In-cylinder flow in two optical engines
High-speed imaging of spray of a multi-hole gasoline injector was conducted within an optical engine at a repetition rate of 16 kHz.
High-speed imaging of the spray of a multi-hole gasoline injector was conducted within an optical engine at a repetition rate of 16 kHz. Bottom illumination by the ILA LPS II pulsed LED through the piston is used to capture the liquid content of the spray using Mie scattering. With this approach, the propagation and mixing of a directly-injected fuel can be studied non-intrusively. The experimental data is used to benchmark mathematical models describing the disintegration of sprays within engines.
