Abstract: A forced-induction device includes a turbine wheel, a turbine housing, and a connection pipe. The connection pipe includes a partition wall that partitions the inside of the connection pipe into a first passage and a second passage. When a cross section orthogonal to a rotation axis of the turbine wheel is viewed, a line segment extending from the distal end of the partition wall toward the upstream side in the flow direction of exhaust gas and defining a boundary between the first passage and the partition wall is a first downstream line segment. A line segment extending from the distal end of the partition wall toward the upstream side in the flow direction of exhaust gas and defining a boundary between the second passage and the partition wall is a second downstream line segment. The first downstream line segment and the second downstream line segment are parallel to each other.

Abstract: An engine air-fuel ratio control system is configured to use a rich air-fuel ratio immediately after starting an engine such that the air-fuel ratio converge rapidly toward a stoichiometric value and then afterwards start an air-fuel ratio feedback control. Upon determining an air-fuel ratio sensor is active, a stabilization fuel quantity increasing factor that is a component of a target air-fuel ratio revising coefficient is decreased at a higher rate than the rate used before the air-fuel ratio sensor was determined to be active. Air-fuel ratio feedback control is started when the air-fuel ratio corresponds to a stoichiometric air-fuel ratio. After starting air-fuel ratio feedback control, an unburned fuel quantity compensating value is set based on the stabilization fuel quantity increasing factor in effect at that point in time and added to the target air-fuel ratio revising coefficient while, simultaneously, the stabilization fuel quantity increasing factor is set to zero.

Abstract: The invention is directed to a method for operating an internal combustion engine such as for a motor vehicle. Regeneration gas is added for only a short time duration (T) to air inducted into the combustion chamber of the engine and fuel is injected directly into the combustion chamber. The fuel and regeneration gas are combusted in the combustion chamber and a specific behavior of the combustion of the fuel and the regeneration gas is assumed. The actual combustion behavior of the fuel and the regeneration gas is detected and the hydrocarbon concentration of the regeneration gas is determined from the assumed specific behavior and the detected behavior. Fuel is injected into the combustion chamber during the next time duration (T) for an injection time (TI) dependent upon the hydrocarbon concentration.

Abstract: A cylinder body has a bore and an annular recess in communication with the bore. A piston is mounted for reciprocation within the bore, the piston having an annular skirt which reciprocates within the recess. A connecting rod has one end pivotally connected to the piston and the opposite end pivotally connected to a crankshaft for turning movement about an axis. A drive roller is rotatably carried by the crankshaft for turning movement about an axis. The drive roller is disposed in a cam groove in a flywheel which is drivingly connected to an output shaft. The two axes oscillate along two parallel arcs during reciprocation of the piston.

Abstract: A cylinder liner support arrangement in an internal combustion engine, preferably in which the cylinder block and cylinder head are integrated in a common monobloc element and the cylinder barrels for the engine pistons have cylinder liners which have their upper portions inserted in cylinder bores in the cylinder block. The lower portions of the cylinder liners are accommodated in cylindrical apertures in a common cylinder liner support which may be made as a single element and is removably secured to a lower surface of the cylinder block. The cylinder liner support includes a number (corresponding to the number of cylinders of the engine) of mutually connected supporting sleeves which are disposed in-line, delineate the cylindrical apertures and have their sleeve walls surrounding the lower portions of the cylinder liners and providing them with lateral support. The cylinder liner support includes a mounting plate from one side of which the supporting sleeves protrude. Along the side edges of the mounting plate fastening holes are provided to accommodate screws for screwing the cylinder liner support securely to the lower surface of the cylinder block.

Abstract: Improved heat insulating of a combustion chamber in an internal combustion engine is obtained by providing a heat-resistant body in at least one surface, which is intended to at least partly limit a combustion chamber. A support body supports the heat-resistant body, said bodies each having facing mantle surfaces. Between said bodies there is a heat-insulating element of a material having a lower coefficient of thermal expansion and a lower modulus of elasticity than the material in either one of said bodies. The bodies and the element are held together at the mantle surfaces by means of a shrink fit.

Abstract: For the more efficient operation of both spark- and compression-ignited internal combustion engines, and/or control of octane requirement increase in spark-ignited internal combustion engines, at least a portion of the surfaces of the intake manifold exposed to the fuel-air mixture, and/or the combustion chamber exposed to combustion, are fabricated from coated with a material having the combination of thermal conductance and thermal penetration which permits the temperature of said surface during the combustion process to be in excess of the temperature at which deposits form and said surface storing insufficient heat to substantially raise the temperature of the incoming air-fuel charge during the engine intake and compression stroke.
