Legislation to both reduce truck CO
2
output and improve fuel efficiency is
unfolding. In response, engine and vehicle
OEMs are developing technology that
recovers exhaust heat, using it to boil a
working fluid. The vapour generated is
expanded to produce additional power
for every litre of fuel consumed.
Our EHR fluid control experts are developing unique valve
solutions to control the flow of liquid, vapour, exhaust
gases and coolant in Rankine Cycle heat recovery
systems – which will become standard fit on long haul
trucks and high usage engines in the near future.
Working within a number of OEM development
programmes, we have supplied 1st generation valves
for use with both water and ethanol working fluids.
These valves are unique in the industry, being:
> Sealed for life
> Inherently safe
> Proportional
> Multi-functional
> High performance
> Designed for truck applications
The designs enable more energy to be recovered
than with existing valves. With the next generation in
development, size, cost and weight are reduced whilst
performance characteristics and durability are improved.
Our success is the result of extensive investment in both
people and ethanol-capable facilities. Late in 2014, a bespoke
Rankine System test cell was unveiled, linked with a state-
of the art simulation model, the cell enables components to
be tested and characterised, whilst validating the additional
system performance benefits of using our valves.
The future is…
exhaust heat recovery
