Poor atomization and ignition difficulty due to the deterioration of environmental conditions restrict the coldstart
performance of diesel engine. To investigate how the ambient and injection parameters affect diesel ignition characteristics
at low temperature and density, liq...
This paper proposes an optimal path planning algorithm to make the autonomous vehicle follow the desired
path profile while avoiding nearby obstacles safely. Also, it utilizes only readily available sensors equipped with typical
autonomous vehicle system. For optimal path plan...
The design of new energy vehicle load-bearing structural components using traditional experience may lead to
low material utilization efficiency. This makes it difficult to reduce the quality, or material shortage, which will increase the
number of product design iterations an...
As an alternative to the conventional concave hexagonal honeycomb structure (CHHS), a negative Poisson’s
ratio honeycomb structure with power function curve (NHPC) was devised. The relationship between the power function
exponent (PFE) and normalized power function coefficien...
Safety evaluation method for the intersection forward collision-avoidance assist (I-FCA) function is presented
in this work. The I-FCA function can prevent traffic accidents in intersections by applying warning and brake when the radar
and vision sensor can detect risk of coll...
Lightweight electric vehicles (LEVs) possess great advantages in the viewpoint of fuel consumption,
environment protection and traffic mobility. However, due to the drastic reduction of vehicle weights and body size, the
effects of payload parameter variation in LEV control an...
The battery system of a vehicle is critical for its good operation, and in the event of vehicle collision, damage
to the parts or displacement of the battery can significantly affect performance. Nonlinear characteristics must be considered
when designing elastic parts for veh...
The center of gravity of a forklift truck, a crucial parameter for vehicle stability, changes with different loads
during operation. We propose an estimation algorithm for the center of gravity position suitable for a counterbalanced forklift
truck. By installing sensors on th...
Water-in-diesel emulsion fuel has become a popular alternative fuel for diesel engines. The main limitation is
related to its stability, whereby it relies heavily on surfactants to remain homogeneous, therefore causing production costs to
rise. This paper highlights the applic...
ABSTRACT–overcome these
problems, the automobile industry is prioritizing the development of eco-friendly vehicles that reduce greenhouse gas emissions.
Among these, fuel-cell electric vehicles (FCEVs) use hydrogen as a fuel and do not emit exhaust gas and their higher mileag...
In response to the continually increasing thermal load caused by the rising gas temperature in the inlet of
radial-flow turbines, this paper proposes the use of axial hole air-entraining cooling to cool the turbine shaft and turbo wheel
back-disc. The cooling effect of this te...
Combustion noise accounts for a large proportion of diesel engine noise. On the premise of not increasing the
cost of diesel engine, the injection system parameters such as dynamic fuel supply advance angle and needle valve opening
pressure are optimized, and the influence of ...
For avoiding knock occurrence in SI engines, spark timing is retarded whenever the knock has occurred which
leads to a loss of thermal efficiency. Therefore, the knock occurrence needs to be properly controlled. For doing that, knock
should preemptively be predicted and contro...
Under the background that electric vehicles cause enormous supply pressure on the grid, the application of
vehicle-to-grid (V2G) technology can effectively alleviate supply pressure and also bring more economic benefits.
Considering conditions for participating in V2G, pure el...
To suppress CO2 emissions through policies and technology development, eco-driving techniques are required
to be actively practiced as an effective method to improve fuel efficiency. Among the methods to practice eco-driving, the
active eco-mode is a function that changes the ...
The aim of the work was to develop a multi-body model that can simulate the impact between the vehicle
wheel and a pothole. The model consists of the vehicle wheel together with front McPherson suspension assembly and a
potholed road surface. Therefore the kinematics of the su...
Performance of battery cells in an electric vehicle (EV) highly depends on environmental temperature.
However, many studies do not consider its regional or seasonal characteristics. These characteristics can have a significant
impact on the EV battery life in California, where...
An experimental investigation was conducted in this study to assess the effect of the front toe angle and tire
pressure on the fuel efficiency of light-duty vehicles. According to the investigations, increasing the toe angle results in an
increase in rolling resistance, which ...
