摘要： To smoothly introduce intake air or mixture through at least one intake valve and exhaust combustion gas through at least exhaust valve, an intake side conical wall surface is formed in an inner wall of the cylinder head in smooth continuous connection with a conical surface formed at an end of the intake valve seat, and an exhaust side conical wall surface is also formed in the inner wall of the cylinder head in smooth continuous connection with a conical surface formed at an end surface of the exhaust valve seat. It is preferable not to allow liquid fuel introduced through the intake to flow directly toward an ignition plug provided at the center of the cylinder, but to allow the introduced liquid fuel to flow directly toward the exhaust port along a flat surface, recess, groove, guide surface, etc. formed around the ignition plug for prevention of misfiring. Further, it is preferable to form a recess on a top surface of the piston, project the ignition plug from inner surface of the cylinder head, incline ignition plug toward the exhaust port, obstruct liquid introduced through the intake valve by a boundary projection formed between the intake and exhaust side conical wall surfaces, etc.

摘要： An exhaust system for internal combustion engines includes at least two exhaust passages, each passage communicated with at least one branch exhaust passage of an exhaust manifold communicating exhaust ports of a multiple-cylinder engine, and a confluent exhaust passage disposed downstream of said at least two exhaust passages, said confluent exhaust passage including a confluent point for converging downstream ends of said at least two exhaust passages. The exhaust system also includes a communication passage substantially parallel with the at least two exhaust passages and a valve disposed in the communication passage, for allowing a portion of exhaust gas flow to bypass said confluent point only when the engine is within a predetermined high engine revolution range.

摘要： A measuring light of specific wavelength, which is selectively absorbed by fuel, is transmitted through a measuring passage in a combustion chamber of an engine, to be received by a light receiving element, and intensity of the measuring light of specific wavelength received by the light receiving element is detected. Intensity of the measuring light having transmitted through the measuring passage is calculated, correcting the intensity of the light of specific wavelength detected when transmitting the measuring light through the measuring passage, with the intensity of the light of specific wavelength detected when intercepting the measuring light from transmitting through the measuring passage, while switching between the transmission of the measuring light through the measuring passage and the interception of the measuring light, and transmittance of the measuring light is calculated, based on the intensity of the measuring light before transmitting through the measuring passage and the intensity of the measuring light having transmitted through the measuring passage, so that fuel density in air-fuel mixture in the measuring passage is calculated based on the transmittance. Hereby, the fuel density can be accurately measured by removing an influence by the thermal radiation in the interior of the combustion chamber.

摘要： A data processing system which executes pipeline processing that decodes a subsequent instruction in an execute phase of a current instruction in response to a clock signal. The data processing system includes a CPU and a mode management block. The CPU supplies an address bus with at least one predetermined address in an execute phase of a clock supply stop instruction. The mode management block produces a clock stop signal if the predetermined address agrees with a self-address assigned to the management block in advance, thereby halting the supply of the clock signal. This makes it possible to solve a problem of a conventional data processing system in that it executes the instruction next to the clock supply stop instruction in spite of execution of the clock supply stop instruction because the clock stop signal is actually output when the clock supply stop instruction shifts from the execute phase to the write back phase, in which case the next instruction proceeds in the execute phase.

摘要翻译： 一种数据处理系统，其执行流水线处理，该流程处理响应于时钟信号对当前指令的执行阶段中的后续指令进行解码。 数据处理系统包括CPU和模式管理块。 CPU在时钟供给停止指令的执行阶段中提供具有至少一个预定地址的地址总线。 如果预定地址与预先分配给管理块的自身地址一致，则模式管理块产生时钟停止信号，从而停止提供时钟信号。 这使得可以解决传统的数据处理系统的问题，因为即使执行时钟供给停止指令，它执行时钟供给停止指令旁边的指令，因为当时钟供给停止时实际输出时钟停止信号 指令从执行阶段转移到写回阶段，在这种情况下，下一个指令在执行阶段中进行。

摘要： A direct-injection type spark-ignition internal combustion engine comprises a fuel-injection valve whose spray hole is inclined toward a piston crown, while an uppermost line of fuel spray injected through the spray hole is set at a lower level than electrodes of the spark plug and a lowermost line of the fuel spray is in spaced relationship with a cylinder inner wall close to the spray hole. The piston crown is formed with a recessed portion and a raised flat-surface portion to define a ridge line as an intersecting line between them. The ridge line is offset from a center axis of the cylinder by a predetermined distance toward the exhaust-valve port side. Preferably, a spray angle between the uppermost and lowermost lines is set within a predetermined angle range of 70.degree..+-.20.degree..
