US 4,480,611 A · Internal combustion engine using several kinds of fuels, with electronically adjustable intake and exhaust valves and injection device

Abstract

The combustion engine using several kinds of fuels is provided with intake and exhaust valves and an injection device which may be electronically adjusted. It is comprised of at least one working cylinder (1, 1a) at the upper part of which is provided a fuel supply device (4), an intake valve (5) and an ignition device (6); these elements being all electronically adjustable. In the working cylinder (1, 1a) there is provided a piston (9) which is in communication with a pressure accumulator device. This connection device may be comprised of a hydraulic, pneumatic accumulator or even a spring accumulator. The piston rod (12), provided with a blocking device (11) is connected to a transmission shaft (15), (15a). To regulate the running of this engine, there is provided an indicator (3) of the cylinder temperature, a piston position indicator (34) and an electronically programmable adjusting and control device (20), such device (20) possibly being a microprocessor (20a). The control and adjusting device (20) has a display unit (51); this device (20) is connected with the temperature indicator (3), the piston position indicator (34) and, via a switch (21), with the fuel supply device (4) and the intake valve (5).
