Definitions
- This invention relates to internal combustion engines particularly those of the type called two strokes.
- Two stroke engines are well known and it is also well known that they are inefficient, as significant quantities of unburnt fuel are expelled through the exchange port as the compression stroke commences. This comment applies, of course, to the standard open port two stroke engine.
- this invention provides an internal combustion engine, comprising a housing having a cylindrical peripheral portion with an internal ring gear thereon, cylinder block member disposed in said housing and mounted so as to be rotatable therein about the axis of said portion, said cylinder block member including an output shaft extending laterally to one side thereof on said axis, a plurality of cylinders in said cylinder block member radially extending and meeting centrally of said housing to form a common combustion chamber, said cylinder being symmetrically disposed in a plane about the said axis whereby to provide for dynamic balance of the engine in use, spark ignition means for said combustion chamber, and piston in said cylinders each respectively connected to drive a crank in turn driving a gear mating with said ring gear, whereby in use to rotate said cylinder block member and said shaft with respect to said housing; exhaust port means for each cylinder and, for example, poppet valve provides inlet port means for combustible mixture or air for diesel to said common chamber.
- the engine can be fuelled by gas, petrol or petrol/alcohol mixtures, alcohol or diesel fuel.
- Figure 2 is a view of the engine of Figure 1 in the direction of arrow "A" ;
- Figure 3 is a cross-section of the engine looking in the same direction as the view illustrated by Figure 1; and Figure 4 is a cross-section of the engine corresponding to the view shown in Figure 2.
- the engine illustrated generally by 1 is enclosed by housing 2 having a peripheral cylindrical portion 2a with a pair of laterally spaced internal ring gears 2b; bolts 2c fasten the peripheral portion 2a to the side portions of the housing.
- the engine includes an output shaft 3 integral with cylinder block portion 3b in which the combustion cylinders 3a are formed.
- Domed pistons 4 move radially of shaft 3 integral with cylinder block portion 3b in which the combustion cylinders 3a are formed.
- Domed pistons 4 move radially of shaft 3 in the portion 3b.
- Cam 10 mounted on shaft 3 operates a push rod or the like through opening 10a whence to operate a set of breaker points or to trigger an electronic ignition system.
- a poppet valve 12 moving in valve guide 12a provides the inlet for fuel/air mixtures to the combustion chamber, item 17 being a stand pipe through which the combustible mixture is supported.
- Exhaust openings 18 are provided for the exit of combustion products from the cylinders.
- fan scavenging e.g. supercharging or turbocharging (exhaust driven).
- An engine adapted for supercharging has been illustrated; and gear 19, rotatable with shaft 3, provides a take off point for power to drive a blower to charge through pipe 17.
- Flanges 20 enable the engine to be mounted in a vehicle, boat or stationary frame or the like. Note that all pistons move together direction wise (i.e. radially inwardly or outwardly) and in phase, i.e. they all arrive at top dead centre together, providing for a multiple of the compression ratio available for a single cylinder. This enables the engine to have a high compression ratio. By the same token, the converse is true and the power on the power stroke and the B.M.E.P. (brake mean effective pressure) acts on all pistons simultaneously; thus multiplying the equivalent effective torque for the number of cylinders.
- each crankshaft may carry more than one piston, or the block may have more than one set of pistons.
