4results about How to "Reduce intake resistance" patented technology

This invention relates to a commercial vehicle intake system and a commercial vehicle, belonging to the field of vehicle power systems. The technical solution is as follows: A commercial vehicle intake system includes an intake duct, an oil filter, and an air filter connected sequentially along the airflow direction. A water-screening assembly is installed within the air inlet of the intake duct, comprising a water-screening plate and a water collection hopper, the bottom of which connects to the outside of the intake duct. A tower-type water-filtering assembly is installed within the air outlet of the intake duct, comprising multiple stacked blades, with a first water collection trough below the blades. A swirl assembly is installed at the air inlet of the oil filter, comprising a swirl fan, with a second water collection trough below the fan. This solution, through a three-stage water removal assembly, gradually separates moisture from the air while simultaneously improving the removal capacity of dust and other impurities, significantly reducing the moisture and dust content of the air entering the oil filter and air filter, thus ensuring the service life of the oil filter and air filter and the combustion performance of the engine.

This invention provides a jet-type gas turbine guide device, including a guide, a heat dissipation assembly, and a flow divider. The guide consists of an outer ring, inside which is an inner ring. The invention features a hollow cavity inside the blade, with heat dissipation holes arranged along the inner side of the blade, communicating with the hollow cavity. Through holes are formed around the surface of the outer ring, and fuel injectors are installed on the surface of these through holes. During operation, the fuel injectors inject fuel into the hollow cavity inside the blade through the through holes. The fuel entering the hollow cavity carries away the heat generated by the blade, thus cooling it and preventing thermal stress at the leading edge that could cause cracks. The fuel flows out through the heat dissipation holes and into the combustion chamber. This guide has a cooling and heat dissipation structure, thereby improving its service life.

To address the limitations of existing pulse detonation combustors using detonation jet ignition, which require long jet tubes and thus restrict the increase of their operating frequency, and the dependence of stable operation of pulse detonation turbine engines on the performance and reliability of the igniter, this invention proposes a pulse detonation combustor based on rotating detonation wave ignition. This invention utilizes the relatively high frequency of rotating detonation combustion and the requirement for only a single ignition. The rotating detonation wave generated by the rotating detonation chamber serves as a continuous high-energy ignition source, igniting the explosive mixture within the detonation jet channel. This creates a high-energy detonation jet at the channel's exit, which then flows into the pulse detonation tube and ignites the explosive mixture within. This invention, while maintaining the excellent initiation performance of the detonation jet ignition method, overcomes the adverse effects of long jet tubes and high-frequency ignition on the efficient and stable operation of pulse detonation turbine engines.
