how is this engine lubricated?
In 2-stroke crankcase scavenged engines, the interior of the crankcase, and therefore the crankshaft, connecting rod and bottom of the pistons are sprayed by the 2-stroke oil in the air-fuel-oil mixture which is then burned along with the fuel.

what is the estimate time of the formation and evolution of the solar system? It began 4.5 billion years ago is there any proof or model which justifies its formation? Yes, it's called the nebular hypothesis who gave this hypothesis? Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace what was stated in it, can you give at least one point? It says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud. what do you mean by this last term of cloud? It is a type of interstellar cloud, the density and size of which permit the formation of molecules, which unexpected chemicals are found in the other type of cloud you mentioned just now? Formaldehyde, methanol, and vinyl alcohol. is the first one used in photography? Yes, in photography, formaldehyde is used in low concentrations for process stabilizer in the final wash step. where else is it used? In drug testing, as an antiperspirant. is the second one toxic? Methanol is toxic and it is used for what? It is used to fuel internal combustion engines.

Internal combustion engine [SEP] Lubrication
Surfaces in contact and relative motion to other surfaces require lubrication to reduce wear, noise and increase efficiency by reducing the power wasting in overcoming friction, or to make the mechanism work at all. Also, the lubricant used can reduce excess heat and provide additional cooling to components. At the very least, an engine requires lubrication in the following parts: In 2-stroke crankcase scavenged engines, the interior of the crankcase, and therefore the crankshaft, connecting rod and bottom of the pistons are sprayed by the 2-stroke oil in the air-fuel-oil mixture which is then burned along with the fuel. The valve train may be contained in a compartment flooded with lubricant so that no oil pump is required.
