Tartu Kutsehariduskeskus Autode ja masinate remondi osakond Rainer Kaine AT-109 Iseseisev töö Electric cars Instructor: Tauris Vijar Tartu 2010 Introduction In this essay i´m write electric cars and this how these cars are built, how easy is built electric car, how much costs electric cars. The problems for electric cars, there are many problems why peoples still can´t use quiet and more green cars. But even the electric car is not all green because the electricity produced for nuclear, coal, oil shale and natural gas. These ways to get electricity pollutes nature, the only difference between lies in the fact that pollution is in the one place.

1)Main machinery On a ship, the engine room, or ER, is the propulsion machinery spaces of the vessel. To increase the safety and damage survivability of a vessel, the machinery necessary for operations may be segregated into various spaces. The engine room is one of these spaces, and is generally the largest physical compartment of the machinery space. The engine room houses the vessel's prime mover, usually some variations of a heat engine - diesel engine, gas or steam turbine. On some ships, the machinery space may comprise more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be simply numbered. 1.1)Main engine The engine room of a motor vessel typically contains several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. They typically burn diesel oil or heavy fuel oil, and may be able to switch between the two. There are many propulsion arrangements for motor
the shaft. This serves two purposes: It cools the shaft and some of the other turbocharger parts, and it allows the shaft to spin without much friction. One of the main problems with turbochargers is that they do not provide an immediate power boost when you step on the gas. It takes a second for the turbine to get up to speed before boost is produced. This results in a feeling of lag when you step on the gas, and then the car lunges ahead when the turbo gets moving. SUPERCHARGER Adding a supercharger is a great way to achieve forced air induction.A supercharger is any device that pressurizes the air intake to above atmospheric pressure. Superchargers are powered mechanically by belt- or chain-drive from the engine's crankshaft. Getting more fuel into the charge would make for a more powerful explosion. But you can't simply pump more fuel into the engine because an exact amount of oxygen is required
Indroduction This assignment will examine Britain's car market and shows how the external and internal environment factors influences it, mostly on Mini Ltd. External marketing environment is divided into 4 different groups; socio-cultural, economic, technological and political factors. Internal marketing evironment is divided into 6 different groups; which are customers, competitors, suppliers, distributors, employees and stakeholders. Also this assignment is
sense the onset of a rollover event. If a rollover event is determined to be imminent, side-curtain airbags are deployed to help protect the occupant from contact with the side of the vehicle interior, and also to help prevent occupant ejection as the vehicle rolls over. Hydropneumatic is a type of automotive suspension system, invented by Citroën, and fitted to Citroën cars, as well as being adapted by other car manufacturers, notably Rolls-Royce, Mercedes- Benz and Peugeot. It was also used on Berliet trucks. Similar systems are also used on some military vehicles. The purpose of this system is to provide a soft, comfortable, yet well-controlled ride quality. Its nitrogen springing medium is approximately six times more flexible than conventional steel, so self-leveling is incorporated to allow the vehicle to cope with the extraordinary suppleness provided

Two-Stroke TUNER’S HANDBOOK By Gordon Jennings Illustrations by the author Copyright © 1973 by Gordon Jennings Compiled for reprint © 2007 by Ken i PREFACE Many years have passed since Gordon Jennings first published this manual. Its 2007 and although there have been huge technological changes the basics are still the basics. There is a huge interest in vintage snowmobiles and their “simple” two stroke power plants of yesteryear. There is a wealth of knowledge contained in this manual. Let’s journey back to 1973 and read the book that was the two stroke bible of that era. Decades have passed since I hung around with John and Jim. John and I worked for the same corporation and I found a 500 triple Kawasaki for him at a reasonable price. He converted it into a drag bike, modified the engine completely and added mikuni carbs and tuned pipes. John borrowed Jim’s cop
cooling, cleaning, preparing food, transportation, and communication devices. They discovered that the amount of energy used for any purpose could be measured in different ways. Light bulbs are measured in watts. Air conditioners and hot water heaters are measured in BTUs, while energy used by cars is measured in gallons of fuel. They used a spreadsheet to figure out how much energy they consumed for each of their activities. Each of the lights, car miles, games, and other appliances was converted to a common unit of power consumption called kilowatt-hours. The spreadsheet was used to determine how many kilowatt-hours were used during each day, each week, and each year for each energy consumption activity. The spreadsheet converted their energy consumption to show them the amount of money it costs for each energy consumption activity. In the end, they were shocked to see how much money Jules' energy using habits cost compared to Les' habits
