After a challenging transition to BS6 in April 2020, the Indian auto industry is now studying the next batch of emissions standards that will take effect in 2022-23. Despite time constraints, automakers believe they will be able to reach their goals on time. โTechnically, we can do this,โ said Krishnan Sundararajan, MD, of the Renault Nissan Business and Technology Center in India, organized in our sister publication โAutomobile Expertโ Meeting Emissions Challenge, โsaid at the virtual meeting.
He added:โ To BS6 Phase 2, our response is not as bad as it was for BS6. โGasoline engines require scheduled fuel injection hybrids and electric vehicles are essential to meet CAFE regulations. With new emissions regulations in 2022, passenger car prices will go up. The new corporate average fuel economy rule (CAFE 2) will launch a new round of regulations in April 2022, which will allow any automakerโs fleet The average CO2 level of China has reduced from the current 130 g / km to 113 g / km.
The following year, the Real Driving Emissions (RDE) specification will require cars to meet emissions targets even under realistic conditions, not just in the lab environment. Then the second stage of BS6 (or BS6.2) was established to make the emission limits of car manufacturers more difficult to adjust than before.
BS6 Phase 2:
Explaining the strategy to achieve stricter goals, Sundararajan said: โWhen upgrading from BS6.1 to BS6.2, we know very well that the technology used in Europe cannot be copied and pasted here. Therefore, We have to adapt. We have passed with enough time to make this adjustment, we are working hard to solve the problem of 2023.
Semiconductor-related software (updated). โFor reference, the scheduled fuel injection is based on the monitoring of various parameters (such as throttle position and, engine sensors inputs such as intake air temperature, temperature and pressure and oxygen content in the exhaust) are used to control the timing and amount of fuel injection in a gasoline engine. โNow all of our power and energy is optimizing PGM and figuring out how we will run it on a large scale based on all the technologies we want to use in BS6.2.
Sundararajan said: โWe are looking at how to optimize the PGM Innovation gaps to manage costs, such as extending the technology to more types of cars. As Europe has established stricter regulations, luxury car manufacturers have set conditions for BS6. โWith the introduction of new engines that we made around the 2019-20 season, all of our cars around the world meet Euro 6d standards. This helps us prepare for todayโs Phase 2 (BS6) specifications.
CO2 targets will have a significant impact on internal combustion (IC) engines. โMeeting the (new) CAFE requirements will obviously require us to have an alternative powertrain, be it an electric vehicle (EV) or a hybrid vehicle or other products. However, it is clear that the IC engine alone is not enough. to meet CAFE requirements in 2022. โFormer CEO and CEO of Mahindra and Mahindra said, Dr. Pawan Goenka.

Electrification will be more prominent:
When talking about the technology needed to achieve the goals of CAFE 2, Mahindra and Mahindraโs director of global product development, R Velusamy, said: โIn cars (and hatchbacks), it is mainly used gasoline, so it must be combined with motorized vehicles. They are used together. โHowever, he mentioned that between 1% and 5% of battery electric vehicles (BEVs) sold in this segment can also help achieve the same results.
Velusamy said: โTo a large extent, T-GDI (Turbo Gasoline Direct Injection) and diesel engines compensate automakers who do not want to build hybrid vehicles.โ Diesel has lower carbon dioxide emissions than gasoline. engineering supervisor, this means that the SUV only needs to rely on โcertain internal engine measuresโ to achieve CAFEโs overall goal. Other strategies, such as reducing vehicle weight. Butt and reduced drag and rolling resistance can also have a significant impact. However, he added, depending on the automakerโs exact SUV portfolio, there may still be a need for โa certain percentage of battery electric vehicles.โ
Adding technology requires a certain price:
Obviously, any form of electrification will drive up car prices. However, even other measures (such as scheduled fuel injection) come at a price. โYou will pay a higher price for PGM. Similarly, in semiconductors, like it or not, all wafers will enter the non-automotive field due to COVID. Fixes, PGM still needs to be fixed, and there will be some difficulties in achieving milestones in the right time and at the right cost, โsaid Renault-Nissanโs Sundararajan.
He added:โ Technically speaking, we can do this, but we have to pay attention to the affordability or TCO (total cost of ownership) of the customer. โ
