ABSTRACT:
An engine clamping apparatus is provided for firmly fixing engines having different fixing points. The invention includes a cylinder serially accommodating an upper and lower piston for providing a shorter rising stroke when supplying an oil pressure so that a rising stroke of the lower piston pushes up the upper piston, than upon supplying the oil pressure so as to push up only the upper piston. The engine clamping apparatus also includes an operating rod extended to top portion of the upper piston, a groove formed in a side of a body of the operating rod, a rotating grip pivotable about a hinge shaft and having one end bound in the groove, and a fixing bar horizontally projected at a free end of the rotating grip, the fixing bar being pushed into a fixing hole of an engine so as to fix the engine when the operating rod is raised and a free end of the rotating grip is lowered.
