What kind of difference can the use biodiesel make when it comes to
changing the world for the better? Perhaps the biggest impact of the
use of biodiesel fuel instead of just plain diesel is on the human
health and the environment.
One of the biggest differences that biodiesel make is with regards to
smog. Using biodiesel actually reduces smog. Both unburned hydrocarbons
and nitrogen oxides in diesel fuel account for most of the particulates
in air pollution. When you use biodiesel product or homemade biodiesel
there is a substantial reduction of unburned hydrocarbons and if you
are using a blend that is right for your machine. Tests that have been
conducted according to EPA regulations have shown that the hydrocarbon
exhaust emissions that biodiesel are half that of that measured for
diesel fuel.
Can biodiesel make more energy? Unlike the burning of fossil fuels, the
burning biodiesel fuels actually gives back more energy to the
environment that it takes. Lifecycle studies of biodiesel production
show that for every unit of fossil energy it takes to manufacture ...

Fuel efficiency? Who wants fuel efficiency? Most people will never
thimk about fool efficiency.

The first demonstration Diesel engine built burned biodiesel -peanut
oil.

During the industrial revolution, the triple expansion steam engine
revolutionized steam power. Double the power or more for the same fuel.
Why do we not see triple or even double expansion internal combustion
gas generation engines, with efficient, fully combusted, cool exhaust,
filtered and deacidified?

If engines used water injected to increase the second fuel charge
expansion by steam generation, they would possibly contribute to
replacing the evaporative part of the ecological water cycle lost to
deforestation of paved areas. The exhausted water might well fizz,
containing some of the CO2 cast off in today's engines, so the water
might well concentrate acid if recycled. If this unavoidably corroded
engines, it could be cast off to decompose the ground nearby, entombing
the CO2 thought to be so harmful to the air. If the roadway contained
limestone, the acid would be neutralised, as it would if the engine's
water recycler contained consumable limestone / calcium sand.

The hot exhaust from the primary / combustion cylinder would go into
the expansion stroke of the larger secondary cylinder, and with water
injected into the hot gas turning to 1700 times the volume of water
vapor, and metered so that when the secondary exhaust valve opened, the
pressure drop cooling effect would condense the water, scavenging the
heat lost to single expansion engines and discharging cool, wet
exhaust. The water might be recyclable in a blown air cooled muffler /
condenser / filter. Such an engine would need no catalytic converter.
Close control and timing might well cushion the bottom of the secondary
expansion piston's cycle if the water vapor condensed just before
bottom dead centre and the opening of the secondary exhaust valve. The
secondary cylinder would have no compression phase, it's exhaust valve
open to allow the repositioning of the secondary piston to top dead
center and aspiration. The primary cylinder exhaust valve closes, hot
water is injected into the secondary exhaust cylinder, evaporates,
expands, and helps drive the secondary piston down. It may be that the
secondary cylinder needs no intake valve, relying only on the exhaust
valves of the primary and secondary cylinders for it's aspiration.

The secondary cylinder would be larger than the primary and the
expansion ratio would be different from the primary compression ratio,
being calibrated against timing and water expansion parameters. A
computer would control water injection.

"Modern" i.c. engines lose much of the fuel energy in hot exhaust and
water cooled blocks, let alone incompletely combusted CO gas. This
energy, if recovered, might save 50% or more of the energy lost, about
33% increase in efficiency.

I cannot see why the same principal would not work in a diesel ignition
engine.

Such an "internal steam engine" could reduce the consumption and price
of fuel. I guess that's why we haven't heard of it.

One difficulty is that an otto cycle (four stroke) only produces
exhaust every second revolution, so the secondary expansion cylinder
might want to be geared 1:2, or it's valve(s) timed to acommodate that
fact, or with an intermediate pressure vessel between the cylinders.
It's exhaust valve would close every second revolution, timed to the
exhaust of the primary exhaust stroke. A two stroke engine would not
need such complication, but it's secondary piston crank angle would be
offset so as to lengthen the primary power stroke to a full 1/2
revolution power / expansion stroke, as opposed to the common 1/4
revolution power stroke.

Another huge saving in fuel efficiency could be promoted at home, a
reversible air conditioner / heater might get used more to heat than to
cool over the course of a year, saving considerable heating fuel cost,
if mainly only during the spring and fall.. Why have we not heard of
it?

The only issue that I see for your idea is that the engine you propose

1500-2000 rpm. Yours would be happiest closer to 500 RPM.

Alternatively, If two four stroke cylinders were timed and valved so as
to feed only one secondary expansion cylinder which injected water to
expand and cool the exhaust gas, etc, then the power output stroke of
such a three cyliner engine would be 360 degrees in total as opposed
to two, one quarter revolution power strokes. Two such engines
connected together for balance and timed right might show very good
torque figures at near stall speed, like steam engines do. It would
also balance well.

Thank you for your assistance. I don't see why, really. See the
addendum above. It might work out, y'know.

Most cars never need all the potential power they lug around, and every
pound of engine and fuel saved, is a pound that does not sap the
delta-vee.

The second rat gets the cheese.

There is a free lunch, but not for everybody, and getting it ain't
easy. You got to sleep in, climb over the unhappy competition, and
study your method well if you want to continue successfully.

An internal steam engine could work.

Even if it was easy and efficient, you might have to fight the the
first rat as he weakens and dies to keep a grip on the rat trap and
it's bait.

The fuel supply problem will be beaten the day that a significant
number of people decide to drive mopeds or trikes to save gas. This
they will not do so long as they are likely to get rained on. Why not
an airbag outside the driver to keep the rain off and streamline the
vehicle?

A double expansion 5 HP internal combustion steam engine could charge
the batteries while you pedal or park, for that matter.

Why not recharge at home for an electric 50 Km range town trike you can
pedal home to plug in and charge for tomorrow, all for less than health
club membership and cabfare to and from the excercise machines and
drive through fast food joints? Ask the fatties why there is an energy
shortage. Ask the restraunteurs why they cannot satisfy them selves
with half price, half sized kids' servings on demand, even for adults?

You're talking about a version of the Still Engine, used in a few boats in
the 1920s. It claimed a small increase in thermal efficiency, but it never
went over for a variety of reasons. One was that a ship equipped with the
engine required two certified operating engineers -- one steam, one IC. g
The other was the considerable complexity involved.

There have been numerous other experiments in waste-heat recovery from IC
engines, at least one of which is in use today, in stationary cogeneration
engines. Some are equipped with an exhaust-stream turbine geared to the
output shaft, not unlike the turbines used in turbo-superchargers.

And I once saw an interesting engineering proposal for a diesel/Stirling.
Unbelievable, impractical, but ambitious complexity throughout.
