How Fuel Efficiency & Consumption Works - Scrap Mechanic Science!

How does fuel consumption in Scrap Mechanic work? With the help of SCIENCE, I'm going to find out which engine is the most efficient!

How efficient are scrap gas engines?
Does the number of bearings make a difference?
Does the power level make a difference?
What does upgrading engines do?
Gas vs electric engine showdown!
Are thrusters really that bad?
Which engine is the most efficient?

I've always been curious about how fuel efficiency works in Scrap Mechanic Survival. Do you really need a fuelless car? Or can a good ol' gas engine at level 5 do the job? Are batteries more efficient? Today, I found out.

Did you enjoy this video? Do you want to see more Scrap Mechanic Science? Or perhaps science in a different game? I'd love to hear your thoughts.

the electric engine may seem more fuel efficient at first glance

but remember that in scrap mechanic, gas is more renewable than electricity for some reason
there's no solar panels or wind turbines, but there's literally entire ponds full of oil if you know where to look for them

I also used to do some Experiments for building Flyers. Some of the most interesting Results I got that you could maybe verify are:

-Actual block weight doesn’t scale linearly with the weight description. The relation is:
1 – 1; 2 – 2; 3 – 3; 4 – 4; 5 – 6; 6 – 8; 7 – 10; 8 – 14; 9 – 18
Notable exceptions are Small Pipes each weighing 1.5 per Block as well as bearings, pistons and springs which have no weight.

-Thruster Force is proportional with Thruster fuel consumption for a give Level. Force increases exponentially for each setting with a base of 1.5

-Thruster Force varies slightly over time, in magnitude and direction. The Game files also hint at this.

-Free bearings don’t have friction.

-Air resistance is proportional to mass and velocity, rather than real air resistance which is proportional to the drag coefficient and velocity squared in most common cases.

-Bearing are much weaker in survival than in creative mode. When met with a linear force they move or stretch a lot.

How do you have 230 Subs... I thought you had at least 6 or 7k Subscrivers, this is underrated content.. you deserve more subscribers, keep this up!

[Germinight]

That is some amazing experimenting you did there. I really like how these results turned out. Sucks that the thrusters are so inefficient though. Amazing job Dr Pixel. The "Dr" part of your name really fit well in this video

[trollvincent]

My god this whole channel is so underated ! I loved it ! Thanks !

[Dr-Pixel]

Somebody looked at the game code and came to the following conclusions:
1. Efficiency scales exactly as I assumed
2. Batteries and gasoline don't seem to have a difference, so the electric engine and gas engine should be equally efficient
3. Past a certain point, fuel consumption doesn't increase linearly with weight, but with a square root.

Thanks for "wasting" your time to save me from wasting my time! I wish you many subscribers and 2 pancakes :)

[tematist]

I like your humour, science and montage. You are the best)

[_miobrot_]

All I can say is that I wish I found this channel a year earlier from now. Legendary content!

My doctor: Long haired thruster doesn't exist, it can't hurt you.
Long haired thruster: 11:29

[machineball]

the force of a thruster goes up exponentially, I assume that its efficiency would to
measuring the thrust produced in the equivalent of weight force of the concrete block 3
L1 - 6.4
L2 - 9.5
L3 - 14
L4 - 21.3
L5 - 32.02
L6 - 47.6
L7 - 71.2
Keep in mind that the units shown are of the force in equivalent to a number of concrete block 3
the mass of the concrete block 3 is 35.5625
also the mass of the thruster goes down when you upgrade is so the thrust to weight ratio will change.
you should also note that the torque of the gass engine follows a similar path as wall as the rpm of the electric engine.
I recommend making a dynamotor in a controlled environment. its not that hard. I've ben studying the game's physics engine and I've ben working on a 'cyclotron' of sorts to study the aerodynamic drag or general resistance as I call it and how it scales.
im hoping to get a video out covering my findings soon.

there are lots of creative people in the community witch is good but it hurts me to see innovative people getting swept under the rug and how over saturated the game is with nonsense.

[Vajdani]

Damn, I enjoyed this video a lot more than I thought I will

[inund]

Protip: if you did this with saw blades, you wouldn't have to worry about bots getting in the way

[johnraven]

Thanks for the info, I can now make more efficient cars

[malindukumaradasa]

The way you carried out the experiments was so interesting to watch

[Gaff]

That compare electric to gas engine was very cool. Thrusters to engines was like compare bananas to feathers... But still didn't know upgrade thrusters decreases it's weight.

[KaneyoriHK]

The normal like, consensus or design is that electric engines have better torque, they are better for moving something heavier than a gas engine, which provides speed, that is the main difference between the two, they are about equal in efficiency according to the data, but if you want to go fast, strap a gas engine on there, if you want power, strap an electric engine on there, this is how they were created, with these two functions in mind. Of course this logic isn't perfect, at times the speed counteracts the torque problem, but from what I've seen, this is how they work.

[prebenkul]

so if you had 2 lvl 5 engines connected to 2 wheels each, would that be more efficient in fuel than having 1 engine lvl 5 connected to 4?

[glil]

What editing software do you use? Thanks for your answer

[Mateo-ziub]

You forgot the mountable spungun. Instead of fuel uses potatoes, but it´s like a thruster.
