Hey guys,

So I am a policy enthusiast (other than being an automotive enthusiast) and I am writing a policy memo, which I could maybe get published and I am looking into this topic. Is it at all possible for you guys to maybe direct me to links to research or academic work done on this topic? It would greatly help me because I would like to make my report data-rich and not just qualitative in nature. Any help would be immensely appreciated as I too believe this is a bad policy with ulterior motives in mind.

Start from here: https://www.team-bhp.com/forum/india...ml#post5860145 (Government of India mulls ethanol blending in diesel | EDIT: 15% blending being pursued)

Other members have also shared their views and many links of data related to this topic in the follow up which maybe beneficial for you.

Just wanted to understand - how do car manufacturers make the engines compliant to E20 fuel. Does it involve some components in the engine to be changed to make sure they are able to resist the impact of change in fuel mixture. Apologies if it’s already discussed and if it’s not the right thread.

Ethanol is corrosive, which can lead to accelerated wear and tear of engine components, particularly those made of plastic and rubber, such as fuel lines and gaskets. Additionally, ethanol has a lower energy density than petrol, potentially resulting in a leaner air-fuel mixture, which can cause engine misfires and reduced performance.

To make engines E20 fuel compliant, car manufacturers primarily focus on engine and fuel system modifications, including using ethanol-resistant materials and implementing closed-loop fuel injection systems. They may also need to tune the engine for greater ethanol blends, potentially increasing compression ratios and thermal efficiency.

1. Engine Modifications:

Materials: Manufacturers use materials in the engine that are more resistant to ethanol's corrosive effects on rubber and soft metal parts, such as rubber hoses, seals, and fuel lines.

Engine Tuning: Engines are tuned to optimize performance with ethanol blends, which may involve adjusting compression ratios and improving thermal efficiency.

Closed-Loop Fuel Injection: Some manufacturers are implementing closed-loop fuel injection systems that use a lambda sensor to constantly adjust the air-fuel mixture for optimal performance with E20 fuel.

2. Fuel System Modifications:

Fuel Lines and Connectors: Fuel lines and connectors are often made of materials that can withstand the corrosive effects of ethanol.

Fuel Tank and Fuel Pump: The fuel tank and pump may also need to be modified to ensure they are compatible with E20 fuel.

I recently purchased a facelift Ford ecosport Ecoboost S variant (2018 November). Any idea if it's E20 compliant?

Any idea whether Honda Activa scooter 2010 model can survive the available petrol (normal/XP95) ?
My owner's manual just gives general guideline: "usage of alcohol containing fuel beyond the approved limit will be considered abuse"
