As the global shortage of oil resources and the rapid increase in car ownership, using gas as the alternative fuel is getting more and more important. Gas fuel, such as CNG (compressed natural gas)/LNG (liquefied natural gas) and LPG (liquefied petroleum gas), with resource-rich, less pollution and other features, are desirable alternative fuels for cars. Through engine bench test, a comparative analysis of power performance between LPG-single fuel engine and gasoline engine was done. The result shows that, by applying LPG injection on single-fuel engine, the power of the LPG engine increases to a higher level than gasoline engines. And combined with the analysis based on the study of domestic development of NGV, predictions could be made that new fuel vehicles will be well utilized in future.

As the global shortage of oil resource and the rapid increase in car ownership, using gas as the alternative fuel is getting more and more important. Gas fuel, such as LNG (liquefied natural gas), with resource-rich, less pollution and other features, is desirable alternative fuels for cars. In this article, through the engine bench test, a comparative analysis of power performance, fuel economy, emission between diesel/LNG dual engine and diesel engine was done. The result shows that, compared to the original machine , power performance of modified diesel / LNG dual fuel engine decline but isnt obvious. At the same time , fuel economy has a substantial increase. The use of natural gas can relieve shortage of global oil resource and the supply-demand imbalance of oil products. The emission of modified diesel / LNG dual fuel engine has a better state than that of original machines. This kind of modified dual fuel engine is simple, low cost, easily promoted and will be well utilized in future.

Emissions are reported for four heavy-duty trucks, which were converted to operate on compressed natural gas fuel. Two 1988 model year Ford F700 Series trucks equipped with 7.0 L gasoline engines and two 1986 model year GMC trucks equipped with DDC 8.2 L diesel engines were tested on a heavy-duty chassis dynamometer in a baseline condition and again after conversion to natural gas. The vehicles were tested over the EPA Urban Dynamometer Driving Schedule for Heavy-Duty Vehicles and at no-load curb idle. Regulated emissions of NOx, CO, HC, and diesel particulate, along with nonmethane hydrocarbons, are reported in grams/mile. Fuel economy is reported in energy-equivalent miles per gallon of gasoline or diesel fuel.

Engine bench test research has been done on a JL4JB1 diesel engine fueled with compressed natural gas (CNG), and the power performance, load performance and universal performance were obtained, analyzing the performance changing regulations of CNG engine. The results indicate that the maximum torque turns up at the medium speed when the engine operates at power performance points, and the minimum brake specific gas consumption (BSGC) also comes up at medium speed. When the rotating speed keeps constant, BSGC decreases with the torque increasing, and decreasing largely at small load while a little at high load. From the universal performance curve of CNG engine, we can know that the minimum BSGC is 194g/kW·h.

Abstract In this paper, the analysis of alternative fuels is carried out: electricity, hydrogen, biofuels (bioethanol, biodiesel, biogas), solar energy, compressed air, gas engine fuel (compressed natural gas, liquefied petroleum gas, liquefied natural gas). The advantages and disadvantages of their use are indicated according to the criteria of environmental safety, cost, and infrastructure development. It is revealed that at the moment, gas-engine fuel, in particular liquefied petroleum gas and compressed natural gas, is most suitable for the transfer of the fleet. The economic and environmental effect of the market expansion is associated with the high environmental friendliness of this type of fuel, low price, large natural reserves, the development of the petrochemical industry of the country, the reduction of financial costs for the repair and reconstruction of physically and morally outdated oil refining and liquid fuel production enterprises, promising technical and technological solutions to transport problems.

<p>Liquefied Petroleum Gas (LPG) usage is liquefied petroleum gas which being melted by adding pressure and lowering the temperature, then the gas will turn into liquid. Butane (C4H10) and propane (C3H8) are the dominating components. The need for Liquefied Petroleum Gas (LPG) especially for the household sector is more effective when using the complement of 3 kg of LPG. Gas fuel for transportations is more suitable when using Compressed Natural Gas (CNG), which is a compressed natural gas as gas fuel. It is considered cleaner and environment friendly than gasoline and diesel fuel because of the gas emissions waste. This CNG is made by compressing methane (CN4) extracted from natural gas then stored and distributed in a pressure pneumatic. Gas for fuel will increase the engine workload, so it tends to increase the consumption of the fuel. However, the gas low pressure on the transportation sector can decrease the compression on the machines. It will reduce the capital up to 50%.</p><p><strong><em>Keywords :</em><em> Gas, Alternative, Ship’s Propulsion</em></strong></p><p> </p><p>Pemakain Gas Liquified Petroleum Gas (LPG)  yaitu gas minyak bumi yang dicairkan  dengan menambah tekanan dan menurunkan suhunya, gas akan berubah menjadi cair.

Abstract Radon (222Rn) exposure in the environment is an important issue, and many pathways exist for radon exposure to humans. One of these pathways is 222Rn release through the consumption of natural gas. The issues of 222Rn concentration measurement techniques and worldwide concentration distribution were reviewed in natural gas, with emphasis on performing an active method to determine 222Rn concentration in LPG and CNG gases used in Cyprus. The obtained results were compared with 222Rn concentration in natural gas worldwide and UNSCEAR reports. The average 222Rn concentration value in LPG gas was observed higher than CNG gas. Also, the 222Rn concentration in LPG and CNG gases was less than the UNSCEAR reported value.

Ever since the energy crises in 1970s, the methanol, among other alternative fuels, has been studied for automotive application. The methanol has been widely used for auto racing due to its superior anti-knock characteristics. However, aldehyde is a highly toxic pollutant and aldehyde emission out of alcohol fuel combustion could be considerably higher than spark-ignited gasoline engines. The corrosion and durability of methanol fuel components were also concerns for mass production of methanol-fueled vehicles. The authors have worked with an automotive manufacturer in China to investigate the brake thermal and emission improvement potentials of a methanol-fueled, spark-ignited engine over the original gasoline engine on a passenger car application and to demonstrate the performance and China V emission compliance over its useful life of 160,000 km. The study found that the methanol-fueled engine has 4%–6% brake thermal advantage over the original gasoline engine, and a three-way oxidation catalyst has successfully managed the tailpipe emissions under China V emission limit, consistently over the journey of 160,000 km. The test data show that the tailpipe aldehyde emission is actually reduced to a level that is below what is required by US LEV III emission standard, largely due to the three-way oxidation catalyst and the gasoline cold start assistance at the beginning of the transient emission cycle. This study indicates that methanol-fueled engine might be an attractive low-cost alternative for a more efficient and clean powertrain over conventional gasoline when a light-duty diesel engine faces challenges from future China VI emission regulations.
