CAMBRIDGE, England – Heavy-duty diesel truck fleets could save millions of pounds in fuel costs and commercial vehicle manufacturers could meet increasingly stringent emissions regulations by adopting digital engine technology from Camcon Automotive.
”Intelligent” valve technology, the company explains, replaces the engine’s camshaft with electronic actuators for precise control of the engine’s breathing when combined with innovative software,
Camcon says its cost-effective concept create a major change in powertrain development by dramatically reducing fuel consumption and emissions without any need for OEMs to invest in electric vehicles.
‘BIG LEAP FORWARD’
A Camcon tech consultant, Neil Butler, told The Corner in a media communication: “All key combustion process parameters have been under digital control for some time but breathing has been stuck under the control of increasingly complex but essentially mechanical variable valvetrain systems.
”Now iVT is as big a leap forward as the change from carburettors to electronically controlled fuel injection.”
IVT, he added, gave infinite control over the valves to benefit HGVs – from cold-start emissions through exhaust re-circulation to
on-demand cylinder deactivation and management of harmful pollutants such as NOx.
iVT could be used to reduce significantly the size, weight, and cost of the after-treatment equipment fitted to a heavy-duty diesel engines and better control exhaust after-treatment temperature.
Catalysts, The Corner was told, can be maintained at their optimum operating temperature over a greater part of the drive cycle and, while iVT cannot eliminate after-treatment equipment entirely, it can reduce the size and cost and weight.
”For instance, thanks to the system’s greater optimisation of emissions control, a truck would not need to use as much AdBlue.”
Most significant, however, was a ”significant” cut in fuel consumption: Camcon believes it can improve the efficiency of the average heavy diesel truck by five percent.
GIANT FINANCIAL SAVINGS
”For just one truck that would save almost £2500 (about R52 000) a year in diesel,” Butler claimed. ”Extrapolated across the entire UK haulage fleet, iVT could save the industry close to half a billion pounds in diesel every year.
”With more than three million heavy duty diesel trucks sold worldwide and each vehicle having a lifetime of more than 10 years it is very easy to see just how much of a massive effect our system could have.”
