recent years, commercial fleet vehicle technology has seen significant
advancements aimed at enhancing sustainability and reducing total ownership
costs. Central to this discussion are Automatic Tire Inflation Systems (ATIS),
which have emerged as a key technology in pursuit of these goals.
Efficiency and Environmental Impact:
key advantage of ATIS is the potential for increased fuel efficiency. Several
studies have demonstrated that improper tire inflation can lead to increased
rolling resistance, thereby reducing fuel efficiency by up to 3%.
ATIS mitigates this by continuously maintaining optimal tire pressure, thereby
decreasing fuel consumption and lowering CO2 emissions.
to the Environmental Protection Agency (EPA), the transportation sector is the
largest contributor to greenhouse gas emissions in the United States,
accounting for approximately 29% of total emissions.
By improving fuel efficiency and subsequently reducing CO2 emissions, ATIS
represents an impactful strategy for sustainability.
Costs and Tire Lifespan:
costs constitute a significant proportion of TCO for commercial fleet vehicles.
ATIS can reduce these costs by maintaining optimal tire pressure and thereby
reducing tire wear. According to the Technology & Maintenance Council
(TMC), tires under-inflated by just 10% can reduce tire life by up to 16%.
With ATIS, the tire pressure is consistently maintained, significantly
extending tire lifespan and reducing replacement costs.
Cost of Ownership (TCO):
evaluating TCO, fuel efficiency, maintenance costs, and tire lifespan are
essential factors. However, we also consider downtime (unplanned repairs or
replacements) and its consequential impact on productivity. Given the impact of
tire under-inflation on premature tire failure, the value of ATIS in reducing
downtime is substantial.
and Future Perspectives:
ATIS offers notable advantages, initial setup costs can be higher than standard
tire inflation systems. However, a lifecycle cost analysis reveals that the
initial investment can be recovered through reduced maintenance costs and
extended tire lifespan. Future research should explore cost-effective ways of
integrating ATIS into fleet vehicles at the manufacturing stage, potentially
lowering initial setup costs.
most ATIS currently available rely on pneumatic technology. Future systems may
leverage advancements in sensor technology and data analytics to provide
real-time diagnostics, prognostics, and self-healing capabilities, offering
further savings in maintenance and potential enhancements in safety.
in commercial fleet vehicle technology, particularly ATIS, offer considerable
benefits in terms of sustainability and reduced TCO. This is achieved through
improved fuel efficiency, reduced maintenance costs, extended tire lifespan,
and less downtime. Despite higher initial setup costs, the total lifecycle cost
benefits justify the investment.
work should aim at lowering the initial setup costs and exploiting emerging
technologies to further enhance the benefits of ATIS.
