This dyno can take Tandem Axle vehicle for testing which has distance of 1.3 m to 1.8m in driven axles
In this facility, all EV-HEV vehicles/ buses, Diesel , CNG, LPG, LNG, flexi fuel etc., development work can be taken to cater todays customer’s need
In this temperature controlled test cell at ARAI Kothrud, Exhaust gas Emission Measurement system for CO, HC, NOX, CO2, Fuel consumption and PM using PEMS
Electric Vehicle Range test, energy consumption and various development test can done . Charger for these vehicles is installed in HCV
A 100kW resistive 2 Nos. load banks was recently added to the setup to increase the test cell’s operating temperature to 50 degrees Celsius. Due to this hot summer trials for Engine calibrations on HCVs can be performed on this chassis dynometer.
