Definitions
- the present invention relates to a three-stroke compound engine of internal combustion type.
- the purpose of the invention is to provide an internal combustion engine which is less power- -consuming than engines known so far and which can be operated by mixtures of gasoline and alcohol or the like.
- a further purpose of the invention is to provide an internal combustion engine which for a desired output can be made smaller than conventional engines and which can be manufactured at lower costs.
- FIG.. 1 illustrates di agrammatf cally the sucti on stroke of the engine
- FIG. 2 illustrates diagrammatically the expansion stroke of the engine
- FIG. 3 illustrates di agrammati cally the exhaust stroke of the engine.
- crank rod 3 pivoted to the piston at one end thereof.
- the other end of the crank rod is rotatably mounted to the crank of a crank shaft 4 for converting the reciprocating movement of the piston to a rotational movement of the crank shaft.
- inlet or suction valve 5 and an outlet or exhaust valve 6 which are controlled so as to be opened and closed by means not shown in the figures.
- FIG. 1 illustrates the suction stroke of the engine.
- the inlet valve 5 is open while the piston is moving to the right as seen in the figure.
- the valve opening is dimensioned so that the total amount of fuel or fuel mixture required for the combustion during the following expansion stroke, will be sucked into the cylinder during a movement of the piston 2 comprising a fraction only of the total stroke of the piston.
- the valve is rapidly closed, the fuel mixture sucked into the cylinder at the same time being instantly ignited.
- the expansion obtained during the following combustion causes the piston 2 to continue the movement to the right over the remaining portion of the total stroke of the piston, the crank shaft 4 accordingly being rotated.
- the outlet valve 6 will be opened.
- crank shaft two or more cylinder piston units of the kind described can be connected such that the crank shaft at any time is rotated under the influence of the piston movement in one of the cylinders .
