BOSCH has developed a system that cuts out the engine when the vehicle is travelling at speed, helping cut fuel consumption by 10 per cent.
With its new start-stop coasting function, the automotive components manufacturer enables drivers with combustion engines to travel in zero-emission, noise-free, and low-resistance mode over large parts of their journey.
This technology stops the engine when the vehicle is in motion, so that it does not consume any fuel.
Whenever the vehicle can maintain its speed simply by rolling, for instance on a gentle slope, the engine is stopped.
As soon as the driver touches the accelerator or brake pedal, the engine starts up again.
Tests carried out by Bosch have shown that the combustion engines runs needlessly about 30 per cent of the time, meaning that the vehicle could simply coast for about a third of every journey.
As a result, and under real traffic conditions, the newly-developed function would give drivers a roughly 10 per cent fuel saving.
The start-stop starter has been configured to cope with greater loads and to deliver faster restarts.
It requires few additional components and can be integrated in almost any vehicle in the world, the German company claims.
“Bosch is confident that start-stop coasting will soon become an everyday feature in cars just like air conditioning,” said Rolf Bulander, member of the board of management of Bosch.
