meaning‚ direct injection of the fuel into the cylinders of a diesel engine via a single‚ common line‚ called the common rail which is connected to all the fuel injectors. Whereas ordinary diesel direct fuel-injection systems have to build up pressure anew for each and every injection cycle‚ the new common rail (line) engines maintain constant pressure regardless of the injection sequence. This pressure then remains permanently available throughout the fuel line. The engine’s electronic

Energy Fossil Fuels Good Bad and Ugly Abstract Energy is an important part of our everyday lives. Energy can come in many different types‚ and forms it can be used for many different purposes. Energy has many different usages and can be converted from one form of usage to another form of usage depending on what the need is. One form of energy conversion is the use of food to supply people ’s bodies with energy. Another form of energy

which is made from fossil fuels. Fossil fuels such as oil‚ coal‚ and natural gas are nonrenewable resources. They will run out one day and that’s what the U.S. relies on for gas and electricity. Renewable energy such as solar‚ wind‚ and hydropower are infinite sources. The U.S. depends on the finite resources of fossil fuels greatly‚ yet they have the ability to use renewable energy. The oil boom dates back to Henry Ford and John D. Rockefeller and some say that fossil fuels have reached the end of

The industrial revolution has brought with it technological advancement‚ such as the discovery of oil and fossil fuels and its virtually universal use in a diversity of industries. Further more rapid growth in population is established to be the fundamental cause of environmental framework collapse. Population growth increases the need to produce consumer commodities

Alternate fuels should be economically attractive in order to compete with currently used fossil fuels. In this work‚ biodiesel (ethyl ester) was prepared from waste cooking oil collected from a local restaurant in Halifax‚ Nova Scotia‚ Canada. Ethyl alcohol with sodium hydroxide as a catalyst

are looking for alternative sources of energy. These include wind‚ solar and hydro energy sources‚ known as renewable sources (Able to be regrown). However‚ one fuel source in particular is currently being used and produced to power both vehicles and electrical generators around the world; biofuels. Biofuels are renewable gas or liquid fuels made from plant matter such as corn‚ sugar cane and vegetable oils. The two main types of biofuels are known as ethanol and biodiesel; both made from feedstock
