Fast depletion of the conventional petroleum-based fossil fuel reserves and the detrimental effects of the pollutant emissions associated with the combustion of these fuels in internal combustion (IC) engines propelled the exploration and development of alternative fuels for internal combustion engines. Biodiesel has been identified as one of the most promising alternative fuels for IC engines. This paper discusses about the advantages and disadvantages of biodiesel vis-a-vis the conventional petro-diesel and presents the energetic performances and emission characteristics of CI engine using biodiesel and biodiesel-petrodiesel blends as fuels. An overview of the current research works carried out by several researchers has been presented in brief. A review of the performance analysis suggests that biodiesel and its blends with conventional diesel have comparable brake thermal efficiencies. The energy balance studies show that biodiesel returns more than 3 units of energy for each unit used in its production. However, the brake specific fuel consumption increases by about 9–14% compared to diesel fuel. But, considerable improvement in environmental performance is obtained using biodiesel. There is significant reduction in the emissions of unburned hydrocarbons, polyaromatic hydrocarbons (PAHs), soot, particulates, carbon monoxide, carbon dioxide and sulphur dioxide with biodiesel. But the NOx emission is more with biodiesel compared to diesel. A case study with Jatropha biodiesel as fuel and the current development status, both global and Indian, of biodiesel as a CI engine fuel have been included in the paper.

The recent transport electrification trend is pushing governments to limit the future use of Internal Combustion Engines (ICEs). However, the rationale for this strong limitation is frequently not sufficiently addressed or justified. The problem does not seem to lie within the engines nor with the combustion by themselves but seemingly, rather with the rise in greenhouse gases (GHG), namely CO2, rejected to the atmosphere. However, it is frequent that the distinction between fossil CO2 and renewable CO2 production is not made, or even between CO2 emissions and pollutant emissions. The present revision paper discusses and introduces different alternative fuels that can be burned in IC Engines and would eliminate, or substantially reduce the emission of fossil CO2 into the atmosphere. These may be non-carbon fuels such as hydrogen or ammonia, or biofuels such as alcohols, ethers or esters, including synthetic fuels. There are also other types of fuels that may be used, such as those based on turpentine or even glycerin which could maintain ICEs as a valuable option for transportation.

Stroke Engine

The requirement for the advancement of internal combustion (IC) engines and enhance methods for the combustion cycle is increasing day by day. The four-stroke combustion engine is extensively used due to better fuel economy and less exhaust smoke. However, the major drawback includes a considerable amount of extra heat energy generation that directly adds up to waste energy. In order to overcome the limitation, the idea of computing two extra strokes in the four-stroke engine to utilize the waste energy has been introduced. The six-stroke engine has significantly improved the fuel working ratio per cycle. Incorporating alternative fuels like hydrogen and HHO into six-stroke technology increases efficiency and minimizes exhaust emissions. A six-stroke engine could be the solution for making hybrid automobile technology more convenient. The review article aims to thoroughly understand the underlying principles behind the improved efficiency of a six-stroke cylinder engine. The researches on the six-stroke cylinder engine are summarized in the literature review. The design configuration of alternative fuels is discussed towards the end of the paper.

Ic Engines

The populace in the global scenario has drastically increased in the past decades. Due to this situation, the necessity of transportation also escalated which simultaneously raised the pollution levels. Nowadays the populace commonly prefers their individual vehicles rather than public transport system. This made the automotive manufacturers to come up with new technologies and to compensate the stringent norms introduced by several countries. Internal Combustion engine has been serving the world more than a century and plays a vital role in the means of transportation. Many types of research were made to enhance the efficiency of IC engines by the use of alternative fuels, alteration of the intake parameters, stroke variation, usage of alternative materials etc., At present scenario of IC engine, the efficiency ranges between 35 – 50 % based on the technology used. If more efficient IC engines are used it would meet the demand of depleting fossil fuels. Such engines may prevent the demise of fossil fuels. Thus our project deals with the prospect to discuss the phenomenal changes and effects occurring on IC engine when the working fluid is enriched oxygen.

For the municipal solid waste (MSW) to be used in a proper way, it is necessary to implement clean technologies capable of thermal treatment of MSW and RDF in order to produce heat and electricity while meeting current ecological requirements. Nowadays, a number of technologies for MSW/RDF thermal treating are being used worldwide. Among them, the most proven technologies, applicable for industrial introduction, have been considered while analyzing their advantages/ disadvantages accounting for local conditions of Ukraine.
