Title: Heated reaction chamber for engine - has liquid fuel injected for part combustion with air and exhaust gas mixture
Inventor: ROESSEL HEINRICH
IPC: F02B19/02
Filed: 1975-07-10
Abstract: The combustion engine incorporates a reaction chamber which is heated up to a high temp. The channel which connects this chamber to the engine cylinder can be closed by a valve. This valve is closed during the compression stroke of the engine. While the valve is closed, the liquid fuel is injected into the reaction chamber which is filled with air of a mixture of air and outlet gas. During the fuel injection, part combustion takes place by which the remaining fuel is turned into gas. When the valve, connecting reaction chamber and cylinder, is opened, the compressed air enters the reaction chamber. The air mixes with the hot gases which are still partly reacting and the main combustion is introduced. The ignited mixture flows back into the cylinder.

Title: Energy recovery from liquefied gas expansion - by heat exchangers with recycled gas, expansion turbines and closed brine circuit
Inventor: POCRNJA ANTON DIPL ING
IPC: F02C1/04
Filed: 1976-02-04
Abstract: The energy stored in liquefied gases (liquefied natural gas) is recovered when it is converted back to gas by passing through two heat exchangers with expansion turbines for re-cycled gas in the circuit. A third heat exchanger uses a brine solution where the cold can be transferred to a refrigeration plant. The highest temp. achieved in the whole circuit does not exceed ambient temp. The cold can thus be recovered at a temperature level of 223 K to 243 K. This eliminates both the waste of fuel energy for reheating the liquefied gas, and the environmental pollution by waste gases. The thermodynamic efficiency has been raised to an optimum.

Title: Regulator for IC engine exhaust brake systems - has engine speed dependent pneumatic switch to relieve exhaust pressure
Inventor: FUHRMANN WOLFGANG DIPL ING
IPC: F02D9/06
Filed: 1976-07-27
Abstract: The regulator influences the pull side in the main brake cylinder to avoid peak pressures and subsequent engine damage. The exhaust pipe (3) has a pivoted brake flap (4) whose spindle is mechanically connected to a brake cylinder piston rod (8). The brake flap is h eld in the open position by a coil spring (11) fitted inside the cylinder on the push side (9) of the piston. Air pressure (14) introduced by the foot brake valve ( 13) on the push side (9b) of the piston (10) overcomes spring pressure to close the brake flap. Breaking occurs because the engine is drawing in air and unable to expell it as in 625095. An air pressure sensor (57) is fitted between engine block and cooling fan (58) to actuate a servo piston (50a) when the engine revolution speed exceeds a threshold limit. The servo piston is displaced to close a pneumatic switch (54) which stops the brake cylinder vent pipe (51). This allows compressed air from an auxiliary supply (54) to flow into the brake cylinder (9) via a restrictor and a non return valve.
