Embodiment Construction

[0022] refer to Figure 1 to Figure 5 The first embodiment of the present invention is described, first in conjunction with figure 1 and figure 2 , the diesel engine in the embodiment includes an intake manifold and an air filter, and a swirl control device is arranged at the front end of the intake manifold, and the inlet end of the swirl control device is connected with the air filter through an intercooler and a supercharger Or directly connected to the air filter, the outlet of the swirl control device is connected to the inlet of the intake manifold.

[0023] The vortex control device connected to the engine intake manifold has a vortex channel 01 and a vortex control unit. The vortex channel 01 is made of AlSi10Mg material and is divided into a main part 011 and two branch parts 012 and 013, namely the high-speed vortex forming channel, The low-speed vortex forms a channel, the inlet end of the main body part 011 is connected to the intercooler (not shown) or directly...

Abstract

A diesel engine includes an inlet manifold and an air filter. At the front end of the inlet manifold is disposed a vortex controller, the inlet end of which connected with the air filter via a mid-cooler and a supercharger or connected with the air filter directly, the outlet end of which connected with the inlet of the inlet manifold.

Description

technical field [0001] The invention relates to a diesel engine, more specifically to a diesel engine capable of realizing swirl control on intake air. Background technique [0002] For diesel engines, unlike gasoline engines, there are certain restrictions on the intake volume of output adjustment. The current diesel engine basically does not have a vortex control device that controls the intake air to a certain extent. The gas coming from the air filter either passes through the supercharger and then passes through the intercooler and finally reaches the intake manifold, or there is no supercharger and intercooler. The cooler goes directly into the intake manifold, the gas from the EGR (exhaust gas recirculation) valve. Usually EGR gas enters the intake system by using vacuum to suck the exhaust gas into the intake system, but the technology used by each company is different. For example, the EGR cycle of a certain engine is formed by using the following method. The exha...
