Abstract
Official abstract text for this publication.
Provided is a mounting structure of a water injection device of an internal combustion engine. The mounting structure is for a water injector (11) of the internal combustion engine. The water injector (11) is mounted to the intake port (6) of the internal combustion engine (1) installed in a vehicle and injects water into the intake port (6) during operation of the internal combustion engine (1). The water injector (11) has a body part (12) mounted to the intake port (6) and an injection port (13a) disposed at the front end of the body part (12) in a state of facing the interior of the intake port (6) and injecting water (W). The intake port (6) has an inclined wall (21) for preventing water from flowing to the downstream side of the intake port (6) when water leaks from the injection port (13a).
First claim
Opening claim text (preview).
What is claimed is: 1. A mounting structure of a water injection device of an internal combustion engine, the water injection device being mounted to an intake port of the internal combustion engine installed in a vehicle and injecting water into the intake port during operation of the internal combustion engine, wherein the water injection device has a body part mounted to the intake port and an injection port disposed at a front end of the body part in a state of facing an interior of the intake port and injecting water, and the intake port has a leaked water blocking part for preventing water from flowing to a downstream side of the intake port when water leaks from the injection port. 2. The mounting structure of the water injection device of the internal combustion engine according to claim 1 , wherein the body part is mounted to an upper part of the intake port, and the leaked water blocking part is disposed below the injection port on an inner wall of the intake port and has an inclined wall formed to be inclined forwardly downward from a vicinity of the injection port toward an upstream side of the intake port. 3. The mounting structure of the water injection device of the internal combustion engine according to claim 2 , wherein the body part is mounted to the intake port so that an intersection point between the inner wall of the intake port and a vertical line passing through the injection port is located on the inclined wall. 4. The mounting structure of the water injection device of the internal combustion engine according to claim 2 , wherein the body part is mounted to the intake port so that on the inclined wall, a tangential plane comprising an intersection point with a vertical line passing through the injection port is inclined forwardly downward toward the upstream side of the intake port.
