Method of A/F Control During SI Engine Cold Start, Part 2 982521

This work presents an approach for developing a control algorithm for fuel delivery at cold start based on C.F. Aquino's fuel film dynamic model [1].
The control algorithm presented takes into account the fuel delivery both in the fuel film form and in the form of droplets and vapor, that allows setting the limits on the fuel supply calculation in order to achieve good startability (without spark plug wetting) and low CO and HC emission.
An algorithm was developed as a computer program and tested in calculation experiments. Although the empirical parameters of mathematical fuel delivery model were determined on a carburetor engine, this control algorithm is also applicable to engines with fuel injection due to similarity of the physical nature of mixture preparation.
