Comparison between Manual Gear and Automatic Gear Research Paper

Comparison between Manual Gear and Automatic Gear - Research Paper Example Such a transmission is made up of a series of gears that are used to produce the rotational force needed to turn the wheels of the vehicle. The transmission unit of a car which is commonly called a gear box has gears which transfer power form the engine of the car to its wheels. The transmission has to be equipped with multiple gears in that the car operates on the proper gear in different situations. The gearboxes are of multiple types with the difference being the determinant factor of how a car will operate. There are two main types of gears; manual gear and automatic gears. Modern cars have been equipped with two major transmission options, namely; manual or automatic transmission. There exist a number of differences between these transmission types with regards to their components, how they operate, the advantages and disadvantages associated with them and their applications. This paper is going to look at the differences evident between automatic transmission and manual transmission. A manual gearbox type is a car transmission which permits the driver to choose gears as he or she wishes with the use of a stick shift. For the driver to select the desired gear, the clutch pedal has to be depressed making it unique to cars with manual transmission (Zheng W. Chung et al 2007). This move disengages the gearbox disconnecting it from the engine. Once the desired gear has been chosen through having the shifter moved to the correct position, the clutch is now free and can be released. This action reconnects the gearbox and the engine. Manual transmission can be classified into two types; the constant-mesh type and the sliding-gear design. In the sliding gear design, its main parts are the cluster and drive gear. On each gear is a dog clutch fitted with a hub, a shaft and an outer ring (Zheng W. Chung et al 2007). Synchronizers are also fitted to prevent clashing of the gears. The hub mainly splines the drive gears while

Alternative Fuel Vehicle - Essay Example Global private sector and government vehicle fleets are the main users of alternative vehicles and fuels, but, in the modern world today, consumers are intensively interested in use of alternative fuels and fuel vehicles. Environmentalist and ecological scientist agree that, alternative fuels and sophisticated vehicles rather than conventional cars and fuels aid the world reduce petroleum consumption, and emissions for fuel combustions and vehicles. Using Monroe motivated sequence form of argument; the paper will investigate alternative fuel vehicles, their economic, technological and ecological benefit to both consumers and the government in a global arena. Discussion Alternative fuel cars or vehicles are vehicles that use alternative fuel such as electricity, alcohol and natural gas instead of other traditional petroleum products (diesel and gasoline). Any engine moving strategy does not utilize petroleum products, (Wheeler, 2008). The percentage of light-duty cars is predicted to increase by 2030; therefore, need to create ecologically friendly and low fuel consumption vehicles are increasing. Enhancing the efficiency of vehicles is the only effective way to lower dependence on petroleum and improve environmental and public health security. Environmentalist and energy commission have construed that enhancing vehicle efficiency is not enough. Therefore, the world and the car industry must focus on enhancing their use of alternative fuel vehicles and fuels such as electricity, alcohol and other renewable sources. Alternative fuel cars offer increasingly impressive advancements in the fuel commercial. Similarly, alternative fuel cars that combine internal ignition engine of a car convention with an electrical motor can attain approximately two times the conventional cars fuel economy, (Carson & Vaitheeswaran, 2007). The system of energy storage maintains the energy to move the electric motor, for instance, batteries are most popular choices of energy storage in alternative fuel cars. Additionally, researchers are still under investigation to develop other options for storing energy. Experts agree that various increased fuel taxes in different parts of the world (such as Europe), strict environmental laws (such as California environmental laws) and increased chances of further restrictions on emission of greenhouse gases, operations on alternative systems of power for heavy fleet vehicles have become a main concern for manufacturers of vehicles and governments across the globe. Other compelling factors behind AFV manufacture include increased need to promote healthcare safety and other economic benefits, (American Petroleum Institute & World Resources Institute, 1990). Modern research and development mainly focus on AFV machines run by internal ignition and electric energy, (California & California, 2009). Alternative fuel cars minimize smog-forming contaminants through efficient locomotion, but because their internal ignition engine they produce minimal emissions. Similarly, increasing gas costs, environmental pollution and advanced techniques are the main contributing factors to the rising popularity for safe fuels for hybrid vehicles. This is because alternative fuel cars by far, supersede fossil fuel by running on hydrogen, electric power, ethanol and related renewable alternatives. Alternative fue
