T 0 all whom it may concern:

, Be it known that I, JAMES Governors PEACHE, engineer, a subject of the King of Great Britain, residing at Victoria 'or s. Rugby, in the county of Warwick, England, have invented new and. useful Improvements in Internal-Combustion Engines, of which the following is a specification. In engines working under the Diesel system it is customerto introduce the fuel by, means of air un er compression supplied from storage. cylinders.

In ractice it is found that as the amount elis cut down to suit a decrease of load, the consumption of com ressed air increases perfect owin to the cooling effect of the air introducing t 1e fuel.

v This invention has for its object. to dispense with the compressed air reservoirs now re- 1 quired for injecting the fuel, to use a nnni- 1 mum-0f compressed air whether injecting 5 Specification of Letters Patent.

he apparatus described above is fixed in the cylinder head of an internal combustion engine, and the cycle is timed so as first to draw in fuel and air, and compress theair, and then eject the air and fuel into the working cylinder as the main piston begins to make its working stroke.

The spring e which holds the valve in place can be tightened up to any desired extent.- If this device is applied to a Diesel engine much or little fuel, and to su ply this com- 1 which works under a compression of say 500 pressed air in a highly heate state so that 1 lbs. per square inch, the spring would be set there shall beno coolin efiect but on the so that the valve shall not lift until say a other hand a considerab e heating and vappressure of 700 lbs. per square inch is proorizing effect on the incoming fuel.

The extent of the heating and the fineness of the atomizing can be readily regulated while the engine is at work by adjusting the tension of the springholding the valve to its seat.

The combination of a cylinder, a valve seat at the end of the cylinder of the sam diameter as it, a valve resting on the seat and closing the end of the cylinder, a spring tending to close the valve, :1 plunger working in the cylinder, means for reciprocating the plunger up to and away from the valve, and means for supplying fuel and air to the cylinder.
