.When the engine is exposed to extremely coldl atmosphere, as for instance, when not properly housed in'winter seasons when the external projections of the explosion chest may radiate or dissipate more heat than is desired, the explosion chest is provided with 'a cover comprising a side walll 9 and a top ortion 9 and suitably mounted onthe cyl' inder head 1) or otherwise supported 'as may l0 provided with a lid 11 that is con-.

which a torch light or lamp maythe rod being composed of suitable highly expansible metal, such as brass. The upper end ofthe rod engages the lid 11 which will e closed when the rod is cold, and in oper- Aation the rod WillA expand and-force the lid that a How of air wi 1 be indue through the cover which is designed to exclude the excessively cold atmos heric air tions are exposed to accord approximately .fwithrevailing summer` temperatures; rr ough the engine is represented as be oil through the valve stroke of the-#piston z' air will be -forced1into-- the. airche'st lv and through the duct y to the chamberla-to inix openmore or less as may be redeterminegd so f'rom the projections s andv t, and t us modii. fyiiig the temperature to which theaprojecthe air pump which with the oil whichwill flow through the duct. 1 to the chamber 2,-.the movement of the oil being accelerated by air passing past the stem of the valve 3 to the duct'l; While the piston e is returning towards tl'ie head b and causing compression in the explosion 55 sulting instantly in the formation of perfect chest.,v the air pressure caused by the airf v'pump will force the-valvew open and vaporiz the charge of oil and air that may have become mixed vor .partiall y mixed in the chamber-e,disharg1ng the resultant hydrocarbon vapor inte` the explosion chamber to beigasified and ignited under`v compression by means of the heated internal projections pistone. The sizes of the oil charges maye chan ed or regulated by manipulating -or wings q, i rf, assisted by thel heat diie 'to compression, the explosion v"prodi'vicing the deslred 'force .for imparting motion to the higher degree with the `slightly increased number of explosions and therefore'the heat will beradiated or dissipated at a-higher rate, thus quickly reducing the temperature of the explosion chamber, and `therefore the internal projections, so as to prevent premature ignition, and so that a perfect combustion may not occur and therefore the speed of the engine will be slightly reduced.

The repeated explosions obviously will 1ncrease the tern erature of the internal projections, and t 's will' be re uired to maintain the average rate of spe with the load now increased, but if the load is .still decreasedthe governing of the speed will result as above-described. In some cases as hereinbefore indicated, the cover may not'be required on the explosion chest but when used will automatically regulate the pemperature about theexplsion chamber as a result of the varying temperatures expanding and contracting-` the rod 14.- to operate the lid 11 of the cover.

It will be observed that the'explosion chest has large capacity fas compared withv the cyIindeLarea, and when the air ump blows a spray of oil and airf into the exp osion chest While the piston e is beginning to compress the scavenging air ini the engine cylinder, the mixture spreads outagainst the heated walls and the wings of the explosion chest and becomes gaseous by reason of the heat, so that when the air is forced from the cylinder and compressed in the explosion chest, the air thoroughly mixes with the gaseous duid, re-

explosive mixture which ignites under compression by means of the hot Wings and walls of the explosion chest. Vhile it lis designedY that the walls and wings of the explosionchest shall become highly heated -so as to produce the explosions, 'excessive heat would ordinarily develop, and therefore the external projections or other suitable means are relied v on. to carry od surplus heat and thusmodify the results ofnlia'ting the internal wings, thereby preventing premature explosions.'

It will be' understood that it is 'customary d to provide -explbsive engines'with governors 'to regulate the supply of o1l.for'vary1ng loads, a gi-eatersupply of oil' being required when the load temporarily increases, and 1n such casesv the larger charges tend to raise.,V

the temperature of the explosion 4chamber excessively,y but such higher temperatures which would cause premature explosions are prevented by the external projections on the explosion chest.

Having thus described the invention, what is claimed as new is 1.

In .an explosive engine, an explosionchest having an outlet opening in the Wall thereof and havi also an inlet opening in a portibn of the wa outlet opening, a spraying device in the inlet opening to direct a spray into the explosion- -chest remote lfrom-the outlet opening, and a plurality of wings on the interior of the wall remote-from the outlet opening and within range of the spray.-

3. In an explosive-engine, an explosionchest havin an inlet opening and an outlet L opening in iferent planes, a barrier extendbetween the planes of the o enings,and prothereof remote from the i mg from the bottom of the explosion-chest jections on the interior o lthe wall of the explosion-chest at one side of the barrier near the inlet opening. 4. In an exp o sive engine, an explosionchest having an inlet opening in the upper portion and an outlet opening in the lower portion thereof in diierent planes, a plurality of wings on the interior of the wall of the explosion-chest at one side of the lane of the outlet opening, and a plurality o proj'ections on the exterior of the explosion-chest and extending laterally `from the sides and vertical-ly from he top thereof, portions of the wall having Wings onthe interior and a relatively greater number of projections on the exterior thereof.
