Patent DE-4039343-A1 (DE)
Title: Free-piston IC engine - has turbocharger system and piston moving in U=shaped channel
Inventor: KOENIG JOHANNES
IPC: F01C11/00
Filed: 1990-12-10
Abstract: The engine (1-12) directs a direct drive force, by exciting a rapid sequence of centrifugal force impulses. A piston is oscillated in a housing with a semi-circular guide channel, by combustion pressure. Fresh air/exahust control is by the free, oscillating piston, which controls one inlet and two outlet slots. - At atmospheric pressure, fresh air is processed by fuel injection into the compression channel of the turbo-charger. For use in space, combustion air and oxygen are contained in pressurised tanks, and processed in a special mixer. The fuel/air mixture is ignited by compression heat, at self-ignition temp. Starting of the engine is via outlet valves. For starting a starting compressor or oxygen tanks are required.

Title: Fuel pump for diesel engine with optional plant oil feed - has simultaneous changeover of maximum torque setting with fuel selection control, compensating loss of performance on changing from diesel to plant oil
IPC: F02B3/06
Filed: 1991-11-04
Abstract: The fuel pump enables a diesel engine, started with normal diesel fuel, to change over to a more viscous plant oil once the engine is warm.

This compensates for the different effects of the two fuels and enables sufficient torque to be generated using the more viscous fuel. The change-over can be via solenoids, using a common drive current. A mechanical control can also be employed, with a direct mechanical link between the fuel selection and the stop adjustment. ADVANTAGE - Simple changeover control, compensation for fuel efficiency. Engine can be run normally on diesel in absence of plant oil.
