Optimisation design of an energy management strategy for hybrid vehicles
This paper presents an innovative method to analyse and design an optimal energy management strategy for a power-split power train hybrid vehicle. A hybrid dynamical system theory is introduced to formulate the problem of hybrid vehicle control system design that incorporates both continuous and discrete dynamics. The sequential quadratic programming method is proposed to optimise power ...

Effects of varying air-fuel ratio on the performance of a theoretical Diesel cycle
This paper analyses the effects of varying air-fuel ratio on the performance of a theoretical Diesel cycle under a temperature restriction as maximum. Amount of heat addition at constant pressure is defined as a function of fuel's energy with utilising the combustion efficiency. The amount of released energy into the cylinder restricts the compression ratio. Relations between the combustion ...

Rising fuel prices: solutions for the Field Service Industry
As global fuel prices rise, the cost of petrol and diesel in the UK continues to skyrocket. While rising fuel prices affect all sectors, these increases have an immediate effect on the Field Service industry. Businesses in the industry travel to clients daily, and as fuel prices soar, the pressure to pay fuel bills grows for business owners. While the fuel crisis is unpredictable, and there's no ...

Navy Launches “Great Green Fleet” Featuring Biofuel Powered Ships
On January 20, 2016, U.S. Navy (Navy) Secretary Ray Mabus and U.S. Department of Agriculture (USDA) Secretary Tom Vilsack launched a Carrier Strike Group (CSG) of ships running up to 50 percent biofuels as part of the "Great Green Fleet" (GGF) initiative. For now, the majority of the ships will run on a mix of 90 percent petroleum and 10 percent biofuels, partially due to the low price of oil as ...

Carbon tax - key instrument for energy transition!
Summary: Global warming is the most challenging problem facing humanity today due to the excessive use of fossil fuels. Carbon tax (carbon dioxide tax) is a simple and efficient way to reduce the use of fossil fuels, improve energy efficiency, and make renewables more competitive. It can be tax neutral, as reducing other taxes will complement carbon tax implementation. It is a smart move to a ...

Methoxytriethyleneoxypropyltrimethoxysilane
Methoxytriethyleneoxypropyltrimethoxysilane can form covalent bonds with the polymer chains, creating a three-dimensional structure that is more resistant to degradation. Thus, it is frequently used as a crosslinking agent in polymers. Methoxytriethyleneoxypropyltrimethoxysilane provides the abilities of reducing friction between surfaces and resistance to adhesive. So, it can be used as a ...

Redefining Strength and Lightweight Design with Carbon Fiber Composites
Strength and lightweight design are essential considerations for engineers across numerous industries, ranging from aerospace and automotive to sporting goods and infrastructure. Carbon fiber composites are a class of materials that offer a remarkable balance of strength and lightweight properties, which have made them increasingly popular as an alternative to traditional materials such as metals ...

Rise in flights will outweigh carbon cuts
The aviation industry insists that it is making only a tiny contribution to global warming, with just 2% of global carbon dioxide emissions coming from its aircraft. The problem is the speed at which aviation itself is growing. One aircraft builder believes the number of planes in service in 2011 will have doubled by 2031. Whatever the industry’s efforts to reduce its carbon emissions, ...

Falling Gasoline Use Means United States Can Just Say No to New Pipelines and Food-to-Fuel
Freeing America from its dependence on oil from unstable parts of the world is an admirable goal, but many of the proposed solutions—including the push for more home-grown biofuels and for the construction of the new Keystone XL pipeline to transport Canadian tar sands oil to refineries on the U.S. Gulf Coast—are harmful and simply unnecessary. Gasoline use in the United States is ...

Three models of social change
Can we change fast enough? When thinking about the enormous need for social change as we attempt to move the world economy onto a sustainable path, I find it useful to look at various models of change. Three stand out. One is the catastrophic event model, which I call the Pearl Harbor model, where a dramatic event fundamentally changes how we think and behave. The second model is one where a ...

More Power & Efficiency on a 7FA in the Middle East at 50°C Case Study
Powerphase collaborated with the Tamimi Group of Companies and Saudi Electricity Company (SEC) to demonstrate Turbophase system’s ability to boost F-class gas turbine (GT) power output at the high ambient air temperatures that Saudi Arabian summers are known for. Besides having hot summers, Saudi Arabian labor costs are high such that any technology that reduces plant downtime can help ...

Coming In Out of the Cold: Hybrids Put to the Test
Untitled Document Point Roberts, WA, Delta B.C.- May 25, 2004 With gas prices reaching an all time high and not much promise of an end in sight, hybrid technology is falling under the lens of some careful scrutiny these days with investors. In a recent article in MITs Technology Review, author Peter Fairley estimates though buyers would have to pay more ...

New Fuel Efficiency Standards for Heavy-Duty Vehicles Are a “Win-Win-Win”
America’s vehicles are on the road to becoming cleaner. Last week, President Obama directed his administration to set new fuel efficiency and greenhouse gas (GHG) emissions standards for medium- and heavy-duty vehicles, including large pick-up trucks, school buses, and tractors. Improving fuel efficiency standards from these vehicles—which make up 20 percent of U.S. transport ...
