Mazda’s Smart Idle Stop System uses Direct Injection Engine Technology

September 9, 2008 The imperatives of better fuel economy and reduced emissions are breeding some fascinating developments of the good ol’ Internal Combustion Engine (ICE). One of the most logical ideas could have been invented by any schoolboy – turn off the engine when it isn’t being used. VW was the first to trial the idea and BMW, MINI, smart, Citroen and Peugeot have followed suit, all using electrical power to restart the engine, requiring beefed up starting systems to cope with ever-more-congested urban conditions (25% of European driving time is now spent at standstill). Now Mazda has come up with a better idea - restarting the engine through combustion. Mazda’s system initiates engine restart by injecting fuel directly into the cylinder while the engine is stopped, and igniting it to generate downward piston force. Read More

Honda's CRF450R motocross bike has been hugely successful since its launch in 2002 - and although the bike is already recognized as the class leader, it's receiving a kitchen-sink included upgrade for 2009. Lighter, quicker, more powerful and with even tighter mass centralization for quick handling, the 2009 CRF450R also sports a Honda first - battery-free, programmable fuel injection that raises output power and control while dramatically reducing fuel consumption. Out of the box, Honda says it's two seconds faster around a supercross track than this year's bike. Read More

August 8, 2008 Fuel injection arrived on two wheels with the release of Honda’s CX500 Turbo a quarter of a century ago, and Honda has been developing smarter and more intricate computer controlled fuel injection systems for its two wheelers ever since. These days its advanced PGM-FI (Programmed Fuel Injection) technology is fitted across the range from 50cc scooters through its MotoGP race machinery, offering broader and smoother power, better throttle response and vastly reduced fuel consumption and emissions. A prototype being quietly shown around Asia suggests that it might also lead to some lightning fast scooters in the near future. Read More
