Modular cylinder deactivation mechanism in a connecting rodless piston engine
Abstract
The paper describes a mechanism for modular cylinder deactivation in a connecting rod-less engine. An engine with such a mechanism can provide high fuel efficiency and reduce the amount of unburned hydrocarbons CH by improving the working process in the operating cylinders when cylinders are deactivated under low load conditions. The paper presents a design solution for the mechanism for modular cylinder deactivation by stopping the piston installed in a connecting rod-less engine containing two crankshafts in the crankcase and a linkage that can disconnect the kinematic connection with the piston rod using a rod locking unit and a rod locking control unit. The rod locking unit makes it possible to exclude or allow linear movement of the rod relative to the rotating crankshafts, thereby ensuring, respectively, the inclusion in operation or stop of the piston, i.e., cylinder deactivation. The article shows the operation of one of the design options for the mechanism for modular cylinder deactivation. The advantages and disadvantages of such a solution are analyzed. The obtained design of the mechanism for disabling cylinders by stopping the piston in a connecting rod-less engine with a crank-rocker mechanism is promising and can provide a significant fuel saving effect when disabling cylinders
