This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A combined experimental and theoretical investigation of the nature of the combustion processes in a dual chamber stratified charge spark ignition engine is described. This work concentrated on understanding the mixing process in the main chamber gases. A specially constructed single cylinder engine was used to both conduct experiments to study mixing effects and to obtain experimental data for the validation of the computer model which was constructed in the theoretical portion of the study. The test procedures are described. Studies were conducted on the effect of fuel injection timing on performance and emissions using the combination of orifice size and prechamber to main chamber flow rate ratio which gave the best overall compromise between emissions and performance. In general, fuel injection gave slightly higher oxides of nitrogen, but considerably lower hydrocarbon and carbon monoxide emissions than the carbureted form of the engine. Experiments with engine intake port redesign to promote swirl mixing indicated a substantial increase in the power output from the engine and, that an equivalent power levels, the nitric oxide emissions are approximately 30% lower with swirl in the main chamber than without swirl. The development of a computer simulation of the combustion process showed that a one-dimensional combustion model can be used to accurately predict trends in engine operation conditions and nitric oxide emissions even though the actual flame in the engine is not completely one-dimensional, and that a simple model for mixing of the main chamber and prechamber intake gases at the start of compression proved adequate to explain the effects of swirl, ignition timing, overall fuel air ratio, volumetric efficiency, and variations in prechamber air fuel ratio and fuel rate percentage on engine power and nitric oxide emissions.

This book was released on 2022-06-24 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuel injection systems and performance is fundamental to combustion engine performance in terms of power, noise, efficiency, and exhaust emissions. There is a move toward electric vehicles (EVs) to reduce carbon emissions, but this is unlikely to be a rapid transition, in part due to EV batteries: their size, cost, longevity, and charging capabilities as well as the scarcity of materials to produce them. Until these isssues are resolved, refining the spark-ignited engine is necessary address both sustainability and demand for affordable and reliable mobility. Even under policies oriented to smart sustainable mobility, spark-ignited engines remain strategic, because they can be applied to hybridized EVs or can be fueled with gasoline blended with bioethanol or bio-butanol to drastically reduce particulate matter emissions of direct injection engines in addition to lower CO2 emissions. In this book, Alessandro Ferrari and Pietro Pizzo provide a full review of spark-ignited engine fuel injection systems. The most popular typologies of fuel injection systems are considered, with special focus on state-of-the-art solutions. Dedicated sections on the methods for air mass evaluation, fuel delivery low-pressure modules, and the specific subsystems for idle, cold start, and warm-up control are also included. The authors pay special attention to mixture formation strategies, as they are a fundamental theme for SI engines. An exhaustive overview of fuel injection technologies is provided, and mixture formation strategies for spark ignited combustion engines are considered. Fuel Injection Systems illustrates the performance of these systems and will also serve as a reference for engineers who are active in the aftermarket, offering detailed information on fuel injection system solutions that are mounted in older vehicles.

Book excerpt: Faced with the current and future more and more drastic standards for pollutant emissions, the car manufacturers are permanently trying to improve the efficiency of spark ignition engines. One of the most effective applicable solutions for reducing the quantity of pollutant emissions (HC, CO, NOx) from the exhaust gases and also to reduce the fuel consumption is to operate with very lean mixture (equivalent ratio lower than 0.6). However, this operation concept is limited by the actual ignition systems that cannot assure an air/fuel mixture ignition in good conditions, in order to assure a complete, fast and repeatable combustion. The subject of this thesis consists into developing of a new ignition system based on a double spark plug, which can produce two quasi-simultaneous spark discharges with cumulated length few times higher than the sparks produced by a conventional spark plug. For ignition system validation, three different types of analysis have been considered: the analysis of the discharges electrical parameters, the plasma diagnosis using optical emission spectroscopy methods and the tests of the ignition system on two internal combustion engines with the exhaust gases analysis and engine performances determination. The tests revealed that the utilization of the double spark ignition system can assure a better stability in engine operation (especially in difficult ignition conditions such using very lean mixtures), increased engine performances for the same amount of consumed fuel and it can provide a diminution of the unburned hydrocarbons and carbon monoxide quantities from the exhaust gases, but with an increased quantity of nitrogen oxides, compared with a conventional ignition system.
