Cooler Under Pressure
NISSENS explains the common issues faced by intercoolers because of more cars being fitted with turbocharged engines.
With the demand for smaller, yet more powerful, fuel-efficient and low-emission engines on the rise, the trend for more passenger cars fitted with turbocharged engines is growing proportionately as well. Currently, more than 43% of the EU car parc is fitted with a turbo. This figure is expected to increase by 30% by 2019.
PROS AND CONS
Since its introduction more than 30 years ago, turbochargers have halved in size whilst RPM and pressures have doubled. This has led to the increase of air temperature within the system that then needs to be cooled in order to gain the desired effect. The vast benefits of turbocharged engines are evident as they optimise the systems by pushing them to the limit.
However, turbocharged engines do cause some issues. As the difference between the input and output air temperature of the intercooler is increased due to the turbo, it puts the intercooler under more pressure and strain. This can lead to failure if the turbo and intercooler are not installed properly.
