TH845A - Fuel injection rate limiter for diesel engines - Google Patents

Abstract

The fuel injection rate limiter for diesel engines is intended to improve engine performance at start-up and when operating under extreme conditions. With a limiter to control the speed regulator axis under Fully loaded But at the same time the control axis Fast, it can be moved to resist the bill spring. The fuel injection increases while the engine speed decreases. Additionally, during the start-up, the speed regulator core is forced. To move farther against the torsion spring, including the spring starts to walk The machine makes the fuel injection rate increase, thus making Improved engine start-up performance also has the purpose of being able to adjust the fuel injection rate. Increased by high fidelity while the engine operated Work under extremely high load conditions and during start-up

1. Fuel injection rate limiter for diesel engines including: 13 speed regulator mechanism for controlling the injection rate. The fuel of the fuel injection pump 12 of the diesel engine 11, the seat limit range 15, is built as part of the control device. 14 stationary speed control mechanism 13 stationary cylinder 19 are installed away from the pump. Fuel injection 12 at the given location. And in the direction The way to increase the fuel injection rate "r" of the shoulder limit range of 15 moving cylinders 20 placed in a stationary cylinder 19 can be moved longitudinally back and forth quite significantly. The direction of movement of the shoulder limiting distance 15, the speed limiting fuel injection rate 16, is placed through hole 30 and hole 21 located on the front wall of the movable cylinder 20 and the stationary cylinder 19, respectively, extending from the inside. Of movable barrel 20 and can slide freely through hole 21 and hole 30 Extending through the front wall of the cylinder Stationary 19 to face the shoulder limit at 15, the first screw 23 facing the rear part of the barrel. Movable 20 with adjustable longitudinal position. The first spring 17 is compressed between the first adjustment screw 23 and the fuel injection rate limiter 16 inside the movable cylinder 20 activates the rate limiting speed. Fuel injection 16 in a direction that reduces the fuel injection rate "1". The first stage 26 is placed between the first adjustment screw 23 and the fuel injection rate limiter 16 is inside the movable cylinder 20 for Set the distance "A" with the notorious rate limiting fuel injection 16 can be directly applied to the first adjustment screw 23 in the direction of the additional compression item "r" second adjustment screw 25 facing the rear of Cylinder that Stationary 19 with adjustable longitudinal position The second spring 18 compressed between the second adjustment screw 25 and the movable cylinder 20 is placed in the stationary cylinder 19, which can encourage the moving cylinder 20 to move forward. The second set of inspection part 27 is placed between the second adjustment screw 25 and the first adjustment screw 23 inside the stationary cylinder 19 to set the "B" distance, where the movable cylinder 20 can It goes directly to the second adjusting screw 25 in a direction that increases the fuel injection rate "I" and the arrangement makes the tension of one of the first springs 17 and the second 18 less than the force. That makes the device The movable control 14 of the speed control mechanism 17 moves in a direction that increases the fuel injection rate. While another spring will be set to Has higher tensile force, acts as a starting spring (1 claim, 1 page, 5 photos)
