2004-28-0039
As neat crude palm oil is not ideally suitable as a fuel for diesel engines because of its high viscosity; process of transesterification was adopted to develop methyl ester of palm oil that approximate the properties and performance of hydrocarbon-based diesel fuel. Various properties of the methyl ester of palm oil were evaluated and compared in relation with that of neat diesel. The prepared methyl ester of palm oil, blended in different concentrations with neat diesel was then subjected to performance and emission tests in order to evaluate its suitability in diesel engine. The data thus generated were compared with base line data generated from neat diesel. An optimal blend of 10-20% methyl ester of palm oil with neat diesel exhibited best performance and smooth engine operation without any symptoms of undesired combustion phenomenon. This suggests use of 10-20% of biodiesel developed from palm oil in diesel engine with out any difficulty.

Internal combustion engines are extensively used in every field of life in today's world. Diesel engines being more efficient are preferred in the industrial and transportation sector in comparison to spark ignition engines for their higher efficiency, versatility and ruggedness. The major emissions of diesel engines are oxides of nitrogen (NOx), particulate matter (PM), carbon dioxide (CO2), carbon monoxide (CO). Among these emissions, oxides of nitrogen (NOx) and the particulate matter are the reasons of serious concern. For reduction of oxides of nitrogen (NOx) and particulate matter simultaneously, the use of Homogeneous Charge Compression Ignition (HCCI) have provided a sustainable solution in the present scenario. Further, the use of CNG in HCCI engine along with pilot diesel injection; the emissions have been decreased drastically. Homogeneous mixing of fuel and air leads to cleaner combustion and lower emissions.

It is of common knowledge that tapping all the feasible sources of energy and systems which prevent losses is the need of the hour. Currently, many such systems have been developed including “REGENERATIVE BRAKING”. The usual method for regenerative braking includes using a dynamo attached to the crankshaft which gets charged when the wheel rotates during idling. However, this study aims at doing this differently by attaching the regenerative system at the wheels. Considering an example of wastage of energy, a 1000 kg car brakes from 36km/h (10m/s) to 18km/h (5m/s) about 150 times in a liter consumption of diesel. We can safely calculate wastage of 5625 KJ of kinetic energy. This paper aims to explore this immense potential source of energy recovery by producing & storing electricity using magnetic braking on wheels of automobiles.

The increment in the application of fossil fuels is leading the world into a catastrophic state both environmentally and economically. Current demand for fuels exceeds its imminent supply and rather sooner than later energy demands will have to shift towards non-conventional fuels to cope with the situation. With constant developments in the automotive sector, several solutions have been found but none have been as good as gasoline to substitute it in the commercial market. One such solution being compressed air might solve this global fuel crisis, which serves a glowing advantage of being cheaper and greener as it produces zero tail-pipe emissions, and can help in decreasing automobile’s contribution to global warming. Though the potential energy stored in the compressed air limits its application to light duty vehicles and still there will be a need for other alternative solutions for the heavy duty vehicles in order to relieve the pressure from the fossil fuels.

The diesel engine has for many decades now assumed a leading role in both the medium and medium-large transport sector due to their high efficiency and ability to produce high torque at low RPM. Furthermore, energy diversification and petroleum independence are also required by each country. In response to this, biodiesel is being considered as a promising solution due to its high calorific value and lubricity conventional petroleum diesel. However, commercial use of biodiesel has been limited because of some drawbacks including corrosivity, instability of fuel properties, higher viscosity, etc. Biodiesel are known for lower CO, HC and PM emissions. But, on the flip side they produce higher NOx emissions. The addition of alcohol to biodiesel diesel blend can help in reducing high NOx produced by the biodiesel while improving some physical fuel properties.

The crankshaft translates the reciprocatory motion of the piston into rotary motion. A flywheel is generally connected to the crankshaft to reduce the vibrating characteristic of four stroke cycle. Counterweights are added for each reciprocating piston to provide engine balance while operating. Gasoline engines have curtailed compression ratio therefore shorter stoke length as a deduction have higher RPM in comparison to diesel counterpart. A crankshaft is subjected to enormous stresses, potentially equivalent of several tones of force. Failure of the crankshaft is predominantly due to violent vibrations, insufficient lubrication, excessively pressurized cylinder. This research aims to examine the stress subjected to acute points on a crankshaft. Three dimension model of 4 stroke single cylinder engine crankshaft is modeled using SolidWorks v18. End conditions were applied taking into consideration the engine mountings of the crankshaft.

Globally, the demand for energy is increasing due to both increase in population and enhancement in the lifestyle of people. Most of the energy demand at present is met from fossil fuels, which are not only exhaustible but also a threat to the environment. Various routes of sustainable energy resources are being explored to address the above-mentioned issues and fuel made from used tyre may be one of the promising options. India is one of the fastest growing economies and every year 10 million new vehicles are registered. Due to poor road conditions, nearly fourfold tyres of this number are dumped as waste. This large stock of dumped tyres are non-biodegradable and creates other problems like a breeding site for mosquitos, or source of pollution in case of accidental fire. In order to cope with the large pile-up of used tyres, pyrolysis of these tyres could be a sustainable route.

A Study on the Application of Turbo Expansion in Light Duty Gasoline and Diesel Engines: A Review

2018-04-03
2018-01-0051
Turboexpansion is a concept which is aimed at reducing the fuel consumption of pressure-charged combustion engines by providing over-cooled air to the engine prior to its induction in the combustion chamber. The performance of the engine is dependent on intake charge density which is preferred to be high at reduced charge air temperature. This becomes achievable through a cooling system known as a turbo expander which expands a high-pressure gas to produce work that is usually employed to drive a compressor. Though, initially used for the purpose of refrigeration in industries, for the past few decades various researches have proved its efficiency in internal combustion engines. In gasoline engines, it is usually employed to extend the knock limit and reduce carbon emissions. Also, an extension to the knock limit allows several improvements in parameters such as increased specific output, an increase in compression ratio and a reduction in the fuel consumption of the engine.

A Study on Homogeneous Combustion in Porous Medium Internal Combustion Engine: A Review

2017-03-28
2017-01-0788
Rapid depletion in fuel resources owing to the low efficiency of current automobiles has been a major threat to future generations for fuel availability as well as environmental health. Advanced new generation of internal combustion (IC) engines are expected to have far better emissions levels both gaseous (NOx and CO) and particulate matter, at the same time having far lower fuel consumption on a wide range of operating condition. These criteria could be improved having a homogeneous combustion process in an engine. Homogeneous mixing of fuel and air in HCCI leads to cleaner combustion and lower emissions. Since peak temperatures are significantly lower than in typical SI engines, NOx levels and soot are reduced to some extent. Because of absence of complete homogeneous combustion but quasi homogeneous combustion present in HCCI, there is still a possibility of further reducing the emissions as well as enhancing the engine performance.
