Record baseline figures
Route, load and previous fuel records set the comparison framework.
Fuel-consumption optimisation
Efficiency starts with how you use it.
Eco tuning focuses on usable torque and your driving profile. What matters is the change in actual operation.
CARS, VANS AND COMMERCIAL VEHICLES
Matched to your driving
instead of blanket figures.
Long journeys, stop-start traffic and towing load an engine differently. A torque characteristic matched to use can help make suitable operating points usable and avoid unnecessarily high engine speeds.
This does not imply a fixed fuel saving: driving style, payload, route profile and technical condition affect the result. Frequent use of extra power may increase fuel consumption.
THREE AREAS OF ENGINE CALIBRATION
How software can make a difference.
- 01
Injection optimisation
Injection quantities and timing are considered together with load, engine speed and air supply. Calibration must suit the combustion process.
- 02
Refining ignition timing
On petrol engines, suitable ignition timing can influence combustion. Fuel quality, knock control and component protection set limits.
- 03
Matching air and fuel
Air and fuel delivery are assessed together. A suitable mixture depends on operating conditions and exhaust-aftertreatment requirements.
MAKING THE COMPARISON MEANINGFUL
The same task.
Measurable consumption.
Define appropriate goals
We weigh pulling power, engine-speed range and everyday usability together.
Measure again in operation
Comparable operating conditions and several measurements are more meaningful than a single trip.
Efficiency needs a healthy engine.
Fault memory, maintenance and existing problems are assessed before calibration. Tuning does not replace repairs. Lower fuel consumption is not general proof of reduced NOx or other pollutant emissions.
