Abstract: The disclosure relates to a novel arrangement of a combustion chamber for diesel engines, which is defined by an inner wall including a fuel-impinging area formed of a metallic material, and a remaining area which at least partly is formed of a ceramic material or a like heat-resisting material. The arrangement serves to achieve an effective exhaust gas clarification, including the minimization of NOx emission, and to realize increased power output and reduced fuel consumption of the engine.

Abstract: An engine control valve is disclosed which comprises a first bypass passage for introducing auxiliary air flow to an engine from an upstream side of an intake throttle valve disposed in an air intake pipe of the engine while bypassing the intake throttle valve; a second bypass passage having an inlet port in communication with an outlet port of the first bypass passage, for introducing the auxiliary air flow, introduced through the inlet port, to a downstream side of the intake throttle valve; a valve body for changing an opening area of at least one of the outlet port of the first bypass passage and the inlet port of the second bypass passage, thereby adjusting an amount of the auxiliary air flow to be introduced from the upstream side to the downstream side of the intake throttle valve; and a drive unit for driving the valve body in accordance with a drive signal outputted from the control unit. When a maximum drive signal is inputted into the drive unit, the opening area of at least one of the outlet port of the first bypass passage and the inlet port of the second bypass passage is throttled so that a predetermined amount of the auxiliary air flow smaller than a maximum amount of the auxiliary air flow may be introduced into the downstream side of the intake throttle valve.

Abstract: A pump has in a housing a revolvable shaft which drives a piston stroke guide body. Drive pistons are provided with piston shoes which run on the guide face of the piston stroke guide body and drive fluid supply pistons of smaller diameter. The pump preferably has a fluid separator between lubricating and non-lubricating fluid, like for example between oil and water, whereof one of the fluids flows through an inner chamber which is provided with inlet and outlet valves while the other fluid acts in an outer chamber which is open toward the cylinder wherein the fluid supply piston reciprocates. Dead space fillers are provided to prevent losses by compression of fluid and seal means are assembled to prevent leakage of fluid from one into the other of the chambers. The fluid separator may be compressible and expandable within the elasticaly deformable range of the material whereof it is made. The pump includes sophisticated tenchologies which necessiated more than half a decade of intensive research and testing but it is now capable of pumping fluid, including water, of several thousand atmospheres of pressure.

Abstract: A piston of a light alloy matrix material having a cavity for containing heat insulating air immediately below its head or a cavity for passing cooling oil inside the grooved side wall is manufactured by preforming a precursory member having the shape of the cavity from an extractable material which remains in solid state at room temperature and is convertible into a fluid, gas or liquid when heated at a temperature below the melting point of the matrix metal. The precursory member is disposed in place in a pressure casting mold having a cavity corresponding to the shape of the piston, and covered with a porous member stable to the molten matrix metal. A head member of heat resisting metal material to constitute at least a portion of the piston head may be disposed on the mold cavity bottom. Molten matrix metal is then cast into the mold cavity and a pressure is applied thereto to form a piston-shaped casting having precursory member and porous member embedded therein. Finally the casting is heated at a sufficient temperature to gasify or liquefy the extractable material of the precursory member material into fluid, which is extracted from the casting, leaving a cavity at the location of the precursory member. Alternatively, the precursory member may be formed from a composite material of a gasifiable material and a stable material whereby the cavity is given as a porous insert of the stable material which is left after the extraction of the gasifiable material by heating.

Abstract: A composite thermal shield includes an external solid layer of heat and corrosion-resistant metal bonded to a permeable layer of metal. The composite is mechanically affixed to the substrate metal of an engine component, by a method wherein the substrate metal becomes entrained within the interstices of the permeable metal layer. In a first preferred form the permeable metal layer is comprised of a fibrous stainless steel woven wire mesh which is sintered or brazed to the external stainless steel heat and corrosion-resistant layer. In a preferred process, an aluminum substrate piston is formed to include the composite shield, whereby the aluminum is pressed into the permeable layer during formation of the piston in a mold. In a second preferred form, the piston includes an insulation layer wherein two layers of stainless steel wire mesh have an intermediate stainless steel layer sandwiched between them. The bottom layer of wire mesh is subjected to the afore-described mechanical bonding with the substrate aluminum, while the upper layer, positioned between the top and intermediate stainless steel layers, operates purely as an insulation layer.

Abstract: In radial bearings of mechanical nature the life time id is limited. In hydrostatic bearings the lateral loads may over time or even quickly deform the bearing and make it less effective. The invention overcomes this problem by providing not a hydrostatic bearing, but mechanical bearings to revolvable members and a hydrostatic support member, which carries the major portion of the load. The hydrostatic support member is radially flexibly mounted in order to adapt itself for proper support of the mechanical bearings. The device is also very convenient for hydrostatic pumps and motors with radially expanding and contracting working chambers.

The extremely rich air-fuel mixture is introduced into the first auxiliary chamber and a combustible mixture is formed in the first auxiliary chamber. The combustible mixture is ignited and a burning gas is injected into the main combustion chamber. A part of the burning gas is introduced into the second auxiliary chamber and, as a result, the extremely rich air-fuel mixture in the second auxiliary chamber is pushed out into the main combustion chamber. The entire extremely rich air-fuel mixture is burned in the main combustion chamber.
