A diesel engine, in particular a high-power diesel engine, which has a variable valve train including an adjusting unit for adjusting a valve opening time, a valve lift, a camshaft phase position and/or a valve steering, and a control or regulating unit for controlling the adjusting unit. The control and/or regulating unit includes at least one operational mode provided for starting the engine when the engine is at a low temperature, in which the control and/or regulating unit is provided to adjust the valve opening time, at least during a preliminary phase for at least one inlet valve, which overlaps at least with one compression stroke of an associated cylinder, and to interrupt an injection of fuel at least into the cylinder associated with the inlet valve. The invention also relates to a method for starting such a diesel engine.
