This paper explores the feasibility and sensitivity of a mileage-based road usage charge (RUC) as an alternative to the gas tax. The specific purpose is to evaluate factors that could be considered when setting a charge to account for the complex makeup of statewide motor fleets, and to consider the diversity of household driving behaviors and experiences. The researchers considered a range of potential parameters before choosing to focus on fuel type and fuel efficiency. If based on annually adjusted efficiency quantiles, a parameterized RUC could prevent revenue erosion over time. Formulas based on these parameters were compared with the current fuel excise tax and a flat RUC. Distributional effects of parameters were assessed for urban, mixed, and rural household categories, and for vehicles of different fuel types. Results show that households in urban tracts tend to pay slightly more under all formulations, and households in mixed and rural tracts pay less compared with an excise-based gas tax. In addition to changes across regions of a state, the method allows examination of the groups within these categories. Research found that adjusting for fuel efficiency reduced the change in incidence between urban, mixed, and rural census tracts, and between fuel types, that results from moving to a flat RUC. Fuel type parameters resulted in only small differences from the flat rate RUC because of low alternative fuel penetration in most states. This may change over time depending on the rate of integration of alternative fuels into the passenger car fleet.

The influence of the circuitry of the hybrid power plant short and medium haul aircraft on their fuel efficiency and environmental characteristics have been investigated. Directions of improvement of traditional patterns of power plants of aircraft on the example of PD-14 engine were analyzed. It has been shown that the use of turbojet engines and traditional schemes operating on aviation kerosene, will not allow to fulfill the demands made by the International Civil Aviation Organization (ICAO) to perspective plane 2025–2035. The analysis of the three schemes hybrid propulsion systems has been performed. It has been shown that using the presented hybrid propulsion systems of alternative fuels can reduce CO2 emissions by 19% to 20% compared with conventional turbojet engines, which run on kerosene TS-1. It has been shown that this fuel efficiency is increased by 2–3%, and the total mass of the power plant increases of 6 to 16%.

Eco Features

Objective: The objective of the present research was to understand drivers’ interaction patterns with hybrid electric vehicles’ (HEV) eco-features (electric propulsion, regenerative braking, neutral mode) and their relationship to fuel efficiency and driver characteristics (technical system knowledge, eco-driving motivation). Background: Eco-driving (driving behaviors performed to achieve higher fuel efficiency) has the potential to reduce CO2 emissions caused by road vehicles. Eco-driving in HEVs is particularly challenging due to the systems’ dynamic energy flows. As a result, drivers are likely to show diverse eco-driving behaviors, depending on factors like knowledge and motivation. The eco-features represent an interface for the control of the systems’ energy flows. Method: A sample of 121 HEV drivers who had constantly logged their fuel consumption prior to the study participated in an online questionnaire. Results: Drivers’ interaction patterns with the eco-features were related to fuel efficiency. A common factor was identified in an exploratory factor analysis, characterizing the intensity of actively dealing with electric energy, which was also related to fuel efficiency. Driver characteristics were not related to this factor, yet they were significant predictors of fuel efficiency. Conclusion: From the perspective of user–energy interaction, the relationship of the aggregated factor to fuel efficiency emphasizes the central role of drivers’ perception of and interaction with energy conversions in determining HEV eco-driving success. Application: To arrive at an in-depth understanding of drivers’ eco-driving behaviors that can guide interface design, authors of future research should be concerned with the psychological processes that underlie drivers’ interaction patterns with eco-features.

Transport Modes

Before proceeding to explore potential strategies for energy conservation in urban passenger transport, this paper presents some evidence on energy efficiencies of various transport modes and on travel behaviour under energy constraints. Knowledge of the relative energy efficiencies of different modes of transport is evidently necessary for analysing and developing policies for fuel conservation. Although the automobile does appear to be significantly more energy-intensive than public transport modes, this does not automatically indicate that a policy to attract people to public transport would lead to the maximum possible fuel savings. Available evidence on travel behaviour under energy constraints indicates that the elasticity of travel demand is very small. Increasing prices, within the range expected, are not likely to result in satisfactory fuel savings, and it is therefore necessary to consider alternative strategies. The strategies to be considered here may be outlined as follows: (1) improving fuel efficiency of automobiles by modifying driving habits, reducing speeds, improving traffic flows, and keeping vehicles properly maintained; (2) increasing efficiency of automobile travel by promoting higher occupancies; (3) attracting car travellers to public transport; (4) shifting to smaller, more fuel-efficient vehicles, changing vehicle and engine designs such as to improve the inherent fuel efficiency of the automobile; (5) technological change: new propulsion systems, alternative fuels, and rapid personal transport; (6) reducing travel needs by changing land-use patterns and improving communications. These strategies are discussed in turn and, given the available information about travel patterns and behaviour, an attempt is made to assess their likely impact. Clearly those strategies should be selected which offer the maximum potential fuel savings and which can be introduced with minimum sacrifice.

Fuel Taxes

Inflation and improved fuel economy have undermined revenue from federal and state excise taxes on gasoline and diesel; this situation has made it challenging to maintain and expand the nation's road network. With more stringent federal fuel economy standards and the emergence of alternative fuels threatening to accelerate this problem in future years, policymakers have begun to explore mileage-based user fees as a long-term replacement for fuel taxes. Unaffected by fuel type or fuel economy, mileage fees would provide more sustainable revenue, and the system could be structured to promote more efficient use of the roads, offer value-added motorist services, and collect travel data to support better network planning and operations. Mileage fees will likely cost more to administer than will fuel taxes, however, and the concept faces acceptance challenges related to privacy protection and other concerns. These obstacles in turn have spurred great innovation. On the basis of recent studies, trials, and implementation efforts, this paper presents a review of promising mileage-fee design and implementation strategies intended to reduce system costs and foster greater public acceptance.

Abstract Under the Federal Aviation Administration’s (FAA) Aviation Climate Change Research Initiative (ACCRI), non-CO2 climatic impacts of commercial aviation are assessed for current (2006) and for future (2050) baseline and mitigation scenarios. The effects of the non-CO2 aircraft emissions are examined using a number of advanced climate and atmospheric chemistry transport models. Radiative forcing (RF) estimates for individual forcing effects are provided as a range for comparison against those published in the literature. Preliminary results for selected RF components for 2050 scenarios indicate that a 2% increase in fuel efficiency and a decrease in NOx emissions due to advanced aircraft technologies and operational procedures, as well as the introduction of renewable alternative fuels, will significantly decrease future aviation climate impacts. In particular, the use of renewable fuels will further decrease RF associated with sulfate aerosol and black carbon. While this focused ACCRI program effort has yielded significant new knowledge, fundamental uncertainties remain in our understanding of aviation climate impacts. These include several chemical and physical processes associated with NOx–O3–CH4 interactions and the formation of aviation-produced contrails and the effects of aviation soot aerosols on cirrus clouds as well as on deriving a measure of change in temperature from RF for aviation non-CO2 climate impacts—an important metric that informs decision-making.

AbstractThis study quantifies the possible consequences to stakeholders of reforms to the excise tax on reversions of excess pension assets. Under the US Pension Protection Act (PPA) of 2006, funding in defined benefit (DB) plans is likely to improve significantly. Many plans may become overfunded over time, owing to the shortfall amortizations mandated by the PPA, as well as to precautionary contributions by sponsors and to plan investment returns. This analysis shows that a more moderate excise tax rate together with a reasonable funding threshold for asset reversions would not only enable sponsors to spend the excess funds on other corporate needs, thereby lowering the cost of sponsorship of DB plans, but also would open a considerable revenue source for the government, with only a small increase in bankruptcy cost for the PBGC. Plan participants could also gain in an alternative reform, which would require a partial transfer of excess assets to them along with a still-lower reversion tax rate. These findings also hold for plan sponsors with various degrees of risk tolerance or only making the PPA-required minimum contributions.

Ethanol Steam

The means of transportation that are widely used in Indonesia are vehicles in the form of motorbikes and cars, as well as the increasing dependence on the consumption of fuel oil (BBM).  The impact is that the need for fuel oil is also high.  As a result of dependence on fossil energy this one increases.  Based on the problems that have been raised, a concept has emerged to make alternative fuels that can be used as a fuel mixture or as an alternative to these fuels.  One of the renewable energy sources that can be utilized is ethanol which comes from corn, wheat, and others.  ethanol vapor as a fuel mixture, where the ethanol used is not mixed directly into the fuel.  And by utilizing ethanol vapor, it is also expected to increase the performance and efficiency of motorbikes.  In this study we used a reference concept which was then used as a concept, how to influence additional ethanol vapor temperature variations on the use of pertalite fuel on the performance and efficiency of 4-stroke motorbikes using temperature variations of 400C, 500C, and 600C and variations of valve openings  on the ethanol vapor hose to the intake manifold.  After conducting the test, the results show that the best power is obtained from the addition of ethanol steam at a temperature of 450 full openings when it is at 7973 RPM rotation which shows a power of 31.2 HP and when it is at 5757 RPM rotation which shows a torque of 32.24 N.m.  The best fuel efficiency is obtained from the addition of ethanol steam with a temperature of 450 full openings with a fuel consumption of 1 liter only reduced by 75 ml every 5 minutes of use at the same speed.

This article describes the power train design specifics in Formula student race vehicles used in the famed SAE India championship. To facilitate the physical validation of the design of the power train system of a formula student race car category vehicle engine of 610 cc displacement bike engine (KTM 390 model), a detailed design has been proposed with an approach of easing manufacturing and assembly along with full-scale prototype manufacturing. Many procedures must be followed while selecting a power train, such as engine displacement, fuel type, cooling type, throttle actuation, and creating the gear system to obtain the needed power and torque under various loading situations. Keeping the rules in mind, a well-suited engine was selected for the race track and transmission train was selected which gives the maximum performance. Based on the requirement, a power train was designed with all considerations we need to follow. Aside from torque and power, we designed an air intake with fuel efficiency in mind. Wireless sensors and cloud computing were used to monitor transmission characteristics such as transmission temperature management and vibration. The current study describes the design of an air intake manifold with a maximum restrictor diameter of 20 mm.
