Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
In an internal combustion engine of the type having a cylinder, means for introducing fuel into the cylinder, and an electroexpansive member for actuating said fuel introducing means, improved apparatus for controlling said electroexpansive module in accordance with engine operation comprising means for charging the electroexpansive module in time ration to engine speed, and means responsive to the rotative position of the engine for discharging said module, said charging means and said discharging means being independently adjustable to afford adjustment of the timing and duration of fuel introduction into said cylinder, whereby quantity of fuel introduced to the engine as well as rate of introduction of fuel are regulated according to engine demands.
Claim 2
Dependent Claim
113 words
In an internal combustion engine of the type having a cylinder, means for introducing fuel into the cylinder, and an electroexpansive member for actuating said fuel introducing means, improved apparatus for controlling said electroexpansive module in accordance with engine operation comprising means for charging the electroexpansive module in time ration to engine speed, and means responsive to the rotative position of the engine for discharging said module, said charging means and said discharging means being independently adjustable to afford adjustment of the timing and duration of fuel introduction into said cylinder, whereby quantity of fuel introduced to the engine as well as rate of introduction of fuel are regulated according to engine demands.
Claim 3
Dependent Claim
51 words
Apparatus according to claim 1 wherein said charging means includes means for forming a voltage pulse and means for regulating the magnitude of the pulse generated by said pulse forming means, said regulating means being responsive to engine operation so that said module effects fuel introduction in response to engine operation.
Claim 4
Dependent Claim
48 words
Apparatus according to claim 1 including means for varying the functional relationship of at least one of said charging means and said discharging means in accordance with a variable of engine operation, such as engine r.p.m. engine intake manifold pressure, engine torque and constitution of engine exhaust emissions.
Claim 5
Dependent Claim
56 words
In an internal combustion engine as recited in claim 1 wherein said means for charging the electroexpansive module, means and said means for discharging the electroexpansive module each includes a serially connected transistor means and variable impedance means connected to said electroexpansive member for providing independent adjustment of the charging and discharging in said electroexpansive module.
