Why hasn't anyone tried making a combustion engine using fusion? (lemmy.ml)

I searched for the engine briefly, and found no mention of anyone thinking of this.

This post comes from this comment of mine.

In my original comment, I note that I immediately think the strain would blow the entire thing a part.

What are your reasons of why you think would not work, or why no one has tried, or maybe you know someone who did try?

Note, Not the size of a car. More like the size of a cargo ships diesel engine. ("Wärtsilä-Sulzer RTA96-C" as an example)

Imagined design. Original Post

There is one variant called Magnetized Target Fusion that kinda-sorta works like this, where the "cylinders" are made of liquid Lithium. On each "stroke" of the engine:

A rotating chamber of liquid Lithium is spun to make a cylinder of liquid metal
500 pistons situated at the site of each spinning Li pool are precisely synchronized to push the liquid metal inward, turning it into a sphere
Fusion fuel (H plasma) is injected into the middle
The intense pressure forces the fuel to undergo fusion, pushing the pistons back out and distorting the Lithium back into a cylinder
