Such cooling of the combustible fluid increases the density of the combustible fluid entering the intake port which results in an increase in the power of the engine. Since the combustible fluid is cooled by the intercooler or heat exchanger before entering the intake port, the temperatures of the rotor and housing assembly are also reduced, thus increasing the durability of these parts.
Another principal feature of the invention is the provision o~ the intercooler or heat exchanger having cooling means comprising internal fins located within the transfer passage and external air cooled fins integrally connected to the internal fins so that the invention can ~ -; utilize the air from a cooling fan on an air cooled engine.

Claim 5 continued combustible fluid to said intake port, said intercooler having means for cooling the combustible fluid flowing therethrough before delivery of the combustible fluid to said intake port.
6. A charged cooled rotary combustion engine in accordance with Claim 5 wherein said internal passage in-cludes a first lateral passage located in one of said first side housing and said rotor for communication with said axial passage and said inlet, and a second lateral passage located in one of said second side housing and said rotor for communication with said axial passage and said outlet.
7. A charge cooled rotary combustion engine com-prising a housing assembly including a trochoid-shaped housing and a pair of side housings secured together to define a trochoid cavity, said housing assembly also having an in-take port in communication with said trochoid cavity, a rotor supported by said housing assembly for rotation within said trochoid cavity, an internal passage located in one of said side housings and said rotor and adapted for communica-tion with a source of combustible fluid, whereby to effect cooling in response to a combustible fluid flow through said internal passage, said internal passage including an inlet and an outlet extending into one of said side housings and a lateral passage located in one of said one side housing and said rotor for communication with said intake port and with said outlet for receiving combustible fluid from said outlet and delivering combustible fluid to said intake port, said intercooler having means for cooling the combustible fluid flowing therethrough before delivery of the combustible fluid to said intake port.
