The Impact of Digital valves on the future of combustion engine.
Want to know what is a Digital Valve ?.
Efficient hunting of engine valve technology can be endless trips to cam
timings, various combustion cycles, and lift and duration adjustments.
For that reason, some companies believe cam-less is a vision of future
engine efficiency. British clothing by the name of Camcon Automotive sees this
problem from a different angle. The electric, actually, as a prototype machine
is the first example to be run with a valve that is completely digitally
controlled.
The Camcon approach to valve timing is very different. This is called
Intelligent Valve Technology and utilizes a valve that is not connected to the
crankshaft, so that the valve itself can operate independently.
In addition, each valve has its own small camshaft, in contrast to the
larger single or double camshafts usually found to control the entire valve
bank. A miniature camshaf is controlled by an electric motor, and that
interaction tells the valve how to behave.
Settings allow for precise (and timely) changes to lift and duration,
which describe the number of open valves and how long they remain open.
There
is no compromise found for engines that want low-end power, fuel savings in a certain range of rotation, or have emission requirements at the top end where
the engine wants to spin.
For automakers, the ability to adjust the valve time under a vehicle the operation allows power balance, emission control, and proper fuel economy. When
needed, such as during heavy throttle loads, the engine adjusts the timing of
the valve for a more aggressive combination of air and fuel and provides more
power.
An opposite situation will occur
during a partial throttle application. When vehicles maintain a consistent
speed on the road, for example, the valve timing will be focused on producing
the best possible fuel savings.
Although all of these adjustments are controlled by electronic sensors,
the actual valve adjustment is mechanical.
This is not a variable valve time. This is possible for unlimited valve
timing. Camcon has tested the system for thousands of hours on a dyno engine,
according to a report on the New Atlas. At present, the company is working to
combine multi-valve arrangements but has seen an increase in CO2 emissions for
the Ingenium Jaguar engine which serves as the basis for testing.
Beyond the basic on-the-fly valve timing, Camcon says it can run the
engine as if it were a two-step arrangement. In turn, it will potentially
double the power output for a short burst. At the other end of the spectrum see
the engine running as if it were 12-stroke.
That would allow for extraordinary
profits in the fuel economy space.
At present, more testing is needed before automakers start incorporating
this technology into their own machines. But this is automotive technology that
is noteworthy.
