1. The Diesel Cycle By: Andrew Hoover Objectives: 1)Explain the Diesel Cycle 2)Relate it to basic examples 3)Is our engine a diesel cycle?

2. What is the Diesel Cycle? The Four Stages of a Diesel Cycle: Adiabatic Compression Adiabatic Expansion Isobaric Exhaustion Isobaric Intake http://auto.howstuffworks.com/diesel-two-stroke1.htm

3. Examples Volkswagen TDI Engine – new air intake values and direct injection fuel Trains and other Large Power Vehicles – use a diesel two stroke engine for maximum power Majority of cars and smaller diesel engines are usually four stroke

4. Is Our Engine a Diesel Cycle? The engine we are looking at is not diesel Has a spark plug to ignite air-fuel mixture Does not directly inject the fuel into the cylinder

5. Ultimately, The diesel cycle uses diesel through a four-stage cycle with direct injection and no spark plug to create power Any diesel powered vehicle or engine is an example of the diesel cycle Our engine is not an example of a diesel cycle due to the spark plug involved in igniting the air- fuel mixture
