Intake manifold water injection (IMWI) is an effective way to control combustion temperature and NOx emission for diesel engines. The various effects of IMWI on emissions reflect the dilution effect, thermal effect chemical effect. However, researchers have paid little attention investigate three effects. In this study, dilution, characteristics a four-stroke, direct as well turbocharged engine are investigated by CFD simulation. results indicate that reduces in-cylinder mean pressure temperature, ignition delay becomes longer. leads remarkable decrease Soot emissions. Comparing plays dominant role.
