The invention includes an apparatus for retarding a turbocharged engine. There is a mechanism, such as a master and slave cylinder arrangement, for cracking open each exhaust valve of each cylinder of the engine near top dead center of each compression stroke. There is also provision for increasing the pressure of gases in the exhaust manifold sufficiently to open exhaust valves of other cylinders on the intake stroke after each exhaust valve on the compression stroke is so opened. The provision for increasing the pressure of gases in the exhaust manifold includes a device for diverting the exhaust gases to a restricted portion of the turbine nozzle, thereby increasing the pressure of gases directed onto the turbine blades and the pressure in the exhaust manifold.
