GASOLINE VS. DIESEL (FUEL CONSUMPTION 1950s Style)

- I have been wanting to make this video for a while now.
Hope you enjoy the comparison between gasoline and diesel gen sets.
The gas unit was built in October 1954, the diesel in February 1955.
It might also be worth mentioning, especially with generators, that diesel has a significantly longer shelf life than gas.
Nice video. Couple of crits:
diesels are the best, i used to repair diesel welder generators and 95% time the engine outlasts the gen units with over 10-20k hours
Dang you get the lucky finds I love these old engines even more of the diesel ones amazing video can't wait to see more
This is cool. Thanks for making it Mike.
Excellent video! The diesel wins due to its' high compression ratio (~20:1) and a full cylinder of air on the intake stroke. Compare that to the gasoline's low compression (~8.5:1) and a throttled intake stroke. The best comparison is when both engines are running at their max. torque, or highest efficiency, (highest volumetric efficiency), not highest speed, or not highest horsepower. Max. torque for the gasoline is when the cylinder is the most full during the intake stroke (~full throttle), and the compression pressure is the highest. If a gas engine could survive with a 20:1 ratio it would exceed the diesel in efficiency due to it's flame front speed. With today's direct injection gas engines, we can inject fuel quickly before igniting it, which eliminates pre-ignition knock, and allows us to raise the compression ratio a few points. Efficiency is now higher, (along with more NOx, so make sure that catalytic converter works well!)

Only you Mike can make watching two engines interesting. Thanks for taking the time to conduct the test!
Interesting Mike! BTW: I consumed 16oz. of Bud Ice watching your video, but deceived not to weigh myself! ...Newk from Kentucky
Hey Mike spectacular video what a way to spend the day I really enjoyed it thanks for taking the time to make your videos much better than television
This is a textbook example of a great science project for a kid!
That was surprisingly interesting Mike, thanks for taking the time to do the tests!
I really didn’t think I could find somebody even more interested in old generators/equipment as me and now I did! Love your channel it should definitely get more recognition for the quality and outstanding knowledge you possess! Now time to catch up on all of your videos lol
Thank you for making this video mike! I enjoyed watching and seeing the results
These 65 year old machines look like they will easily outlast any of those chinese gensets you can buy at the hardware store
I'm a retired mechanical engineer who worked for over 40 years in gas turbine engine manufacturing and testing. This exercise was extremely well thought out and executed. Well done!
I did not find it dry. It was very enlightening. Thank you for your time and effort.
Very cool video :) I can't say that I have ever seen someone do a comparison between the two, so I found it quite interesting :)
I admire your work and efforts to make some sense of this issue. Thank you.
I enjoyed it a lot. Thanks! It was a lot of work to do.
