• As predicted exclusively by CM three months ago, Foden has become the first European truck manufacturer to offer the latest air-to-air charge-cooled (ATAAC) ver sion of the Caterpillar 3306B diesel engine.
The 10.6-litre ATAAC engine is rated at 224kW (300hp) at 2,100rpm and has a peak torque of 1.288Nrn (950 IVO delivered at 1,350 rpm. Both figures are to BSAU 141a.
Cat ATAAC engines have 'been available in America for just over 12 months and according to Caterpillar's tests can reduce fuel consumption by up to 5% compared to airto-water charge-cooled engines. Most loose engine suppliers still prefer air-towa t er.
Caterpillar opted for air-toair charge cooling after extensive evaluation tests on air-towater systems, including one and two pump low-flow designs. It says that air-to-air cooling achieves and maintains a lower average inlet air temperature throughout the engine's operating range.
Intake air is drawn through the turbocharger where it is heated to about 150° Celsius. It is then ducted through a radiator, mounted ahead of the engine, where its temperature is reduced to about 43° Celsius before it enters the inlet manifold.
The air-to-air radiator is cooled by the engine fan as well as by air passing through the engine compartment.
Foden has carried out its own tests with the engine, in conjunction with a number of its fleet customers. Foden's sales and service manager Roger Smith says results have been consistently good across a wide range of applications.
The Cat ATAAC engine will be available as an option in all Foden trucks.
