摘要： PURPOSE:To accelerate the swirling speed of suction gas to be fed into an aux. combustion chamber under the compression stroke by providing the oversurface of a piston with a boss which is to squeeze the open area of a pipeline in the neighborhood of the upper dead point, wherein the pipeline couples the aux. combustion chamber with the cylinder inside. CONSTITUTION:A two-cycle Diesel engine with aux. combustion chamber, in which suction gas in the form of circumferential swirling stream is sucked into a cylinder 1 from a suction port 13 opening near the lower dead point, is equipped with a pipeline to couple the aux. combustion chamber 2 with the cylinder 1 inside and an exhaust port to discharge the gas by an exhaust valve 24 installed at the aux. combustion chamber 2. A boss 31 to squeeze the pipeline near the upper dead point is furnished on the oversurface of piston 3. Thereby the swirling speed of suction gas to be fed into the aux. combustion chamber 2 is accelerated under the compression stroke, while under the scavenging stroke the fluid resistance from inside the cylinder 1 to the aux. combustion chamber 2 side is lessened. This enhances the engine efficiency and decreases the rate of fuel consumption, and also high-speed operation becomes practicable because scavenge is made quickly.

摘要： PURPOSE:To improve output by forming a main port and a sub-port as scavenging ports of a 2-cycle engine on the peripheral side wall of a cylinder, providing a switch valve on the sub-port, and controlling the switch valve to open and close according to engine revolving speed and load. CONSTITUTION:In the case of applying the titled device to a cycle Diesel engine, a main port 1, a sub-port 2 for low speed and a sub-port 3 for high speed are provided as scavenging ports, and a switch valve 4 is disposed on each of the sub-ports 2, 3. Exhaust ports 5-8 are formed on a cylinder head 9. The main port 1 and the sub-ports 2 for low speed care formed at positions substantially point-symmetrical about the center of a cylinder, and swirl 11 by the sub-port 12 for low speed can be generated in the direction of furthering swirl 10 by the main port 1. The main port 1 and the sub-port 3 for high speed are positioned opposite to each other, and swirl 12 by the sub-port 3 for high speed can be generated in direction of obstructing the swirl 10 by the main port 1.

摘要： PURPOSE:To restrain torque fluctuation caused by engine explosion, by making an alternator generate power in increasing torque generated in a crank-shaft to generate reverse torque in the crank-shaft. CONSTITUTION:A timing detecting means 3 is constituted from a crank angle sensor 7 for generating detecting signals when pistons in respective cylinders are in the upper dead point positions and a wave shaping circuit 8 so that torque increasing time in rotational torque fluctuation can be detected. The output of the detecting means 3 is supplied to the input of a single multiplexer 9 of a field current control to provide signals having pulse width corresponding to time in which field current is applied, and these signals are applied to a field coil 1a of an alternator 1 through a drive circuit 10. Namely, in the increase of torque, current is supplied to the field coil 1a to cause the alternator 1 to generate electricity so that reverse torque is generated in a crank-shaft to restrain the fluctuation of rotational torque.
摘要翻译：目的：为了抑制发动机爆炸引起的扭矩波动，通过使曲轴产生的扭矩增大，使交流发电机发电，产生曲轴转矩。构成：定时检测装置3由用于在各个气缸中的活塞处于上死点位置时产生检测信号的曲柄角传感器7和能够检测转矩变动中的扭矩增加时间的波形整形电路8构成。检测装置3的输出被提供给励磁电流控制的单个多路复用器9的输入，以提供具有对应于施加励磁电流的时间的脉冲宽度的信号，并将这些信号施加到交流发电机1通过驱动电路10.也就是说，在转矩的增加中，向励磁线圈1a供给电流，使交流发电机1产生电力，从而在曲柄轴上产生反向转矩，以抑制转矩的波动。
