This paper presents a design procedure for an adaptive power management control strategy based on a driving cycle recognition algorithm. The design goal of the control strategy is to minimize fuel consumption and engine-out NOx, HC and CO emissions on a set of diversified driving schedules. Seven facility-specific drive cycles are considered to represent different driving scenarios. For each fa...

An estimated 2.6 billion people rely on traditional biomass for home cooking and heating, so improving the efficiency of household cookstoves could provide significant environmental, social and economic benefits. Some researchers have estimated that potential greenhouse gas emission reductions could exceed 1 billion tons of carbon dioxide equivalent (CO2e) per year. Carbon finance offers a poli...

Diesel engine is known for its durable operation and capability of utilizing various type fuels, however, dangerous exhaust emissions are emitted from diesel engines. Non-surfactant emulsion fuel a potential to reduce Nitrogen oxides (NOx) Particulate matter (PM) emission compare conventional in engine. In this study, was prepared using mixer as Circulation Non-Surfactant Emulsion Fuel System. ...

Diesel engines being inferior in their emission characteristics are under greater scrutiny. Intensive research efforts are ongoing for improving fuel consumption and exhaust emissions from diesel engines. For improving performance of engine, Ceramic based Thermal barrier Coating plays a major role. Tests were performed on four stroke, single cylinder, DI diesel engine whose piston crown, cylind...

The quantification of aircraft level benefits like the reduction of mass, drag, power offtake, and consequently fuel burn is a key aspect in assessing new technologies like green taxiing systems, electrical environmental control systems, and optimized aircraft trajectories. A basic means to determine these deltas is a detailed dynamic model of the aircraft containing the flight dynamics, kinema...

In China, coal combustion to generate electric power is the primary method, the energy-saving and emission reduction is the urgent task. At present, the energy-saving dispatching trial method in some area evaluates energy-saving and emission reduction of coal combustion power generation according to power supply coal consumption rate only. But the power supply coal consumption rate can’t reflec...

Gasoline Direct Injection (GDI) spark ignition engines equipped with the Common Rail (CR) system strongly improve engine performance in terms of fuel consumption and pollutant emission reduction. As a drawback the fuel pressure in the rail has to be kept as constant as possible to the demanded pressure working set-points in order to achieve the advantages promised by this technology. In this wo...

We develop a two-region partial equilibrium model of the global market for liquid fuel and analyze different policies, such as biofuel mandate, emission standard, and fuel carbon tax. We rank these policies under different criteria, such as greenhouse-gas (GHG) emissions, expenditure on fuel imports, the impact on fuel consumers and producers, the quantity of biofuel, etc. Our analysis suggests...

Alternative fuels have received much attention due to the depletion of world petroleum reserves and increased environmental concerns. Thus processed form of vegetable oil (Biodiesel) offers attractive alternative fuels to compression ignition engines. The present work investigates the engine performance parameters and emissions characteristics for direct injection diesel engine using coconut bi...
