ABSTRACT:
A method and apparatus for quickly adjusting the coolant flow in a tuned, low-flow coolant system to maintain the temperature of air leaving an aftercooler at a desired temperature and for maintaining the temperature of an engine block within a predetermined range, during various engine loads and ambient temperatures. The invention employs a quick-acting, proportional radiator shuttle valve to mix hot coolant from the radiator input with cool coolant from the radiator output for application to the aftercooler and a quick-acting aftercooler shuttle valve to mix cool coolant from the radiator output with coolant from the aftercooler for application to the engine block.
