Title: Fuel injected internal combustion engine pollutant control system

Patent ·
OSTI ID:5803935

A fuel injected internal combustion engine is described comprising: an air intake apparatus having at least one resistance heating element capable of heating air passing therethrough to a temperature within a range of 160/sup 0/F to 180/sup 0/F, and an air temperature sensing means situated downstream of the resistance heating element to control the temperature of the heating element; combustion chamber means including a primary combustion chamber and a contiguous pre-combustion chamber wherein a sparkplug is situated. The combustion chamber means further include a primary intake port to the primary combustion chamber and an auxiliary intake port to the pre-combustion chamber, as well as an exhaust port to the primary combustion chamber, wherein passage of air/fuel or exhaust through the ports is controlled by the selective positioning of a valve respectively positioned adjacent each port; air intake manifold means for directing air from the air intake apparatus to the combustion chamber means; a free-wheeling fan situated within the air intake apparatus to increase the turbulence of the air drawn through the air intake manifold means, whereby mixing of the air and fuel is enhanced to improve combustion within the combustion chamber means; a fuel pump; fuel injector means for directing fuel received from the fuel pump to the air intake manifold means for mixing with air prior to being drawn into the combustion chamber means; a flow constricting valve in the proximity of the fuel injector means inlet, to help vaporize and increase turbulence of the fuel as it enters the fuel heating reservoir; and means for injecting a menthanol/water vapor mixture into the air intake manifold means.
