The invention relates to a plastic assembled engine model. A V type eight-cylinder automobile engine is taken as a simplified version, the structure is integral, the
simulation is strong, an
engine mount, a
sump panel, a low
crankcase, a
crankshaft, a connecting rod, a connecting rod head, a
piston pin, a
piston, a cylinder seat, a cylinder top plate, a cylinder cover, a valve rod, a valve top, a
crankshaft gear, a
crankshaft belt
pulley, a
camshaft gear, a
cam, a
camshaft, a
cam-pushed rocker, a
rocker arm fixed seat, a rocker sleeve, a
rocker arm, a
rocker cover, a gear cover, a fan belt
pulley, the crankshaft belt
pulley, a fan, an
exhaust pipe, a lower cover of the
exhaust pipe, a gearbox housing, a top cover, a filter, a filter cover and other parts are made of plastic, the
processing is labor-saving, the price is low,
rust dirt caused by
oil can be avoided, and the plastic assembled engine model is clean and sanitary; the working of a transmission mechanism constituted by the crankshaft, the connecting rod, the
piston, a cylinder and the like is in line with the requirements of an actual product, so that the plastic assembled engine model is conductive to understanding the engine by trainees and improving mechanical knowledge; and the motor is used for driving the rotation in reverse direction, and the operation is safe and has no danger.
