Day By Day

The world is passing through a phase of sustainable modernization and industrial development day by day. As a result, there is an increasing number of vehicles used and heat engines demands in the market. However, energy sources used in these engines are limited and decreasing gradually. This situation leads to evolution of alternative sources to viable fuel for diesel engine. Biodiesel is seen as an alternative fuel for diesel engine combustion.  The esters of vegetable or plant oil and animal fats are known as biodiesel. This article investigates the prospect of producing biodiesel from Jatropha oil. Jatropha curcas oil is a renewable non-edible plant. The seeds of Jatropha contain 50-60% oil. In this study, the oil has been converted to biodiesel by a well-known two-step, acid-base catalytic transesterification and used in diesel burner for performance evaluation. Biodiesel used in this study is a blend of diesel and Jatropha biodiesel. The performance of burner system using Jatropha biodiesel is based on its temperature profile and emissions generated such as nitrous oxide (NOx), sulphur dioxide (SO2) and carbon monoxide (CO).  A reduction of 50% was achieved for both CO dan SO2 when burning Jatropha biodiesel compared to burning diesel.

The depletion of oil fields and the deteriorating environmental situation leads to the need for the search of new alternative sources of energy. Actuality of the article due to the need for greater use of the alternative fuels in internal combustion engines is necessary. Fuels produced from vegetable oils and animal fats as advanced alternative fuels for diesel engines are considered. These fuels are produced from renewable raw materials and are characterized by good environmental qualities. Advantages of using fuels of vegetable origin as motor fuels are shown. Experimental research of diesel engine D-245.12S functioning on mixtures of diesel fuel and mustard oil of various percentage is given. One of the most wide spread vegetable oils in Russia is mustard oil. Possible ways of using mustard oil as fuel for a diesel engine are considered. An opportunity of improving characteristics of exhaust gases toxicity by using these mixtures as a fuel for automobile and tractor diesel engines is demonstrated.

Exhaust Noise

In order to obtain the foundation to the research on the Diesel Engine YN4100QB combustion process, exhaust, the optimal design of combustion chamber and the useful information for the design of exhaust muffler, the geometric model and mesh model of a type internal combustion engine are constructed by using FIRE software to analyze the working process of internal combustion engine. Exhaust noise is the main component of automobile noise in the study of controlling vehicle noise. It is primary to design a type of muffler which is good for agricultural automobile engine matching and noise reduction effect. The present car mufflers are all development means. So it is bound to cause the long cycle of product development and waste of resources. Even sometimes not only can it not reach the purpose of reducing the noise but also it leads to reduce the engine dynamic. The strength of the exhaust noise is closely related to engine combustion temperature and pressure. The calculation and initial parameters are applied to the software based on the combustion model and theory. According to the specific operation process of internal combustion engine. Five kinds of common operation condition was compiled. It is obtained for the detailed distribution parameters of combusted gas temperature pressure . It is also got for flow velocity of the fields in cylinder and given for the relation of the parameters and crankshaft angle for the further research. At the same time NOx emissions situation are got. The numerical results show that not only does it provide the 3D distribution data in different crank shaft angle inside the cylinder in the simulation of combustion process, but also it provides a basis for the engine combustion ,emission research, the optimization design of the combustion chamber and the useful information for the designs of muffler.
