Could Hydrogen Improved Gas Engines Power Cars In The Future?
Car manufacturers are working nonstop looking for ways to have their cars run more efficiently due to the constant concern over high gas prices. Meanwhile, they can't neglect tough emission standards that are presently in place for gasoline engines. There is a promising way to boost the mileage of fuel for gas engines, and that is by adding hydrogen to the fuel/air mixture.
Prior to this, no hydrogen boosted engine has existed because hydrogen is not currently available at fueling stations. Since adding hydrogen could be the ideal way for better fuel performance, that may soon be changing. Hydrogen boosted gas engines work effectively due to small proportions of NOX emission gas. For that reason, requirements for controlling external NOX emissions could potentially possibly be done away with. Diesel engines incur significant expenses with NOX emissions control as they must utilize high cost traps to satisfy emissions standards. Diesel engines release particulate pollutants which are gathered with a filter that requires regular replacement.
The advantage to using a hydrogen boosted engine is the fact that it won't require NOX or particulate control. To manage the limited particles of exhaust that are created during the vehicle's warm up time simply requires an inexpensive oxidation catalyst. The engine has the ability to use only the clean hydrogen enriched charge when starting up cold, and this is when almost all of the emissions are generated during an emissions test, and that is why additional cuts can be made in emissions control requirements.
This newest technology makes it possible for a reformer to be included with a pre-existing engine compartment which, in effect, provides the car with a hydrogen boost system. According to system developers, this is even less expensive than adding diesel. Because of their ample space for a reformer and its related system, sport utility vehicles are serving as testing grounds for prototype hydrogen boosted engines. It's going to be some time before the system is able to be developed more as additional testing needs to be done in the areas of performance, durability, and reliability. This technology will likely be targeted toward four-cylinder gasoline engines. Economy auto producers who hope to be at the forefront with the best fuel efficiency will have to compete hard in order to succeed.
Hydrogen enhanced fuel engines are a means to get reduced fuel bills, even with the rising prices at the pumps, because of getting a lot more miles per gallon. You'll have the option to save on gas with a hydrogen boosted unit, instead of having to go out and buy a diesel vehicle. The hydrogen boost system may very well be one of the long-term answers for the energy issues we have in this world.
