PISTON MACHINE CURRENT CYLINDER VOLUME CONVERTER DEVICE Russian patent published in 2005 - IPC

FIELD: internal combustion engines.

SUBSTANCE: device has serially connected optical position indicator, pulse set-point generator, low frequency filter, control signal generator, differential cascade, saw-shaped signal generator and sinα function generator, which through commutating device are connected to filters packet input, output of which is connected to inputs of generators of sin2α, sin²α, cosα and to first input of first adder device. Outputs of generators of sin2α and sin²α are connected respectively to first inputs of first and second multiplication devices. Scale converter of λ_d value is connected to second inputs of first and second multiplication devices, output of first of which is connected to second input of first adder device, while outputs of second one, generator of cosα and time scale converter of value ε are connected to inputs of second adder device, output of which is connected to first input of third multiplication device, and its second input - to V_h value scale converter. Control of converters for λ_d, ε and V_h is performed by operator using device control panel.

EFFECT: simplified construction, higher precision, higher efficiency.
