摘要： PROBLEM TO BE SOLVED: To provide a small and lightweight 2-cycle engine of a simple design, which is suitable for being inserted into an small capacity automobile, is structurally symmetrical, and has a low production cost. SOLUTION: This 2-cycle engine has valve driving means within a valve drive housing 12 to reversibly move a valve member having a head and a stem, and houses upper and lower steps which form a combustion chamber 54 that includes a reversibly movable piston member. The upper step has at least two intake ports 56 and a fuel injection port, and ignition means 60 which ignites a mixture of fuel and air. The lower step has an exhaust port 62 which discharges exhaust gas. In addition, this engine also has a cylinder housing which is vertically in line with the drive housing to which it is fixed, and crank housings 90, 92 which are connected to the lower step 52 of the cylinder housing that includes a crank which is connected to a piston, and an oil pan.

摘要： A two stroke cycle internal combustion engine (10) is provided which has a one-piece cylinder housing (14) removably secured to a valve drive housing (12) at a top section thereof and a crank housing (16) at a bottom section. The overall combination of the valve drive housing (12), the cylinder housing (14) and the crank housing (16) are formed in a substantially symmetrical manner about a vertical axis line (18). An intake valve member (30) is positioned in a top section of cylinder housing (14) with an exhaust port (62) located at the bottom of a piston (44) travel within a combustion chamber (54). The valve member (30) opens on a downward stroke of the piston (44) which feeds compressed air into chamber (54) and forces spent gases through the exhaust port (62). Fuel is injected into the combustion chamber (54) prior to the peak of the compression segment of the overall combustion cycle. The valve member (30) is formed of a substantially non-magnetic composition and is secured to a permanent magnet (32) which acts in cooperation with a reversible pole electromagnetic drive (28). With the one-piece formation of the component elements in combination with the symmetrical contour of overall engine (10), there is provided a higher engine efficiency coupled with a substantially cleaner combustion and allows for a modular design to simplify the construction and manufacturing of two cycle engine (10).
