Various aspects affecting the steam economy of a raw sugar mill are discussed. Process and prime mover steam requirements are evaluated for a new 600 ton canelhour factory currently under construction at Felixton, and options for achieving a level of steam economy where fibre can be supplied to a downstream paper mill with the appropriate fuel economy are evaluated. The necessity to allow for f...

In this work, a short preview of traffic provided by on-board sensors is used to minimize fuel consumption in a parallel hybrid vehicle capable of controlling both the vehicle velocity and the torque-split ratio. A two-stage version of Pontryagin’s minimum principle was used, but some of the standard simplifying assumptions in reduced-order modelling of hybrid vehicles were avoided to ensure th...

Plug-in Hybrid Electric Vehicles (PHEVs) offer a great opportunity to significantly reduce petroleum consumption. The fuel economy of PHEV is highly dependent on All-Electric-Range (AER) and control strategy. Previous studies have shown that in addition to parameters influencing Hybrid Electric Vehicles (HEVs), control strategies of PHEVs are also influenced by the trip distance. This additiona...

This paper proposes a virtual driving system for enhancing efficient driving style. We compared fuel economies and levels of consumable wear on three driving simulation test (none, visual, visual+auditory). The test results show that higher fuel economy can be achieved and consumable wear be reduced when they received feedback from the proposed system compared to driving without eco-driving tra...

Hybrid vehicle fuel economy and drive quality are coupled through the “Energy Management” controller that regulates power flow among the various energy sources and sinks. This paper studies energy management controllers designed using Shortest Path Stochastic Dynamic Programming (SP-SDP), a stochastic optimal control design method which can respect constraints on drivetrain activity while minim...

Against a kind of parallel hybrid electric bus which is demonstrated in a city of China, a simulation model of the parallel hybrid powertrain system is established by referring to parameters of the demonstrating bus. Regarding the Chinese typical city bus driving cycle and the bus driving cycle of Harbin City, Heilongjiang Province as the driving cycles for the simulation, the fuel economy of t...

Energy is an inescapable part of today’s society and economy. Accomplishment of every work depends on the sufficient and incessant supply of energy. But the conventional fossil energy sources like oil are ultimately limited. Moreover, the increasing demand and flinching supply of oil has made the sustainable energy supply more vulnerable. So this vulnerability of conventional source of energy c...
