Abstract:
The present invention provides an internal combustion engine that provides advantages of both typical 2-stroke engines and typical 4-stroke engines, but using a new design unlike either. The present engine provides for use of pistons as means for opening and closing intake and exhaust ports disposed on cylinder walls. It also provides two pistons per cylinder in an opposing configuration, such that one fuel explosion event causes motion of both pistons per cylinder, in opposite directions. Each piston of a cylinder is connected to a separate crankshaft, which completes a single revolution about its axis per fuel explosion event in a cylinder. In a single cycle of piston movement along the cylinder, a full cycle of ignition, exhaust, intake, and compression is achieved.
Abstract:
A constant compression pressure and constant air/fuel ratio engine without an air throttle comprises an electric or hydraulic executive system, two-way cylinders, a distribution system, sensors, an electric control system and an electric spray system, and also comprises a multiple synchronous link position set, an upper and lower cylinder moving set, combined camshaft mechanism mounted on the distribution system or an electromagnetic air-valve control system producing an exhaling stroke, a fuel-feed system of constant air/fuel ratio and a compression pressure regulation system. A method of controlling knocking of the engine is also disclosed. The engine has five strokes and the function of constant compression pressure, variable displacement, a closed angle of a variable air-valve and knocking avoidance. The power consumption of the sucking stroke is smaller. The compression pressure, the inflatable amount and the air/fuel ratio under different work conditions are initialized artificially by the system regulated by the compression pressure. The engine can work and avoid causing knocking under the full work condition and the higher compression pressure. The engine can get the best compression pressure and air/fuel ratio during the whole process under different work conditions, which makes it more powerful, energy-saving and environment-protecting.

Abstract:
The variable valve operating mechanism (48) comprises lower and upper rocker arms (76a, 76b), each having a straight section (82) and a curved cam section (84). The lower rocker arm (76a) is mounted for pivotal movement about a fixed axis (70) and the upper rocker arm is mounted for pivotal movement about a shiftable axis (138). The free end (80) of the lower rocker arm (76a) engages the valve (24) to be actuated and the free end (80) of the upper rocker arm (76b) engages the straight section (82) of the first rocker arm (76a) when the shiftable axis (138) is spaced relatively far from the fixed axis (70). When the shiftable axis (138) is moved toward the fixed the axis (70), the valve (24) lift starts to increase. Continued movement, however, causes the engine's cam (40) to engage the curved cam section (84) of the upper rocker arm (76b) to lengthen the duration or time that the valve (24) is open. In this way, valve lift and the duration of time that the valve (24) remains open can be controlled in accordance with certain engine operating conditions. Provisions is made for lubricating parts of the mechanism and provision is also made for adjusting certain parts of the mechanism so as to provide a specified amount of valve lash.
