NASCAR could test fuel injection as early as July

Filed under: Motorsports, Technology

Chances are that just about every car you’ve ever owned featured some form of fuel injection, but the long-standard engine tech remains foreign territory in NASCAR. The sport has used carburetors since the racing series began in 1949, but that looks set to change later this year.

NASCAR reports on its website that fuel injection testing could happen as soon as July 7 at Kentucky Speedway. The date has been singled out due to the fact that this is the first time the Cup Series has raced there, and NASCAR has given racing teams an extra four hours of testing on the Thursday before the race.

Danny Lawrence, chief engine builder for Earnhardt-Childress Racing Engines, is hoping NASCAR comes up with specifications so the teams can prepare, adding “I know they’re working on it really hard, and hopefully, they’ll have it figured out in a few days.”

NASCAR is working with McLaren and Freescale Semiconductor to develop and manufacture engine control units to manage fuel and ignition systems. A wiring harness has reportedly already been developed, and the fuel-injector specification will be the next step. Teams are still wondering at this point if they’ll receive a specification for the fuel injection system or if NASCAR will provide systems that everyone must use. Hat tip to Pawager!

NASCAR to get fuel injection for 2012; McLaren wins supply contract

Filed under: Motorsports, Technology, Racing

NASCAR at Daytona

If it’s good enough for Formula 1, it’s good enough for NASCAR. Heck, if it’s good enough for every single automobile sold in the United States for the past several decades, it’s good enough for NASCAR. What’s this newfangled techno-wizardry we’re talking about? Fuel injection.

For the first time since the series kicked off in 1947, the so-called stock cars that travel full-throttle around tracks all across America will abandon their carburetors in favor of an Enging Control Unit sourced from McLaren and a computer processor from Freescale. That tandem reportedly beat out eight rival bids.

According to NASCAR Vice President of Competition Robin Pemberton, “This is a positive step that will provide greater fuel efficiency and a greener footprint while maintaining the same great competition that we have seen on the race track.”

Fuel efficiency ought to go up, as will horsepower. Interestingly, NASCAR competitors like Ford and Toyota happy about the switch. “We think it’s very important that both the cars and the technology in NASCAR are more closely related to production cars. The move to fuel injection is another important step in that process,” said Jamie Allison, Director, Ford North America Motorsports.

NASCAR expects to have its fuel injection technology all sorted in time for the 2012 season opener, the Daytona 500.

Report: Toyota plans to add turbo, direct-injection to most of lineup

Filed under: Etc., Toyota

Toyota engine production

Toyota has big plans for its model lineup, as the automaker intends to introduce 11 new or redesigned vehicles by 2012. This will be accomplished by offering hybrid versions of existing models, as well as introducing all-new hybrid vehicles. However, Toyota’s focus isn’t going to be entirely on improving the electric half of the hybrid equation. The automaker is looking at ways to produce more efficient gasoline engines, and turbochargers and direct fuel injection are both in the cards.

There’s no word yet on which models will benefit from either technology first, but the initial round of products should also come equipped with start-stop technology in addition to the DI and turbo. It was hard to believe at the time, but maybe a turbocharged, hybrid MR2 really is right around the corner.
