Increasing the Power and Efficiency of Engines

HIGH-PRESSURE TURBOCHARGING: INCREASING INTERNAL COMBUSTION ENGINE EFFICIENCY AND POWER WHILE REDUCING EMISSIONS Gheorghiu, Victor* Hamburg University of Applied Sciences Berliner Tor 21, 20099 Hamburg, Germany Keywords: Atkinson Cycle, Ultra-Downsizing, High Pressure Turbocharging, CO2 and NOx Reduction. ABSTRACT The Downsizing of internal combustion engines (ICE) is already recognized as a very suitable method for the concurrent enhancement of the indicated fuel conversion efficiency (IFCE) and lowering

in-cylinder pressure during 4-engine speed is shown in Figure1a, b, c, & d. From the in-cylinder pressure trace, it can be seen that the addition of BA will retard ignition timing. The timing of peak combustion pressure is slightly retarded consequences, of BA adding. The pressure rise rate in the figure 1a and b shows that BA-containing fuels have a higher-pressure rise rate at speed1400 and 1800 to 10% BA. A relative higher-pressure rise will assist to improve thermal efficiency. Figure1c&d shows that

Abstract The efficiency of an automobile engine is low as all the energy produced by the engine by burning the fuel is not used completely. A large portion of the energy is lost in friction, cooling and exhaust heat. This lost energy is almost around 50% [1]. Heat is a major reason for the loss in efficiency. All of the automotive industry is working towards reducing the losses by making more efficient technologies which can improve the vehicle efficiency. In this project we focus on the various

The advancements in mechanical engineering over the past few years have improved greatly especially in the automobile industry where the engines of automobiles are quieter, faster, and more fuel efficient. As technology advances in society, so do the fields of study that utilize these updated forms of technology. Mechanical engineers have improved automobile engines based on these technologic advances. Currently, the areas where engineers are focused include enhancing the transmissions, improving

ota needs to solve the problem in their hybrid Cars in order to make it popular. By: Subindas Kadukaparambil Subramanian Student ID:C0692533 Figure 1: (Toyota, 2015)   Introduction Hybrid car is the one that utilize more than one means to power the vehicle. Toyota started manufacturing hybrid cars decades before, still more people are not interested to buy it. Implementing new technology require hard work and, importantly continuous monitoring and rectifying the draw backs. Toyota need to solve

Cycle with the aid of property diagrams and describe the thermodynamics process of a Diesel Cycle in the form of written report. Diesel Cycle: Diesel Cycle is a compression ignition engine rather than the spark ignition which is invented by Rudolph Diesel in 1897. It is used widely in diesel engines. Diesel engine is as same as Otto cycle but in diesel cycle there is a constant pressure process rather than constant volume process in Otto cycle. Diesel cycle can be explained and understood with the

Turbine Engines, Brayton Cycle and Thermodynamics I 'm writing this research paper for my Thermodynamics class with Professor Roh. I have a big interest in turbine gas engines and how they operate. My future goal within mechanical engineering is to learn how to maintain and design turbine gas engines. How do Turbine Gas Engines operate? I read this article at Wartsila website which enlightened me that Gas turbines are comprised of three primary sections mounted on the same shaft: the compressor

Automobiles works on the fuel in which chemical energy is stored. This chemical energy is converted in mechanical energy by combustion of fuel in engine of cars. But most of energy is wasted in the exhaust of the automobile hence the efficiency of the vehicle also decreases. By using this major amount of exhaust energy we can improve the efficiency of vehicle. Experimental study states that 35% of total heat is wasted in exhaust. Therefore an attempt is made to use this waste for production of

The Stirling engine, noted for its high efficiency, converts heat energy to mechanical work. A typical Stirling cycle consists of four phases - compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle. The engines can run on heat from solar, geothermal, biological, nuclear sources or waste heat from industrial processes, can be built to run quietly and don’t produce any emissions. In contrast to other solutions used in solar thermal technology

Power Split Architecture Power-split hybrid powertrain are ones which consists of power-split device (PSD), an Internal Combustion Engine (ICE), two Electric Machines (EMs), ESS and VCC. Power-split architectures is a match between series and parallel hybrid to obtain advantages of both series and parallel hybrid architectures. The produced engine torque is split into two parts, which are further delivered to the output shaft by the means of an efficient mechanical path and another less efficient
