Abstract

In a motorbraking arrangement for a Diesel engine with at least one engine breathing valve and at least one fuel injector per cylinder and a high pressure fuel pump with a high pressure fuel reservoir for supplying high pressure fuel to the injectors, a control valve is provided for controlling the supply of fuel from the high pressure fuel reservoir to the breathing valve for its actuation during an engine compression stroke and a lower pressure fluid supply system is provided for operating the breathing valve during normal engine operation under the control of switch-over means which place the breathing valve in communication either with the high pressure fuel reservoir or with the lower pressure fluid supply system.
