Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
An intercooler for a vehicle engine incorporating an exhaust gas turbocharger and an air conditioning system, said intercooler comprising: a charge air cooler loop employing a glycol-water coolant and including a low temperature reservoir, said charge air cooler loop operatively connected to cool heated, pressurized air from said turbocharger before it flows into said vehicle engine; and an air conditioning system bypass loop operatively connecting said air conditioning system to said charge air cooler loop; where said charge air cooler loop and said air conditioning system bypass loop are configured so that said air conditioning system bypass loop operates during vehicle braking to cool said glycol-water coolant to charge said low temperature reservoir.
Claim 2
Dependent Claim
113 words
An intercooler for a vehicle engine incorporating an exhaust gas turbocharger and an air conditioning system, said intercooler comprising: a charge air cooler loop employing a glycol-water coolant and including a low temperature reservoir, said charge air cooler loop operatively connected to cool heated, pressurized air from said turbocharger before it flows into said vehicle engine; and an air conditioning system bypass loop operatively connecting said air conditioning system to said charge air cooler loop; where said charge air cooler loop and said air conditioning system bypass loop are configured so that said air conditioning system bypass loop operates during vehicle braking to cool said glycol-water coolant to charge said low temperature reservoir.
Claim 3
Dependent Claim
111 words
An intercooler for a vehicle engine incorporating a supercharger and an air conditioning system, said intercooler comprising: a charge air cooler loop employing a glycol-water coolant and including a low temperature reservoir, said charge air cooler loop operatively connected to cool heated, pressurized air from said supercharger before it flows into said vehicle engine; and an air conditioning system bypass loop operatively connecting said air conditioning system to said charge air cooler loop; where said charge air cooler loop and said air conditioning system bypass loop are configured so that said air conditioning system bypass loop operates during vehicle braking to cool said glycol-water coolant to charge said low temperature reservoir.
Claim 4
Dependent Claim
111 words
An intercooler for a vehicle engine incorporating a supercharger and an air conditioning system, said intercooler comprising: a charge air cooler loop employing a glycol-water coolant and including a low temperature reservoir, said charge air cooler loop operatively connected to cool heated, pressurized air from said supercharger before it flows into said vehicle engine; and an air conditioning system bypass loop operatively connecting said air conditioning system to said charge air cooler loop; where said charge air cooler loop and said air conditioning system bypass loop are configured so that said air conditioning system bypass loop operates during vehicle braking to cool said glycol-water coolant to charge said low temperature reservoir.
Claim 5
Dependent Claim
105 words
An intercooler for a naturally aspirated vehicle engine incorporating a manifold and an air conditioning system, said intercooler comprising: a charge air cooler loop employing a glycol-water coolant and including a low temperature reservoir, said charge air cooler loop operatively connected to cool air flowing into said manifold; and an air conditioning system bypass loop operatively connecting said air conditioning system to said charge air cooler loop; where said charge air cooler low and said air conditioning system bypass loop are configured so that said air conditioning system bypass loop operates during vehicle braking to cool said glycol-water coolant to charge said low temperature reservoir.
