An electric motor and inverter assembly () used in an electric vehicle or a hybrid electric vehicle to drive the vehicle's wheels to rotate is disclosed. The electric motor and inverter assembly comprises: an electric motor (), which includes a housing including a main shell (), an end cover () and a connecting cover (), wherein a cooling passage is formed in a wall of the housing such that coolant is able to flow in the cooling passage, and an end cover () and a connecting cover () are respectively connected to opposite ends of the main shell; and an inverter, which includes a housing () in which a power element and/or an electrical device is received, wherein the housing of the inverter contacts the connecting cover such that an interface is defined between the connecting cover and the housing of the inverter, and the coolant flowing through the cooling passage is able to contact the interface.

Electric motor and inverter assembly

An electric drive system () used in an electric vehicle or a hybrid electric vehicle to drive the vehicle's wheels to rotate. The electric drive system () includes an electric motor (). The electric motor () includes a housing in which a stator and a rotor are received. A transmission device () is operatively coupled to the electric motor (); and an output shaft () is operatively coupled to the transmission device (). The output shaft () extends from the transmission device () and is substantially parallel to the rotor's axis of the electric motor (). The electric drive system () also includes an inverter () secured over the housing of the electric motor () such that the inverter is located between the output shaft () and the housing of the electric motor ().

Electric drive system

A high-pressure fuel pump for a fuel injection system of an internal combustion engine includes a pump housing and at least one fastening flange that is fixed to the pump housing by a welding. The welding has one weld region and at least one weld bead arranged laterally from the weld region. The weld bead is arranged in a receiving space formed between the pump housing and the fastening flange.

High-pressure fuel pump

A piston fuel pump for an internal combustion engine includes a pump housing, a piston, and a non-return discharge valve. The non-return discharge valve has a valve element and a guide element configured to guide the movement of the valve element. The guide element is at least indirectly pressed in a radial manner into an opening in the pump housing.

Piston fuel pump and check valve therefore

A piston fuel pump for an internal combustion engine includes: a pump cylinder; and a pump piston which is movably accommodated in the pump cylinder. The pump piston is guided radially with the aid of at least a first and at least a second guide section which are spaced axially apart from each other, the first guide section being situated in a pump cylinder of the piston fuel pump, and the second guide section being situated radially outwardly in the area of the end section facing the drive. The piston fuel pump has a supporting and sealing unit for the pump piston on the first guide section, which includes a guidance area for the radial guidance of the pump piston in the pump cylinder and a sealing area having a sealing lip.

Piston fuel pump for an internal combustion engine

A piston fuel pump for an internal combustion engine includes a pump cylinder and a pump piston that is configured to be axially displaced in the pump cylinder. A working chamber is defined by the pump piston. A seal is provided on the pump cylinder, which seals the working chamber counter to a low pressure region. The seal is applied directly to the pump piston by an injection molding method.

A piston-type fuel pump for an internal combustion engine includes a pump housing, a piston, an annular counterplate, and a non-return outlet valve. The pump housing includes a stepped opening and a piston opening. The piston is guided in the piston opening. The counterplate is pressed into the stepped opening and includes a valve seat. The non-return valve includes a valve element and a guide element. The guide element guides the valve element, is arranged radially outside the valve element and in the stepped opening, and includes a guide section, a retention section, and a support section. The guide section guides the valve element, the retention section is connected to the guide section via a radially extending connecting section, and the support section supports a valve spring. The sections are arranged axially at different points such that the guide section is between the counterplate and the support section.

Piston fuel pump

A piston fuel pump for an internal combustion engine includes a pump cylinder, a pump piston, and a seal. The pump piston is configured to be moved axially in the pump cylinder, wherein a working chamber is delimited by the pump piston. The seal is disposed on the pump piston and seals off the working chamber from a low-pressure region. The seal seals off an end section of the pump piston adjacent to the working chamber from the working chamber.

A high pressure fuel pump encompasses at least one delivery chamber and one high pressure outlet. in addition, a pressure limiting valve with a valve that is actuated by a pressure differential is provided that can open from the high pressure outlet to the delivery chamber. On a high pressure side of a valve seat of the pressure limiting valve, it is advantageous that a throttle device is provided, whose free cross section is at most approximately equal to a desired maximum opening cross section of the pressure limiting valve.

High pressure fuel pump

A high-pressure fuel pump with a pressure relief valve which has improved hydraulic properties and a reduced number of high-pressure sealing points.

High-pressure fuel pump with a pressure relief valve

An injection system for internal combustion engines is proposed, in which once the engine has been turned off, a pressure equalization is established between the intake side and the pressure side of the high-pressure fuel pump. This prevents uncombusted fuel from reaching the combustion chambers of the engine. The pressure prevailing on the pressure side and the intake side when the engine is off furthermore assures that vapor bubbles cannot form, and this makes starting the engine easier.

Injection system for internal combustion engines with improved starting properties

The invention relates to a refinement of an air guiding system for an internal combustion engine, having an intake conduit which adjoins an air inlet opening downstream and is part of a gas guiding chamber that carries air from the air inlet opening to an outlet opening. In the air guiding system, an air filter is embodied as an interchangeable cartridge in such a way that the air filter is insertable into and removed from the intake conduit.
