Abstract:
A method for providing exhaust gas recirculation in a multi-cylinder internal combustion engine, said method comprising:providing a plurality of cylinders in a multi-cylinder internal combustion engine with cylinder heads configured so that each of said cylinders is connectable in fluid communication with a common exhaust manifold via an exhaust port formed in a respective head of the cylinder; providing an exhaust gas recirculation passage through an adapted one of said cylinder heads of said plurality of cylinders for recirculating exhaust gases from said exhaust manifold to an air intake side of said engine, said exhaust gas recirculation passage being at least partially constituted by said exhaust port formed in that adapted one of said cylinder heads; and operating said multi-cylinder internal combustion engine so that recirculation exhaust gas from each of said plurality of cylinders passes through the adapted one of said cylinder heads toward the air intake side of said engine.
