Abstract:
A hydraulic valve lifter for an automotive internal combustion engine, having a lifter cylinder formed with a first cylinder chamber contractable in response to a force exerted on the lifter from the cam on the engine camshaft and a second cylinder chamber contractable between a zero volume condition and a maximum volume condition in response to variation in the engine oil directed into the lifter, whereby the valve timings and valve lift are varied with the engine-oil-pump pressure that varies with engine speed.
Abstract:
A plurality of pump elements is progressively increasing the pressure of air to respectively supply air at various pressures into portions in an exhaust gas purifying system requiring secondary air.
Abstract:
A light emitting element having a light emitting layer, an electro-conductive reflection film that reflects light emitted from the light emitting layer and a substrate in this order, wherein the electro-conductive reflection film contains metal nanoparticles.
Abstract:
An object of the invention is to provide a rubber modified asphalt type of waterproofing composition which can be used in a normal temperature type of spray waterproofing method and can find its application in waterproofing, moisture-proofing, rustproofing, and filling buildings and structure for engineering works, said waterproofing composition coagulates instantaneously to form a stable yet firm waterproofing layer. This rubber modified asphalt type of waterproofing composition comprises a cationic rubber modified asphalt emulsion and an organic coagulating agent.
Abstract:
Herein disclosed is a power plant structure which generally includes an engine part and a transmission part. In order to increase the rigidity of the power plant structure, the cylinder block of the engine is tightly connected by bolts to a mounting portion integrally formed on a transmission case. For more assured rigidity, a ladder beam structure is tightly disposed between the cylinder block and the mounting portion.
Abstract:
The cooling circuit of an internal combustion engine cooling system wherein the coolant is allowed to boil and the vapor used as a vehicle for removing heat from said engine is equipped with an external reservoir and arranged so that the amount of liquid coolant in the cooling circuit of the system can be varied in a manner which both assists in controlling the boiling point of the coolant and prevents the development of negative pressures which invite the invasion of non-condensible matter such as atmospheric air.
Abstract:
In order to accurately detect the coolant level in the coolant jacket of a cylinder head, a separate chamber member is mounted to the cylinder head and fluidly communicated with the coolant jacket of the cylinder head in a manner to contain therein the coolant by the same level as that in the coolant jacket, and a level sensor is mounted to the chamber member to detect the level of coolant contained in the chamber member.
Abstract:
A small capacity pump continuously driven by a mechanical connection with the crankshaft or the like of the engine, is arranged to induct coolant from both the radiator wherein the coolant vapor is condensed to its liquid state and a liquid/vapor separator disposed in the vapor transfer conduit via which the coolant vapor is conveyed to the radiator from the coolant jacket. In order to maintain the cylinder head exhaust valves and ports immersed in a predetermined depth of liquid coolant a level sensor is disposed in the coolant jacket and the output used to open and close a valve fluidly interposed between the radiator and the pump. If required a second valve can be interposed between the pump and the separator and arranged to be closed when the first one is open.
Abstract:
In a boiling liquid engine cooling system which employs an electric fan for increasing the condensation function of a radiator (or condenser), there is employed a control means which restrains the rotation speed of the electric fan to a low level at the beginning of the fan rotation and thereafter gradually increases the rotation speed to the normal level as the time proceeds. With this, undesirable sudden violent boiling of liquid coolant in the coolant jacket is prevented.
Abstract:
In an internal combustion engine cooling system wherein the coolant is boiled and the vapor produced condensed in a radiator in a manner that the rate of condensation under light engine load is maintained at a level sufficiently low to raise the pressure within the system and thus raise the boiling point of the coolant while under heavy load increased to the point of lowering the pressure in the system and thus lower the coolant boiling point, a reservoir/valve arrangement is provided which permits additional coolant to be inducted into the system, in the event that an excessively low or negative pressure occurs (due to uncontrollable external influences), under the influence of the pressure differential which is established between the ambient atmosphere and the interior of the system. The coolant thus inducted is permitted to be displaced back out to the reservoir only when the temperature and pressure in the system is restored to the desired level.
