Asinine Engineering: Direct Exhaust Injection

Hang around internet fora dedicated to increasing internal combustion performance long enough and you'll eventually run across this type of perpetual-motion misunderstanding. Seems a Vette 'boarder over at the GMModernMuscle Forum needs to study up on several principles before heading out half-cooked, wrench in hand. The brilliant idea that dawned above the poster's head like a 3-watt bulb was that instead of messing around with those ever so inefficient turbochargers, it'd be a simpler route to

MIT helps Ford apply pressure

Ford is looking for ways to pack their automobiles with innovative technology that achieves the seemingly impossible goal of using smaller, more efficient engines while still delivering the performance wallop customers are demanding. Not only is the Blue Oval seeking more involvement from their suppliers to push new technology and techniques forward, but the automaker's also looking outside the typical realm of automotive OEMs.

Vintage Tech: The Granddaddy of EFI

Every car on the road now has fuel injection. There was no real battle royale between electronic systems and mechanical, though both flavors saw plenty of development. Rochester's Ramjet system was effective and quite slick, contained in a special intake manifold. Bosch had K-Jetronic which was a mechanically metered system that later gained some feedback electronics, becoming the very first FI system to utilize an exhaust gas oxygen sensor for fine mixture control. Fuel injecti

Piezo injection technology breaks into top engine list

Siemens VDO has announced that for the first time an engine equipped with piezo direct injection gasoline (DIG) technology has featured in Ward's 10 Best Engine List of 2007. The 300 hp / 224 kW BMW 335i Twin Turbo 3-liter engine, which features Siemens VDO DIG technology, was unveiled at the Geneva Auto Show last year.
