A heavier piston has greater inertia and will put more pressure on the crankshaft, causing it to rotate. So why not make this part from heavy metal - lead? The material, of course, is soft, but it is not a fact that it will melt when the fuel-air mixture ignites. All this requires testing in practice. The experiment is being carried out by enthusiasts from the Garage 54 channel. For the experiment, we took a heavy pig and melted it to obtain blanks for future pistons.
The next stage can be considered the most labor-intensive. This is turning parts from blanks on a lathe: the dimensions must be maintained with the required accuracy. When the piston is ready, it still needs to be brought to its “factory” state so that it looks like it did in the store. Before putting lead pistons into the engine, we weigh them. The standard part has a mass of 405 g, the “new” one – 2 kg 50 g. The difference, as you can see, is more than significant! We continue the experiment - install the rings in the grooves, attach the connecting rod and secure it all through the liners on the crankshaft. The most exciting moment is starting the engine. How will it behave, and will it even start? Watch the video!
