A Study on the Optimum Reduction of Required Brake Fluid Level for Improvement of The High Speed Continuous Brake Distance

2019-09-15
2019-01-2121
The high speed continuous braking distance assessment is the worst condition for thermal fades. This study was conducted to investigate the relationship between fade characteristic and friction materials & brake fluid amount for improving braking distance. So, we used the dynamometer to measure the friction coefficient, braking distance and required brake fluid amount. First of all, we studied the influence of friction coefficient on the same friction material shape (chamfer shape, area of the friction material, number of slots). Secondly, we knew the effects of braking distance by the shape of the friction material. Through these two studies, the shape of the friction material favorable to the fade characteristics was obtained. Finally, we measured the amount of required brake fluid in caliper after 10 consecutive braking cycles through Dynamometer. And then, we measured the amount of compression deformation and uneven wear of the friction material.

Development of a Dedicated CNG Three-Way Catalyst Model in 1-D Simulation Platforms

2019-09-09
2019-24-0074
A growing interest in heavy-duty engines powered with CNG dictated by stringent regulations in terms of emissions, has made it essential to study a specific Three-Way Catalyst (TWC). Oxygen storage phenomena characterize catalytic converter efficiency under real world driving operating conditions and, consequently, during strong dynamics in Air-to-Fuel (A/F) ratio. A numerical “quasi-steady” model has been set-up to simulate the chemical process inside the reactor. A dedicated experimental campaign has been performed in order to evaluate the catalyst response to a defined lambda variation pattern of the engine exhaust stream, thus providing the data necessary for the numerical model validation. In fact, goal of the present research activity was to investigate the effect of very fast composition transitions of the engine exhaust typical of the mentioned driving conditions (including fuel cutoffs etc.) on the catalyst performance and on related emissions at the tailpipe.
