Small Changes, Large Results
Tuesday, October 30th, 2007While this journal often focuses on game-changing technology like hydrogen fuel cells or electric vehicles, it is important to also recognize how automakers are doing to update today’s technology for maximum efficiency gains. The Detroit Free Press recently ran an article about some of these advances.
One of these technologies is direct gasoline injection, a process that injects the exact right amount of fuel needed in an engine using a high pressure pump and special electronic systems. This fine-tuning of the engine can yield massive gains in horsepower while also raising the vehicle’s fuel efficiency achieving more power and better gas mileage.
Another advancement the article discussed was dual clutch transmissions. The dual clutch operates like a manual transmission which gets about 6 percent better gas mileage than a standard automatic transmission. A vehicle equipped with both direct injection and a dual clutch could get 10 percent better fuel economy or as much as putting a mild hybrid into the vehicle. While these technological changes seem fairly minor they can add up to make a major difference in fuel consumption and emissions.
