Active tire pressure management, through an automatic, electro-pneumatic, central tire inflation system, is here proposed as a means of improving fuel consumption in passenger vehicles, as well as safety and drivability. A brief description of the active tire pressure control system, which has been set up at the Politecnico di Torino, is provided as a reference. Different strategies, aimed at reducing rolling resistance, through inflation pressure management, under specific vehicle working conditions, are then illustrated. The fuel benefits that can be achieved by adopting these strategies in passenger vehicles are studied by means of computer simulations using a proprietary software for vehicle performance and fuel consumption estimation. Coast-down coefficients, evaluated experimentally during deceleration tests on a closed track, are generally available at the reference tire pressure prescribed by the original equipment manufacturer of the vehicle. These fixed coefficients can then be used to describe the vehicle in simulation environments. LaClair’s relation, which illustrates the influence of tire inflation pressure on rolling resistance, has therefore been used to recalculate the coast-down coefficients as functions of the tire pressure. This has allowed fuel consumption simulations to be performed on the reference B-segment passenger car under different working conditions. In particular, the following pressure management strategies have been studied: adaptation of the inflation pressure to the vertical load, variation of the inflation pressure during tire warm-up, and adjustment of the inflation pressure, according to the average speed (urban/highway driving). The performed simulations have demonstrated that if the standard tire pressure is maintained, fuel consumption could be reduced by up to 2% in real-world driving; further advantages could be obtained by varying the target pressure as a function of the current working conditions of the vehicle.

Water utilities particularly in the developing countries are still grappling with challenges of high water losses due to leakage. District Meter Areas, pressure management and network hydraulic modeling have proven to be powerful engineering tools for reducing leakage in many developed countries notably in the UK. Despite their apparent success, these tools have not had wide application in the developing countries partly due to inadequate information on cost-benefit analyses to support management decision making in implementation of pressure management policies. To address this constraint, this paper develops a decision support tool for predicting the associated benefits to make a sound financial case for investment in pressure management strategies. The predicted benefits by the tool are compared with those derived using network hydraulic modeling to give users confidence in the tool results. The predicted benefits are illustrated on a real-developing world case study in Kampala city, Uganda. Predictions by the tool and the network hydraulic model indicate that reducing average pressure in the DMA by 7.5 m could result into annual net benefits of Euro 56,190 and Euro 66,910 respectively without compromising the customer level of service. The results obtained indicate that the predicted net financial benefits compare fairly well.
