Feasibility of Water Injection for Particulate Removal in Large Turbocharged Diesel Engines

摘要

Gaseous and particulate exhaust emissions are characterized for a 1,200-bhp, two-stroke cycle diesel; a 1,000-bhp, four-stroke cycle precombustion chamber diesel; and a 900-bhp, four-stroke cycle, direct injection diesel using steady-state modal testing and a versatile exhaust dilution-collection system. In addition, a 150-bhp, four-stroke cycle, precombustion chamber, tuborcharged diesel was characterized for use in experimental water injection evaluations. Water injection downstream of the turbocharger compressor and upstream of the turbocharger exhaust turbine are evaluated for their particulate removal effectiveness on a small turbocharged diesel engine.
