BATEMZAN DAVID SCOTT, OF STBETFORD, MANCHSTER, AND WILLIAM HENRY TATE,
OF SALE, ENGLAND.
INTERNAL-COHBUSTION ENGIN E.-
Speciflcation of Letters Patent. Patented Feb. 25, 1919.
Application filed November 13, 1918. Serial No. 262319.
To all whom it may concem:
Be it known that we, BATEMAN DAVID 'Soon', of 53 Moreton avenue, Stretford,
Manchester, in the county of `Lancaster, England, and WILLIAM HENRY TATE, of 7 Westbourne Grove,Sale, in the count of Chester, subjects of the King of reat Britain and Ireland, have invented certain throu h the injector or sprayer h which is new and useful Improvements in Internal- Combustion Engines, of which the following is a specification.
This invention relates to internal comno air is admitted to the c lmder until the pisten approaches the en stroke. e V
Referring to the accompanying explanatory drawing,'the pisten a works within a of the suction sleeve b which is reciprocated'by suitable means, such as the crank a and controls ports d, e in the cylinder f. The port e serves as the engine exhaust port and the port d as the air inlet port, the amount of air admtted through the'said port being regulated by the rotary throttle valve g.
.The fuel is admitted to, the cylinder 4 capab e of very fine adjustnent and is opened mechanically at the required periods.
Or,'it may open automatically. against the pressure of its spring during thesuction The use of an injector or sprayer stroke. enables us to work the engine on heavy fuels 'and to obtain complete atomization and. va
porization of the charge prior to combustion.
The ports z', y' in the sleeve b and the ports d, e in the cylinder are so positioned with relation to one another and to the movement of the sleeve and pisten, that the exhaust port is uncovered just prior to the completion of the power stroke of the pisten and remains open throughout the exhaust stroke.
The continued movement of the pisten results in the production of a Vacuous condition in the cylinder during the period in which fuel is entering through the injector 'h until the port d is uncovered, when there is a strong inrush of air which results in a complete difl'usion of the fuel throughout the charge ready for ignition and combustion.
Instead of employing a single port for the exhaust and for the inlet, we may employ a set of ports disposed around the cylinder;
OWing to the large area which may be given to the exhaust and inlet ports and to the lightness of the valve mechanism with our improved construction, the engine s particularly suitable for high speed work.
By arranging the, exhaust and the inlet ports .at the opposite ends of the single sleeve,^as shown,` lubrication of the hearing surface between sleeve and cylinder is effected by the oil vapor drawn from the crank' case by the engine suction, and distrbuted during working. No oil gains access `to .the cylinder at theupper end of the sleeve and so adirty exhaust and heavy de posits in the cylinder and-exhaust fittings, are prevented.
We do not limit ourselves 'to any articular means for actuating'the sleeve nor to the number or disposition of the cylinders i constituting the engine. The latter may be air or water cooled according to ments Having now described our nventon what requirewe claim as new and desire to secure by Letters Patent is 1. In internal combustion engines of the four cycle type, the `cornbination with the engine piston and cylinder; of a valve sleeve around the pisten and between the latter and the cylinder, air inlet and exhaust ports at the opposite ends of the cylinder, ports in the said sleeve, means for opera ting the sleeve to control the cylinder ports and a fuel sprayer in the cylinder head for deliveringfuel into said cylinder during the suction stroke and before the air inlet port is opened.` v
2. In nternal combustion engines of the four cycle type, the combination with the engine pisten and cylinder, of a valve sleeve around the-piston and between the latter and the cylnder, an exhaust port adjacent the eylnder crank case said sleeve for re ports, means for operatn trol the cylin the cyln said eylin ort adj acent the er, ports in the opened. th the oylnder g the sleeve to cona fuel prayer in head for delivering fuel into der during the sucton stroke, of
head, an air nlet p end of the cyl'nd gstering Wi der ports, and
the engine and before the air inlet port is In testimqny whereof we have signed our 1 names to ths specification.
BATEMAN DAVID SCOTT.
WILLIAM HENRY TATE.
