摘要： Wall surfaces which define essentially circular recesses are constructed to deflect the flow of burning gases from a swirl chamber in a manner to either tighten the swirl formed therein or to improve the initial splitting of the frame in a manner which increases the amount of gases which are induced to undergo swirling in the recesses.

摘要： In an apparatus for treating exhaust particulates in a diesel engine, a basal fuel injection timing is determined based on an engine operating condition. When the engine operating condition falls in a predetermined operating range, the basal fuel injection timing is corrected, and operation of a fuel injection pump is modified.

摘要： Parameters which are related to the rate at which particulate matter accumulates and is reburnt, are monitored and the time at which a regeneration is required and/or the length of time a regeneration should be induced, are derived based on the same. The temperature at the inlet and outlet of a trap in which particulate matter is accumulated are monitored and measures such as throttling the induction and exhaust are implement in addition to energizing a heater disposed immediately upstream of the trap as required in order to elevate the trap temperature and to induce and maintain the reburning during a trap regeneration. The pressure differential across the trap can be used to determine the amount of incombustible matter (ash) which has accumulated in the trap and to modify the regeneration timing. When the temperature of the exhaust gases cannot be raised sufficiently, a by-pass is opened to attenuate cooling of the trap by the low temperature gases.

摘要： The major portion of a flame which ejects from a swirl chamber by way of a transfer passage, is subject to first and second deflections. The first occurs close to TDC, the second after the piston has decended a predetermined amount. A minor portion of the flame which tends to flow in a direction essentially the reverse of the main one, encounters a curved deflection wall portion and is thereafter subject to guidance by guide members which induce the flame to blend with the air located proximate the location of the transfer passage opens into the combustion chamber. A variation of the basic arrangement includes the provision of a squish generating projection which promotes suitable mixing turbulence near the curved deflection wall portion.

摘要： An exhaust gas purifying device which is provided with catalytic converter and a fuel injector which are disposed upstream of a particulate matter trap. The fuel injection injects fuel to the catalytic converter to rise exhaust gas temperature by its oxidation reaction heat when the exhaust gas temperature is slightly lower than a predetermined regeneration temperature. Further, a closable bypass passage is communicated with the passage between the catalytic converter and the trap and functions to allow to bypass exhaust gases in accordance with the trap condition and the exhaust gas temperature.

摘要： A piston is free to slide in an engine cylinder, this piston comprising a piston head of circular cross-section, a skirt formed such that it is continuous with the lower part of said piston head, a piston pin passing through the skirt, and a connecting rod connected via this piston pin. This skirt comprises an upper part and a lower part which respectively have an elliptical horizontal cross-section with a short axis parallel to the piston pin, the horizontal cross-section of the upper part of the skirt having a higher eccentricity than that of the lower part of the skirt. The skirt further comprises a taper surface which smoothly connects its upper and lower parts. The contact surface between the skirt and the cylinder therefore has an inverted T shape so that the contact surface of the lower part of the skirt can be increased. It is therefore possible to set the distance from the center of the piston pin to the lower edge of the skirt such that it is no greater than 1.8 times the distance from the center of the piston pin to the upper edge of the skirt, so making the piston more compact while maintaining operational stability.
