INTAKE-MANIFOLD HEATER.
where the intake-manifold is bolted to the.
cylinder casting, to apply an external preheating device or the gaseous mixture as it passes throu h the intake-manifold. Such external app iances are not practical where the intake-manifold is cored in the cylinder casting. The object of the present invention is to obtain an internal heater for the intake-manifold cored in the cylinder casting.
Another object is to obtain a heater which extends longitudinally throu h the intakemanifold and is attachable t ereto. Other objects of the invention reside in the novel arran ements and combinations of parts as more lly hereinafter set forth. a
In the drawings:
Figure -1 is a sectional side elevation of the engine embodying my invention;
Fig. 2 is a sectional top plan view;
3 is a cross section on the line 3-3 'OfFl .1.
A is the cylinder casting of the engine forming the cylinders B, and C the exhaust manifold bolted to the casting and comthe valve-controlled ports F. The exhaust I manifold C is connected to the downwardl and rearwardly extending conduit G, whic' is connected to the muflier.( not shown).
For the purpose of' pre-heatin the as eous mixture in the intake-mani old be ore it passes into the engine cylinders, the en 'ne is provided with the tube or conduit connected to the forward end of the tube orconduit H and tothe exhaust manifold,
the inner end of the tube or conduit I being substantially flush with the inner wall of the Specification of Letters Yatent.
ports D. E is the inof said con extending longitudinally through the intakemanifold E and with the tube or conduit 1.
exhaust manifold. Suitable tubes or conduits J are connected to the tube or conduit H and extend downwardly and rearwardly beside the exhaust conduit G, the rear or free end of these tubes or condliits being open to the air.
For the pur se of readily attachin the tube or conduit H to the engine, the. atter v is of a len h such that both its forward and rear ends and K respectively extend out through the cylinder casting A. These ends are threaded and are engaged by the lock n'uts'L which engage in the recesses L in the ends of the cylinder casting. The ends K and K are also threadedly engaged by the elbows I and J respectively forming parts of the tubes or conduits I and J.
In 0 ration, the gaseous-mixture passing throng the intake-manifold E is heated -by means of the tube or conduit H extending through the intake-manifold and connected to the exhaust manifold so that a portion of the exhaust gases pass therethrou h. -Due to the'length of the tubes orcon uits connected to and forming the heater, the exhaust gases will not make an appreciable noise upon'passing into the air at the rearor free end thereof since the tubes or conduits have a mufiier effect.
What -I claim as my invention, is: 1. In an internal combustion engine, the combination with a cylinder block, of a Patented Apr. 27, 1920.
Application filed 'Apri122, 1918, Serial m5. 230,010.
water-jacket therefor, an intake manifold cored in said block and passing through said water-jacket to the ends of said block,
. and a conduit for exhaust gases extending through said intake manifold and spaced from the side walls thereof.
2. In an internal combustion engine, the
combination with a cylinder casting, of a water-jacket therefor, an intake-manifold cored in said casting and extending longitudina lly and to the opposite ends thereof and through said water-jacket, an exhaust manifold, a conduit extendin longitudinally through said 'intake-mani old, the ends ing, nuts threadedly engaging said ends for positioning, said conduit, and a conduit threadedly engaging one of said ends nd connected into said exhaust manifold. I
In testimony whereof I affix my signature.
