Best economy (lean of peak or LOP) operation of aircraft engines rather than best power (rich of peak or ROP) has been suggested as a means to reduce fuel consumption in light aircraft with modest speed reduction leading to reduced operating cost (increased miles per gallon), and to reduce cylinder head temperatures (CHTs) leading to improved engine longevity and reduced maintenance cost. A rec...
This paper presents the evaluation of a new onboard system designed to reduce fuel consumption and CO2 production. GERICO system enables the driver to adopt the best driving behaviour, smooth speed and good gear management. We carried out 80 tests (40 baselines, 20 with training and 20 with GERICO) with 40 drivers in the Toulouse area. The main results show that training contributes to a 12% co...
Introduction: Motor vehicles are known as an important artificial source of air pollution, where personal cars account for 90% of total consumed energy in transportation system. Human factors have a critical role in car-caused air pollution. Therefore, the present study was conducted to evaluate knowledge, attitude and practice (KAP) of drivers towards reduction of fuel consumption and control ...
Greenhouse gas emitted by the transport sector around the world is a serious issue of concern. To minimize such emission the automobile engineers have been working relentlessly. Researchers have been trying hard to switch fossil fuel to alternative fuels and attempting to various driving strategies to make traffic flow smooth and to reduce traffic congestion and emission of greenhouse gas. Auto...
Introduction: Replacingfuel oil with natural gas in brick kilns is one of the effective ways to reduce air pollution as well as the cost of the furnaces maintenance. The aim of this study isto estimate reduction of air pollutants resulting from brick kilns functioning with natural gasin Yazdprovince. Methods: In this descriptive-survey research, we estimated consumption of the fuel oil in the ...
Challenges facing fuel cell hybrid vehicles is in implementing a control strategy to find the optimal split of power between the different power sources. This paper proposes a mathematical model of power flow in such vehicles taking into consideration power train losses. Linear programming locates the global optimum indicating the finest synchronization among power units in an attempt to lower ...
the primary objective of this work is to introduce a gear ratio selection strategy for a CVT equipped vehicle and show its effectiveness on the fuel consumption reduction. AFuzzy control algorithm is designed for this purpose. Anonlinear model is developed for simulating the longitudinal vehicle dynamics with accelerator pedal applied by the driver as an input. In order that pedal input valu...
