Abstract

DC60 (19/03/44) First and second compression limiter. Mounted on the camshaft That rotates between Lower camshaft bracket and upper camshaft bracket. Fixed to the upper surface of the cylinder head 1, therefore the first and second compression limiter The second compression limiter - protrusion is located on the outer periphery in there, so the protrusion - measuring is measured. By the TDC 37 sensor mounted on the engine head cover, so the rotational position (phase), angle of rotation And the rotation of the engine crankshaft, such as a 6e camshaft and crankshaft. Able to accurately measure structures with reduced number of pieces. And the axial size of the rotating shaft Of the engine can also be reduced First and second compression limiter Mounted on a camshaft that rotates between The lower camshaft retainer and the upper camshaft retainer are fixed to the upper face of the cylinder head 1, so the first and second compression limiter are aligned with the 95 and 105 camshaft retainer. Second compression There are protrusions for measuring on the outer edges in there, so the protrusions are used to measure. It is measured by a TDC 37 sensor mounted on the engine head cover. (Phase), angle of rotation And the rotation of the engine's rotating shaft, for example The 6e camshaft and crankshaft can be accurately measured. In a structure with a lower number of pieces And the axial size of the engine's rotating shaft can also be reduced.
