Solenoid controller improves efficiency of direct fuel injection engines

January 14, 2014 // By Christoph Hammerschmidt
Worldwide, legislation requires automakers to improve fuel efficiency and meet tougher emissions standards in the next future. To help automakers and suppliers comply with these requirements, Freescale Semiconductor offers the MC33816 programmable solenoid controller, designed to reduce emissions and improve fuel efficiency for both gasoline and diesel direct fuel injection engines. The architecture is also applicable for driving dual clutch transmissions, as well as precision solenoids in factory automation applications.

The MC33816 programmable solenoid controller embeds intelligence with four integrated µCores, enabling four parallel tasks to run independently of the main system microcontroller. The result is a response time up to 16x faster than traditional architectures, thereby improving engine efficiency with precise fuel delivery that reduces fuel use.

The device's functional integration enables substantial bill-of-materials reductions and provides the flexibility and scalability necessary to be integrated into virtually any engine system, including gasoline, diesel, flex-fuel and even LNG engines, regardless of the number of cylinders.

The MC33816 controller additionally provides embedded encryption and microcode protection to inhibit reverse engineering and help safeguard system IP and software.

The vendor provides hardware and software to support the MC33816 programmable solenoid controller. The KIT33816AEEVM evaluation board allows utilization of the controller’s functions and is available now at
