🔍 Key Concepts

• Look at the components labeled A, E, and G and think about what type of energy they store or move (liquid, air, electricity, or combustion gas). • Notice the colored lines showing the working medium in the system – ask whether they represent fluid under pressure, compressed air, electrical wiring, or exhaust/charge gas. • Consider common diesel starting methods: electric starter motors, air-start systems, hydraulic starters, and small gasoline/diesel pony engines – match the drawing to one of these.

💭 Think About

• Does the component at A look more like a fluid reservoir, an air bottle, a battery, or a fuel tank? How does that influence which type of system this is? • The long cylinder at E with lines going in and out – is it acting like an air bottle, an accumulator storing pressurized fluid, or a fuel tank? • If this were an electric or gas-engine start system, what key parts (like spark plugs, batteries, alternators, flywheels, or air-start valves into the cylinders) would you expect to see that are missing here?

✅ Before You Answer

• Decide what medium the system uses: Is it liquid under pressure, compressed air, electrical power, or combustion gas? • Identify whether E is functioning as an accumulator/pressure vessel, a battery, or a fuel tank based on its connections and the presence of lines rather than cables. • Verify that the system uses pressure lines, valves, and a reservoir/accumulator rather than electrical components or a separate small engine.
