Toyota's Innovative Combustion Control Device for Internal Combustion Engines

Strategic Insights -

Toyota has developed an innovative combustion control device for internal combustion engines, which enables the simultaneous performance of premixed combustion and diffusion combustion within the combustion chamber. This device separates the combustion process into two distinct phases, allowing the engine to take advantage of the benefits of both premixed and diffusion combustion while minimizing emissions and stabilizing combustion, even in transitional operation and when using low cetane number fuel.

Key Takeaways:

  • The combustion control device separates premixed and diffusion combustion within the combustion chamber by controlling the heat generation ratio or the interval between fuel injections.
  • This separation enables the advantages of both premixed and diffusion combustion to be utilized, reducing the delay of ignition for preceding premixed combustion and its impact on succeeding diffusion combustion.
  • The device is designed to reduce emissions and stabilize combustion, even in transitional operation and when using low cetane number fuel.
  • The configuration allows for the utilization of both premixed and diffusion combustion, enabling a more efficient and environmentally friendly operation.
  • The device was patented under Application No. WO/2011/118031 and PCT/JP2010/055399.
  • Mitsuhiro Nada and Toyota Jidosha Kabushiki Kaisha are the named inventors and applicants.

Statistics:

  • The patent was published on September 29.
  • The patent was filed on March 26, 2010.
  • The device separates premixed and diffusion combustion within the combustion chamber.
  • The configuration enables a reduction in emissions and stabilization of combustion.
