摘要： A piston of a gas engine is reciprocatingly guided in a cylinder. A gas inlet valve whose valve closure component consists of a ball is situated in the cylinder head. The ball is pushed open in the top dead-center position of the piston by a protrusion formed on the upper portion of the piston in order to admit propellant gas into an expansion chamber formed by the cylinder. The gas engine must be set into operation by turning a crankshaft. If the piston accidentally lies near top dead-center when starting, the piston must be moved against full gas pressure. In order to alleviate starting, a shut-off device is provided which has a start position and an operational position. The shut-off device connects the inlet side of the gas inlet valve with an air conduit opening into ambient air and obturates a pressurized gas container in the start position. The shut-off device obturates the air conduit and clears a gas supply conduit leading from the pressurized gas container to the inlet side of the gas inlet valve in the operational position. With the help of this shut-off device, it is possible to start even gas motors equipped with gear-reduction transmissions.

摘要： The diesel engine has the cylinders divided into two sets. During starting a transfer valve (23) allows air compressed in one set of cylinders (14) to enter the other set (15) to supercharge this set and aid starting. The engine is turned over for starting by compressed air admitted to all cylinders by starting valves (32). The starting valves are operated by a control (30) which is connected to the crankshaft. The control has a further output (34) to the transfer valve (23). It closes the transfer valve when the starting valves (32) are open. This prevents the transfer air from acting against the starting air.

摘要： 1373387 Cooling IC engines E W WHEELER 21 Dec 1971 59322/71 Headings F1B and F1K An IC engine drives an air compressor the output air from which is passed through a jacket surrounding the engine so that the air is heated in cooling the engine and is then stored in one or more accumulators in order to be available for supercharging the engine. Rotary compressor A is mounted in front of the engine on the vehicle and supplies air at 40 p.s.i. which is cooled before passing to an accummulator D containing a piston loaded by a first-stage spring to give 20 p.s.i. and a second stage spring to give 40 p.s.i. From the accummulator the air passes to two cylinders of the engine which further compress the air to 280 p.s.i., at which pressure it is exhausted into an air jacket J surrounding the engine to act as a coolant. Air leaving the jacket J is stored in a second accummulator G of about 2 cu. ft capacity which again contains a piston loaded by two springs. The first spring produces a pressure of 60 p.s.i and the second spring a pressure of 250 p.s.i. Starting A third accummulator H also receives air from the jacket J and has a piston, spring- loaded to produce 100 p.s.i., the air from this accummulator being used to start the engine. The engine having been stopped by raising the accelerator pedal beyond the slow-running point, depression of the pedal opens a valve connecting the accummulator H to the engine. The valve is automatically closed by the back pressure when the engine fires. Conserving heat The exhaust pipes pass around accummulator G to heat the air therein. Engine temperature control Since the output of the compressor is proportional to engine speed, the amount of cooling air supplied will vary automatically with the speed of the engine, an excess of air being provided which is released through a valve L controlled by a thermostat in the wall of the air jacket J. A further valve M controlling the outlet from valve L is controlled by the pressure in accummulator H and closes to maintain 100 p.s.i. in the accummulator, even though cool running of the engine may have caused the thermostat to open fully the valve L.
