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

Hybrid cars: Are Hybrid Cars Becoming Safer or More Harmful to the Environment? I. Introduction Hybrid cars have a very special technology because they boast two power sources: a regular gasoline engine and an electric motor powered by a huge battery unlike conventional cars which have only regular gasoline engine. These components generally work in tandem‚ though the exact mechanism varies depending on the car. When the car is at stop‚ the engine shuts off. While you push the accelerator

The definition of the efficient frontier says that “the efficient frontier represents the set of portfolios that has the maximum rate of return for every given level of risk‚ or the minimum risk for every level of return.” I plotted standard deviation on x axes and Returns on y axes to interpret efficient frontier. Exhibits also include these and the graphs you asked for as graph2: In our study‚ we concentrated on the optimal portfolios‚ the one which has the lowest volatility or risk‚ for given

Developing Fuels * All gases take up the same volume under the same conditions. AT room temperature and room pressure this volume is 24 dm3. * Number of moles= volume in dm3 24 * Balanced equations can also be used to work out gas volumes. In the equations: 2Na + 2H2O 2NaOH + H2‚ where 15g of sodium is reacted‚ you can work out the volume of gas from working out the number of moles in 15g Na = 0.65 mol. Then you see that 2 mol of Na 1mol of H2‚ Thus 0.65 mol Na 0.325 mol H2. 0.325

Hybrid vehicles have special options that allow for better fuel efficiency. One of those options is an idle stop. This option allows the gasoline engine to turn off when the vehicle stops yet still charge the battery packs. Meanwhile gas powered vehicles run the entire trip using only gasoline. The advantage

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).

Hybrid Cars Hybrid cars are the transportation of the future. Humans have been driving around since the 1880’s. They started off as simple‚ one-cylinder machines‚ to today‚ where they are twelve cylinder animals. From fuel-efficient coupes‚ to gas guzzling SUVs‚ or even the ultra expensive supercars‚ all use gasoline. The use of this gasoline makes or breaks the selling point of the car. We base the cars off of their utility; the gas-guzzlers may be the ones with the most torque and pulling

An efficient market is a market in which prices can always fully reflect available information. According to Andrei Shleifer‚ Market efficiency is theoretically based on three conditions‚ which are investor rationality‚ independent deviations from rationality and unlimited arbitrage. If three conditions cannot be satisfied‚ the market might be not efficient. Thus‚ investors’ rational behavior leads to stock market efficiency. For instance‚ when a company releases new information‚ for all investors

What are cars? What are motor cycles? Briefly‚ how do they contrast? How do they compare? What are their prices at the surface level? Thesis Statement: This essay seeks the comparison of cars and motorcycles. II. DEVELOPMENT Comparison a) Both cars and motorcycles are vehicles for transporting one or more persons. b) Both cars and motorcycles need fuel. Fuel serves a vital art in both cases as it supplies the energy required are the engines to work properly. c) Both cars and motorcycle
