Supercharged internal combustion engine equipped with an air intercooling system
First Claim
1. A cooling system for an internal combustion engine of the type having a low volumetric compression ratio and highly supercharged by at least one turbocompressor so as to have a high mean effective pressure rating, said cooling system comprising a forced ventilation cooling system including at least one liquid radiator, at least one air radiator, and at least one device arranged to generate an air-flow through the two radiators and comprising pressure generating means cooperating with at least one sheathing which channels the air through said radiators, said two radiators and said pressure generating means being arranged in series, with respect to the air-flow, and wherein the liquid radiator is adapted to be part of a closed circuit for the internal liquid cooling of the engine whilst the air radiator is adapted to form part of a direct cooling circuit for the supercharging air delivered by the turbocompressor, said liquid radiator being arranged upstream of the air radiator in the abovesaid air-flow, said sheathing comprising a first duct which channels a first part of the total air-flow onto the whole of the liquid radiator, then onto a part of the air radiator, and a second duct which channels the complementary portion of the total air-flow directly onto the remaining part of the air radiator, situated close to the supercharging air outlet of said air radiator.

Abstract
A highly supercharged engine with a high mean effective pressure (m.e.p.) is equippped with a cooling system including a radiator for the liquid cooling of the engine and a radiator for the supercharging air delivered by a turbocompressor. The liquid radiator is positioned upstream of the air radiator in the air-flow generated by a common blower.
