1. The Diesel Cycle By Marcus Low

2. What is the difference? The Diesel engine takes in JUST air. The compression ratio is higher, thus higher efficiency. Diesel engines use direct fuel injection. No spark plug required.

3. Advantages & Disadvantages Advantages There is no KNOCKING in the diesel engine. Higher efficiency. Less expensive Disadvantages Pollution Heavy Initial high cost

4. Examples of vehicles that use diesel engines Cars Trucks Submarine Locomotives

5. Objective Definition of Diesel Cycle How the Diesel Cycle Works Examples of Diesel Engines Relevance of Diesel Engines Today

6. History & Definition 1892, Rudolf Diesel invented the Diesel Engine. Main goal- High Efficiency Definition- combustion process of a type of internal combustion engine in which the burning of fuel is triggered by heat generated in compressing fuel- air mixture

7. Internal View of Diesel Engine

8. Diesel Cycle Diagram

9. How it Works Comprises of 4 Stages: Intake: Inlet valve opens, exhaust closed. Compression: Both valves closed. Piston compresses air upwards. Fuel injected. Power: Fuel ignites. Gas forces piston downwards. Exhaust: Inlet valve closed. Exhaust valve opens. Piston travels upward.
