Fuel Efficiency

Printer-friendly version

India's dependence on imported fossil fuels rising continuously due to the limited domestic petroleum resources. India ranked as the fourth-largest petroleum consumer in the world following China, the United States, and Russia. The country's energy demand continues to climb as a result of its dynamic economic growth and modernization. India’s consumption of petroleum products increased by 5.3% to previous year which is more than 200 MMT causing a significant expenditure on oil import. Keeping in view the growing demand of fossil fuel and rapidly growing motor vehicle fleet in India, Govt. of India set a target to reduce 10% reduction on import by 2022. BEE is working on the Development of fuel efficiency norms for Vehicles that could moderate the rising demand of fuel.

Fuel Economy Norms for Heavy Duty Vehicles:

In August 2017 the Government of India finalized fuel efficiency norms for commercial vehicles (CVs) with a gross vehicle weight (GVW) of 12 tonnes or greater. Manufacturers must demonstrate compliance with the rule by evaluating vehicles over the constant speed fuel consumption (CSFC) test procedure. In the CSFC protocol, trucks are driven at constant speed on a test track at 40 and 60 kilometres per hour (kph), and buses are run at 50 kph. Recently Ministry of Road Transport and Highwayshas revised the safe axle weight limits, subsequently the norms for HDVs is under review to meet the revised GVW range.

Corporate Average Fuel Economy Norms for Passenger Cars:

The Government of India, Ministry of Power, issued average fuel consumption standards for cars on 23rdApril 2015.This standard is applicable for the motor vehicle using petrol or diesel or liquefied petroleum gas or compressed natural gas, which carry passengers and their luggage and comprising not more than nine seats including driver’s seat, and of Gross Vehicle Weight not exceeding 3,500 kilograms tested.

            The fuel consumption standards would be effective from 2017-18 onwards, and a second set of standards would come into force from 2022-23. The standards relate the Corporate Average Fuel Consumption (in liters/100 km) to the Corporate Average Curb Weight of all the cars sold by a manufacturer in a fiscal year.

            According to the first standard, the average weight of all cars is expected to be 1037 kg in 2016-17, and the Average Fuel Consumption Standard would have to be less than 5.49 km/100 liters for this average weight. The second standard assumes car average weight of 1145 kg in 2022, and requires the average fuel consumption to be less than 4.77 l/100km at this average weight.

            It may be noted that the standards apply to the Corporate Average Fuel Consumption i.e. the average of the standard fuel consumption of all vehicles sold by the manufacturers in the fiscal year, and not to the fuel consumption of an individual model.  The fuel consumption is measured under standard conditions at the nationally accredited labs over the national driving cycle.

It is expected that these standards would lead to a reduction of 22.97 million tons of fuel consumption by 2025.

Fuel Economy Norms for Light & Commercial Vehicles: In addition to norms for CVs greater than 12 tonnes, the development of fuel efficiency standards for CVs between 3.5 and 12 tonnes has been completed. The norms for this lighter segment of CVs is centred around CSFC testing.  The norms has been finalised and notified by Ministry of Power on 16th July 2019 in the Gazette of India.

Fuel Efficiency Standards/Star Labelling forAgricultural Tractors:

The tractors are different than other types of vehicles & preferably used as a machine for various processes like cultivation, traction etc. Development of Fuel Economy norms for Agricultural tractors is also under process and likely to be finalised soon. It will be preferably “Star Labelling programme for Tractors”.


Other initiatives in Fuel Efficiency in Transport Sector:

There is huge scope of fuel saving by on-road vehicles also. Tyres as an important component of vehicle has been identified for potential saving of the fuels. Approximately, 2/3rd market of tyres is replacement by customers. Keeping this in mind, Standard and Labelling programme for vehicular tyres has been initiated also.

            The vehicle fuel efficiency is being tested prior to the launch of a model. Presently the test procedure which are in place, are costly and consumes much time & energy. So, it is required to develop a tool which can assess the fuel efficiency of a vehicle without performing any physical test. BEE hasinitiated the development of a computer-based simulation tool (like VECTO in EU) as per Indian specific conditions. The tool will be helpful to reduce the cost and time for testing of vehicles.
