Question 1 of 27070

Which of the following fuel systems is characterized by a complete absence of high pressure fuel lines?

🔍 Key Concepts

• High-pressure fuel lines vs. no external lines in different diesel fuel systems • How unit injectors and similar systems combine pump and injector functions • Basic layout of common rail, rotary, and in-line fuel systems on marine diesel engines

💭 Think About

• For each option, picture where the fuel is pressurized and how it gets to the injector nozzle • Ask yourself: Does this system use a shared high-pressure pipe (rail or line) feeding several injectors, or is pressure generated right at each cylinder? • Think about which systems are known for having multiple injectors all supplied from a single pressurized source

✅ Before You Answer

• Identify which systems definitely use one or more high‑pressure lines running from a pump to injectors • Identify which system, if any, has the pumping and injection functions combined at each cylinder, eliminating the need for separate high‑pressure lines • Before choosing, rule out any option you know has a common distribution line or multiple delivery lines under high pressure
