Internal Combustion Engine Fundamentals Heywood Solution

the growing need for reliable solutions to tackle the looming crisis of carbon emissions from internal combustion engines for their export is one of the main drivers for the development of the next generation of diesel engines. however, there are also strong arguments for the use of internal combustion engines in transport applications that require high torque levels, short response times, and prolonged operation at low speeds. based on the analysis of these engines, in this chapter, the implementation of a new cooling concept for diesel engines is proposed, as well as the development of a new engine architecture that, starting from two conventional engine blocks and two conventional cylinder heads, can provide the same structural envelope of a typical diesel engine, while adopting the new cooling concept. the proposed design has been validated using a real-size prototype, and the outcomes of this validation are also presented. the new engine concept is compared with the design for the future internal combustion engine of zf friedrichshafen, which is currently being designed for a new series of buses and has been validated in real-size prototype tests.

it is well known that the use of diesel engines in urban areas is not exempt from emission problems, in particular those related to the generation of diesel particulate matter (dpm), due to incomplete combustion. a study on the use of diesel engines in urban areas with specific features is presented here. the analysis is based on a comprehensive literature review. finally, some of the most interesting results are presented. the proposed methodology is based on a database that includes papers that were published in peer-reviewed journals.

the goal of the project is to study the behaviour of gas engines under variable conditions and to determine the most optimal conditions for a given set of parameters. the project consists of two parts: theoretical and experimental. the experimental part will be done using a test bench: a gas engine with the working principle of a four-stroke cycle (combustion, expansion, exhaust and compression). a series of tests will be performed at a fixed speed in order to simulate the engine behaviour in normal operation. the theoretical part will be done by using analytical and numerical methods: the calculations will be performed with the help of a finite element software which allows the calculation of thermodynamic and dynamic characteristics of gas engines under a variety of conditions.
the gas engine is the most widely used means of power in industry today. the use of gas engines is a key component of the energy transition. the project aims to characterize the performance of the gas engine by studying the power and efficiency, and how the power output and engine efficiency vary with the mixture composition and the working pressure. a gas engine is an internal combustion engine, in which the gaseous fuel is mixed with air and injected into the combustion chamber. once ignited, the mixture undergoes a rapid combustion process that results in the generation of heat and mechanical energy. the high-pressure phase of the combustion process (expansion and exhaust) is the most important phase and it is possible to measure the flow of the exhaust gas. the gas engine is used to produce mechanical energy by means of a reciprocating piston that compresses the air/fuel mixture and moves backwards and forwards in the engine cylinder. the method applied to the study of the gas engine consists of a series of experiments and calculations. in the experiments, the gas engine is driven by a load, while the thermodynamic variables are measured. the data obtained from the experiments are used in the calculations, which provide the theoretical values of the engine’s performance.
