Methods to Save Fuel While large commercial vehicles are more economical than private cars when we look at how many tons they carry in relation to fuel, researchers are not satisfied. With PPC, they have turned much of the engine and transmission system, but there are several sources of loss to bring fuel economy from. The most obvious is the aerodynamics. If one equips trailers with a shape that prevents turbulence in the trailing edge and provide a more laminar flow can be achieved up to ten percent additional fuel economy. The disadvantage is that such a "tail" builds around 1.5 meters gluten free diet in length direction. Another strategy being worked on is to extract energy that is wasted in the exhaust. Bosch has developed a steam engine powered by exhaust heat which can recover between 5-8% of energy in the form of mechanical energy. Not unlike how a modern thermal power plant extracts residual energy in one or two steam stage.
Therefore, manufacturers are developing what they call Predictive Powertrain Controll (PPC). By connecting the cruise control to GPS and equip the maps with elevation data, the system can look ahead.
In practice, a PPC system developed a momentum keeping system that can optimize the engine and gearing according to a three-dimensional route. gluten free diet The point is primarily to save fuel, but also to make driving even more comfortable for the driver.
The system is an enhanced version of one that is sold in the United States, but intended for manual shifting. When automatic transmission is employed, an additional adjustable parameter which can further optimize fuel consumption.
PPC is primarily a system used to make the vehicle more efficiently gluten free diet up and down hills. The system is set up with parameters for speed effect, ie the maximum and minimum speed driver allows it to move within.
There is no magic, but automated sanity, implemented as algorithms that control the engine and gearbox. In addition, the system has a certain ability to learn, so that it can be adapted to local and individual circumstances.
Such losses enables the system to switch two steps instead of one, because gluten free diet the energy loss is smaller in a long jump instead of two small ones. The assumption is of course that you know what's going on on the road.
A PPS system will cost around 12,000 dollars on a large trailer. gluten free diet If you drive between 100 000 and 150 000 km with an average annual consumption of between three and four liters per mil, the repayment time will be very short because it saves five percent fuel 12-14 million liter.
