New Device could make internal combustion 15-20% more efficient

Improving engine efficiency and reducing pollutant emissions are extremely important. Here, we report our fuel injection technology based on the new physics principle that proper application of electrorheology can reduce the viscosity of petroleum fuels. A small device is thus introduced just before the fuel injection for the engine, producing a strong electric field to reduce the fuel viscosity, resulting in much smaller fuel droplets in atomization. Because combustion starts at the droplet surface, smaller droplets lead to cleaner and more efficient combustion. Both laboratory tests and road tests confirm our theory and indicate that such a device improves fuel mileage significantly. The technology is expected to have broad applications, applicable to current internal combustion engines and future engines as well.

Electrorheology Leads to Efficient Combustion.

According to the press release, this is a very simple device. It has one small advantage over the usual snake oil, it is academic research and has been peer reviewed.

Good stuff, hope this is an easy after market addition to any vehicle with fuel injection. However, the press release also notes that the prototype is being developed for diesel engines only, and that the research was based mainly on diesel, wonder why…

    The main flaw in the whole scheme is the (wrong) assumption that in diesels (and also in gasoline engines) up to 20% of the fuel escapes to exhaust without burning. This is patently wrong. And it is the starting point in all scams related to the similar “fuel saving” devices. In modern diesel and gasoline engines, built within the last decade or so, 98-99% of the fuel is burned; only 1-2% of the fuel may survive combustion and end up in the exhaust. Applying a strong electric field to the fuel line may produce finer droplets, but it will not produce 20% more energy because the margin is already 1-2%, if any. A more technical criticism pointing the main flaws in Dr. Tao’s study has just been published by the same journal Energy and Fuels: “Gulder “Comments on Electrorheology Leads Efficient Combustion by Tao et al.” Energy and Fuel s, ASAP in press (doi:10.1021/ef800829v).
