Biomass is organic material made from plants and animals. Biomass contains fuel storage tank stored energy from the sun. Plants absorb the sun's energy in a process called photosynthesis. The chemical energy in plants gets passed on to animals and people that engine cooling system eat them. Biomass is a renewable energy source because we can always grow more trees and crops and fuel tanks, and waste will always exist. Some examples of biomass fuels are wood, crops, manure, and some garbage.
When burned, the chemical automobile parts energy in biomass is released as heat. If you have a fireplace, the wood you burn in it is a biomass fuel. Wood waste or garbage can be burned to produce steam for car shipping making electricity, or to provide heat to auto transport industries and homes.
Burning biomass is not the automoblie parts only way to release its energy. Biomass can be converted to other usable forms of energy like methane gas or auto transportation fuels like ethanol and biodiesel. Methane gas is the main ingredient of natural gas. Smelly stuff, like rotting garbage, and agricultural and human waste, release methane gas - also called "landfill gas" or "biogas." Crops like corn and sugar cane can be fermented to produce the auto transportation fuel, ethanol. Biodiesel, another transportation fuel, can be produced from left-over food products like vegetable oils and animal fats.
Biomass fuels provide about 3 percent of the energy used in the United States. People in the USA are trying to develop ways to burn more biomass and less fossil fuels. Using biomass for energy can cut back on waste and automobile parts support agricultural products grown in the United States. Biomass fuels also have a number of automover environmental benefits.

Posted by Kimberly Thursday, July 10, 2008diesel engine: mode of operation
1. Suction stroke: Pure air gets sucked in by the automobile piston sliding automobile downward.
2. Compression stroke: The piston compresses the automobile parts air above and uses automobile therby work, performed by the automover crankshaft.
3. Power stroke: In the automobile upper dead-center, the air is max. compressed: Pressure and Temperature are very high. Now the black injection pump injects heavy fuel in the hot air. By the high temperature the automobile fuel gets ignited immediately (autoignition). The automobile parts piston gets pressed downward and performes work to the crankshaft.
4. Expulsion stroke: The burned exhaust gases are ejected out of the auto cylinder through a second valve by the automobile piston sliding upward again.
First diesel engine prototypes
Posted by Kimberly Tuesday, July 8, 2008This principle is not as simple as it sounds. The conversion into the automover practice was very problematic. Such high pressures and temperatures had never been used automobile parts before, and the first experimental engine, built 1893 together with the Maschinenfabrik Augsburg (MAN) automover in Germany led to its destruction. Only a second automobile engine, built 1896, could convince the automobile engineers and performed an efficiency of about 25 percent, which was by far more than any other automobile engines performance at that time.
But the engine was not after automobile Diesel's requires yet: The compression ratio was still low and the max. pressure therefore small (about 30 bar), additionally a fuel injection was not yet possible. He had to use an air-injection, a procedure, which required many very complicated, expensive and heavy additional devices. This fuel engine could become generally accepted only with many difficulties, because of economic problems - fuel oil and petroleum were very expensive - and disputes about patents delayed a successful introduction.
Diesel's problems
Rudolf Diesel was pursued by patent quarrels, and scruplesless businessmen succeeded in acquiring rights for diesel's engine, so that he finally couldn't develop on his own automobile engine any more. Only 1908, when the patents had run and automover, he developed still smaller engines for the use in cars and trucks, together with the Swiss pioneer company Saurer. When he impoverished completely and didn't beleave any more in a successful advancement of his engine, he set an end to his life 1913 (see also biografie Rudolf Diesel).
