An Experimental Investigation of Fuel Transport in a Port Injected Engine 952485
The transport of fuel during cold start in the intake of a port-injected engine has been investigated using a standard engine with very little modification. A fast response FID sampling from the intake manifold is used to measure the instantaneous vapor concentration during the start. At short times after the start, the engine is stopped, and the port under investigation isolated. The engine is then warmed up by passing hot water through it and at the same time is flushed with hot air, in the port and the cylinder. This evaporates the liquid fuel, and by integrating the vapor concentration multiplied by mass flow of the displaced gas, the fuel mass in the isolated port and cylinder is measured. It is shown how the mass of liquid in the port at the time at which the engine is stopped can reliably be related to the concentration measurement. By stopping the engine at different times after the start, detailed accounting of the fuel transport as a function of time since start can be made.
