The gauge still said empty. The vsc, check engine, and hybrid system failure indicators where on - but not the low fuel!!! Overall, it is a good thing, since it reduces pollution. The notion behind the bladder was to control evaporative emissions of gasoline fumes. Toyota decided to ditch the environmentally friendly bladder in part because some Prius owners complained that the collapsible container held much less fuel than the 11. Then, on January 16th, I had a tank that was nearly empty.
The Prius technically has an 11. That's more than 10 percent of the tank's stated 11. Mine is linear and consistent. This is not a satisfactory response to a safety issue. That new hardware lets the 2010 Toyota Prius keep its rating as a low-emission vehicle under the state of California's stringent standards for volatile hydrocarbon fumes.
Thus there are both benefits and problems with it. Slowing down without warning is as dangerous as accelerating without warning. In a related issue, some owners said the flexible tank's fuel gauge tended to signal prematurely that the tank was close to empty. The new 2010 Prius uses a conventional, rigid tank, albeit one made of lightweight reinforced resin rather than steel. Toyota Prius gas cap In switching to a standard rigid tank, Toyota added a conventional vapor-recovery system. The Prius' new fuel tank will use an improved vapor-recovery system that will allow the car to retain its low-emission rating from California regulators, Kwong said. If this should happen on a highway, it could easily be fatal.
The tank was empty, I put a few gallons of gas in the tank and it did not register at all. The colder it is outside, the less flexible the bladder is, which means that you can't put as much gas in the tank. By collapsing as fuel is pumped to the engine, bladders help prevent fuel vapor from building up in the tank, thereby reducing hydrocarbon emissions. The new 2010 Prius -- the third generation of the groundbreaking gas-electric hybrid -- will use a rigid tank made of a lightweight resin rather than the bladder. The Prius gets 46 miles per gallon in combined city-highway driving, according to government figures.
As for the fuel gauge, maintenance manuals say recalibrating it can sometimes solve the problem. . The gas tank bladder prevents air in the tank from coming in contact with the gas. Was fortunate enough to be on a section of the bridge with a breakdown lane. The Prius owners' manual notes that the capacity of the fuel bladder drops by about 1.
And if you fill the tank too full by squeezing too much more gas in after the pump clicks off the bladder can spit gas back out. About the carpool stickers, you send in your money and hope for the best although I've heard that the stickers are about gone, if not already all spoken for. These are very minor issues, taken in the context of an otherwise great car. Fuel bladders, common in airplanes and racing vehicles, are a rarity in commercial passenger cars, which typically use rigid tanks made of high-density plastic, said Craig Hoff, professor of mechanical engineering at Kettering University in Flint, Mich. Attempts to get Toyota to resolve the issue were unsuccessful, she said. The change is coming too late for Darlene Sharar, an engineering technician who lives in rural Washington and often drives in areas where gas stations are few and far between. The next time I filled the tank, it seemed to be working properly.
In the old design, rather than replacing the gasoline consumed with an equivalent volume of air, the bladder would shrink around the fuel. And the loss was substantial: Even the owner's manual warned that tank capacity could fall by as much as 1. This is a significant safety issue - we could have been killed. It was contained inside a metal shell for rigidity and protection from road hazards, so many owners never knew it was there. Now if we ask for a fill it will spit back some of the gas and some attendants are having trouble getting a seal to lock in the gas pump instead they have to hold the pump. Just don't over-fill the tank.
Toyota must be held accountable for this defect. There will be no warning before we run out of gas. When the next-generation hits dealer showrooms in late May, it will come with a bigger engine, better fuel economy and solar-powered cabin cooling. For a complete dissection of the gas tank and bladder from a 2004-2009 Prius, see the excellent , from which we have taken the liberty of borrowing the image below. The bladder which is inside the actual gas tank is flexible and temperature sensitive. A few weeks ago my partner went to get the car filled with gas and the attendant here in Oregon you aren't allowed to pump your own gas some how managed to overfill typically a fill is just over 10 gallons, this time it was just under 12! But as Toyota Prius owners in cold climates learned, the bladder also shrank in winter weather. Looked at the gas gauge and it still showed 2 bars.
