The camshaft may enable generation of suitable level of combustion residuals for the control of nitrogen oxide levels while minimising impact of the engine transient response. The camshaft may comprising a shaft body having a rotational axis, at least one exhaust cam for actuating an exhaust valve. An exhaust profile may be formed on the exhaust cam for actuating the exhaust valve to a first open position, the exhaust profile having an exhaust centre line. An EGR profile may be formed on the exhaust cam for actuating the exhaust valve to a second open position. The EGR profile has a maximum cam lift from 117.0° to 119.0° and a cam lift duration from 75.0° to 169.0° relative to the exhaust centre line.",
