake as per regulations, such as CMVR, EEC 91 / 542, ECE R 49 and ISO 8178.

Engine test automation system
All the equipments in engine test cell such as dynamometer, dynamic fuel consumption meter, fuel and coolant conditioning unit, smoke meter, combustion air handling unit, raw exhaust gas analysis system and particulate measurement unit have been interfaced with the HOST computer. With automation system, it is possible to conduct the power, smoke (steady & transient) and emission measurement tests (steady state) in AUTO mode with the final result calculation and report generation.
