🔍 Key Concepts

• Requirements for crankcase explosion relief valves on large diesel engines (bore greater than a certain size) • How many separate crankcase sections/compartments exist on an in-line engine compared with the number of cylinders • Rules that set a maximum spacing between relief valves along the crankcase and a minimum number per engine

💭 Think About

• First, decide whether a 13 inch bore engine falls above or below the common regulatory threshold for requiring crankcase relief valves. How does that affect how many are needed? • Think about whether each cylinder needs its own valve, or whether one valve can protect more than one crank throw/compartment along the crankcase. • Consider if the rules specify both a minimum number of valves per engine and a maximum distance (or number of crank throws) that a single valve can cover.

✅ Before You Answer

• Confirm whether an engine with a 13 inch bore must be fitted with crankcase relief valves under applicable rules/class requirements. • Check if the rules state a minimum of two valves per engine, regardless of size, once the bore/volume threshold is exceeded. • Verify whether one relief valve can protect more than one cylinder/crank throw, and how that affects the total number needed on an eight‑cylinder in‑line engine.
