Abstract
Abstract A water cooled internal combustion engine with a cooling blower arranged at one end face of the engine and with at least one water cooler which is acted upon by the cooling blower and extends alongside the engine. The internal combustion engine is supercharged and equipped with a supercharger intercooler arranged below the water cooler and parallel to the central axis of the engine. The cooling air delivered by the cooling blower passes through the supercharger intercooler in a direction perpendicularly with regard to the central axis of the engine. The supercharger intercooler has a gap of its own for the discharged air which has an exit parallel to the discharged air of the water cooler.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
104 words
A water cooled internal combustion engine having a central axis which includes in combination: a cooling blower arranged at one end face of said engine, at least one water cooler extending alongside said engine and operatively connected to said cooling blower to be actuated thereby, a supercharger air cooler arranged underneath said water cooler and in parallel alignment with the central axis of said engine, and means for directing the cooling air delivered by said cooling blower so that said cooling air flows through said supercharger air cooler and extending parallel to the path of the air to be discharged from said water cooler.
Claim 2
Dependent Claim
104 words
A water cooled internal combustion engine having a central axis which includes in combination: a cooling blower arranged at one end face of said engine, at least one water cooler extending alongside said engine and operatively connected to said cooling blower to be actuated thereby, a supercharger air cooler arranged underneath said water cooler and in parallel alignment with the central axis of said engine, and means for directing the cooling air delivered by said cooling blower so that said cooling air flows through said supercharger air cooler and extending parallel to the path of the air to be discharged from said water cooler.
Claim 3
Dependent Claim
83 words
A engine in combination according to claim 1, which includes cylinder rows in V-arrangement with one water cooler each over each of said cylinder rows, said water coolers defining a gap therebetween and being arranged for being passed through by air in vertical direction, said supercharger air coolers being arranged between said water coolers and said engine for being passed through by air in vertical direction, said supercharger air coolers also having discharge passage means leading into said gap between said water coolers.
