Experimental Study of Premixed Laminar Combustion Characteristics of Gasoline/Air Mixtures in Constant Volume Vessel - 2024
Tong, Duy Quoc, Nguyen, Minh Tien, Nguyen, Le Chau Thanh, Pham, Minh Man, Do, Phu Nguu, Phung, Minh Tung, Bui, Van Hung, Ho, Tran Ngoc Anh
This work measures the laminar combustion characteristics of gasoline-air
mixtures at different equivalence ratios (ϕ = 0.8, 0.9, 1.0, 1.1 and 1.2) using
the pressure rise method combined with a constant volume combustion chamber. The
pressure rise...
