Normally, what does the lubrication process of a two-stroke engine consist of?
AThe oil deposited in the engine's crankcase is pumped into the lubrication circuit.
BThe oil is applied by suspension to the parts to be lubricated.Correct
CThis type of engine does not need a lubrication system.
Explanation
In two-stroke engines, lubrication is carried out by mixing oil directly with the fuel. As the mixture of air, fuel, and oil enters the engine, the oil remains suspended and deposits on the surfaces of moving parts, such as the piston and crankshaft, ensuring the necessary lubrication during operation. The alternative that refers to oil being pumped from the crankcase describes the typical operation of a four-stroke engine, which has an independent lubrication system. In turn, the statement that this engine does not need lubrication is incorrect, as all internal combustion engines require lubricant to prevent wear and seizing of moving parts.
