Title: solenoid valve manifold
Inventor: HAYASHI ATSUO
IPC: F16K27/00
Filed: 2022-02-22
Abstract: To suppress the pressure loss of fluid.SOLUTION: A first check valve 40A is arranged in a first discharge flow path 34. Part of a discharge port 49 overlaps with a valve seat 48 in a direction perpendicular to the moving direction of a valve element 41. Thus, when the valve element 41 separates from the valve seat 48, fluid flowing out of a first discharge port via a valve hole 47 into a valve chest 46 avoids passing through a gap between the valve element 41 and a peripheral wall 45b in a range to the discharge port 49. Accordingly, the fluid flowing out of the first discharge port via the valve hole 47 into the valve chest 46 is discharged via the discharge port 49 into the first discharge flow path 34 without passing through the gap between the valve element 41 and the peripheral wall 45b. As a result, the fluid is smoothly discharged from the first discharge port into the first discharge flow path 34.SELECTED DRAWING: Figure 2

Title: Premixing compression self-ignition internal combustion engine and its control method
Inventor: TAKAHASHI EIJI
IPC: F02B23/00
Filed: 2022-02-24
Abstract: To obtain stable ignition and combustion by simple control, and a favorable exhaust composition.SOLUTION: An internal combustion engine which performs premixing compression self-ignition comprises a compression ratio variable mechanism which can change a mechanical compression ratio using a multi-link piston crank mechanism. The mechanical compression ratio is controlled so that the highest in-cylinder pressure crank angle θ Pmax approaches a target θ Pmax as an index indicating a combustion state. The target θ Pmax is calculated from an engine rotational speed (S1, S2) and load, and when a difference between the target θ Pmax and an actual θ Pmax is equal to or larger than a prescribed value, a compression ratio correction amount is acquired by multiplying a gain to the difference (S3, S5), and the target compression ratio is obtained by adding the compression ratio correction amount to a current actual compression ratio (S6). By the feedback control of the mechanical compression ratio, the θ Pmax is converged to the target θ Pmax.SELECTED DRAWING: Figure 2
