Problems solved by technology

However, most of the exhaust braking systems currently in use use an additional executive mechanism on the engine exhaust valve to realize exhaust braking, which not only increases the difficulty in the structural design of the engine's valve train, cylinder head and lubrication system, but also increases the difficulty of manufacturing. It is also difficult to process and assemble the components of the dynamic system and the engine body. Therefore, we have proposed a hydraulic exhaust brake system

Abstract

The invention relates to a hydraulic type exhaust braking system, which consists of an electromagnetic valve (1), a fuel gas control valve (2), a hydraulic oil pipe (3) and a fuel gas pipeline (4), wherein the electromagnetic valve (1) is connected with the hydraulic oil pipe (3), the hydraulic oil pipe (3) is connected with the fuel gas control valve (2), and the fuel gas control valve (2) is connected with the fuel gas pipeline (4). The hydraulic type exhaust braking system does not affect the structure design of other parts of the engine cylinder head part, and the complete machine processing and assembling technology is simple.

Description

technical field [0001] The invention belongs to the field of brake systems, and in particular relates to a hydraulic exhaust brake system. Background technique [0002] Today's vehicle power generally adopts a combined structure of an exhaust brake system and a mechanical disc brake system to achieve vehicle braking. No matter which exhaust braking system controls the gas in the engine cylinder, it releases a part of the high-pressure gas in the cylinder during the power stroke. When the piston goes down, the intake and exhaust valves are closed, and the engine is driven by the vehicle transmission Do negative work (equivalent to vacuuming the top of the piston) to start the braking effect of the vehicle. [0003] When a vehicle equipped with an exhaust brake system needs to decelerate and brake while driving, it only needs to activate the exhaust brake system (no need to step on the mechanical brake system to brake the vehicle), which is reliable and reduces mechanical T...
