Diesel engines and unleaded fuel engines better known as gasoline engines are actually very similar. They are both internal combustion engines which is to convert the chemical energy in fuel into mechanical energy. This mechanical energy moves pistons up and down inside cylinders. The pistons are connected to a crankshaft‚ and the up-and-down motion of the pistons‚ known as linear motion‚ creates a force to the flywheel the from the flywheel to the transmission. The working principle of diesel engines

Ethanol‚ a Fuel? Ethanol fuel is a type of alcohol found in alcoholic beverages that is often made from common agricultural products. It is either mass-produced by fermentation of sugars or from cellulose. Wheat or corn kernels are ground in a hammer-mill to expose the starch‚ the ground grain is then mixed with water‚ heated briefly and enzymes are added to convert the starch to sugar using a chemical reaction called hydrolysis. Yeast is added to ferment the sugars to ethanol and finally the

Ethanol fuel is ethanol (ethyl alcohol). Ethanol‚ also called ethyl alcohol‚ pure alcohol‚ grain alcohol‚ or drinking alcohol‚ is a volatile‚ flammable‚ colorless liquid. A psychoactive drug and one of the oldestrecreational drugs known‚ ethyl alcohol produces a state known as alcohol intoxication when consumed. Best known as the type of alcohol found in alcoholic beverages‚ it is also used in thermometers‚ as a solvent‚ and as a fuel. In common usage‚ it is often referred to simply as alcohol or spirits

Disadvantages of alternate fuels The truth about the manufacturing and use of alternate fuels‚ as with everything else in life‚ is a mix of benefits and cost. Electricity is one of the alternate fuels that made it to production. The Chevy Volt is one such vehicle. The problem with this car is that it cost $41‚000 to buy one‚ and the battery life for a charge is only 37 miles. There would be no value for us to use electric cars. (Courture‚2011). Ethanol

various renewable energy sources‚ fuel cell technology has received great attention as an alternative to the conventional way of getting energy due to its high efficiency‚ clean operation and cost efficient supply of power demanded by the consumers. Proton exchange membrane (PEM) fuel cells technology plays a leading role for many applications when comparing with other competitive types of fuel cells. The world is in high demand for clean alternative fuel source and PEM fuel cells could be that change with

clues to the Earth’s and Mankind’s past; expeditions spanning the globe are often launched in search of fossils. Soft-shelled fossils are extremely rare due to their inherent fragility and rarity of necessary conditions to preserve such specimens. The Burgess Shale formation located in British Columbia contains some of the best-preserved and most abundant collections of soft-shelled fossils known. Referred to as a Lagerstatten; or “place of excellent preservation”‚ the Burgess houses many relatives

alternative fuel for airplane‚ which is a serious argument; however‚ big question is that efforts to produce a more sustainable fuel to power aircraft are technically and ethically feasible. This paper going to investigate and show there is no alternative fuel to power aircraft in this time. The fuel using by airplane is fossil fuel‚ which is Jet A1 by burning this fuel there are impact on the global warming the researcher investigate what is the problem with fossil fuel (Jet A1).

float-type carburetor‚ the purpose of the economizer valve is to Provide a richer mixture and cooling at maximum power output 3. The fuel metering force of a conventional float-type carburetor in its normal operating range is the difference between the pressure acting on the discharge nozzle located within the venture and the pressure Acting on the fuel in the float chamber 4. If the main air bleed of a float-type carburetor becomes clogged‚ the engine will run Rich at rated power

FUEL OIL BURNERS By Mark Butterfield March 09 INTRODUCTION The history of burners dates back to the early shipping days‚ when fuel oil first started replacing coal as the ships’ primary fuel source. Since then‚ burner designs and construction have come a long way‚ but the principles behind their operation has remained the same. All makes and types of burners have two things in common They need to atomise the fuel They need to mix the fuel with the air needed for combustion

FUEL CELL CARS Fuel Cell cars are a major part of the fleet of Zero-Emission Vehicles. The fuel cells are fueled with pure hydrogen and hence they are considered to be zero emission vehicles. Fuel cells have been used on spacecraft for many years to power electric equipment. These are fueled with liquid hydrogen from the spacecraft ’s rocket fuel tanks. Basic Mechanics Fuel cell vehicles turn hydrogen fuel and oxygen into electricity. The electricity then powers an electric motor‚ just like
