TURBO ENGINES PROTECTION DEVICE

In order to enhance the engine performance, the turbo charge is employed on a steady larger scale, for gasoline and diesel engines as well. But the price paid for he advantages provided by this technical solution is what in literature is named "the turbo death". The turbo engines are subject to considerable thermal strain.

Cooling system

A cooling system includes an electric pump, a cooling target temperature sensor, a coolant temperature sensor, and an electronic control unit. The electric pump pumps a coolant to a circulation channel connected to an inlet and an outlet of a cooling channel in which heat is exchanged with a cooling target. The cooling target temperature sensor detects a cooling target temperature. The coolant temperature sensor is arranged upstream of the inlet in the circulation channel, and detects a coolant temperature. The electronic control unit controls driving of the electric pump so that a discharge flow rate of the electric pump matches a target flow rate, and sets the target flow rate using an equation based on a reference value obtained by dividing a difference between the cooling target temperature and a target cooling temperature of the cooling target by a difference between the cooling target temperature and the coolant temperature.
