Problems solved by technology

[0003] 1. Since two cams are arranged on one camshaft, the length of the camshaft is relatively long, resulting in a relatively large volume of the crankcase, which is extremely unfavorable for portable generators
[0004] 2. Since the camshaft is set parallel to the crankshaft, and the two cams are located on one camshaft, the connection line between the two valves must also be parallel to the camshaft, and the cooling air in the unit is also parallel to the crankshaft and the camshaft Therefore, the cooling air goes along the line between the two valves, which is extremely unfavorable for the heat dissipation of the cylinder head

Abstract

The invention discloses a portable engine installation of electric generator, comprising air cylinder in head and crankshaft in box. The piston in cylinder drives crankshaft, which drives cam shaft through gear, through connector. The cam on cam shaft drives tapper arm, which drives pushing bar. The pushing bar controls switch of air gate through swing arm. There are two paralleling said cam shafts, which are parallel to crankshaft respectively. One cam is set on each cam shaft. Previous mechanism can not only reduce the cubage of crankshaft box but also accelerate heating of cylinder head dispersed.

Description

technical field [0001] The invention relates to an engine device of a portable generator. Background technique [0002] Portable generators currently on the market include an engine and a generator driven by the engine, both of which can be installed in a sound-proof box body with a carrying handle on the top, so as to be convenient for users to carry. A traditional engine includes an upper cylinder head cylinder and a lower crankcase. The cylinder head is provided with a cylinder, and the upper end of the cylinder is provided with an intake valve and an exhaust valve. The piston in the cylinder drives the crankshaft located below through the connecting rod. Drive the generator to generate electricity. At the same time, the crankshaft also drives the camshaft parallel to it through the gear. There are two cams on the camshaft. The two cams touch the upper tappet respectively, and the tappet touches the upper push rod. The rod drives the valve switch through the rocker arm. ...
