transportation is ran on oil based fuels. How much longer can we consume the resource until we run out of it? If someday we run out of oil‚ I think that the world should be prepared! Gasoline is a petroleum-delivered liquid that is used in internal combustion engines which are used in almost every type of transportation. Over the years‚ the consumption of gasoline is increasing‚ while the sources are exhausting. Many geologists propose that most of the sources of oil on Earth have reached so-called “peak

Hybrid cars are designed on running on both an electric motor and an internal combustion system‚ and Electric cars run entirely on electricity without having an internal combustion system. In fact‚ both of these cars contain a rechargeable battery that can be charged externally‚ which helps in reducing the usage of gasoline which can diminish air pollution and save the environment. For example‚ a recent study by Experian Automotive reports that 40% more hybrid cars were sold in the U.S. in 2012 than

emissions by more than 10%. The drive system featured in the BMW Concept 5 Series ActiveHybrid consists of a straight-six gasoline engine with TwinPower Turbo technology‚ eight-speed automatic transmission‚ and an electrical drive system developed specifically for this model fitted between the engine and transmission. An automatic clutch connects the gasoline engine and the electric motors. Drawing its energy from a high-voltage battery at the back of the car‚ the electric motor develops maximum

Case Memo: Plugging In" the Consumer: The Adoption of Electrically Powered Vehicles in the U.S. Date: 08-31-2013 The non-internal combustion engine (ICE) vehicles consists of hybrid electric vehicles (HEV)‚ plug-in hybrid electric vehicles (PHEV)‚ single-fuel all electric vehicles (EV)‚ and fuel cell vehicles (FCV). Earlier attempts at non-ICE vehicles were faced with many challenges resulting in abandonment of research and development. General Motors (GM) discontinued the EV1 electric vehicle

I remember at the time when I started to go to school‚ my father used to tell me how bad the conditions were when he was studying. How he studied sitting below street lamps when there was no electricity in the house‚ how he was forced to do a job leaving his graduation incomplete when they had not enough money even to buy books. Still he continued working hard and completed his graduation successfully. When I see myself having everything I need or even more than that‚ I don’t think I have a reason

ensure that the cylinder can stay in a given location in the brickwork or maintenance. The prime mover of the auxiliary drive‚ the majority of which is the motor‚ is power-supplied by the power different from the main motor and can also use Internal combustion engine to dispense with a power supply. There is an auxiliary reducer between the auxiliary motor and main gear box‚ the role of which is to achieve the request of the increase of speed ratio. Auxiliary motor should be equipped with brakes to

Determination of the heat of Combustion of Biodiesel Using Bomb Calorimetry Abstract: In this experiment‚ biodiesel fuel was synthesized from vegetable oil. Biodiesel is considered “green” and better for the environment because it is biodegradable. The heat of combustion was then determined using a bomb calorimeter. Introduction: Petroleum is the largest single source of energy consumed by the world’s population‚ exceeding coal‚ natural gas‚ nuclear‚ hydro‚ and renewables (3). It is predicted that

Mechanisation and Human Life Exercise 1 Mechanisation is providing human operators with machinery that assists them with the muscular requirements of work or displaces muscular work. In some fields‚ mechanization includes the use of hand tools. In modern usage‚ such as in engineering or economics‚ mechanization implies machinery more complex than had tools and would not include simple devices such as an un-geared horse or donkey mill. Automation/Mechanisation has had a notable impact in a wide

Honda and Hybrid Electric Vehicles Honda was founded in Hamamatsu‚ Japan‚ by Soichiro Honda in 1946 as the Honda Technical Research Institute. The company began as a developer of engines for bicycles‚ but by 1949 it had produced its first motorcycle‚ called the Dream. In 1959‚ Honda entered the U.S. automobile and motorcycle market by opening the American Honda Motor Company. A few years later‚ in 1963‚ Honda released its first sports car‚ the S500‚ in Japan. Honda Motor Co. Inc. grew rapidly
