Stiffer Unit Cam Shaft
Other action taken to promote use of Bio-Diesel in Indian Railways is as under:
Following future action plan has been made to measure and reduce Emissions:
Results of Emissions and Particulates measurements made for 16 cylinder EMD 4000 HP engine in 2001:
Uncontrolled effluents of diesel sheds have an impact on the environment. Following work has been done to achieve the above:
The following two fuel efficiency indices are popularly used on Indian Railways:
Fuel Consumption on 8th Notch
Fuel consumption at this notch is one of the important fuel efficiency index since
Fuel Consumption over Duty cycle
Notch-wise percentage running of locomotive over duty cycle for passenger and freight operations of Indian Railways locomotives is as under:
Fuel consumption (in kg/hr) over duty cycle is calculated by taking weighted average of fuel consumption at every notch over duty cycle.
- All values are in gm/bhp-hr
- Measurements made with Portable equipment only
The head of the maintenance unit has to establish environmental policy keeping in mind the following aspects :
The procedures for disposal of waste materials includes:
All values in gm/bhp-hr
