摘要： A split -cycle aircraft engine includes a crankshaft rotatable about a crankshaft axis. A power piston is slidably received within a power cylinder and is operatively connected to the crankshaft such that the power piston reciprocates through an expansion stroke and an exhaust stroke during a single rotation of the crankshaft. A compression piston is slidably received within a compression cylinder and is operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke during a single, rotation of the crankshaft. A gas crossover passage operatively interconnects the compression cylinder and the power cylinder. An air reservoir is operatively connected to the gas crossover passage by a reservoir passage. The air reservoir is selectively operable to receive and deliver compressed air. The engine is mounted to an aircraft and the air reservoir is disposed within the aircraft.A split -cycle aircraft engine includes a crankshaft rotatable about a crankshaft axis.

摘要： The present invention relates to a method for modifying a petrol-driven, single-cylinder Otto engine, which engine comprises an engine block (1) with a cylinder (2), a cylinder head (3), a piston (4) disposed movably inside the cylinder, two valves (5, 5') arranged by the cylinder, a carburettor (6) with a fuel nozzle (7) and an air filter arrangement (8). The invention is characterized in that the method comprises measuring the existing mimimum play (S1) between the end (5A) of the valve in its extreme position in the open state and the surface (4A; 3A) that faces said end (5A) of the valve, removal of the cylinder head (3), machining of the cylinder head (3), its surface (3B) facing the engine block (1) being cut and levellled by 40-100 % of the existing minimum play (S1) to obtain a considerably smaller modified play (S2) between said valve end (5A) and said opposing surface (4A; 3A), checking that said modified play (S2) does not fall below a certain set value (SB), fitting of the cylinder head (3) and adjustment of the fuel/air admixture so that an increase in the fuel flow in relation to the air flow is achieved, following which the engine has been modified for operation by means of a fuel containing mainly ethanol.

摘要： A multipoint fuel delivery system for an internal combustion engine includes fuel metering device(s) such as fuel injector(s) associated for selectively controlled injection of the second fuel to corresponding combustion chamber(s) of the internal combustion engine. A fuel supply manifold associates with fuel injector(s) for directing the second fuel to each fuel injector. An intake port adaptor mechanism adapts the intake port of the associated combustion chamber to receive the selectively controlled injection of the fuel from an associated fuel injector. The intake port adaptor mechanism may also engage the intake port so as to permit selective flow of the first fuel or the second fuel to the intake port of the selected combustion chamber. A control mechanism selectively controls the flow of the second fuel through each injector(s). The multipoint fuel delivery system make practical both dedicated or single-fuel multipoint injection and, alternatively, selective bi-fuel multipoint injection for an internal combustion engine.

摘要： A series of V type piston engines is made using a common offset (L5) between banks of cylinders and the same V angle, even where big end bearings (21) on a common crankpin (22, 22a) are spaced differently. This is achieved by using a connecting rod offset (L4) for both a V6 and a V8 type engine such that in the V6 the centres (31) of the big end bearings are spaced further apart than the bank offset and in the V8 the centres of the big end bearings are spaced closer than the bank offset.

摘要： Les moteurs à combustion interne conventionnels à injection directe n'allument pas ni brûlent complètement des carburants à indice de cétane relativement bas, tels que l'éthanol ou le méthanol à 100 pour cent, étant donné que le jet pulvérisé de carburant injecté ne peut en général communiquer ou propager une flamme à la totalité du carburant injecté, lequel se compose généralement de courants individuels de carburant séparés par des poches d'air d'admission pauvre en carburant. Le système de combustion de carburant ci-décrit (10) comprend un dispostif de déclenchement d'allumage de carburant (26) tel qu'une bougie à incandescence (70) et un dispositif (98, 102) permettant de relier par contact et d'unir en continu tous les courants individuels de carburant (66) à l'aide d'un nuage auxiliaire (94) de carburant bien atomisé. De cette manière, une flamme déclenchée par le dispositif de déclenchement d'allumage de carburant (26) peut se propager rapidement et complètement par l'intermédiaire du nuage auxiliaire (94) de carburant à tous les courants individuels de carburant (66).

摘要： A four-stroke internal combustion engine (20) is provided. There is provided within an engine housing (28) an oil reservoir (126) and a valve chamber (156) which independently communicate with a crank chamber (124). A strategically placed divider (116) and passageway, located within the engine housing (28), appropriately direct lubricant within the engine housing (28) so that the internal cavity of the engine is lubricated during use in various operating attitudes, and so that the fluid flows to and is held in the proper chambers of the engine housing during storage. There is also provided a breather arrangement for an internal combustion engine (20) which includes a cam shaft (98) having a hollow passageway in communication with the crank chamber (124) and the air intake system of the engine. There is also provided an engine housing which can be utilized for engines having different horse power ratings. There is also provided a crankshaft bearing assembly (68, 70) which prevents damage to the bearing upon insertion of the crankshaft (80) into the crank chamber (124).

摘要： The present invention relates to an engine and a method for producing the engine.
The engine is constructed as follows.
The engine interlockingly operates a pump (39, 139) for feeding fuel under pressure, by power of a crank shaft (1). A pair of gears (32a) and (32b) are arranged to be attached to a gear attaching shaft (32). The paired gears (32a) and (32b) are attached to the gear attaching shaft (32). At least one gear (32a) of the paired gears (32a) and (32b) constitutes a gear train (14, 114) through which the power of the crank shaft (1) is transmitted to the pump (39, 139).
The method for producing the engine is constructed as follows.
The method uses a common part for each of the gear trains (14) and (114) so as to produce engines of an injection pump specification and a common rail .specification and alternatively manufactures the gear trains (14) and (114) through the common part. It comprises attaching a pair of gears (32a) and (32b) to a gear attaching shaft (32) of the engine of every specification, making one gear (32a) of the paired gears (32a) and (32b) serve as a basic gear and the other gear (32b) serve as a second gear, employing the basic gear (32a) as the common part for each of the gear trains (14) and (114) and alternatively manufactures the gear trains (14) and (114) of the engines of the respective specifications through the basic gear (32a) of the common part.

摘要： The invention relates to a method for the operation of a steam thermal engine, whereby the hot steam from a working medium is converted into kinetic energy, by means of a pressure-releasing device (1). The working medium is heated in a boiler (6) to a low temperature, preferably boiling point at a low pressure, steam is taken from the boiler (6) to a pressure chamber (7, 8), in which the steam is heated to a higher temperature. Liquid working medium (or condensate) is injected from the boiler (6) into the pressure chamber (7, 8) whereupon the working medium is instantaneously evaporated, such that the pressure in the pressure chamber (7, 8) rises markedly and the steam is fed from the pressure chamber (7, 8) to the pressure-releasing device (1).
