ABSTRACT:
An engine brake system for use in all types of diesel and gasoline engines, comprising a control means disposed, in the main embodiment of the invention, on the top of the line of valve rocker arms, seated on the supports of the rocker arms, and a dislodgement valve installed in the intake manifold of the engine, the valve remaining closed until the brake system is applied. An actuating device acts when the brake is applied, longitudinally displacing the control means, whereby the rocker arms of the exhaust valves are uncoupled from the corresponding tappet rods thereby impeding the exhaust valves to open, whereby the gases trapped in the cylinders put up resistance to the ascending movement of the pistons in their exhaust stroke. The discharge of the gases toward the environment, via the dislodgement valve, occurs when the opening of the intake valves begins at the start of the intake stroke of the pistons.
