Abstract
Several embodiments of V-type outboard motors having direct cylinder injection using electronic fuel injectors driven by a solenoid driver. The solenoid driver is mounted in the otherwise void area between the cylinder banks of the engine. The solenoid driver is also cooled so as to provide long life and good operation. The cooling can be either by air or water or both. Mounting the solenoid driver in the valley between the cylinder banks also permits shortening of the conduits from the solenoid driver to the solenoids of the injector valves for their operation.
Claims20
A V-type, multi-cylinder internal combustion engine having a pair of cylinder banks with a valley formed between the cylinder banks, a plurality of fuel injectors mounted in said engine, each for spraying fuel directly into a respective combustion chamber of said engine, said fuel injectors having electrically operated solenoid valves for controlling the discharge of fuel therefrom, an injector driver mounted in said valley between said cylinder banks and spaced well between the ends of said engine for supplying electrical power to said fuel injectors for operating their injector valves, and a heat exchanger mounted on an external surface of said injector driver for cooling said injector driver.
