摘要： The purpose of the present invention is to provide a urea solution injection nozzle in which deposition and growth of urea on the surface of the urea solution injection nozzle are minimized. A urea solution injection nozzle is provided with urea solution flow paths and gas flow paths. A mixture of urea solution and gas are injected from an injection port. A slit that is a side-surface discharge port is configured so that gas is discharged along a curved surface on the outer surface of the urea solution injection nozzle in the same direction as the injection direction of the urea solution. The slit and the flow path are connected by a branching flow path.

摘要： An engine device executes the control of the opening degree of a main throttle valve when engine load is in a low load area. In contrast, when the engine load is in a medium-to-high load area, the engine device sets the main throttle valve to a predetermined opening degree and executes the control of the opening degree of an air supply bypass valve.

摘要： The purpose of the present invention is to provide an exhaust purification device that is capable of adding an appropriate amount of urea solution without the need to directly measure the NOx emissions amount using an NOx measuring means. The exhaust purification device uses urea solution as a reducing agent for reducing nitrogen oxides within exhaust, and is provided with a temperature sensor, a humidity sensor, and a control device. A map is stored in the control device, and in said map the real NOx emissions amount for each rotation speed and each load of an engine occurring at a predetermined air temperature and a predetermined absolute humidity are converted using a correction formula into a reference NOx emissions amount for each rotation speed and each load of the engine while in a standard state. Using the map, the control device calculates a reference NOx emissions amount that corresponds to the rotation speed detected by a rotation speed sensor and to the load detected by a load sensor, uses the correction formula to convert the reference NOx emissions amount into the real NOx emissions amount occurring at an air temperature and an absolute humidity, and calculates a urea solution addition amount.
摘要翻译： 本发明的目的是提供一种能够添加适量尿素溶液而不需要使用NOx测量装置直接测量NOx排放量的排气净化装置。 排气净化装置使用尿素溶液作为还原剂来还原排气中的氮氧化物，并且设置有温度传感器，湿度传感器和控制装置。 映射存储在控制装置中，在该图中，使用修正公式将每个转速的实际NOx排放量和在预定空气温度和预定绝对湿度下发生的发动机的每个负荷转换为参考NOx排放 在标准状态下每个转速和发动机的每个负载的量。 使用该图，控制装置计算与由转速传感器检测的转速相对应的基准NOx排出量和负载传感器检测到的负荷，使用校正公式将基准NOx排放量转换为实际NOx 在空气温度和绝对湿度下发生排放量，并计算尿素溶液添加量。
