摘要： An apparatus for detecting knock for an internal combustion engine having a plurality of cylinders in which a vibration sensor is attached to each cylinder and a peak value of vibration detected by the sensor is sampled over a predetermined range near the top dead center. The sampled value is converted from analog to digital and stored for a predetermined number of sampling times to obtain the average value for each cylinder. Then the frequency of occurrences in which the ratio between the sampled peak value and the average value exceeds a reference value is obtained, and the knock is determined when the frequency of occurrences in any one cylinder exceeds a predetermined value or when the average frequency of occurrences of the all cylinders exceeds another predetermined value.

摘要： Disclosed is an EGR system of an internal combustion engine, in which a part of the exhaust gas is drawn out from an exhaust pipe and returned to an intake pipe through a control valve, and a reference pressure in the intake pipe corresponding to the amount of recirculated exhaust gas, predetermined by experiment (beforehand) in various combinations of engine intake air flow and speed, is memorized in a memorizing device. The reference pressure responding to the amount of sucked air being introduced into the engine and the engine rotating speed in the case of actual operation of the engine is read out from the memorizing device and, then, compared with the real pressure in the intake pipe in the case of actual operation of the engine. The control valve has a diaphragm chamber, into which positive or negative pressure is introduced, which pressure is controlled by a solenoid valve actuated by a signal from a control device so as to make the real intake pipe pressure coincide with the reference intake pipe pressure.

摘要： Disclosed herein is a computer control system of an exhaust gas recirculation device for an internal combustion engine, wherein values of the parameters of desired EGR ratios when various conditions in the engine intake system exist are preliminarily stored in the memory of the computer, and wherein a value of a parameter is read out from the memory by detecting a value of the engine condition during its operation. In the system, values of temperature correction factors with respect to at least one temperature characteristic of the engine are also preliminarily stored in the memory. A temperature correction value is read out from the memory in accordance with a detected temperature value of at least one portion of the engine. The computer calculates the amount of EGR needed from the read out values of desired EGR and temperature correction and produces an electrical signal for controlling operation of the EGR value.

摘要： An exhaust gas recirculator wherein a double diaphragm type flow control valve is disposed in a recirculating passage which couples an exhaust system and an intake or suction system of an internal combustion engine. The flow control valve includes first and second diaphragms, and is formed with a first pressure control chamber partitioned by a first diaphragm and a second pressure control chamber partitioned by the first diaphragm and a second diaphragm. Vacuum is introduced into the first and second pressure control chambers from vacuum ports provided in the vicinity of a throttle valve of a carburetor. Thus, the stroke of a valve shaft of the flow control valve and accordingly the opposing area between a valve body and valve seat of the flow control valve are controlled in two stages, so that the single flow control valve can control the amount of recirculative exhaust gas in two stages.

摘要： In an carburetor where a shaft is positioned within a bearing section and there is no lubricant, such as oil or water, used between the shaft and bearing section, a flow of pressurized air is directed through a passageway into the bearing section and then into a slot which extends in the circumferential direction so that air can be directed axially between the shaft and the bearing section. The flow of air prevents the entry of any alien substances, such as dust or moisture, into the space between the shaft and the bearing section.
