Abstract: A cross-flow type internal combustion engine having an exhaust gas recirculating passage formed in the cylinder head. The passage is located adjacent to cooling water jackets so that the gas in the passage is cooled by the water in the jackets. The passage is formed with an expansion chamber which is also located adjacent to the cooling water jackets and the intake ports. Due to the cooling effect in the passage, water content in the recirculated gas is condensed and separated from the gas. Further, the gas flow speed is decreased in the expansion chamber so that carbon particles in the recirculated gas can be separated therefrom.

Abstract: Rotary piston engine having a main intake port in one side housing of the casing. The side housing is further formed with a supercharging air port which is connected with a supercharging passage leading from an air pump. The supercharging air port is so formed that it is opened substantially simultaneously with and closed later than the main intake port. A control valve may be provided in the supercharging passage to open the passage when the main intake port is substantially closed.

Abstract: Rotary piston engine having a main intake port in one side housing of the casing. The side housing is further formed with a supercharging air port which is connected with a supercharging passage leading from an air pump. The supercharging air port is so formed that it is opened substantially simultaneously with and closed later than the main intake port. A timing valve is provided in the supercharging passage to open the passage cyclically so that the supercharging is performed at the end period of the intake stroke. A centrifugal device controls the valve timing so that the valve timing is advanced under an increased engine speed.

Abstract: Panel reinforcement structure for automobile bodies including a wide outer skin such as a roof panel, a bonnet and a trunk lid, and one or more reinforcement members for applying the skin with a rigidity. The reinforcement member is applied to the outer skin with one or more layers of a mastic sealant. A layer of open cell type elastic foamed material is provided between the mastic sealant layer and one or each of the outer skin and the reinforcement member for the purpose of allowing a relative movement between the outer skin and the reinforcement member to avoid any distortion of the outer skin due to a difference in thermal expansion.

Abstract: Sliding-roof type sun-roof structure for automobile bodies comprising an opening formed in the roof panel and a sliding roof adapted for closing the opening. guide rail assembly is provided for guiding the sliding roof from the closing position to a retracted position wherein it is retracted under the roof panel. The guide rail assembly includes a front and rear sections which are connected in an articulated manner. The guide rail assembly is interconnected with the movement of the sliding roof so that it is downwardly bent at the articular connection when the sliding roof is being moved but maintained in a raised position when the sliding roof is in the closing and retracted positions so as to provide an increased overhead space.

Abstract: A multiple cylinder engine having an intake passage for each cylinder. A shut-off valve or valves are provided in the intake passage or passages leading to selected one or ones of cylinders downstream of the throttle valve. The shut-off valve is closed in idling operation so that the combustible mixture is totally supplied to the remainder of the cylinders to increase the mixture charge therein. The intake passage or passages leading to the selected cylinder or cylinders are supplied with air when the shut-off valves are closed so that the peak pressure in such cylinders is increased. The air supply is cut-off in deceleration in order for preventing the engine-brake effect from being weakened.

Abstract: A heated fuel intake system for an internal combustion engine for introducing warmed air to the engine and air to a fuel supply circuit in a carburetor comprises a heat stove from which the warmed air is introduced into an air cleaner to heat the air to a temperature equal to or higher than a first predetermined temperature. The introduction of the warmed air from the heat stove is interrupted by a first valve unit when the temperature of the air to be fed to the engine has exceeded the temperature equal to or higher than the first predetermined temperature. The introduction of the warmed air into the air cleaner is again initiated when the temperature of the air inside the air cleaner becomes a value equal to a second predetermined temperature higher than the first predetermined temperature and, simultaneously therewith, an air-fuel ratio leaner is operated to introduce an additional air to compensate for the increased richness of the combustible mixture.
