It is the most common type of engine and can be found in virtually all motor vehicles (cars, trucks, motorcycles, buses, boats, tractors, and so on).On the basis of Fuel Used Petrol EngineA petrol engine is a type of internal combustion engine in which the fuel is ignited by the high temperature of the air in the cylinder.Types of petrol engines4-stroke petrol engines: They are the most common type of motor vehicle engines, in which air and fuel are mixed in the intake stroke and compressed in the compression stroke, then ignited by a spark plug, and the spent gases then exit in two exhaust strokes.2 -stroke petrol engine: they have fewer moving parts than 4-stroke gasoline engines and are more compact and powerful for their size. Most 2-stroke engines cannot be throttled. They are mainly used as a motorcycle or small engines.Diesel EngineDiesel engines work on the principle that fuel does not need to be ignited to burn; it only needs sufficient heat. This heat is supplied by burning a small amount of diesel fuel injected into hot air at the top of the cylinder by a fuel nozzle directly into the combustion chamber. Thus, diesel engines do not require ignition systems such as spark plugs, although they usually have glow plugs for starting purposes. The fuel-air mixture burns at constant pressure when compressed, then expanded over several strokes.Gas enginesIt is an internal combustion engine that uses gas as fuel, most commonly propane or natural gas. These engines are comparatively new and have been invented only in 20 years. Gas engines are cleaner and better than petrol and diesel engines because there is no smoke emission when they work.On the basis of Cycle of OperationThe cycle of operation is the sequence of events in which a process occurs. There are three main types of bikes:Otto Cycle EngineIt is the most commonly used internal combustion engine found in automobiles and is distributed widely worldwide.Diesel Cycle EngineDiesel engines use the diesel cycle, which operates similarly to the Otto cycle but with crucial differences. The diesel engine uses heat from compression and combustion to continue the process.Dual Cycle Engine or Semi-diesel cycle engineThis classification applies to internal combustion engines that use both Otto and Diesel cycles, such as gas turbines, etc.On the basis of Number of StrokesThe number of strokes required for the combustion to be finished is the number of strokes in an engine. This is the main characteristic of the engine type. The following are the different types of engines:Four-stroke combustion engine:It is commonly known as the Otto or diesel cycle; this is a complete combustion process. All four strokes, i.e. intake, compression, power, and exhaust, occur in each revolution of a crankshaft.Two-stroke combustion engineOnly intake and exhaust strokes occur during one revolution of a crankshaft in this engine type.Hot spot ignition engineThis type of engine has no crankshaft, cylinders, or

AbstractExperiments on the organization of the combustion of kerosene in high-enthalpy supersonic air streams is analyzed. The use of promotor additives, as well as improvements in the atomization process, vaporization, and mixing, do not always facilitate efficient combustion development. The existence of a conversion process is found to have a significant effect on the ignition parameters. The burnup intensity can be ensured by adding hydrogen, and the relative position of the fuel injectors is important in that case. The fundamental role of wave structures in determining the length of the combustion zone in the channel is noted. The integral characteristics of combustion for hydrogen and kerosene are compared.

In real combustion processes, rich fuel conditions can lead to the production of CO, aromatics, UHC, and soot, while lean conditions can release oxygen-rich substances like ketones, peroxides, and NOx [124]. Secondly, local low-temperature zones, where the combustion chamber may have regions of lower temperature, especially at the flame front edges or where fuel spray contacts the cold wall surface. Low temperatures can inhibit combustion reactions, causing some fuel molecules to exit with the exhaust before oxidizing. Thirdly, there is poor fuel atomization, where, if there are issues with the fuel nozzle or improper fuel pressure, the fuel may not atomize adequately into fine droplets, with larger droplets less likely to evaporate quickly and mix with air, increasing the likelihood of incomplete combustion. Finally, there is short residence time. Modern jet engines aim for high efficiency with compact combustion chambers, resulting in very short fuel residence times. This can prevent complete combustion of some fuel before it is expelled [125,126,127,128,129,130].UHCs are a subset of volatile organic compounds (VOCs). A significant portion of VOC emissions from aircraft engines consists of UHCs [131,132]. These compounds undergo photochemical reactions with nitrogen oxides under sunlight, producing ozone and other secondary pollutants such as peroxyacetyl nitrates (PANs), which are primary contributors to photochemical smog and significantly impact air quality [133,134]. Although most UHCs have a short atmospheric lifespan, their involvement in various chemical reactions can lead to the formation of GHGs, like methane and carbon dioxide, indirectly contributing to global warming [124,135]. Over 8 million people fly on commercial airplanes daily, with approximately 5% suffering from respiratory diseases. Therefore, it is necessary to maintain high air quality onboard to protect the health of both crew and passengers. Formaldehyde, benzene, tetrachloroethylene, trichloromethane, 1,2-dichloroethane, and naphthalene are the six primary VOCs in the current cabin environment, posing risks to crew members that exceed the acceptable levels recommended by the US EPA [136]. Xylene in the cabin is significantly associated with irritation of the eyes, nose, and throat. Aldehydes, potential oxidation products of ozone, can also irritate human senses. Common symptoms among crew members and pilots include dry eyes and fatigue [137]. These VOCs may impact perceived indoor air quality and lead to passenger complaints. [138]. In air monitoring studies at Zurich Airport, a significant presence of reactive C2–C3 olefins and isoprene was found in engine exhaust. Isoprene was not detected in refueling emissions, and the benzene to toluene ratio in exhaust (1.7) was also higher than in kerosene refueling emissions (well below 1) [139]. Exposure to UHCs and VOCs poses health risks to humans. Inhalation of UHCs can irritate the eyes, nose, and throat, cause coughing, wheezing, and other respiratory issues, and increase the risk of chronic bronchitis and emphysema [140,141]. Long-term exposure to high VOC concentrations may raise the risk of cardiovascular diseases,

Combustion: Definition, Types, Condition For Combustion

By Romain Nicolas The impact of greenhouse gases on our environment has been a growing concern over the past few decades. The rise of industrialization and the increased use of fossil fuels have led to an increase in the concentration of greenhouse gases in our atmosphere. These gases, such as carbon dioxide (CO2), methane, and nitrous oxide, trap heat in the atmosphere and contribute to global warming, which has a devastating impact on our planet.One of the most significant contributors to greenhouse gas emissions is the transport sector. According to the International Energy Agency, the transport sector accounts for around 24% of global energy-related greenhouse gas emissions. This includes emissions from cars, trucks, buses, airplanes, and ships. With the continued growth of the global population and the increasing demand for transportation, it is essential that we address the environmental impact of the transport sector if we are to mitigate the effects of climate change.This blog will describe why hydrogen (H2) combustion engines can support greenhouse gas emissions reduction and how their design is supported by Simcenter Amesim 2304.Why hydrogen combustion?There are ambitious worldwide goals to reduce CO2 emissions in the road transport sector. These goals are most usually solution-neutral; meaning that they can be reached either through electric vehicles or internal combustion engine vehicles using e-fuels or carbon-free fuels (ammonia or hydrogen).The carbon-free fuels combustion is promising in sectors where the transportation infrastructure is the easiest to adapt, and where the energy and power demands are high i.e., heavy equipment and long-haul trucks.Comparison of zero-emissions technologies for different vehicle types. Source: McKinsey&CompanyIn that context, several industry players invest some R&D efforts in the hydrogen internal combustion engine technology pathway. Critical design criteria of hydrogen internal combustion enginesThe H2 combustion engine requires significant engineering efforts to meet power, efficiency, controllability and safety requirements.Most of these engineering activities are related to the hydrogen thermodynamic properties. Indeed, the gaseous fuel has low density, high flammability and high lower heating value. It means for example that the fuel injection system is prone to H2 leakages, and that, when injected, it occupies a large part of the combustion chamber, requiring a lot of air and an efficient turbocharging system. Knocking sensitivity and NOx emissions are also significant challenges that can be solved in several ways (water injection, exhaust gas recirculation -EGR- …). Most of these challenges can be addressed in Simcenter Amesim engine solution using a high frequency modeling approach.Simcenter Amesim engine modeling solutionsA proper engine calibration is also important to avoid misusing the designed engine components. Parameters like start of injection, lambda and spark timing will have a strong impact on NOx, knock and H2 consumption, regardless of the chosen design in steady state conditions. These calibration parameters are usually defined on engine test bench, but virtual (pre)-calibration is a cost-effective solution to save test bench running hours. This virtual calibration is most of the time done using Software-In-the-Loop or Hardware-In-the-Loop methodologies and these are best supported in Simcenter Amesim by using a mean

6 Pages Posted: 27 Dec 2024 Date Written: December 20, 2024 Abstract This work presents the design of a solvent-based post-combustion CO2 capture pilot to be tested on real cement flue gases. The pilot plant, employing solvent-based CO2 absorption/stripping in packed columns, has been designed to capture and produce 3 t per day of high purity liquid CO2 from a slip stream of flue gases from a cement kiln. Process design is performed via Aspen Plus V14 simulations considering 30% w/w aqueous MEA as chemical solvent. More than 10 configurations featuring several modifications to the standard post-combustion process have been evaluated and characterized in terms of equivalent energy consumption. The process configuration featuring the integration of absorber intercooling, rich solvent split and lean vapor recompression is one of the most energy efficient and it reports a substantial reduction (18% savings) in the equivalent energy consumption compared to the conventional CO2 capture MEA process.
