Enhancing fuel burning efficiency by regulate spark plug voltage supply

Nowadays, fuel consumption, fuel efficiency and fuel economy is number one priority for people. The need to reduce fuel consumption is because oil reserves are running low and the cost of gasoline will only increase day by day. The benefits of increased fuel economy is significant energy, cost saving, reducing greenhouse emission, improved air quality and etc. To increase the fuel efficiency, many fuel efficient vehicles was created. Fuel-efficient vehicles are extremely important because we need to cut our fuel consumption and find other way of powering cars. Thus, this research introduced the system that can reduce fuel consumption and improve car performance when the car battery voltage is increase. This system use ac power supply replacing the car battery to get the dc power supply. Also, the system enables to increase voltage from 12 volt to 16 volt supplied to spark plug to enhance fuel burning efficiency. Aims of project are to improve car performance and reduce fuel consumption. To meet the desired aim of this research, the experiment to measure car performance using power performance that are produce from current voltage and the experiment similarly concept with combustion process was done. From that experiment, the system had improved car performance and lessing fuel consumption to 33% when the voltage increases to 16V

Fuel Consumption Tabulation in Laboratory Conditions

Environmental degradation has come about for a number of factors including the use of fossil fuels in vehicles for everyday use. This paper attempts to understand the relationship between fuel consumption and various engine performance parameters under laboratory conditions in order to see how various factors contribute to the overall fuel consumption. The framework for testing has been decided as the New European Drive Cycle (NEDC) given its various testing advantages against other driving cycles. A test rig was applied to simulate the NEDC under laboratory conditions. The findings from this study provide information how vehicular fuel consumption varies with such driving parameters as vehicle speed, acceleration, and throttle position. They can be used to predict fuel consumption under any real life driving conditions, which will contribute to reducing fuel consumption in future vehicle desig

Real-world comparison of probe vehicle emissions and fuel consumption using diesel and 5 % biodiesel (B5) blend.

An instrumented EURO I Ford Mondeo was used to perform a real-world comparison of vehicle exhaust (carbon dioxide, carbon monoxide, hydrocarbons and oxides of nitrogen) emissions and fuel consumption for diesel and 5% biodiesel in diesel blend (B5) fuels. Data were collected on multiple replicates of three standardised on-road journeys: (1) A simple urban route; (2) A combined urban/inter-urban route; and, (3) An urban route subject to significant traffic management. At the total journey measurement level, data collected here indicate that replacing diesel with a B5 substitute could result in significant increases in both NOx emissions (8-13%) and fuel consumption (7-8%). However, statistical analysis of probe vehicle data demonstrated the limitations of comparisons based on such total journey measurements, i.e., methods analogous to those used in conventional dynamometer/drive cycle fuel comparison studies. Here, methods based on the comparison of speed/acceleration emissions and fuel consumption maps are presented. Significant variations across the speed/acceleration surface indicated that direct emission and fuel consumption impacts were highly dependent on the journey/drive cycle employed. The emission and fuel consumption maps were used both as descriptive tools to characterise impacts and predictive tools to estimate journey-specific emission and fuel consumption effects

Drive Cycle Optimisation for Pollution Reduction

Green house gas emissions have abraded environmental quality for human existence. Automobile exhaust is a significant contributor globally to green house gases, among other contributors. This research investigates how vehicle fuel consumption can be tabulated from laboratory tests and road tests. The laboratory tests are used to establish mathematical relationships to predict fuel consumption as a function of such drive-cycle parameters as vehicle speed,acceleration and throttle position. Then, these relationships are applied to calculate fuel consumption during real-life road tests. In the future, the drive-cycle parameters contributing to vehicle fuel consumption could be optimized to lower automobile exhaust’s impact on environmental degradation

Predicting fuel energy consumption during earthworks

This research contributes to the assessment of on-site fuel consumption and the resulting carbon dioxide emissions due to earthworks-related processes in residential building projects, prior to the start of the construction phase. Several studies have been carried out on this subject, and have demonstrated the considerable environmental impact of earthworks activities in terms of fuel consumption. However, no methods have been proposed to estimate on-site fuel consumption during the planning stage. This paper presents a quantitative method to predict fuel consumption before the construction phase. The calculations were based on information contained in construction project documents and the definition of equipment load factors. Load factors were characterized for the typical equipment that is used in earthworks in residential building projects (excavators, loaders and compactors), taking into considering the type of soil, the type of surface and the duration of use. We also analyzed transport fuel consumption, because of its high impact in terms of pollution. The proposed method was then applied to a case study that illustrated its practical use and benefits. The predictive method can be used as an assessment tool for residential construction projects, to measure the environmental impact in terms of on-site fuel consumption. Consequently, it provides a significant basis for future methods to compare construction projects.Peer ReviewedPostprint (author's final draft

The role of technology as air transportation faces the fuel situation

Perspectives on the air transportation fuel stituation are discussed including intercity air traffic, airline fuel consumption, fuel price effects on ticket price, and projected traffic and fuel useage between now and the year 2000. Actions taken by the airlines to reduce consumption are reviewed, as well as efforts currently underway to improve fuel consumption. Longer range technology payoffs resulting from NASA research programs are reviewed and results from studies on the use of alternate fuels are discussed

The impacts of air-pollution motivated automobile consumption tax adjustments of China

A concomitant of the rapid development of the automobile industry in China is the serious air pollution and carbon dioxide emission. There are various regulation instruments to reduce the air pollution from automobile sources. China government chooses a small-displacement oriented consumption tax as well as fuel tax to alleviate the worse air pollution. This paper evaluates the effects of both policy instruments on fuel consumption and social welfare. Our empirical results show that fuel tax decreases the total sale of new cars, which leads to a decline of total consumption of fuel from the new cars, but does not change the sale distribution over various fuel efficiency models; while consumption tax adjustment results in a skewed sale distribution toward more efficient new cars but increases the total consumption of fuel due to an enlarged sale. The effects of these two taxes on pollution depend on our assumption about the average fuel efficiency of outside goods. On the other hand, consumption tax leads to less social welfare loss; in particular, consumer surplus decreases in an order of magnitude less than that caused by fuel tax. Fuel tax actually transfers more welfare from private sector to the government.China auto industry, welfare analysis, tax incidence, BLP model, tax progressivity
