Sure,
compressed air is a clean

Like jet engines, ramjets mix and
compress incoming
air with
fuel, but they do so with a clever geometric design rather than with huge compressor blades.
Other R&D efforts in alternative forms of power focus on developing

compressed air.
For one, it does not completely eliminate the need for fossil
fuels, because the associated electric generators use natural gas to supplement the energy from the stored
compressed air.

compress the
air /
fuel mixture prior to combustion.
Adding GDI, or Gasoline Direct Injection, inside the cylinder rather than in the intake manifold as is now common, so - called Sequential multi-port
fuel injection, controls the
fuel even better for each particular cylinder, prevents
fuel puddling in the intake manifold, and allows the
fuel to cool the
compressed air in the cylinder.
In simple terms, the Atkinson cycle uses less energy to
compress fuel and
air together, and makes relatively more energy when that mixture explodes.
By keeping an intake valve open during part of the compression stroke, some of the volume of unburned
air /
fuel mixture in the cylinder moves back inside the intake manifold and lowers the volume being
compressed, or «pumped.»
Ignition: Or ignition timing is the precise point where the combustion process is initiated inside the
compressed charge of
fuel and
air.
Finally, the compression stroke closes the valves simultaneously,
compressing the
fuel and
air mixture until the spark plug ignites the mixture, beginning the entire process again.
SKYACTIV - X is the world's first commercial gasoline engine to use compression ignition, in which the
fuel -
air mixture ignites spontaneously when
compressed by the piston
The complete cycle of combustion begins — in this illustration — on the power stroke, when the spark plug ignites
compressed fuel and
air in the cylinder.
Instead, the piston
compresses the
fuel and
air mixture... Read More

compressed air, producing zero emissions.
One is a report on the Wheels blog by my friend Jim Motavalli about the possible rebirth of the «
air car,» a vehicle that runs on
compressed air and a small amount of
fuel to run a heater that boosts its range (it is said to get the equivalent of more than 100 miles per gallon when you account for the energy it takes to
compress the
air).
A far less costly option, although still a fossil -
fueled one, might be the as - yet - unreleased $ 6,800 Elio Motors vehicle, which is touted as being capable of getting 84 mpg, but there's another contender in the race to build clean affordable vehicles, and instead of being powered by electricity, the $ 10,000 AIRPod boasts of being a «Zero Pollution Vehicle» because it runs on
compressed air.
