Book excerpt: Optimizing airflow performance during intake valve process is the main purpose for this project. Research had using two previous works as guidance and starting point to setting and achieving targeted limit of optimized airflow, 0.0201075 m3/s. modifications on inlet valve, inlet port of intake system had been done, and original cylinder head Ex5 geometry had been used before turning into 3D modeling as to achieve objective. Analysis was done in CFD simulation and experimental using SuperFlowbench machine. This analysis also reported differentiation that occurs during both analyses around 0.045 % in average where experimental result cannot achieve targeted limit due to some realistic condition. Fabrication of intake valve and intake port also were made to do analysis on experimental based on the modify design. This being done after simulation analysis, modeling design was using to be fabricated and analyze the model on flow bench machine to verify simulating result. This analysis could be used to increase efficiency of volumetric flow rate and maximizing usage of air fuel in combustion process, which reduce emission to environment. Even though air flow have been optimized on its intake valve and port, but still intake system could be improve by considering other parts of Ex5 engine such as intake manifold.

Available in PDF, EPUB and Kindle. Book excerpt: This project is focused to investigate the test rate characteristics through the intake and exhaust ports of four-stroke single cylinder engine (Modenas Kriss 110cc) by using flowbench machine. This investigation is to measure the volumetric flow rate into intake and exhaust valve ports at various valve lift by using flowbench machine. The flow characteristic through the intake and exhaust valves at various engine vacuum conditions must also be investigate. This investigation is done by disassembling the engine in order to obtain the cylinder head. That cylinder head engine is mated to an adapter as replacement for the cylinder block engine. After that, the adapter and cylinder head will be mounted on flow bench machine. The test bench is prepared to vary the intake and exhaust valves lift to be mounted on the flow bench and then the flow test is conducted at various test pressures. A variety of valve opening was measured by using dial gauge and various test pressure is measured at Flowbench setting. The flow bench can read correction test flow and flow velocity. Flow will increase directly proportional to the valve lift. At the highest test pressure, flow is the greatest.

Download or read book Intake Valve Modelling of a Four Stroke Internal Combustion Engine at Idling Speed written by Md. Syed Ali Molla and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Intake valve of a four stroke internal combustion (Ie) engine has been modelled to investigate the effects of intake valve diameter and intake valve angle on volumetric'efficiency and air flow properties of intake air in a four stroke internal combustion engine. It is found that the increase of intake valve diameter increases the peak vertical velocity component but decreases the peak horizontal velocity component of intake air in suction stroke. It is also found that the increase of intake valve diameter decreases the peak turbulence kinetic energy and dissipation rate of intake air to a small extent. The effects of intake valve diameters on the cylinder pressure in suction stroke become significant from the suction valve full opening timing to the middle of suction stroke but its effects become insignificant (diminished) at the time of suction valve closing. The effects of intake valve diameters on the intake air temperature are also found very small at the end suction stroke. Thus, the small variations between the computed pressure and temperature inside the cylinder at end of suction stroke for different intake valve diameters have little influence on volurr-Jletric efficiency. While investigating the effect of intake valve angle on the airflow properties, it is found that the larger intake valve angle decreases the vertical velocity component as well as the horizontal velocity component. The increase of intake valve angle decreases the turbulence kinetic energy and dissipation rate moderately. The effects of intake valve angles on the cylinder pressure and temperature in suction stroke are very small from intake valve opening timing until the end of suction stroke. Thus, the present investigation shows that variation in intake valve diameter has very small effect on volumetric efficiency and the necessity of increasing intake valve number is not so important. Moreover, intake valve angle can be increased in order to increase valve thickness and valve life.

Download or read book Assessment of Fuel Economy Technologies for Light Duty Vehicles written by National Research Council and published by National Academies Press. This book was released on 2011-06-03 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various combinations of commercially available technologies could greatly reduce fuel consumption in passenger cars, sport-utility vehicles, minivans, and other light-duty vehicles without compromising vehicle performance or safety. Assessment of Technologies for Improving Light Duty Vehicle Fuel Economy estimates the potential fuel savings and costs to consumers of available technology combinations for three types of engines: spark-ignition gasoline, compression-ignition diesel, and hybrid. According to its estimates, adopting the full combination of improved technologies in medium and large cars and pickup trucks with spark-ignition engines could reduce fuel consumption by 29 percent at an additional cost of $2,200 to the consumer. Replacing spark-ignition engines with diesel engines and components would yield fuel savings of about 37 percent at an added cost of approximately $5,900 per vehicle, and replacing spark-ignition engines with hybrid engines and components would reduce fuel consumption by 43 percent at an increase of $6,000 per vehicle. The book focuses on fuel consumption-the amount of fuel consumed in a given driving distance-because energy savings are directly related to the amount of fuel used. In contrast, fuel economy measures how far a vehicle will travel with a gallon of fuel. Because fuel consumption data indicate money saved on fuel purchases and reductions in carbon dioxide emissions, the book finds that vehicle stickers should provide consumers with fuel consumption data in addition to fuel economy information.

D. Eppes and published by . This book was released on 1947 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of tests have been made with a single-cylinder engine in order to determine the effect on volumetric efficiency and on engine performance of changing the ratio of exhaust-valve flow capacity to inlet-valve flow capcity when operating with exhaust pressure equal to inlet pressure. It was found that, within the range of speeds used, the engine gave best performance with values of the ratio of exhaust-valve flow capacity to inlet-valve flow capacity approximately equal to unity. This value corresponds to inlet and exhaust valves of approximately equal diameter and lift. It was also found that conventional valve timing gave better performance than any of the other timing arrangements tried, except at speeds higher than those used, where it appeared from the trend of the curves that delaying the inlet-valve closing would increase volumetric efficiency and mean effective pressures.

Download or read book A Methodology for Turbocharging Single Cylinder Four Stroke Internal Combustion Engines written by Michael Rafael Buchman and published by . This book was released on 2015 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a method for turbocharging single cylinder four stroke internal combustion engines, a model used to evaluate it, an experimental setup used to test it, and the findings of this experiment. A turbocharged engine has better fuel economy, cost efficiency, and power density than an equivalently sized, naturally aspirated engine. Most multi-cylinder diesel engines are turbocharged for this reason. However, due to the timing mismatch between the exhaust stroke, when the turbocharger is powered, and the intake stroke, when the engine intakes air, turbocharging is not used in commercial single cylinder engines. Single cylinder engines are ubiquitous in developing world off grid power applications such as tractors, generators, and water pumps due to their low cost. Turbocharging these engines could give users a lower cost and more fuel efficient engine. The proposed solution is to add an air capacitor, in the form of a large volume intake manifold, in between the turbocharger compressor and the engine intake to smooth out the flow.
