Emissions from two-stroke engines

'In the design of new CI engines, it is of paramount importance to reduce the pollutants and fuel consumption,' writes author Marco Nuti. In this, the first book devoted entirely to exhaust emissions from two-stroke engines, Nuti examines the technical design issues which will determine how long the two-stroke engine survives into the twenty-first century. Chapters cover: The Basics - Two-Stroke Engine Layout and Operation The Scavenging Process: Definitions and Symbols Engine Modeling and Simulation Scavenging Efficiency Evaluation Friction Losses Irregular Combustion and Spontaneous Ignition Phenomena Pollutant Formation - Unburned Hydrocarbon Emissions Carbon Monoxide Emissions Nitrogen Oxide Emissions Smog Formation Formation of Soot and Particulates in CI Engines. Active Pollutant Controls - Scavenging Port Design and Experimental Optimization Exhaust Tuning High-Pressure Direct Fuel Injection Air-Assisted Direct Fuel Injection. Passive Pollutant Controls - Thermal Afterburner Catalytic Aftertreatment Secondary Air Addition Experimental Results and Method of Prediction.
