The market of the hybrid electric vehicles has been increasing for several years. Different commercial EV and PHEV solutions are available for passenger cars and light vehicles for freight deliveries. However, the market of heavy trucks still regards traditional ICE vehicles powered by diesel oil fuel. The recent interest for electric solutions have been pushing the development of the hybrid solutions, but only micro-hybrid systems are considered feasible for heavy truck applications. The proposed research aims to define a methodological approach with a virtual model in order to simulate the behavior of a hybrid heavy truck. The scope of this research is the feasibility analysis of a retrofit hybrid heavy truck. A real driving cycle has been used in order to obtain reliable results in terms of cost, energy consumption and gas emission. The layout of the hybrid system has been proposed as well as the sizing of battery and electric motor. A commercial tool has been used for the vehicle modelling and simulation. As a test case, an 18-ton truck has been analyzed with a 10-liter diesel engine. Firstly, the simulation of the diesel truck has been reproduced considering the real driving cycle data. Secondly, the simulation activity has been focused on the evaluation of the hybrid system behavior by investigating different battery sizes with the same boundary conditions related to the real driving cycle.

Indonesia which is a net-exporter in of fuel oil has turn become a net importer of oil since 2009. It is ironic because it occurs at the world's oil price is unstable and tends to increase. It is time for Indonesia to develop alternative energy sources and bio-diesel oil from the seeds of  nyamplung (Calophylum inophylum L.). The purpose of this researh was to determine the magnitude of the yield of oil from the seeds of the produced by the level of maturity. The raw and the riped yamplung seeds was used in this research. The results showed that the yield of oil in ripe seed is 24.01% and the raw one is 19.17% . Acid number and iodine number of oil based on the average maturity are 37.51 g / ml and 3094.14 g / ml for the ripe fruit, and 37.18 g / ml and 3421.32 g / ml for the raw fruit.Keywords: nyamplung, maturity, yield, oil, fuel.

ALSTOM Power has launched the GT10C a 30 MW industrial gas turbine (see figure 1) upgraded from the 25 MW GT10B. The thermal efficiency of the new gas turbine is 37.3% (shaft) and 36% electrical at ISO inlet conditions with no losses. The new GT10C has a Dry Low Emission (DLE) combustor for both natural gas and diesel oil fuel; it has NOx emissions at 15 ppmv on gas and 42 ppmv on oil fuel (15% O2 dry). The first GT10C is now manufactured and assembled, and has been under testing since October 2001. For this purpose a new test rig has been built in Finspong, Sweden, in order to verify performance and reliability. GT10C will be available to the market mid-2002 and manufactured in parallel with GT10B. The general design is based on the GT10B and measures have been taken for maximum reliability and maintenance in order to keep operation costs to a minimum. Improvements for GT10C are mainly derived from GT10B or taken from ALSTOM Power GTX100 (43 MW gas turbine), as described herein.

This paper describes the development history of the CW352 engine combustor from the time when the persistent problem of a hot primary zone wall when operating in the regenerative mode while burning diesel oil was solved by the incorporation of an airblast atomizer. The problems of stability and poor atomization at low engine cranking speeds which accompany the use of airblast atomizers were addressed in the combustion laboratory but evaluation tests on an engine showed that further improvement in these areas would be beneficial. Concurrently, the preliminary design strategy of the CW182 combustor was predicted on the use of an airblast atomizer and its development program emphasized a phase of testing which examined the effects on nozzle performance of variations in local flowfield and of the use of atomizing air. The paper documents the particular problems met and solved in the areas of burning oil fuel in a regenerative machine, of maintaining low emissions of smoke while designing for single inventory of parts and providing stable combustion by the use of auxiliary atomizing air.

Oil Fuel

As a developing country, currently the energy demand in Indonesia increases rapidly.Although Indonesia has a huge of oil reserves the production of oil fuels as the main energy consumption has not been enough and should be imported. It is devised to substitute oil fuel with other resources such as liquefied coal, natural gas, biofuels and dimethyl ether (DME). In the short future, the use of DME as an alternative fuel appears to be a promising approach for reducing the uses of diesel oil and LPG. It can be described in to two approaches. First, due to the high cetane number of DME, it can be used for compression ignition engines which have higher thermal efficiencies compared to spark ignition engines. Second, due to the physical properties of DME, it can substitute oil fuels and LPG uses in industries, commercials, and households for lighting and cooking. Hence, DME production is not limited to one feedstock. DME canbe derived from fossil fuel feedstocks, including natural gas and coal, as well as from renewable feedstock sources such as biomass. Since Indonesia have abundant of energy sources as DME raw material, such as natural gas, coal and biomass, utilization of DME into Indonesia energy system is necessary to be developed.Key words :Energy Potential, Dimethyl Ether, Diesel Oil and LPG Substitution

Hydrotreating process of Sunan candlenut oil by using NiMo-γAl2O3 catalyst has been successfully investigated. Preparation of NiMo-γAl2O3 catalyst by using dipping impregnation method generated catalyst used for hydrotreating process. This method consists of three stages: support activation, impregnation, and calcination. This factors influencing the process including temperature, pressure, and the ratio of Sunan candlenut oil to the H2 gas factor were examined. The hydrotreating product of fuel similar to oil was obtained at a minimum temperature of 380 °C, a pressure of 30–60 bar, and the ratio of the sample to H2 gas of 0.5–1. The diesel fuel from physical properties range for the density of 0.82–0.86 g/cm3, and kinematic viscosity of 2–6 cSt have been fulfilled by hydrotreating result. Gasoline, naphtha, diesel oil, and gas oil products of Sunan candlenut oil were obtained by distillation from hydrotreating process. Sunan candlenut oil fuel qualified fuel requirement.

In this paper, we present the estimate and results of measurement of air pollution in Béjaia city in Algeria. We used an enclosure of 0,80 m3 for the collection of gases directly on the outlet side of the tailpipe of the vehicles. A three-gas detector (MX21 plus), introduced inside the enclosure, measures the rates of carbon monoxide CO, sulphur dioxide SO2 and nitric monoxide NO. We studied the exhaust pollutants according to the age of the vehicle (1980 – 2004) and the acceleration of the engine. Measurements related to a sample of 204 vehicles using gasoline or diesel oil fuel. The comparison between the rejections and the standards European, American and Japanese norms encourages us to challenge the authorities on the urgency of the introduction of the vehicle inspection and technical control. Except the new vehicles (less than 5 years old), where the results are comparable, the others exceed largely the standards. We have counted the number of vehicles passing through the Daouadji square during one month (March 2004) and calculated the total pollution rejected. The comparison with the air pollution measured in situ confirmed that urban pollution is primarily from automobile sources. On the curve of the weekly evolution of the air pollution the days and peak hours of the automobile traffic appear clearly. The correlation with the number of vehicles is very significant (0,78). By taking account of the annual rate of increase in the number of vehicles and keeping the current park without adequate maintenance, a statistical model envisages an unbearable urban pollution near 2010.
