Diesel Cycle

Facts:

Key operating facts:

• Power control
  • More air $\Rightarrow$ More power
• Fuel Injection
  • End of compression stroke

Combustion:

• Air/fuel ratio not constant
  • From overall lean to very lean
• Non-premixed
  • Start of combustion controlled by fuel injection

Pros/Cons:

• Higher compression ratio $\Rightarrow$ higher efficiency
• Higher emissions due to non-homogeneous mixtures
