The soot formation region is mapped on ϕ-T diagram using the results obtained in the experiments and the published data. NO formation region is also determined by the Zeldovich equations and is plotted on the same diagram. The time histories of ϕ and T of the flame in a DI diesel engine which was obtained by a gas sampling study, are plotted on the ϕ-T diagram to form a trajectory. Discussion of the trajectory in relation to both soot and NO formation region gives suggestion of a possibility of high temperature - rich mixture combustion to reduce particulate formation in diesel engines.</div>","claims":[{"public_id":"cl_6a45ef9eb02e6cd955412e526a875700","status":"active","text":"A flame trajectory derived from gas-sampling time histories of ϕ and T in a DI diesel engine indicates that high-temperature, rich-mixture combustion may reduce particulate formation.","confidence":0.93,"contributors":[{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["extraction"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/claims/cl_6a45ef9eb02e6cd955412e526a875700"},{"public_id":"cl_85f5c1ccc5afa493b65afae7c404bb97","status":"active","text":"Soot formation at high pressures up to 5 MPa depends on temperature and equivalence ratio, and the soot formation region can be mapped on a ϕ-T diagram from experiments and published data.","confidence":0.97,"contributors":[{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["extraction"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/claims/cl_85f5c1ccc5afa493b65afae7c404bb97"},{"public_id":"cl_06d55285565fe22dd68934103ae33f4e","status":"active","text":"The NO formation region can be determined from the Zeldovich equations and plotted on the same ϕ-T diagram.","confidence":0.92,"contributors":[{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["extraction"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/claims/cl_06d55285565fe22dd68934103ae33f4e"}],"concepts":[{"public_id":"co_1df9dddd8a89c5cdc45c9dcbe53bb893","status":"active","name":"ϕ-T diagram","description":"A plot of equivalence ratio against temperature used to display combustion regions and trajectories.","types":["diagram"],"aliases":["phi-T diagram"],"contributors":[{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["extraction"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/concepts/co_1df9dddd8a89c5cdc45c9dcbe53bb893"},{"public_id":"co_219dcb18ebb2869e92219b33fa159a72","status":"active","name":"Zeldovich equations","description":"A set of chemical kinetic equations used to estimate NO formation.","types":["theoretical model"],"aliases":[],"contributors":[{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["extraction"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/concepts/co_219dcb18ebb2869e92219b33fa159a72"},{"public_id":"co_2510213cff3fd5da48864f1c47295ee3","status":"active","name":"equivalence ratio","description":"The fuel-to-oxidizer ratio used to characterize mixture richness or leanness.","types":["combustion parameter"],"aliases":["ϕ"],"contributors":[{"id":1,"public_id":"12632b8b5f","public_label":"Anonymous (12632b8b5f)","roles":["extraction"],"url":"https://sah.borca.ai/u/12632b8b5f"}],"url":"https://sah.borca.ai/concepts/co_2510213cff3fd5da48864f1c47295ee3"},{"public_id":"co_2de5cdf7e102924cfdd5aa9d76153fce","status":"active","name":"high temperature -
