The Effect Of Heat Engines On Energy Essay

The dependency on transportation in today’s society is quite remarkable. There are many forms that people take advantage of everyday including: planes, trains, and automobiles. Unfortunately, these diverse varieties of transportation do not run on imagination. For automotive vehicles, the most prevalent material used to operate are fossil fuels. There is a popular concern with the abundant reliance on these fossil fuels, which are a nonrenewable resource. The controversial usage has opened the discussion to alternative opportunities for fuel sources that, potentially, can replace the current fossil fuel being used in automotive vehicles. When considering the current market of cars, many have complaints in gas powered automobiles. There are many problems, commonly discussed, with emissions. Cars have a tendency to be harmful to the environment, and expensive to use frequently. This is where the alternatively powered cars are introduced into the conversation. There are multiple vehicles that can replace the prevalently operated, gas powered cars. However, alternatively powered vehicles must be considered in the same aspects a consumer would think about when buying a normal car. The buyer of automobiles, in the current market, look at the necessities that come with the maintenance and upkeep the car requires. Price, maintenance costs, insurance, incentives, and quality of life are

Environmental concerns have been raised from time to time because of the dependency on the gasoline-fueled engine as the chief auto powertrain technology. This has resulted in exposing many automobile users to unpredictable prices of fuel. These issues were, however, the reason for

In today’s motorized life , It’s difficult to live without motor (Engines) and the main source of it’s input power is fossil fuels & partly electric power. In future these fuels or electricity may not be available widely as they are non renewable energies. So, it may be difficult to use engine with the fuels.

The demand for an efficient renewable energy source is a driving force in ongoing research. Thermal energy conversion is one such potential source that is under constant investigation and has endless avenues of possibility. The two requirements of energy production are efficiency and renewability. Many possibilities exist for energy production including: Fossil Fuels (natural gas, oil, coal, oilshale), nuclear, solar, wind, geothermal, biomass and wastes, & hydroelectric. Efficiency of the use of these resource are directly related to the location and the demand in that location. For example Hawaii is a prime candidate for the use of the oceans mechanical wave action, the thermal gradient of the ocean, wind, and biomass from the high

There is no question that pollution from automobiles is a major problem in industrialized countries and is increasing in developing nations. And the number of cars is increasingly rapidly: in the United States, the automobile population has increased 6X faster than the human population and 2X faster than the number of new drivers (Motavelli, 2000). At the same time, the average fuel economy of the 2001 fleet decreased to 20.4 miles per gallon, the same it was in 1980. This decrease is fueled by the growing trend in

Demand for gasoline has been the driving force in utilization and depletion of crude petroleum, which is a non-renewable resource. In recent years, tendencies have just begun to, at times, favor alternative fuels to power autos. Many possible alternative fuels exist, certainly not without their drawbacks. These alternatives include, but are not limited to, alcohols, gasohols, and both liquefied and gaseous natural gas, as well as hydrogen. As mentioned above, drawbacks do exist; the chief drawbacks being cost of adaption implementation, engineering, and cost of the fuels themselves. As stated by many a chairman of petroleum companies, alternative fuels have limited applications and too many economic disadvantages,

Since it’s invention and birth in 1886 automobiles have influenced the world in a huge way. It saved people a lot of energy, time and money. Motorized wagons replaced horse carriages and within a few decades Ford started making affordable models of cars with higher efficiency, which revolutionized the concept of transportation. The first ever car that was built was powered by steam. But with development in science and technology other efficient fuel sources were invented. The present day cars run on petrol (gasoline), diesel, and electricity and even sound. With the increased depletion of coal and coal-derived products, the continued use of automobiles is becoming uncertain. Energy

Liquid: state in which matter does not hold a definite shape but occupies a definite volume

Consider the advantages of second law of thermodynamics over first law, this study includes exergy analysis of single cylinder, 4-stroke, water cooled, on a single cylinder 8.1 kW direct injection, diesel engine. In this study first and second laws of thermodynamics ae applied to analyze the quantity and quality of energy in diesel engine cycle. The experimental data were collected using steady state test condition which enables the accurate measurements of air, fuel, and cling water flow rates, engine load, and all relevant temperatures. Each experiment was performed at five different speeds between 1300 rev/min and 2400 rev/min at intervals of 300 rev/min for five different

The advent of stringent emission norms and depletion of fossil fuel resources led the engineers to work out new combustion technologies to substantially reduce harmful emission and to improve the overall efficiency of an IC Engine. Factors to be considered while designing a new combustion process are higher compression ratio, lean homogeneous air fuel mixture and complete combustion and instantaneous combustion, which leads to Homogeneous Charge Compression Ignition (HCCI). HCCI is a clean and efficient combustion process. In this paper an attempt is made to experimentally analyze the performance and emission characteristics of HCCI compression process taking place in Premixed Charge Compression Ignition (PCCI) mode assisted with Pilot Injection as combustion initiator.

The problem with modern combustion engines is that they are very inefficient. Efficiency is defined as the ratio between the amount of input energy against the amount of useful output energy: in this instance, chemical potential energy in the fuel is converted to kinetic energy (initially, driving the pistons upward) which will ultimately go towards giving the car motion. However, only about 25-30% of the energy released from the petrol will go towards actual movement of the vehicle.

With the growing number of vehicle, energy shortage and environmental pollution have become increasingly prominent. Researches on alternative fuels and advanced engine technology have been conducted intensively in recent year to reduce vehicle emission and achieve high engine efficiency. The Homogeneous Charge Compression Ignition (HCCI) combustion engine which operates on lean mixtures and has a gasoline engine-like mixture forming process and diesel engine-like igniting method receives a growing concern.

Significant energy demands related to population growth together with environmental concerns about the effects of fossil fuel usage (e.g., global warming) resulting in more stringent legislation for engine pollutant emissions have been attracting new interest in renewable, sustainable and environmentally friendly energy resources. Many ways have been applied or employed to reduce emissions levels as well as improve engine efficiency. Some fuels additive are being investigated and they have potential of emissions limited to, keeping the extra cost to the minimum as can possible. Alcohol biofuel such as ethanol, butanol are extensively investigated and commercially used. The experimental results revealed that significantly

Petroleum based fuels are producing high emissions in depletion of environment. Due to the usage with modern globalization these emissions causing hazardous for the environment.
