Abstract

The piston engine cooling system includes multiple pistons rotatably coupled to a crankshaft. Each piston includes a piston head defining a cooling chamber therein, and a connecting rod coupled to the piston head. The connecting rod includes a connecting rod inlet channel therein allowing oil to enter the cooling chamber, and a connecting rod outlet channel receiving oil exiting the cooling chamber. The crankshaft defines a crankshaft inlet channel allowing oil to flow through the connecting rod inlet channel, and a crankshaft outlet channel receiving oil flowing through the connecting rod outlet channel.
