TL;DR: This work proposes a transdisciplinary framework to determine ecological redline areas (ERAs) in Shanghai using ES, biodiversity and ecologically fragile hotspots, landscape structure, and stakeholder opinions and determines the five criteria to identify ERAs for Shanghai using multi-temporal, high resolution images and biophysical models.
Abstract: Ecosystems services (ES) assessment is a significant scientific topic recognized for its potential to address sustainability issues. However, there is an absence of science–policy frameworks in land use planning that lead to the ES science being used in policy. China’s Ecological Redline Policy (ERP) is one of the first national policies utilizing multiple ES, but there is no standardized approach for working across the science–policy interface. We propose a transdisciplinary framework to determine ecological redline areas (ERAs) in Shanghai using: ES, biodiversity and ecologically fragile hotspots, landscape structure, and stakeholder opinions. We determine the five criteria to identify ERAs for Shanghai using multi-temporal, high resolution images (0.5 m) and biophysical models. We examine ERP effectiveness by comparing land use scenarios for 2040. Compared to alternative land uses, ES increase significantly under the ERP. The inclusion of ES in spatial planning led stakeholders to increase terrestrial habitat protection by 174% in Shanghai. Our analysis suggests that strategic planning for ES could reduce tradeoffs between environmental quality and development. Ecosystem services, though a prominent ecological concept, have yet to be considered in major land use policy changes. Here, the authors demonstrate how the Ecological Redline Policy implemented in Shanghai utilized ecosystem services science and stakeholder engagement.

18 Aug 1994TL;DR: In this article, a method for comprehensive integrated control of a compression-ignition internal combustion engine having integral fuel pump-injectors utilizing an electronic control unit (20) is disclosed.
Abstract: A method for comprehensive integrated control of a compression-ignition internal combustion engine having integral fuel pump-injectors utilizing an electronic control unit (20) is disclosed. The control strategy integrates various functions of engine control including fuel delivery (34), cooling fan control (38), engine speed governing and overspeed protection, engine braking, torque control, and vehicle speed diagnostics and control. Cooling fan control (38) is integrated with vehicle speed diagnostics and control as well as fuel delivery (34) to provide an integrated cruise control function which incorporates engine braking. The method also includes improved control over the various engine speed governors while improving idle quality by balancing the power delivered by each of the engine cylinders when at idle. The integrated torque control employs functions to reduce NOx emissions and noise utilizing adaptive fuel delivery timing and a split injection strategy.

11 Sep 2007TL;DR: In this article, the authors provided a method and article of manufacture for operating an internal combustion engine adapted to transmit torque to a hybrid transmission, and the method comprises determining an engine input torque transmittable to the hybrid transmission for a plurality of engine states, the engine states comprising a fueled engine operation and an engine fuel cutoff operation.
Abstract: There is provided a method and article of manufacture for operating an internal combustion engine adapted to transmit torque to a hybrid transmission. The method comprises determining an engine input torque transmittable to the hybrid transmission for a plurality of engine states, the engine states comprising a fueled-engine operation and an engine fuel-cutoff operation. Costs are determined costs for operating the engine and hybrid transmission in the engine states to substantially meet an operator torque request. The engine state is controlled to one of the fueled-engine operation and the engine fuel-cutoff operation based upon the costs.

TL;DR: In this paper, a computerized 2 and 4 cycle internal combustion engine control and optimization/tuning system is disclosed, wherein fuel injector control is optimized to increase horsepower and fuel economy.
Abstract: A computerized 2 and 4 cycle internal combustion engine control and optimization/tuning system is disclosed, wherein fuel injector control is optimized to increase horsepower and fuel economy. The system is comprised of an on-board engine controller with communications software allowing technicians to change external sensors via an external computer. The technician may tune engine parameters on the fly as the engine is running. The engine control system displays engine-operating parameters in real time. Fuel mapping can be for the operator's choices of acceleration, maximum speed, gas mileage, altitude of operation and/or engine temperature.
