Patent ID: 7591255

Claim:
Internal combustion engine comprising: an intake manifold to receive and collect gas to be burnt in an engine cylinder and an exhaust manifold to collect and output exhaust gas from the engine cylinder, a first turbocharger to compress air to allow more air to fill the engine cylinder, the turbocharger including a first turbine that transforms exhaust gas flow into mechanical energy to actuate an air-compressor, the first turbine having a turbine inlet fluidly connected to the exhaust manifold to receive exhaust gas that operates the first turbine and a turbine outlet to output the exhaust gas used to operate the first turbine, and an EGR (Exhaust Gas Recirculation) device to recirculate exhaust gas, the EGR device comprising an EGR heat exchanger having: an exchanger inlet fluidly connected to the exhaust manifold through an EGR valve to receive warm EGR gas, an exchanger outlet fluidly connected to the intake manifold to output cooled EGR gas, a cooling medium inlet to receive a coolant, and a cooling medium outlet to output the coolant once it has been used to cool the EGR gas wherein the cooling medium inlet is fluidly connected to the turbine outlet so as to use the exhaust gas outputted by the turbine as the coolant.
