摘要： A controller for an internal combustion engine is configured to execute a first injection process that causes a water injection valve to inject water when an intake valve is open and a second injection process that causes the water injection valve to inject water when the intake valve is closed. The controller is further configured to set a pressure of the water supplied to the water injection valve to be higher in the second injection process than in the first injection process.

摘要： This apparatus includes a control device executing a urea adding valve operation control. The control device calculates a target instantaneous supply amount (QC), which is a urea water supply amount for cooling a urea adding valve, based on an engine operation state. The control device considers a target cooling supply amount (TQc), which is a target urea water supply amount for the cooling of the urea adding valve, as an amount obtained by a part of a difference between a previous target cooling supply amount (TQc[i]) and the target instantaneous supply amount (QC) being added to the previous target cooling supply amount (TQc[i]). When a cooling water temperature (THW) is equal to or higher than a predetermined temperature and the previous target cooling supply amount (TQc[i]) is "0", the control device uses the target instantaneous supply amount (QC) as the previous target cooling supply amount (TQc[i]) as it is.

摘要： A relationship between an inner diameter A of a sac volume (30) and a distance (B) from a central axis (c) of the sac volume (30) is set to satisfy a condition of 1≤A/2B≤20. In this way, fuel, which flows from the sac volume (30) into each injection hole (31), will be injected from the injection hole (31) without being spaced from a wall surface of a valve body (21), which form the injection hole (31). Thus, it is possible to limit adhesion of a foreign substance to a wall surface of each injection hole (31). Furthermore, even if the foreign substance is adhered to the wall surface of the injection hole (31), the foreign substance can be removed by the fuel, which flows through the injection hole (31).

摘要： Fuel pipes (190 and 192) guide fuel from a fuel tank (165) provided in a rear area (600R) of the vehicle to a low-pressure fuel supply system (11) and a high-pressure fuel supply system (12), respectively, for injecting the fuel to an engine (10) provided in a front area (600F) of the vehicle. A branch point (Na) between the fuel pipes (190 and 192) is arranged in the vicinity of the fuel tank (165) to secure a long pipe length between the low-pressure fuel supply system (11) and the high-pressure fuel supply system (12). This can suppress variation in fuel pressure at the low-pressure fuel supply system (11) attributable to the fuel that is discharged from the high-pressure fuel pump (200) within the high-pressure fuel supply system (12) back to the fuel pipe (192).

摘要： A controller (80) alternately repeats a desorption process of desorbing sulfur compound deposited on an NSR catalyst (20) by supplying fuel from a direct injection valve (11) to exhaust gas, and a pausing process of pausing fuel supply from the injection valve (11) to the exhaust gas. The controller executes a cooling fuel addition for adding engine fuel from the addition valve of the exhaust passage to cool the addition valve during execution of the pausing process, and prohibit the cooling fuel addition during execution of the desorption process. The controller calculates a target temperature (Td) of the addition valve (35) at the time of start of the desorption process such that the temperature of the addition valve (35) during execution of the desorption process does not exceed an allowable upper limit temperature (Tc) and calculates the addition amount (CA) at the time of cooling fuel addition.

摘要： A aqueous urea solution supply device (200) for an engine (1) is provided with a tank (210) that stores aqueous urea solution, a valve (230) configured to add the aqueous urea solution to exhaust gas, and a passage (240) configured to supply the aqueous urea solution from the tank (210) to the valve (230). When a pressure of the aqueous urea solution supplied to the valve (230) is equal to or lower than a predetermined pressure and the amount of the aqueous urea solution in the tank (210) is equal to or smaller than a predetermined threshold, an electronic control unit (80) determines that the aqueous urea solution in an amount required for cooling of the valve (230) cannot be supplied from the tank (210) to the valve (230) and executes a return control for returning the aqueous urea solution from the valve (230) to the tank (210).

摘要： A controller for an internal combustion engine is configured to execute: a pressure calculation process that calculates pressure of gas in a crank chamber based on a running state of the internal combustion engine; a first injection process that causes a water injection valve to inject a first injection amount of water when an intake valve is open; and a second injection process that causes the water injection valve to inject a second injection amount of water when the intake valve is closed. The controller is further configured to set a ratio of the first injection amount to a sum of the first injection amount and the second injection amount to a smaller value when the pressure is greater than or equal to a specified value than when the pressure is less than the specified value.
