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

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

Abstract This report explains how advantageous a hybrid car is and why conventional car should be replaced by hybrid car. Hybrid car is getting more popular and marketable because of its advantages. In essence‚ the report touches on the benefits of owning a hybrid car and some possible effects. The problems that arisen are environmental problems which catch the whole world’s attention‚ the prices and fuel are hiking up and the fuels are limited in supply. Therefore‚ hybrid cars are here to help

Air pollution and its health impacts on three cities Air pollution has a significant impact on human health. It can cause death by compromising the respiratory and cardiorascular system‚ or by its toxic carcinogenic effects. Transport is the greatest source of air pollutions‚ owing to increased numbers of cars in the city. Moreover‚ manufacturing and factories are another reason for air pollution. Results from the government not having suitable policy on air pollution are becoming more and more

downward‚ a partial vacuum is created inside the barrel. This partial vacuum then draws air past through the carburetor’s throat and into a nozzle that sprays fuel. The mixture of air and fuel in the carburetor is then delivered into cylinders for combustion. The amount of air pulled through partial vacuum created by the pistons is controlled by a throttle valve. The throttle valve is found at the base of the carburetor. When a driver

or ECU (also known as an "engine management system") is an electronic device‚ basically a computer‚ in an internal combustion engine that reads several sensors in the engine and uses the information to control the fuel injection and ignition systems of the engine. This approach allows an engine’s operation to be controlled in great detail‚ allowing greater fuel efficiency‚ better power and responsiveness‚ and much lower pollution levels than earlier generations of engines. Because the ECU is dealing
