    • A method of increasing the fatigue strength of crankshafts for reciprocating engines, especially internal combustion engines, is provided. When converting naturally aspirating production engines to supercharging to increase the power, the fatigue strength of the crankshaft quickly reaches a limit. Since for reasons of economy it is desirable not to alter the geometry of the crackshaft and to avoid expensive fine burnishing to increase the quality of the surface, and hence the fatigue strength associated therewith, the transition radius from the crankshaft pin to the crank web is inductively surface hardened, and at the same time the finish quality of the surface is reduced. The increased costs for the hardening are balanced by the reduced surface machining that is required.

    • A cross-section controlled multi-jet injection valve for an air-distributor injection in air-compressing combustion engines is provided. In order to fulfill the more stringent requirements and standards for exhaust fume quality it is necessary to provide a homogenous fuel/air mixture. This is achieved with a valve needle which is provided with an axially and radially oriented key. Due to this key a favorable ratio of injection cross-section to circumference of the respective cross-section is achieved. Accordingly, a division of the injection jet and a mixing with air is provided. Due to correspondingly adjusted pressure springs the injection pressure at varying amounts of fuel to be injected is kept constant which furthermore provides a constant homogeneity of the fuel/air mixture. Thus an excellent exhaust fume quality is obtained for the entire performance range.

    • The present invention relates to an injection system for air-compressing combustion engines. In order to reduce the combustion noise of diesel combustion engines it has been suggested to divide the injection step into a pre-injection and main injection. In order to improve the velocity of the injection quantity increase during partial load and/or at low revolutions per minute it is suggested that a pressure wave generator is arranged downstream of the injection pump and to further provide a volume reservoir in parallel to the pressure wave generator. The pressure wave generator ensures that the passage of the injection line is opened only when a predetermined pressure has been reached. After opening of the pressure wave generator the pressure will not drop as quickly since fuel will be supplied by the volume reservoir even when the injection pump has only a low piston velocity. A further advantage of the present invention is that the by-pass line may branch off at a metering piston unit so that due to the reflection of the pressure wave at the metering piston, generated by the pressure wave generator, a doubling of the pressure occurs.
    • 本发明涉及一种用于空气压缩内燃机的喷射系统。 为了降低柴油机内燃机的燃烧噪音,建议将喷射步骤分为预喷射和主喷射。 为了提高在部分负载和/或每分钟低转速期间喷射量增加的速度,建议将压力波发生器布置在喷射泵的下游,并进一步提供与压力波平行的容积储存器 发电机。 压力波发生器确保仅在达到预定压力时打开注入管线的通道。 在打开压力波发生器之后,即使当注射泵仅具有低的活塞速度时,由于燃料将被容积储存器供应,压力也不会快速下降。 本发明的另一个优点是,旁路管线可以在计量活塞单元处分支,使得由于由压力波发生器产生的计量活塞处的压力波的反射,发生压力加倍 。

    • A level control system for an omnibus, especially a low-loading omnibus, having an omnibus body supported on axles and wheel suspension, is comprised of a compressed air system that is self-contained for each axle. The following vertical adjustments are possible: during a stop of the omnibus at a bus stop, the omnibus body is pivoted about a longitudinal median floor level axis for lowering the omnibus body at a passenger boarding side and the opposite side is raised by internally pumping the compressed air from the pneumatic springs of the boarding side to the pneumatic springs on the opposite side at each axle. After the completion of the stop at the bus stop, the compressed air is returned to the pneumatic springs on the boarding side so that the omnibus resumes its normal position. In this manner, the compressed air is kept in a self-contained system and is not lost to the atmosphere. Accordingly, there is no need to provide further compressed air to the system, thus reducing the amount of energy required for operating such a system; the power necessary for the internal pumping or transfer of the compressed air is small in comparison.

    • A method and apparatus for decelerating a marine propulsion system during an emergency stop maneuver is provided. In order to achieve a faster reversal of the direction of rotation of a propeller shaft an engine brake is activated before switching the three shaft birotatory reduction gear system in order to decelerate the engaged and rotating gear system parts effectively. Only when the rotation of the gear system parts has been reduced to a predetermined number of revolutions the gear system is switched to the reversed direction of rotation by a control switch on the bridge so that the propeller shaft is rotating in the reversed direction of rotation and subsequently the number of revolutions of the combustion engine is increased to full load. The emergency stop maneuver may be performed in a very short period of time with the proposed method. The apparatus comprises a motor brake having a throttle valve eccentrically supported in the exhaust pipe of the combustion engine.

    • An outlet valve lifter for internal combustion engine is described. In order to increase the braking power of the internal combustion engine it is necessary that the outlet valve is opened during the compression cycle. Advantageously, this is achieved by a hydraulic outlet valve lifter which is actuated by an external pressure source. Due to the pressure of the compressed air shortly before the ignition top dead center position great forces are acting on the outlet valve and accordingly on the outlet valve lifter. These forces, in the form of hydraulic pressure, act via the inner portion of the outlet valve lifter on the external pressure source and may cause damage. Therefore, the outlet valve lifter is provided with an inner portion which is lifted by a certain stroke due to the pressure actuation via a second pressure chamber so that the outlet valve opens. When the pressure within the second pressure chamber increases as a function of the forces acting on the outlet valve and surpasses the hydraulic pressure generated by the external pressure source, a ball valve closes the second pressure chamber so that the hydraulic pressure generated therein may not be transmitted to the external pressure source.
    • 描述了用于内燃机的出气阀提升器。 为了增加内燃机的制动功率,需要在压缩循环期间打开出口阀。 有利地,这通过由外部压力源致动的液压出口阀提升器来实现。 由于压缩空气的压力在点火之前不久,上止点位置,大的力作用在出口阀上,因此作用在出口阀升降器上。 这些力以液压的形式通过外部压力源上的出口阀提升器的内部部分作用,并可能造成损坏。 因此,出气阀提升器具有内部,该内部部分由于经由第二压力室的压力致动而被提升一定行程,从而使出口阀打开。 当第二压力室内的压力作为作用在出口阀上的力的函数而增加并超过由外部压力源产生的液压时,球阀关闭第二压力室,使得其中产生的液压不可能 传输到外部压力源。

    • A motor brake for an air-compressing internal combustion engine is provided. A hydraulic linkage system is disposed between a cam and an exhaust valve, and communicates via a connecting line with a high-speed solenoid valve and a linkage oil compensating system of an engine lubricating-oil circuit. A control valve is disposed in an exhaust manifold of the engine and upon actuation of the motor brake partially closes off the exhaust manifold along with activation of the solenoid valve. Via the interposition of a control unit, signals of at least one sensor are conveyed to a solenoid of the solenoid valve in such a way that, upon actuation of the motor brake during a specific time interval during lifting of a valve tappet via a projection of the cam in a compression phase, the solenoid valve is closed. The time interval is derived via processing of signals of the sensor formed from the cam position and camshaft speed. The cam is divided into six sectors having a first angular range for opening the exhaust valve in an exhaust phase, a second angular range for filling a cylinder space of the valve tappet, a third angular range for initiating closure of the solenoid valve, a fourth angular range for the cam projection, a fifth angular range for reopening the solenoid valve, and a sixth angular range for emptying the cylinder space.
