Simulation and assessment of power control strategies for a parallel hybrid car Tập 214 Số 7 - Trang 705-717 - 2000
Gino Paganelli, Thierry‐Marie Guerra, S. Delprat, Jean-Jacques Santin, Marielle Delhom, E Combes
The aim of this paper is to propose a power control strategy for hybrid
electrical vehicles. This strategy uses a fuel consumption criterion with
battery charge sustaining. It is based on an instantaneous minimization of the
equivalent fuel flow. Two comparisons are performed to evaluate the proposed
strategy. The first one uses the loss minimization strategy of Seiler and
Schröder [1], which appe... hiện toàn bộ
Variable compression ratio engine: A future power plant for automobiles - an overview Tập 221 Số 9 - Trang 1159-1168 - 2007
Amjad Shaik, N. Shenbaga Vinayaga Moorthi, R. Rudramoorthy
Increasingly stringent emissions and fuel economy standards have long remained a
source of challenges for research in automobile engine technology development
towards the more thermally efficient and less polluting engine. Spark ignition
(SI) engines have lower part-load efficiency when compared with the diesel
engines. The greatest opportunity for improving SI engine efficiency is by way
of highe... hiện toàn bộ
Experimental study on the combustion characteristics of emulsified diesel in a rapid compression and expansion machine Tập 214 Số 5 - Trang 579-586 - 2000
J. W. Park, Kang Y. Huh, K. H. Park
The combustion characteristics of emulsified diesel fuels are investigated in a
rapid compression and expansion machine (RCEM). Among the test cases, the 40
water-oil (W/O) fuel injected at 20° before top dead center (BTDC) has shown the
best performance with respect to efficiency and NOx and soot emissions. The
pressure trace of the 40 W/O fuel is characterized by a longer ignition delay
and a lo... hiện toàn bộ
MPC for vehicle lateral stability via differential braking and active front steering considering practical aspects Tập 230 Số 4 - Trang 459-469 - 2016
Mooryong Choi, Seibum B. Choi
This paper presents a control architecture that simultaneously utilizes active
front steering (AFS) and differential braking for vehicle lateral stability
while minimizing longitudinal perturbations. This control scheme is based on the
model predictive control (MPC) using the extended bicycle model that captures
the lagged characteristics of tire forces and actuators. The nonlinearities of
tire fo... hiện toàn bộ
Modelling and optimizing two- and four-stroke hybrid pneumatic engines Tập 223 Số 2 - Trang 255-280 - 2009
Christian Dönitz, I Parvulescu Vasile, Christopher H. Onder, Lino Guzzella
Hybrid pneumatic engines, which are designed to follow the downsizing and
supercharging paradigm, offer a fuel-saving potential that is almost equal to
that of hybrid electric powertrains while inducing much lower additional mass
and cost penalties. This paper presents a systematic optimization of the
operation of such an engine system. Both two-stroke and four-stroke modes are
analysed. The optim... hiện toàn bộ
Analysis of the overturning moment caused by transient liquid slosh inside a partly filled moving tank Tập 220 Số 3 - Trang 289-301 - 2006
Korang Modaressi-Tehrani, Subhash Rakheja, Ramin Sedaghati
A non-linear fluid slosh analysis of a partially filled circular tank is
performed to illustrate the significance of transient fluid motion on the
resulting destabilizing forces and moments imposed on the tank structure and
thus the vehicle. The analyses are performed on a clean bore tank of circular
cross-section for various fill volumes and subject to different magnitudes of
steady as well as ha... hiện toàn bộ
Experimental study of the effect of water injection on the cycle performance of an internal-combustion Rankine cycle engine Tập 228 Số 5 - Trang 580-588 - 2014
Zhijun Wu, Xiao Yu, Lezhong Fu, Jun Deng, Liguang Li
The internal-combustion Rankine cycle engine uses pure oxygen instead of air as
the oxidant during the combustion process so as to preclude the creation of
nitrogen oxide emissions. Carbon dioxide can be recovered from the water
vapour–carbon dioxide exhaust gas mixture through condensation at a relatively
low cost and, thus, an ultra-low-emission working cycle is achieved. In this
paper the worki... hiện toàn bộ
Automotive aeroacoustics: An overview Tập 231 Số 9 - Trang 1177-1189 - 2017
Nicholas Oettle, David Sims-Williams
Vehicle aeroacoustic performance has a major influence on customer perception
and also has importance for safety and comfort. Wind noise performance was once
differentiated by the quality of sealing. Today, achieving competitive wind
noise performance also depends on minimising aeroacoustic noise sources
generated by the vehicle form, and on attenuation in the noise pathway from
sources on the ext... hiện toàn bộ
