ABSTRACT
Today’s world facing problem of increasing environmental pollution, growing threat of
depleting fossil fuels, and ever increasing uncertainty of fuel prices. Indiscriminate
extraction and lavish consumption of fossil fuels have led to reduction in underground
based carbon resources. A single-cylinder engine is a basic piston engine configuration
of an internal combustion engine. The primary goal of this research was to advance the
single-cylinder engine system. Single-cylinder engines are simple and compact, and will
often deliver the maximum power possible within a given envelope. Cooling is simpler
than with multiple cylinders, potentially saving further weight, especially if air cooling
can be used. Single-cylinder engines are simple and economical in construction. The
present work has resulted in giving a good insight into the combustion, performance and
emission characteristics and optimization of engine.
Keywords: Single cylinder engine; combustion engine.
INTRODUCTION
Combustion, torque, power, emissions and fuel consumption are very important
parameters for the efficiency and performance of the engines, and all of them are
directly influenced by the geometry of the combustion chamber [1-3]. Heisler says that
an effective combustion chamber has to create conditions for the air-flow mixture that
optimizes the combustion flame, making it fast and uniform, and facilitate the burned
gases expulsion [2]. The increases of the air-fuel mixture process along with the heat
transfer rate are consequences of the increase of the Center of Mobility Technology
(CTM -UFMG) turbulent flux inside the cylinder, overcoming the process of molecular
diffusion [4]. In-cylinder engine modeling is a necessary aspect of combustion research.
In particular, simulating heat release connects variable combustion behavior to fuel
properties through the 1st Law of Thermodynamics [5]. The thermodynamic modeling of
in-cylinder combustion processes helps to characterize fuel behavior. The standard in-
cylinder model uses the calculation of the engine-out rate of heat release (RHR) [6-7].
One of the primary properties dening CI engine combustion behavior is fuel viscosity
[8]. The hydrogen addition to gaseous or liquid fuels offers good environmental and
energy performances as it was well proven in the last decade [9-16]. Real-time
combustion control is one of the most heavily researched applications for in-cylinder
pressure applications [17-22].

CONCLUSIONS
Cylinder pressure data analysis is the most effective tool to analyze engine combustion
behavior because cylinder pressure history directly influences power output,
combustion characteristics and engine-out emissions [23]. Due the low heating value
and higher latent heat of evaporation of fusel oil the volumetric efficiency increased
with F20 and due the high water content of fusel oil, the in-cylinder temperature slightly
decreased [24]. Inertial force of crankshaft-connecting rod in a single-cylinder engine
has a remarkable influence on vehicle vibration and comfortability [25]. crankshaft
bearing, piston assembly, and pumping loss have a major effect on the transient
performance of the engine [26]. The fuel to air mass ratios computed on the basis of
composition measurements agree well with the inlet measured values [27].

Article
In order to reduce the dependency on fossil oil energy resources, the using of several energy resources in compression-ignition engine has been the target of attention of researchers. The major renewable alternative combustible species are methanol, biogas, ethanol, biodiesel, and hydrogen. Fusel oil is a by-product of bioethanol production during the fermentation process present one of the new alternative fuels for compression-ignition engine. The aim of this work is to experimentally investigate the effect of fusel oil –diesel blending on performance and emission in single cylinder compression ignition engines. The test achieved under 25 % engine load at five-engine speed 1200 to 2400 rpm with intervals of 300 rpm. The experimental results revealed that the engine indicted power and torque slightly decrease for F 2 0 compared with pure diesel, and the increment was happened in fuel consumption. Although diesel fuel yields, the highest volumetric efficiency and exhaust temperature. Moreover, the results showed CO 2 and CO were increased while the NOx emissions decrease with the use F 2 0. All the negative effects that happened in power and torque was because of the water content, low heating value, low cetane number for fusel oil.

Inertial force of crankshaft-connecting rod in a single-cylinder engine has a remarkable influence on vehicle vibration and comfortability. The relationship between theoretical inertial force graph in ellipse distribution and experimental inertia force graph in 8-pattern distribution was investigated. The inertial force experimental method through shifting cylinder in a testing bed by angle was proposed, and the main representing parameters for inertia force were obtained. Based on initial force model for single cylinder engine, the relationships among the angle of rotating mass of the crankshaft-connecting rod, the ratio of rotating mass to reciprocating mass and the maximal inertial force, the unbalance ratio was investigated. Moreover, the selecting criteria for initial force were discussed, and the experimental calibrating approach was given.

In-cylinder engine modeling is a necessary aspect of combustion research. Heat release modeling in particular serves as a means to connect variable combustion behavior to fuel properties through an analysis based on the First Law of Thermodynamics. One extension of such models is to evaluate the changes in in-cylinder behavior using the Second Law of Thermodynamics, in order to identify the peak period of availability for work extraction, and is thus a useful tool to augment research into alternative fuel usage and optimization. Second Law models are also necessary in identifying internal irreversibilities that are separate from heat transfer and exhaust gas losses. This study utilizes a multi-zone First and Second Law Heat Release model to characterize the changes in combustion behavior of a number of neat fuels used in a single-cylinder diesel engine, namely standard diesel, biodiesels derived from jatropha and tallow feedstocks, Jet A aviation fuel, aviation fuel derived from renewable sources, and a synthetic fuel derived from waste plastics. In all cases, fuel injection timing was adjusted to align the peak pressure timing of each fuel with that of diesel. Overall, variations in fuel properties were found to bring about considerable changes in engine operation from the standpoint of the Second Law Model. Most prominently, fuel density, energy content, fuel molecule structure, and viscosity serve as the primary fuel characteristics that drive combustion timing, duration, and intensity. In particular, it is shown that high viscosities (characteristic of biodiesels and some synthetics) lead to delayed and prolonged combustion, which serves to add availability to the working fluid later in the expansion stroke, making it more difficult to extract that availability as work.
Article
In meeting the stringent emission norms with internal engine measures, the design of the piston bowl and the nozzle configuration perform a defining role. Through 3D CFD simulations, this article shall parametrically investigate the influence of piston bowl geometry and nozzle characteristics on the performance of the combustion system. After validation of the 3D simulation model with experimental results, a Design of Experiment (DoE) method shall be applied to analyze a matrix of piston bowls with parametric variations in geometry. Further, the influence of the nozzle cone angle, hydraulic flow rate, number of holes and their combination shall be determined using systematic parameter variations with selected piston bowl designs. The performance of the various hardware configurations would be evaluated based on the exhaust emissions and fuel consumption values. The combustion system under consideration is the Advanced Heavy Duty Combustion System (AHDCS) developed by FEV, which employs a narrow cone angle and a deeper piston bowl. Very high rail pressures and highly cooled Exhaust Gas Recirculation (EGR) strategy shall be used to exploit the full potential of the combustion system. An understanding of the phenomenological behavior of the spray-bowl interaction based on this parametric analysis would lay the groundwork for further optimization of the combustion system.
Conference Paper
The paper discusses a high pressure injection equipment (HPIE), which is an electronically controlled, hydraulic pressure-intensified system that can produce 250MPa, that has been developed. This equipment has been evaluated with shadow photographs for analyzing non-evaporating fuel spray characteristics. It was found that the fuel injected at high pressure forms a finer and more homogeneous spray. When the HPIE was fitted to a naturally aspirated 2 liter single-cylinder diesel engine and tested, it was found that black smoke and particulate emissions decreased, under suitable injection timing for low NOx emission. The emission test data at 220MPa of injection pressure shows that more than 80% reduction of particulate emission has been realized at the same NOx level. These results indicate that the high pressure fuel injection is an effective means for reducing NOx, smoke and particulate emissions. For the covering abstract see IRRD 865952.

Diesel spray structure is studied using optical diagnostics. A single-hole common rail diesel injector is used to enable high injection pressures up to 150 MPa. The spray is observed in a high-pressure, high-temperature cell that reproduces the conditions existing in a combustion chamber of a diesel engine during injection. The liquidphase of the spray is studied using laser-induced exciplex fluorescence (LIEF). The vapor phase is studied using an innovative measurement technique for which a high-boiling point tracer is added to the fuel. The vaporized part of the spray is visualized by tracer droplet light scattering of a laser sheet. The technique is made quantitative with an appropriate calibration method. These two diagnostic methods are then used to build a database of liquid phase visualizations and of quantitative two-dimensional distributions of fuel vapor concentration, with varying injection parameters. A detailed analysis of the structure of sprays is done. It is found that the liquid spray exhibits an area of high optical density at the outlet of the nozzle, with an abrupt transition to a fully atomized spray within a few nozzle orifice diameters. The structure of the fully atomized spray is comparable to a bundle-like structure, and is found to be the consequence of transient phenomena occurring in the nozzle. The structure of the vapor plume is similar, showing evenly distributed areas with steep gradients at the edges. This result is deducted from single-shot measurements and is found to contrast significantly with the more progressive structure of multipulse averages. This structure of the fuel vapor is expected to be responsible for the location of autoignition that occurs at multiple points nearly simultaneously. Finally, the effect of injection pressure is discussed. An increase of injection pressure is found to enhance the atomization at the nozzle outlet, resulting in a more distributed vapor phase, hence resulting in better mixing.

The effect of fuel physical properties on the ignition and combustion characteristics of diesel fuels was investigated in a heavy-duty 2.52 L single-cylinder engine. Two binary component fuels, one comprised of farnesane (FAR) and 2,2,4,4,6,8,8-heptamethylnonane (HMN), and another comprised of primary reference fuels (PRF) for the octane rating scale (i.e. n-heptane and 2,2,4-trimethylpentane), were blended to match the cetane number (CN) of a 45 CN diesel fuel. The binary mixtures were used neat, and blended at 25, 50, and 75% by volume with the baseline diesel. Ignition delay (ID) for each blend was measured under identical operating conditions. A single injection was used, with injection timing varied from −12.5 to 2.5 CAD. Injection pressures of 50, 100, and 150 MPa were tested. Observed IDs were consistent with previous work done under similar conditions with diesel fuels. The shortest IDs were seen at injection timings of −7.5 CAD. The largest difference in ID between all fuels of 75 ± 18 μs was observed at the earliest injection timing with an injection pressure of 50 MPa. The average difference in ignition delay between individual blends was 35 ± 18 μs. None of the blends tested exhibited significant differences in ignition delay compared to the baseline diesel. The results indicate that for the density and temperature range tested, fuel physical properties have limited influence on the ignition process in a heavy-duty diesel engine. Instead, chemical ignition characteristics, i.e., CN, control the ignition delay.
Data
Fuel spray and atomization characteristics play an important role in the performance of internal combustion engines. As the reserves of petroleum fuel are expected to be depleted within a few decades, finding alternative fuels that are economically viable and sustainable to replace the petroleum fuel has attracted much research attention. In this work, the spray and atomization characteristics were investigated for commercial No. 2 diesel fuel, biodiesel (FAME) derived from waste cooking oil (B100), 20% biodiesel blended diesel fuel (B20), renewable diesel fuel produced in house, and civil aircraft jet fuel (Jet-A). Droplet diameters and particle size distributions were measured by a laser diffraction particle analyzing system and the spray tip penetrations and cone angles were acquired using a high speed imaging technique. All experiments were conducted by employing a common-rail high-pressure fuel injection system with a single-hole nozzle under room temperature and pressure. The experimental results showed that biodiesel and jet fuel had different features compared with diesel. Longer spray tip penetration and larger droplet diameters were observed for B100. The smaller droplet size of the Jet-A were believed to be caused by its relatively lower viscosity and surface tension. B20 showed similar characteristics to diesel but with slightly larger droplet sizes and shorter tip penetration. Renewable diesel fuel showed closer droplet size and spray penetration to Jet-A with both smaller than diesel. As a result, optimizing the trade-off between spray volume and droplet size for different fuels remains a great challenge. However, high-pressure injection helps to optimize the trade-off of spray volume and droplet sizes. Furthermore, it was observed that the smallest droplets were within a region near the injector nozzle tip and grew larger along the axial and radial direction. The variation of droplet diameters became smaller with increasing injection pressure.

This study was carried out to characterize the engine-exhaust particulate emissions from a typical multipoint port fuel injection gasoline engine used in transportation sector. Though gasoline engine showed no visible tail pipe emissions yet its particle concentrations were comparable to mineral diesel, particularly at high engine loads. Average sizes of particles emitted in gasoline exhaust are found to be way smaller than particles emitted in diesel exhaust under similar operating conditions. The peak particle concentrations for mineral diesel never go below 40nm size however for gasoline engine, it was as low as 20nm for most engine operating conditions. Within a very limited operating range, gasoline engine performance was superior to its diesel counterparts in terms of particulate size and number distribution however it deteriorates very quickly as soon as the fuel–air mixture becomes closer to stoichiometric ratio, typically under high engine load and speed conditions.
