The turbo-charger uses the exhaust gas to increase the output of the engine by supplying
compressed air to the combustion chamber.
• Engines with turbo-charger air inlet systems require much more pumped and cool air.
(Maximum air consumption is 1,860 kg/h.)
• The fresh and cool air must be pumped into the engine compartment in order for the
engine to perform at normal power and fuel consumption.
• The temperature at the air inlet should be as low as possible. Hot air at the inlet will
reduce engine performance.
