| description |
Automotive tyre plays an imperative aspect in ensuring safety, economical and performance of a motor vehicle which indeed the only medium that merge the contact between a car and asphalt. According to studies and statistics by giant tyre manufacturers,one of the primary reasons for major road accidents which often leads to loss of life is the
catastrophic tyre failure caused by vehicles running with improper tyre pressure due to lack of attention on tyre maintenance. The phenomena where tyre loses pressure naturally and contracts over time is called air permeation, which is identified to be the main cause of tyre to deflate but rarely can be realised by naked eyes. Properly inflated tyres can safe tyre life up to 20% which is equivalent to nine months of its life span, save fuel from 4% to 10%,
increase braking efficiency up to 20%, lightens steering system and ease self-steer. Since the day pneumatic tyres were invented, sudden losses of air acts as a major problem
associated with tyres and are still being treated by professional tyre researchers. Besides external punctures which cause tyre deflation, other crucial factors which contribute to natural pressure loss are investigated in this study such as the properties of inflated air,
pressure leak through mechanical fittings and ultimately excessive tyre operating temperature which promotes air permeability over time. Fundamental experimentation to
study the behaviour and characteristic of pressure loss of a normal tyre was conducted in both static and dynamic conditions where they were also tested with and without loaded situation to extract precise data of the pressure loss. It is noticed that a normal tyre losses 5kPa to 10kPa of pressure a month at static condition and 15kPa to 20kPa at dynamic condition. Nowadays, usage of tyre sealants which contains Ethylene Glycol or Propylene Glycol as a countermeasure to curb the issue becomes an ideal solution and current trend but reflects several drawbacks namely on the performance, properties and characteristic of the sealant. In order to improvise the currently available solution, a relevant bio-based additive sealant that tailor to the situation have been initiated using Bio-Glycol as a way forward total solution suiting a wide range of tyres used on domestic cars sequentially sustaining the tyre pressure and further reducing the natural air permeation rate to stop tyre deflation by means of controlling the tyre operating temperature. The proposed solution have been further tested comprehensively in a dynamic condition along other available solution in the market with aid of Tyre Pressure Monitoring System (TPMS), which then leads to the development of a data logging structure of each tyre pressure and temperature using LabVIEW graphical user interface. Concurrently, the physical and chemical properties of the solution have been generated as a validation to reflect its basic performance. Finally, the proposed solution shows promising result in controlling tyre
temperature and ultimately reducing tyre pressure loss over time subsequently meeting the standard regulation of a proper tyre sealant. |
