SYDNEY: BMW introduced a new water-injection system on its M4 safety cars at the MotoGP World Championship opener in Qatar.
For the rest of the MotoGP season the M4s will be doing double-duty as safety cars and test mules, by validating the water-injection hardware in a real-world high-speed setting across a broad range of climates.
The system works by spraying a fine mist of ordinary water into the M4’s inlet tract, which then absorbs heat from the air, reduces the chance of engine-destroying pre-ignition and when the fuel/air/water mixture is ignited, turns to steam to create a bigger bang.
As its ability to absorb heat and reduce inlet air temperatures, turbo boost can be raised to further increase power.
