Abstract: The present invention belongs to the technical field of diesel engines, and particularly relates to an engine cooling system and a cooling method therefor. In the engine cooling system of the present invention, when an engine needs to be warmed up, a first valve is opened, a lower engine body water storage chamber is in communication with an upper engine body water storage chamber, and some of the cooling water directly flows into the lower engine body water storage chamber from the upper engine body water storage chamber. The flow of the cooling water entering an engine body is reduced, and under the condition that heat dissipated by the engine is unchanged, the temperature rise of the cooling water flowing through the engine body such as a cylinder sleeve upper cooling water chamber and a cylinder sleeve lower water jacket is faster, such that an engine warming effect is improved.

Abstract: A multiport valve, having a housing having at least two connectors, a control element for blocking at least one of the connectors, the control element disposed to be rotatable in a recess of the housing. An external contour of the control element has a compression portion which in at least one first position of the control element compresses a first seal disposed on a first one of the connectors. The external contour of the control element has a decompression portion that has a smaller radius than the compression portion and in at least one further position of the control element lies opposite the first seal such that the control element compresses the first seal to a lesser extent than in the first position.

Abstract: A cooling circuit includes vehicle components and a jet manifold. The vehicle components are configured to receive coolant and include a first vehicle component and a second vehicle component. The jet manifold includes a first input, a second input and a nozzle. The first input is configured to receive coolant from the first vehicle component. The second input is configured to receive coolant from the second vehicle component. The nozzle is configured to increase pressure of the coolant received at the first input to generate a jet stream and a low-pressure zone in a cavity of a body of the jet manifold, the low-pressure zone created by the jet stream drawing coolant from the second input.

Abstract: An apparatus for handling fluid within an at least partially electrically driven vehicle, with a valve device including a valve housing. The valve housing includes at least three two radially arranged port openings and at least one axially arranged port opening for the inflow and/or outflow of fluid, and a valve body which is arranged inside the valve housing and is configured to be rotatable about an axial axis of rotation R. The valve body includes a first connecting channel of arcuate shape for connecting two radially arranged port openings and a second connecting channel of arcuate shape for connecting a radially arranged port opening with an axially arranged port opening. The at least two radially arranged port openings define a base plane B, which is configured orthogonally to the axial axis of rotation R, and the first arcuate connecting channel defines a first connecting channel plane V.

Abstract: An engine system of the present disclosure includes an engine configured to drive a plurality of pistons by burning a mixture of air and gas, an air supply pipe through which the air supplied to the engine flows, a supercharger configured to compress the air flowing through the air supply pipe, a gas supply pipe through which the gas supplied to the engine flows, and a mixer configured to mix the air that has passed through the supercharger and the gas. The mixer has a venturi tube shape in which a cross-sectional area of a flow path decreases and expands in a flow direction of the air that has passed through the supercharger, and the gas supply pipe is connected to a portion of the mixer where the cross-sectional area of the flow path in the mixer is decreased.
