AIR COOLER TUBES FAILURE Reasons for Turbo charging are: 1. Increased air charge density permitting more fuel to be burned. 2. Increased engine output. 3. Reduced thermal load on engine mechanism. 4. Improved Scavenge efficiency of engine Turbocharger is compressing the air thus an increase in charge air temperature will transpire. This will trim down the density of the air entering the engine. To reduce this effect the air is cooled. This is the function of the Air cooler. Cooling the air also reduces the thermal load. The volume and density of scavenge air establishes the maximum amount of fuel that can effectively be burned in a diesel engine. An efficient heat transfer across the air cooler will lower the air temperature whereby increasing the density, which ultimately results in an increase in air compression, mean effective pressure and combustion rate. This will eventually also lead to reduced specific fuel consumption and NOX emissions. However, scavenging air dra...
