This invention relates to a cooling system for an internal combustion engine, and is particularly suitable for cooling emission gases from electronically controlled, Tier 3 fuel injection engines [12] used in trackless mining machinery, wherein the fuel injection engine [12] includes an exhaust manifold [14], a turbocharger [16], and a catalytic converter [18] through which the emission gasses sequentially pass before they are released to atmosphere. The cooling system [10] comprises an exhaust manifold housing [20] for at least partially encasing the exhaust manifold [14], a turbocharger housing [34] for at least partially encasing the turbocharger [16], and a catalytic converter housing [92] for at least partially encasing the catalytic converter [18]. The cooling system [10] also comprises an exhaust cooler [118] adapted for rapidly cooling emission gasses exiting the catalytic converter [18] before they are released to atmosphere. The cooling system [10] is characterised therein that engine emission gasses are maintained at relatively high temperatures until after they pass through the catalytic converter [18], and thereafter undergoes rapid cooling as they pass through the exhaust cooler [118].
