SPECIFICATION Inventor: Otto Fahl TITLE Combination Engine or for short: Coengine ABSTRACT New internal-combustion engine combining a double-acting piston, or pistons, with valved two-stroke function, and having a fuel gasifier supplying hot, high-pressure gaseous fuel by means of a special safety metering-valve system into the cylinders for precise and complete combustion at all loads and speeds. In this engine system each stroke is a power stroke and all mass forces are compensated by gas pressure, thus reducing greatly friction. Piston faces and cylinder heads have insulation layers, leaving more work for the piston and a special pulsed exhaust turbine which therefore can deliver additional work besides driving the compressor. Supercharging ability and a special overcharging system, which can enlarge the combustion space automatically, increase greatly the maximum power output without affecting adversely the high overall thermal efficiency at low power. This engine is therefore well suited for car and truck engines and for heat pump applications with total heat recovery. - 1 -
