Abstract:
An internal combustion engine fueling and compression braking system, comprising:an engine cylinder; a fuel injector for injecting fuel into said engine cylinder so as to be combusted; a fuel injector piston for causing pressurization of fuel to be delivered to said fuel injector; an exhaust valve operatively associated with said engine cylinder for controlling the exhaust of gaseous products from said engine cylinder; an exhaust valve rocker arm operatively connected to said exhaust valve so as to control opening of said exhaust valve when exhaust of gaseous products from said engine cylinder is desired; a compression brake actuating system for operatively interconnecting said piston to said exhaust valve rocker arm; and a control system operatively connected to said compression brake actuating system for alternatively disposing said compression brake actuating system in two different modes wherein when said compression brake actuating system is disposed in a first one of said two different modes, said compression brake actuating system is operatively disconnected from said piston such that movement of said piston causes normal engine fuel injection to occur, and wherein when said compression brake actuating system is disposed in a second one of said two different modes, said compression brake actuating system is operatively connected to said piston such that movement of said piston causes said compression brake actuating system to actuate said exhaust valve rocker arm so as to in turn actuate said exhaust valve such that compression braking can occur.
