The invention discloses an oil injection timing lift measuring device for a marine medium-speed diesel engine. The device comprises a dial gauge supporting mechanism, a measuring lever, two tips, a measuring lever longitudinal moving mechanism and a measuring lever vertical moving mechanism, wherein a dial gauge is clamped and fixed in one end of a gauge rod clamping seat; the middle part of the measuring lever is hinged with a measuring lever hinging seat; the tips are separately fixed at the two ends of the measuring lever, one tip abuts against the lower side of a roller seat, the other tip abuts against a measuring head of the dial gauge, and the distances from the axes of the tips at the two ends of the measuring lever to the center of a hinge pin are equal; the measuring lever longitudinal moving mechanism is arranged between a horizontal rod of an upper right-angle bracket and one end of the measuring lever hinge seat; and the measuring lever vertical moving mechanism is fixed on the vertical rod of the upper right-angle bracket. According to the oil injection timing lift measuring device, the oil injection timing lift measurement data is more accurate, the tips can move longitudinally and lift vertically, the device can be applied to oil injection timing lift measurement of various diesel engine models, and the universality of the device is improved.
Description
technical field [0001] The invention relates to a fuel injection timing lift measuring device of an internal combustion engine, in particular to a medium speed diesel engine fuel injection timing lift measuring device with a rotational speed in the range of 300r / min to 1100r / min, belonging to the technical field of internal combustion engines. Background technique [0002] The gas distribution mechanism of a diesel engine uses a camshaft to achieve intake, fuel injection, and exhaust. In order to obtain better combustion characteristics, it is necessary to precisely control the time relationship between fuel injection and intake / exhaust, which is called "fuel injection timing". . When assembling the diesel engine, it is necessary to check whether the lift height of the fuel injection cam is within the allowable range when the crankshaft section of each cylinder is at the top dead center by cranking, and reassemble and adjust the camshaft section that does not meet the allowa...
