Small engine platform

  • 04-Jun-2010 02:11 EDT

To address the global need for eco-friendly designs in the small engine market, Freescale combines an integrated analog device with a 16-bit microcontroller (MCU) to provide a platform solution suitable when migrating from mechanical carbureted systems to electronic control and electronic fuel injection (EFI). The small engine control platform consists of the MC33812, an analog integrated circuit to control fuel and spark in EFI and electronic carburetion systems, and a Freescale S12 MCU. Benefits include reduced emissions and system complexity, increased engine power, and improved time to market, while suitable applications include small-displacement two- and four-stroke engines used in motorcycles, mopeds, and scooters, as well as small engines in various outdoor power equipment, such as mowers, tractors, trimmers, chainsaws, blowers, tillers, and outboard motors. EFI systems on small engines can reduce carbon monoxide emissions by up to 65% compared to carburetor systems, according to Freescale.
