🔍 Key Concepts

• Study how starting air actually enters the cylinder through the cylinder head in a direct-start system. • Compare the function of a check valve versus a control (operated) valve in an air start line. • Note the relationship between the small pilot mechanism on the right (III) and the larger valve body at I.

💭 Think About

• Look at the flow arrows: does the part marked I admit high-pressure air directly into the cylinder, or does it only sense/control something? • Ask yourself which component in a starting system must be mounted in the cylinder head itself, and which ones are usually in manifolds or control blocks away from the cylinder. • Consider whether the element at I appears spring-loaded to prevent backflow only, or is it being positively opened by a spindle/rod from the pilot gear.

✅ Before You Answer

• Verify whether I is located in the cylinder head at the entry point of starting air to the combustion space. • Check if I has a moving valve spindle and seat that would open directly to the cylinder, distinguishing it from a remote control/reversing valve. • Confirm how the small valve at III sends air to operate the larger valve at I, and which of the answer choices fits that actuated-by-pilot-air role.
