Alcohol To Make Your Car Climate Friendly!
The unit, called a direct-injection ethanol engine, runs primarily on petrol. When it needs to deliver maximum power, like climb a hill or overtake, the engine management computer adds a little ethanol to the fuel injected into the combustion chambers. This arrangement allows the engine to operate at a much higher compression ratio - a measure of the amount by which the fuel-air mixture is compressed before being ignited - than normal.
The above usage downsizes an average car engine to one that should have around 23 per cent better fuel efficiency. Normally, the downside of a high compression ratio is that it encourages premature ignition or “knocking", which drastically cuts down the power output. Adding ethanol to the fuel suppresses knocking.
The next step is to road test the engine in a variety of vehicles and to ensure that the engine does not become unusable if the ethanol tank runs dry. Ford said that its ethanol-assisted engine would cost 1100 to 1500 dollars more than a conventional engine. This is just one-third of the extra cost of a hybrid petrol-electric engine over a normal petrol engine. Hybrids typically deliver 25 to 35 per cent better fuel economy than a conventional engine.
