Diesel Engine Model 31009 Working Principle Physics Experiment Internal Combustion Engine Test Tool
A part of the review has been auto-translated.
The product was improperly handled during transport. Not really protected, there is a cardboard surrounded by a plastic pocket. When I saw the box, I had a doubt as to the state of the product. And indeed, the platinum is cracked.
O produto é extremamente simples, e parece ter sido pintado à mão. Mas atende a finalidade.

I liked it so much.
Lærerikt. Denne bruker jeg for og lære barnebarna mine hvordan en dieselmotor virker.
For the price it is not too bad. The down sides are the lack of restraint on the shafts from moving left to right. This means the "points" that run the lights bend and do not conduct as they go around. Also on my model, the cog for the big end to the cam shaft was moulded weird, the result being an elliptical motion that only just gripped the larger cam shaft gear during the cycle. Again, the valves do not seat in the holes cut for them. Will it be useful for teaching? Yes Is it high quality? No And my box was battered quite badly on delivery, it was quite flimsy.
