摘要:
In the case of a multi-cylinder reciprocating engine in a V-construction, the crankshaft drives the camshafts and an output shaft to the clutch in a center plane of the engine by means of gear drives. The crankshaft, also by means of gear drives, drives two identically designed pump units comprising a water pump and oil pumps which are mounted on the outside on the crankcase, symmetrically to the center plane of the engine.

In the case of a reciprocating engine of V-construction, a generator is arranged in the V-center. The outer walls of the engine power section bounding the V-cutout are adapted to the cylindrical housing of the generator and surround it at a radial distance.

A lubricating arrangement attached end face at the engine housing of a reciprocating piston engine is surrounded by an oil pump housing which is composed of two housing parts cast of magnesium. The oil pumps are preassemblable in the oil pump housing. The couplings of the oil pumps and the lubricating connections are so constructed that the oil pump housing is easily assemblable at the engine housing as a structural unit.

A one-piece cylinder block for a water-cooled internal combustion engine with two rows of cylinders in a V-arrangement has a longitudinal duct for supplying cooling water. The block is preferably made by a diecasting process. The longitudinal duct is connected to the coolant spaces of the cylinders which are located between a cylinder sleeve and an outer jacket surrounding the latter. The longitudinal duct is disposed between the rows of cylinders in the cylinder block and at least one opening is provided in the region of the coolant spaces for each cylinder. These openings are cast in the casing walls of the cylinder block. Since they are disposed directly adjacent the longitudinal duct, they extend essentially radially to the cylinders.

A water pump for a reciprocating piston internal combustion engine is driven by a shaft located between the camshaft and crankshaft. The intermediate shaft which is driven by and coupled to the crankshaft at one wall of the crank housing. The water pump is located in a remote wall of the crank housing, which itself forms one half of the pump containment. A dish-shaped housing half screws into the remote wall to contain the pump. The intermediate shaft is connected to the pump wheel of the water pump by a hollow shaft which passes longitudinally through the crank housing. Together with the bearings, securing elements, sealing rings and a bearing flange, the shaft forms a structural unit which may be pre-assembled and easily inserted into the engine.

For avoiding exterior, cooling-water-carrying ducts, an internal-combustion engine comprising two mutually opposite cylinder banks has integrated ducts for the feeding and removal of the cooling water to the cooling jackets and the cylinder heads.
摘要:
A reciprocating engine has two cylinder banks arranged in a V-shape and a grear drive which originates from the crankshaft and leads to a drive shaft connected with the clutch as well as to camshafts and liquid pumps for cooling water and lubricating oil of the engine. The gear drive is designed such that the crankshaft, the camshafts and liquid pumps rotate in one rotating direction, and the output shaft and the clutch rotate in the other rotating direction.
摘要:
An apparatus and method for operating a piston driven internal combustion engine having an exhaust gas turbocharger, provides for the exhaust gases of the cylinders to be conducted to an afterburner chamber and subsequently to the exhaust gas turbine of the turbocharger when the motor vehicle is coasting, i.e., when the motor vehicle and engine are being driven by the vehicle's inertia, with the ignition for the cylinders being turned off and the charging air being introduced into the afterburner chamber. The noncombusted fuel/air mixture from the cylinders is combusted in the afterburner chamber with the additional charging air to thereby bring the turbocharger to its full output for reacceleration of the engine.

A supercharged internal combustion engine of the type having an exhaust gas turbine driven supercharging blower, exhaust gas bypass for regulating the exhaust gas turbine by diverting exhaust gases around the turbine, and a blow-off valve control charging air bypass for circulating charging air supplied from the blower therearound when an engine performance control member such as a throttle is closed, is improved by provision of a second charging air bypass for circulating a portion of the air supplied by the blower therearound in response to at least one operating parameter of the engine in a manner so as to provide protection against excess charging pressure. The at least one operating parameter for controlling the second bypass includes engine rpm and/or charge pressure and opening of the second bypass may be regulated by a solenoid valve controlled by a safety switch responsive to charging air pressure or an rpm transducer such as an ignition pulse transducer.
摘要:
A fuel-exchange poppet valve of a reciprocating internal-combustion engine is actuated by two electromagnets that, in an alternating way, are energized periodically to attract an armature disk arranged between them. The armature disk is fastened at an armature that is coupled to a one-armed fuel-exchange poppet valve control lever. The control lever is pivotally moved back and forth against the spring tension of a torsional bar spring to open and close a poppet valve.
