Combustion air for use in an engine is normally compressed by a compressor which adds heat during the process of increasing the density of the combustion air. To decrease the heat content of the combustion air, an aftercooler is used. When compressing combustion air to a higher density, the combustion air is compressed by a first compressor section to a first preestablished pressure and temperature and by a second compressor section to a second preestablished pressure and temperature. To decrease the heat content of the highly compressed dense combustion air, a first aftercooler having an air to liquid configuration is used and a second aftercooler having an air to air configuration is used.
A method of cooling combustion air for use with an engine, said engine having a block at least one cylinder bore being positioned in said block and having a piston assembly operatively positioned therein, a plurality of cooling passages position in the block, an intake manifold and an exhaust manifold;
A combustion air cooling system being used with an engine, said engine having a block including a plurality of cooling passages, at least a cylinder bore having a flow of combustion fluid and a flow of combustible fluid being supplied thereto, said combustion fluid and said combustible fluid combusting and forming an exhaust;
An engine has a block having at least one cylinder bore in which is operatively positioned a piston assembly, a plurality of cooling passages within said block, an intake manifold being in communication with said at least one cylinder bore by an intake valve mechanism, an exhaust manifold being in communication with said at least one cylinder bore by an exhaust valve mechanism and a cooling system having a heat exchanger being of a liquid-to-air type configuration being connected to said engine, said cooling system having a liquid coolant pump being driven by said engine and circulating a flow of liquid coolant within said plurality of cooling passages and said heat exchanger;
A combustion air cooling system for use with an engine, said engine has an exhaust manifold and an intake manifold, at least one cylinder bore having a piston assembly therein being movable between a top dead center position (TDC) and a bottom dead center position (BDC), at least one intake valve mechanism being movable between an open position and a closed position during operation of said engine, a flow of combustion air being communicated between said intake manifold an said at least one cylinder bore during said open position and said flow of combustion air being prevented from communicating between said intake manifold and said at least one cylinder bore during said closed position;
