How To Make Hydrogen For Cars – Do Hydrogen Fuel Cells Increase Gas Mileage?

DEF is the abbreviation of Diesel Exhaust Fluid. It is a nontoxic organic compound which is composed of 67.5% DI water and 32.5% urea. It is utilized by an SCR System (Selective Catalytic converter) to convert smog producing nitrogen oxide into harmless water vapor and nitrogen. Vehicles have an on-board DEF storage tank that has the capacity of 16-30 gallons. In order to ensure smooth functioning of the SCR System, consistent refilling of storage tanks is an important requirement.

Never buy a car you haven’t driven. It is easier to inspect a car on level ground. That way you can tell if the car sits level. If the car you are inspecting is parked on uneven ground try to park it somewhere more level after you take it for a test drive.

Finally, check the inside of the exhaust pipe. Use your finger to rub around the inside of it. There should always be a tiny bit of something in there but if you rub around in it and your finger comes out black, unless it is a diesel, that’s not a good sign. It usually means it hasn’t been running right and is burning way too much petrol. If it is a diesel, then lots of black stuff is normal.

Drivability is not adversely affected. Interior noise level depends on the exhaust system you choose. Some will make it far louder; some will actually make it quieter. But most are just a little bit louder than stock. But the added dBs are also combined with a MUCH sweeter exhaust note, so it’s definitely worth it. And the interior of the Supra is pretty quiet anyway, so on the highway, it will be VERY livable. As far as low-end power goes, the down-pipe will greatly decrease Turbo Lag. So low-end power and response is much improved over stock.

Using an EBC is the safest way to raise boost, it will prevent spiking and over-boosting. But it really comes down to your budget. If you can afford an EBC, get one. If you can’t, go with a MBC. And always keep an eye on that boost gauge. And whatever you are using to control boost, remember to not get carried away, I don’t recommend going regularly over 18psi.

You will need to assess how much of the system needs to be replaced. This may mean replacing just one part of the system: the part manifold, the crossover piping, the scrap O2 sensor recycling, or the muffler. You may need to remove the whole system in order to replace the parts that have rusted out.

Of course there are other car repair diagnostic problems that can trigger the warning light to come on and you need to pay attention to how your car is operating to decide what the best course of action to take is. Does the warning light flash on and off depending on whether you are driving in the city or on the freeway? When the light is on, does the car drive differently?

You have to cut the tube on either sides of the converter. Use the reciprocating saw as well as the metal blades. Leave an allowance of 2 inches of tubing on the ends of the converter for the needed spacing. Allow the catalytic converter to fall by its own self but make sure you are not underneath it when it falls.
