摘要： In order to avoid the formation of smoke and HC when the compression ratio of a swirl chamber type Diesel engine is lowered either by design or by operation in rarified atmospheres, the fuel injector is located on one side of the center axis of the swirl chamber so as to maximize the distance for which the injected fuel can travel before contacting a wall of the chamber and the auxiliary transfer port through which a fraction of the injected fuel is fed to the main combution chamber is arranged so that the axis thereof intersects the axis of the fuel injector and therefore the trajectory along which fuel is injected, at a point defined within the swirl chamber per se and on the opposite side of the center axis with respect to the fuel injector.

摘要： A spark ignition reciprocatory internal combustion engine with dual induction system and with EGR system is provided in which under engine operating conditions when only a primary throttle valve opens, a fluid charge from a primary induction system will swirl around the cylinder axis, while, under engine operating condition when both the primary and secondary throttle valves open, a fluid charge from a secondary induction system will impede and reduce swirling motion of fluid charge from the primary induction system. With the EGR system, the recirculation of exhaust gas is effected through the primary induction system under the engine operating condition with low and intermediate loads. At high loads, the recirculation of exhaust gas is effected not only through the primary induction system but also through the secondary induction system. For this end the EGR system includes a load responsive valve which will permit admission of exhaust gas into the secondary induction system at a position downstream of the secondary throttle valve in response to loads of the engine.

摘要： A spark ignition reciprocatory internal combustion engine with dual induction system is provided which has within a cylinder head a primary induction passage or a primary intake port passage to direct fluid charge into a cylinder to swirl therein and a secondary induction passage or a secondary intake port passage to direct fluid charge into the cylinder in such a direction as to impeded and reduce the swirling motion of the first fluid charge to provide a low "swirl ratio" within the cylinder, thereby to maintain the volumetric efficiency of the engine at a sufficiently high level. A primary throttle valve is provided to control the quantity of fluid charge entering into the primary induction passage and a secondary throttle valve is provided to control the quantity of fluid charge entering into the secondary induction passage. The secondary throttle valve is coordinated with the primary throttle valve so that the secondary throttle valve will remain closed until the primary throttle valve opens wider than a predetermined opening degree. Under engine operating conditions when only the primary throttle valve opens, fluid charge from the primary induction passage will swirl at a high "swirl ratio" in the range of 1.5 to 6, while, under engine operating conditions when both the primary and secondary throttle valves open, fluid charge from the secondary induction passage will impede swirling motion of fluid charge from the primary induction passage to provide a low "swirl ratio" in the range of 0.5 to 1 within the cylinder, and to maintain a high volumetric efficiency of the engine.

摘要： Disclosed is a split engine control system wherein the intake manifold is segmented by a shut-off valve into a first chamber portion leading to a first group of cylinders and a second chamber portion leading to a second group of cylinders. During periods of relatively low load, the cylinders of the second group are deactivated and the shut-off valve is closed to isolate the second chamber from the first chamber to cut off air supply to the deactivated cylinders. Exhaust gases are recirculated through the deactivated cylinders so that their pumping loss is minimized. A pressure detector is provided to detect a pressure difference which might develop between the first and second chambers during the partial cylinder operation to control the flow rate of the recirculated gases until the pressure difference reduces substantially to zero.
