Ghana in recent years has seen dramatic increase in vehicular growth. Vehicular transport in Ghana is growing with increased socio economic activities. With so many cars on our roads, the rate of vehicular accident has also increased with many people died or sustained serious injuries in traffic accidents. This study reports on the brake failure and its effect on road traffic accident in the Ku...

This study investigates the use of di-ethyl ether (DEE) as an oxygenated additive with 20% Karanja methyl ester diesel blend (B20). Experiments were conducted to study the effect of adding 5%, 10% and 15% di-ethyl ether (DEE) with Karanja methyl ester (KME) on performance, emission and combustion characteristics of a direct injection diesel engine operated at a constant speed of 1500 rpm at dif...

The Particle Measurement Programme (PMP) informal working group co-ordinated a global interlaboratory study (ILS) on brake wear particle emissions with the participation of 16 laboratories in 2021. Two articles present results ILS: (I) particulate matter mass (PM) and (II) number (PN) emissions. test matrix covered different systems, including ECE NAO pad materials grey cast iron discs drum bra...

Thermoelastic instability in automotive disk brake systems is investigated focusing on the effect of a finite disk thickness. A finite layer model with an antisymmetric mode of deformation can estimate the onset of instability observed in actual disk brake systems. Also some effects of system parameters on stability are found to agree well to experimental observations. 1 Introduction Dow and Bu...

A Magneto-Rheological (MR) fluid brake is a device to transmit torque by the shear force of an MR fluid. An MR rotary brake has the property that its braking torque changes quickly in response to an external magnetic field strength. In this paper, the design method of the cylindrical MR fluid brake is investigated theoretically. The mechanical part is modeled using Bingham’s equation, an approa...

The quest for alternatefuels for a CI engine has become all the more imperative considering its importance in the economy of a nation and from the standpoint of preserving the environment. Reported in this paper are the combustion performance and P-θ characteristics of a CI engine operating on B20 biodiesel fuel derived from Jatropha oil.Itis observed that the twin effect of advancing the injec...

The adult respiratory distress syndrome (ARDS) is almost invariably accompanied by permeability pulmonary oedema, usually appearing in the first few hours [1, 2]. The extent and therefore the seriousness of this oedema is proportional to the filtration of fluid and proteins through the pulmonary vascular endothelium. The extreme sensitivity of this filtration to variations of capillary pressure...

To improve the stability and accuracy of quintic polynomial trajectory tracking, an MPC (model predictive control) fuzzy PID (proportional-integral-difference)- based control method are proposed. A lateral tracking controller is designed by using with rule-based horizon parameters. The controls steering angle to reduce errors. longitudinal a PID. motor torque brake pressure referring throttle/b...

Traction control system (TCS) comprises the slip control subsystem and the directional stability subsystem. The slip controller can enhance the traction performance by maintaining the slipratio within a proper range. Additional information about the lateral behavior of the vehicle is necessary to enhance the directional stability during the cornering or lane change on the slippery roads. With a...
