Detailed 3D model of a complete four-cylinder internal combustion engine with common rail fuel injection system. The assembly features fully modeled critical components including a multi-bearing crankshaft, connecting rods, pistons with wrist pins, cylinder block with integrated bores, cylinder head assembly, valvetrain (including valves, springs, and rocker arms), camshaft with lobes, and injection nozzles. The design employs a conventional overhead valve (OHV) configuration with the camshaft positioned to actuate the valves through rocker arms. Notable design features include the oil sump pan for lubrication system integration and cap screws for component fastening. The model is constructed at 1:1 scale in millimeters, with the overall engine block dimensions approximately 600mm in length, accommodating the four inline cylinders with appropriate clearances for thermal expansion and mechanical movement.
