Description
Page - 1 -THE FIELD OF THIS INVENTION
This invention is in the class of air pollution control devices dealing with the problems of smog, this smog reducing device will deal with balancing of the amount of air to fuel ratios in an internal combustion engines when over fueling occurs, in order to reduce hydrocarbon emissions and increase the amount of energy developed from the combustion of fossil fuels BACKGROUND OF THE INVENTION
[001 ] Recently, internal combustion engine makers, particularly diesel engine manufacturers have been facing ever increasing regulatory requirements, in the field of exhaust emission regulations. Exhaust emissions take on a number of forms.
The present invention will address the visible form of black smoke coming out the exhaust pipe, which is comprised mainly of un-burnt hydrocarbons. To address these emission issues, different technologies have been developed, including the method of re-circulation of exhaust fumes (EGR). The most common method has been increasing the amount of air in the combustion chamber by turbo charging the intake manifold with compressed air coming from the turbo turbine interposed between the air cleaner and the intake manifold.

The present invention will address the visible form of black smoke coming out the exhaust pipe, which is comprised mainly of un-burnt hydrocarbons. To address these emission issues, different technologies have been developed, including the method of re-circulation of exhaust fumes (EGR). The most common method has been increasing the amount of air in the combustion chamber by turbo charging the intake manifold with compressed air coming from the turbo turbine interposed between the air cleaner and the intake manifold.
[002] It's a well known fact that a variation of oxygen and nitrogen enriched air forced into the intake manifold during the intake stroke will increase the energy output during combustion of fossil fuels and reduce hydrocarbon emissions, the cost efficiency of this process being in question.
Page - 2 -[003] The present invention is in the field of fuel to air ratio regulating apparatus and relates to a device capable of sensing the unbalance of fuel to air ratio being discharged into the atmosphere through the exhaust system of a combustion engine so that when an engine is under stress and is over fueling, the supply of air can be proportionately increased to compensate for the unbalance and lack of sufficient air coming through the normal turbocharged air supply system. This is accomplished by adding to the existing preset air to fuel ratios pressure engineered for each engine size by injecting into the intake manifold at specific intervals a high pressure puff of air, that is calibrated by the mechanism of the air pulsator valve, this will increase the amount of energy derived from the combustion o.f fossil fuels and at the same time reducing the amount of hydrocarbon emissions.
( 1) The present invention will address the over fueling problems of the internal combustion engine by injecting small amounts of compressed air into the intake manifold in a pulsating manner, the pulse of compressed air discharged into the intake manifold takes place at specific interval such as at the initial start of the fuel injection cycle and also will deliver successive pulses of compressed air injections when the engine is under severe stress, thereby compensating for the deficiency that comes with the predetermined set capacity of turbocharger turbines. These turbines are designed to deliver fixed quantities of air into th.e intake manifold always in accordance with the revolutions of the internal combustion engine and capable of supplying the correct fuel to air ratio of the stratified demands of the said combustion engine under normal conditions.
Page - 3 -( 2 ) One unquestionable objective of the present invention is the manner in which the compressed air is injected into the iyitake manifold when the engine is under stress, making it possible for the operator of the vehicle to supply at will several small puffs of air into the intake manifold rather than a continuous stream of high volumes of high pressure compressed air.
( 3 ) One definite objective of discharging a calibrated pulse of air into an already turbocharged air intake manifold is to prevent the total, disruption of the momentum and pressure of the turbine of the turbocharger already running at full capacity, where a continual supply of an alternate source of higher air pressure routed into the intake manifold could adversely affect the speed of the turbine.
( 4 ) Yet another aspect of the present invention is to monitor the fuel to air ratio of the engine exhaust system, by disposing into the exhaust system of the combustion engine a hydrocarbon analyzer transducer so that when the engine is under a continual demand for high torque and the fuel supply injected into the combustion chamber is increased and black smoke is coming out of the exhaust pipe, the hydrocarbon analyzer transducer will send a signal to the computer of the selector swatch on the pulsator valve and activate the air solenoid on. the servo in order to discharge a puff of air into the air intake manifold of the combustion engine, thereby compensating for the restrictions of air corning from the turbo charged air system, this will increasing the amount of energy produced from the combustion of fossil fuels and also reduce the hydrocarbon emissions.
