Rapid exhaust catalyst heating using a glow plug

A system for reducing internal combustion engine emissions, comprising:

• an internal combustion engine comprising:
• at least one combustion chamber;
• and
• an engine fuel supply fluidly connected to the at least one combustion chamber;
• a catalytic converter fluidly connected to the at least one combustion chamber via an exhaust line;
• a glow plug positioned along the exhaust line between the catalytic converter and the combustion chamber;
• and
• a flame accelerator positioned along the exhaust line downstream of the glow plug and upstream of the catalytic converter;
• wherein the flame accelerator has a matrix of metal for generating additional turbulence;
• wherein the exhaust line does not have a fluid connection to a fuel supply separate from the engine fuel supply connected to the at least one combustion chamber.
