oh yeah
everyone I know including myself has wanted to see a see-through diesel engine for a really
long time so after a lot of thought and planning I figured I would give it a try I've been
putting together a method to make this happen for over 2 years the only thing I was missing
was a company that made a single cylinder diesel engine to start the first episode that
is until my friend Alex told me that Kohler makes diesel engines I reached out to them
and it turns out that they were super nice people and without their involvement in this
series this probably would have never happened simply because it's already broken what a
single cylinder diesels that I found we're of poor build quality and I highly doubt they'll
be able to handle the amount of abuse that I'm planning on throwing at this engine it's
time to start this engine up for the first time and for the very first start I'm going
to pull start this one for the very first run and after that I'm going to use the electric
starter so let's see how this goes I haven't actually started one of these Kohler diesel
engines before let's see what happens
all right well that was a lot easier than I thought
it was going to be I mean 1 pull and the engine just started right up now that I ran this
engine for the first time which was a lot easier than I thought it was going to be and
you now know what engine I'm going to use to attempt to build the first see-through
diesel engine I'm going to move on with the contents of this episode get that Dyno from
the see-through engine bolt it on this engine Dyno this thing on regular diesel fuel get
a nice baseline and then I'm going to try something that I'm really curious about which
is the hydrodiesel the dyno is completely installed and I decided the dyno this engine
on three different fuels the first is going to be diesel the second is going to be biodiesel
and the third is going to be hydrodiesel which I am told Burns a lot cleaner than the other
two now that you know what fuels I'm going to be using it's time for the first Dyno run
which is going to be on diesel fuel I have my tachometer set up to measure the RPM an
exhaust gas temperature probe to measure the exhaust gas temperature an intake air temperature
sensor that way we're going to have a great comparison diesel fuel as a baseline then
biodiesel and hydrodieselapart from those sensors the one thing I'm doing different
this time as I'm using a thermal camera so before the first Dyno run I'm going to remove
some of these heat shields to allow the thermal camera to see the side of the cylinder wall
as well as this exhaust manifold here and that's going to give us a more accurate look
at just how much heat the engine is producing with each fuel I'm going to do three Dyno
tests where I just measure pure horsepower and torque I'm going to load the engine till
it gets to about 2800 RPM and leave it there for about 30 seconds to see how hot the engine
runs on each individual fuel to keep the results consistent before every Dyno run I'm going
to start the engine and run it for 5 minutes straight at full throttle and then at the
5-minute Mark I'm going to start the test
that was my 2800 RPM Target run on diesel
fuel let's take a look at those numbers
okay so that was a Dyno run on diesel next we're going to do the Dyno run on biodiesel
so that was the Dyno run on biodiesel now I'm going to put hydro diesel in the tank
bleed the lines so it's 100% hydro diesel and then my Dyno run on hydrodiesel
so that went pretty well overall hopefully I gave you some valuable information this
is quite a setup that we had to do here to measure what we measured here I thought it
was a pretty good comparison I know people are going to ask for some more solid results
but that was pretty good that being said I have another episode with this engine coming
up next and I'm not going to tell anybody what it is but it has something to do with
this turbo right here tell me what you think it's going to be in the comments below and
tell me what you thought about this video hopefully you enjoyed it and let me know if
you have any other tests ideas that you want to throw out there one of the things that
I was going to measure was the particulate coming out of the exhaust but I skip that
just because we have a lot of stuff going on already so that being said thanks for watching
tell me what you think in the comments below don't forget to subscribe and see you next time
what a mess definitely need a better container
