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

Byoliveridley

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…

Carbon Trends 2007

Byoliveridley

Emissions increased from 6.2 PgC per year in 1990 to 8.5 PgC in 2007, a 38% increase from the Kyoto reference year 1990. The growth rate of emissions was 3.5% per year for the period of 2000-2007, an almost four fold increase from 0.9% per year in 1990-1999. The actual emissions growth rate for 2000-2007 exceeded the highest forecast growth rates for the decade 2000-2010 in the emissions scenarios of the Intergovermental Panel on Climate Change, Special Report on Emissions Scenarios IPCC-SRES. This makes current trends in emissions higher than the worst case IPCC-SRES scenario. Fossil fuel and cement emissions released approximately 348 PgC to the atmosphere from 1850 to 2007.

Carbon Trends 2007.

This is very scary news, and there’s more in the carbon budget for the last 7 years released here. It shows a total lack of leadership from the US, Canada, and Europe, countries responsible for over 80% of the historical anthropogenic contribution.
