摘要： In order to promote a good flame dispersion within the combustion chamber of a swirl chamber type Diesel engine, a shaped recess formed in the piston crown is arranged to have a trench portion into which the flame from the swirl chamber is injected and mirror image flame dispersion portions on either side of the trench which terminates at the periphery of the piston crown. This arrangement inhibits the formation of secondary flame flows which tend impede desirable patterns within the flame disportion portions and simultaneously enlarges the dispersion area. In addition, careful selection of the dimensions of the transfer port which interconnects the swirl chamber and the main combustion chamber, and the various sections of the shaped recess, promotes further reductions in HC and smoke emissions.

摘要： A vibration sensor for an automotive vehicle including a piezoelectric vibrator of cantilever type for detecting mechanical vibrations, such as knocking, from an engine body. The vibration sensor prevents the vibrator from being deformed by thermal stress even if temperature near the sensor rises sharply, so that a stable resonant frequency will be maintained when detecting the vibration of an engine body.

摘要： An auxiliary flow control valve is disposed in an exhaust gas recirculation passageway at a location upstream of a main flow control valve controlling the flow rate of exhaust gases recirculated into an intake system. Two conduits communicating with an intake manifold communicate with a vacuum chamber of a servo motor controlling the main flow control valve. One of the conduits has formed therein a restriction to limit the flow rate of fluid therethrough. A check valve is disposed in the other conduit to close the same when the vacuum in the intake manifold is increased and constant and to open the other conduit when the vacuum in the intake manifold is reduced.
