چکیده
This paper presents a feedback deign approach to the cold-start speed control for spark ignition engines. First, in order to ensure successful combustion in the transient mode, a fuel injection controller is given based on the air charge estimation with inverse dynamics of fuel path, which is a dual sampling rate system, i.e. the estimation for the air charge is performed TDC-based, and the fuel injection command is delivered cycle-based, respectively. Then, a speed control scheme is proposed that provides a coordination between the spark advance and the throttle operation. A supervisor is exploited to management the multi-control laws. Finally, simulation results will be demonstrated which are carried out on a full scale 6-cylinder engine system simulator provided by the SICE benchmark problem.

In spark ignition (SI) engines, the accurate control of air fuel ratio (AFR) in the stoichiometric value is required to reduce emission and fuel consumption. The wide operating range, the inherent nonlinearities and the modeling uncertainties of the engine system are the main difficulties arising in the design of AFR controller. In this paper, an optimization-based nonlinear control law is a...

This paper investigates optimal strategies for minimising the conflicting objectives of fuel consumption and warm up duration following an engine cold start. Using a reduced order model, parametric solutions for the optimal air-fuel ratio, valve timing, cam timing and idle speed setpoint are sought in the presence of input constraints. The results are then validated using a dynamic programming ...
