🔍 Key Concepts

• Two-stroke crosshead diesel engine construction – especially the roles of the piston, piston rod, crosshead, and crankcase • Function of a scraper box vs. scraper rings – where each is located and what each actually acts on • Oil control and contamination – how engines keep dirty oil and combustion products out of the crankcase

💭 Think About

• Think about where the piston rod scraper box is physically located and what surface it interacts with – is it touching the cylinder liner or the piston rod? • Ask yourself: what is the main risk if combustion residues and cylinder oil are allowed to run down along the piston rod toward the crankcase? • Compare the typical cause of side thrust and cylinder scoring: which parts and forces are involved, and would a scraper box on the piston rod realistically control that?

✅ Before You Answer

• Identify which part of the engine the scraper box is actually cleaning or protecting (cylinder wall vs. piston rod vs. something else). • Confirm whether oil scraper rings are on the piston or in the scraper box – are they alternatives or do they serve in different locations? • Decide which option best matches the goal of keeping crankcase oil clean in a crosshead engine, based on how the piston rod passes between the cylinder and crankcase.
