Diesel Vs Gasoline Vehicles

Hydrogen Boosted Gas Engines

With the ever increasing cost of gasoline prices,

auto makers are having to work overtime to cost

effictively improve the fuel economy, while still

meeting the strict emission requirements of today

with gasoline engines.

One ideal and promising way to boost the fuel

economy of gas engines is to add hydrogen to the

fuel/air mixture in the engine. Since hydrogen

isn’t available at the local gas station, selling

a hydrogen boosted gas engine wasn’t on the list

of engines – until now.

Lack of emission

A major cost and environmental advantage to hydrogen

boosted gas engines are low amounts of NOx emission

gas, which will completely eliminate the need for

external NOx emissions control. Currently, NOx

emissions control is a major cost problem for diesel

engines which use expensive traps to meet the

emission standards. Diesel engines particulate

emissions that must be collected by a filter that

should be changed periodically.

Hydrogen boosted engines on the other hand require

neither NOx or particulate control and require only

a low cost oxidation catalyst to control very small

amounts of exhaust which is formed mostly during

the engine starting up and warming up. Additional

cuts in emissions control requirements stem from

the engine’s ability to use only the clean hydrogen

enriched charge during the cold start phase when

90% of emissions are generated in the emission test.


The hydrogen boost system is effectively a bolt

on technology that can be added to an existing

vehicle’s engine compartment. According to those

developing the system, the cost of the system is

less than half of the added cost for diesel.

The future

Prototype hydrogen boosted engines are now be

installed in test SUV vehicles that have

sufficient space for the reformer and it’s related

system. The start of long term road testing

for performance, reliability, and durability

information is planned for later on in the year

before the system goes further into development.

Four cylinder gasoline engines will likely be the

prime candidates for the technology as high gas

prices continue to generate competition among the

higher fuel economy models that seek MPG


With gas prices getting higher and higher, hydrogen

boosted gas engines offer you the chance to get

more miles per gallon and not have to worry about

burning up all of your fuel. Instead of having to

go out and buy a diesel to conserve fuel, hydrogen

boosted units will help you preserve gas.

Even though they aren’t available to buy right now,

they will be very soon. Many manufacturers are

looking into them, as they offer gasoline engines

something like never before. If you own a gas

powered vehicle and have thought of giving it up

to go diesel, you might want to think again – as

hydrogen boost units may change the world of gas

engines forever.
