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
