An internal combustion engine wherein a combustion chamber is formed by moveably fitting a bottomed tubular moveable sleeve on a stationary piston in which a valve mechanism is incorporated, and the moveable sleeve is connected to a crankshaft via a connecting rod.

With reference to FIG. 1, the present invention relates to an internal combustion engine comprising: a combustion chamber (10); first (A) and second (B) inlet valves controlling flow of air into the combustion chamber, first (C) and second (D) exhaust valves; and first (16) and second (18) turbochargers. The first turbocharger (16) is connected to the first inlet valve (A) and the second turbocharger (18) is connected to the second inlet valve (B). The first turbocharger (16) is connected to the...

An internal combustion engine controller has: a voltage booster circuit for boosting a battery power source; a booster side driver element for flowing a current through the injectors by using the boosted voltage; a battery side driver element disposed in parallel with the booster side driver element to flow a current through the injectors by using the battery power source; a first downstream side driver element provided by controlling currents flowing through the injectors; current regeneration ...

Disclosed is a piston (1) for a combustion engine, comprising an annular grooved reinforcement (4) that is screwed onto an externally threaded (13) collar (12) located in the piston head area via an internal thread (19) which is mounted on the inside of the grooved reinforcement (4). The grooved reinforcement (4) blocks a recess (14) so as to form an annular, closed cooling duct (21). In order to provide the screwed connection between the collar (12) and the grooved reinforcement (4) with suffic...

In a shoe drum brake a mechanical actuator for separating adjacent shoe ends includes a lever pivotally connected to a shoe and adapted to act on the other shoe through a strut which is chordal with respect to the axis of the brake. In the off position of brake the lever is held in a first retracted position spaced from a fully retracted position by a back stop. The back stop is adapted to be manipulated externally of the brake to permit the lever to move into the fully retracted position under ...

The carburetor has a fuel/air mixture supply circuit constituted by the sequence of an ascending channel connected to a float chamber through an immersed calibrated orifice and a descending channel with an opening into the intake pipe of the carburetor downstream of the main throttle member of this pipe. The descending channel is controlled by a member which opens it only during periods of deceleration of the engine. The linking zone between the two channels is above the constant level of the fl...

The disclosure herein is directed to valving means of the type commonly used in highway and railway tank cars. The operating mechanism of the valve is positioned within the tank with only the actuator of the valve projecting beyond the tank surface. Accordingly, in the event of a wreck or the like, the valve will not be damaged. The valve, comprising a ball positioned in a body portion between a pair of resilient lip seals, is conveniently actuated from a side thereof or from the bottom by means...

This disclosure relates to methods for nucleating castings to control their grain formation and teaches the addition of a slug of solid material to the superheated melt shortly before pouring for the purpose of forming and maintaining crystalline dendrite fragments in the melt during and after it has been poured into the mold.

A transmission in which the input and output shafts are coupled by a fluid drive which is pressurized by eccentrically driven pumps, the variable speed fluid coupling being effective until a particular rotational speed is reached, at which speed the drive is positively locked. Means is also provided for locking the driven selectively at any speed. The transmission can be shifted between forward and reverse positions, and the shift mechanism incorporates braking means to facilitate gear engagemen...

A reactor for purifying exhaust gas in an exhaust gas system of an internal combustion engine comprises an inner shell forming a reaction chamber and an outer shell surrounding the inner shell and defining an adiabatic zone therebetween. A pipe member extends through the outer shell to the inner shell for absorbing the heat expansion of the inner shell. The pipe member disposed for movement in the axial direction and in the direction normal to the axis of the pipe member relative to the outer sh...
