Mazda has just garnered another award for its new i-stop system that debuted this year on the Axela (3) and Bianti MPV. This is Mazda’s take on an automatic start/stop system to eliminate idling but with a novel new twist. Rather than just use a more robust starter and battery to crank up the engine every time you pull away from a stop, it takes advantage of the direct injection. The engine is stopped in a specific position each time (one of the pistons just below top dead center on the power stroke) and fuel is sprayed in directly and ignited. The expansion of the burning gas gets the piston moving and fires the engine with less strain on the starter.
Mazda has been recognized by the Japanese Ministry of Land, Infrastructure, Transport and Tourism with one of its Eco-Product awards for 2009. Like other start stop systems, i-stop can provide up to a 10 percent reduction in consumption in urban driving thanks to the idle reduction.
