Evaporative Cooling System

IC engine spray evaporative cooling system design is discussed starting with a review of existing evaporative cooling systems that automotive applications are required to address. A component-level system design is proposed culminating in a simulation model of a PID strategy used to control transient gasside metal temperatures with varying engine load. The model combines a spray evaporation correlation model with 1D finite-difference equations to model the transient heat transfer through a 7 mm thick metal slab which represents the wall of a cylinderhead. Based on the simulation results, the particular changes required of existing engine cooling jacket designs are discussed.

Definition Of

Cooling system design has a crucial role in defining engine performance, operational limits and thermal comfort. Many further improvements with respect to the actual situation can be obtained through a more accurate control of an-board thermal needs. To this new interest the definition of new technical specifications must follow. The technical literature, however, seems not fully satisfying this need, not focusing on the influence of these technical specifications on system design, reliability and costs. In this paper the authors present a contribution in this direction, showing the capabilities of an active intelligent management of the engine cooling system. This can be obtained through different control strategies, strongly diversified for their cost-performance ratio. The potentiality of a model-based controller has been also investigated and compared with the correspondent closed-loop controller.

And Control

This paper presents temperature control of engine cooling system using a controllable magnetorheological (MR) fan clutch. An appropriate size of MR fan clutch is devised and modeled on the basis of Bingham model. Subsequently, an optimization to determine design parameters such as width of housing is undertaken by choosing the reciprocal of the controllable torque as an objective function. This has been performed using a finite element analysis. A sliding mode controller is then designed to control the angular velocity of the MR fan clutch using experimentally determined parameters. The designed controller is implemented and control performances of the MR fan clutch system are evaluated.
