It is been a little bit due to the fact we previous checked on the wacky mad experts over at Garage 54. Recently, the crew has been playing all around with plastic elements, building a established of plastic pistons. Do plastic pistons even perform? Let us locate out!
Like quite a few automobiles on the Garage 54 shop floor, the very poor Volga check matter been given a beating so undesirable that the motor essential to be torn down. Our host Vlad figures that they may well as effectively carry out an experiment. The group once manufactured wood pistons, and they didn’t operate out so very well. In real Garage 54 manner, the men are returning to the notion of creating pistons out of an choice material and made the decision to make them out of hard plastic.
The motor is not far too worn, regardless of all of the abuse that this car or truck has suffered in different experiments. Only a single piston has some problems from overheating.
Vlad mulls about which plastic to use prior to settling on a Caprolon Polyamide polymer. This things is typically employed to make bushings and gears a piston is a little bit outside the house of the scope of this product.
The idea of earning motor parts out of plastic isn’t new. Car Journal reported that Matty Holtzberg was making plastic engine pieces all the way again in the 1970s. Holtzberg manufactured plastic pistons and even experimented with engines mainly of plastic. It’s going to be intriguing to see Garage 54’s endeavor at the identical notion.
The crew fabricated some plastic pistons from good stock. The approach of making these is amazing to observe.
The staff suits the plastic pistons into the motor and offers it a whirl.
The motor not only commenced, it also ran with the plastic pistons for rather a bit of time. The motor eventually gets very hot ample that the pistons grow and get stuck, in essence seizing the engine. Vlad figures the greatest solution is to wait around for matters to amazing down.
Vlad returned to the scene the subsequent working day and somehow got the car to start yet again. This time, the motor experienced a more durable time starting, and it sooner or later smoked out the shop prior to it stopped managing.
The staff let the engine awesome down again just before providing it a third, fourth — and eventually fifth — go. The engine receives more challenging to get started every time and smokes up the garage with fumes from the burning plastic. At some place the engine stops operating solely, and the staff finds out that two cylinders are not building any compression at all. To make issues worse, one of the spark plugs has key damage from impression with a piston.
A teardown reveals that the plastic pistons sustained some heavy destruction.
But I’m actually astonished that they are not a lot more destroyed. Vlad figured out that the pistons weren’t so significantly burning as they were deforming. 1 of the pistons deformed so poorly that the piston rings began disintegrating. That cylinder was the 1 destroying its spark plug.
Frankly, it’s quite amazing that the car even started, allow on your own ran a complete 5 instances.
When the experiment was a smashing achievement, I wouldn’t suggest earning your car or truck operate on plastic pistons. Your trip will seize seemingly the minute the engine gets scorching.
