Tutoring System for the Efficient Driving of Combustion Vehicles

IEEE Revista Iberoamericana de Tecnologias del Aprendizaje, 2013
One of the sectors that currently generates pollution is road transport. Every day, millions of tons of CO2 are released into the atmosphere because of this type of human activity. Governments see the reduction of such emissions as a priority-which, according to various studies, could be achieved through more efficient driving.

Combustion Efficiency Impacts of Biofuels

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2009
Abstract The term biofuel is referred to as liquid fuels for the transport sector that are predominantly produced from biomass. Biofuels are important because they replace petroleum fuels. There are many benefits for the environment, economy, and consumers in using biofuels.

Efficiency of Combustion Plant

1994
In Chapter 4 the idea of an energy balance around a combustion system was introduced and developed to give a simple procedure for calculating the adiabatic temperature of a flame. The general energy balance of the system was $$CV + {H_R} = {H_{\text{P}}} + {Q_{\text{c}}} + {Q_{\text{u}}}$$ (6.1) and this expression can be used to explore the ...

Efficient and Clean Diesel Combustion

SAE Technical Paper Series, 1975
<div class="htmlview paragraph">Since the available combination of equations describing the kinetic reactions during diesel combustion a) is complicated, b) falls short in predicting actual NO-emissions, an attempt is made with a simplified model to correlate the squared temperature profile of the cycle over time, integrated above the level of a ...

The influence of combustion efficiency on the characteristics of ramjets

High Temperature, 2016
Methods for determining the combustion efficiency, thermodynamics parameters of propellants, and characteristics of ramjets are analyzed. Energetic and multizone models taking into account various physical processes of incomplete combustion are considered.

Efficient catalytic combustion in integrated micropellistors

Measurement Science and Technology, 2009
This paper analyses two of the key issues of the development of catalytic combustion-type sensors: the selection and production of active catalytic particles on the micropellistor surface as well as the realization of a reliable thermal conduction between heater element and catalytic surface, for the sensing of temperature increase produced by the ...

Zirconium combustion efficiency in energetic compositions

Russian Journal of Physical Chemistry B, 2014
The combustion solid-fuel samples containing zirconium or zirconium hydride, octogen (HMX), and an active binding agent was studied. On varying the particle size of zirconium, it was found that the rate of combustion of a composition at a pressure of 40 atm essentially depended on the particle size of zirconium: the rate of combustion increased by a ...

Efficiency of a combustion reaction in power production

The Journal of Chemical Physics, 1988
We analyze a thermal engine in which the source of heat is the combustion reaction CH4+2O2→CO2+2H2O. The efficiency of the thermal engine is defined as the ratio of the power output of the engine to the power input. We compare the efficiency in two modes of operation, one in which the input and output of chemical species are constants and one in which ...

Gas Turbine Combustion Efficiency Calculations

Aircraft Engineering and Aerospace Technology, 1950
THE alternative definitions of combustion efficiency based on the ratio of actual to theoretical heat releases and of theoretical to actual fuel requirements are discussed in relation to the practical need for reckoning enthalpies above a datum temperature.

Effects of combustion efficiency on a Dual cycle

Energy Conversion and Management, 2009
Abstract This paper studies a Dual cycle model containing irreversibilities coming exclusively from expansion and compression processes. It is assumed that any fraction of the fuel’s chemical energy can not fully released inside the engine because of the incomplete combustion.
