🔍 Key Concepts

• Main bearing loading in different types of reciprocating engines • How the direction of pressure on the piston (one side vs both sides) affects which part of the bearing carries the load • Difference between single-acting and double-acting engines

💭 Think About

• Think about which engine design has gas pressure acting on the piston in only one direction and how that makes the crankshaft press on one side of the main bearings most of the time. • Consider which type of engine could have the piston doing work on both strokes or on both sides of the piston, and how that would change where the bearing load goes. • Ask yourself: in which of these engine types would the crankshaft always be pushed in essentially the same direction, making the lower half of the main bearing carry the load continuously?

✅ Before You Answer

• Make sure you know the definition of a double-acting engine versus a single-acting engine. • Confirm for each choice where the gas pressure actually acts on the piston (one side only or both sides). • Verify which design causes a nearly constant downward radial force on the crankshaft journal into the lower half of the main bearing.
