Abstract: A wheel-side reducer system includes a housing, a speed reduction assembly, and a steering knuckle. The housing includes a front housing and a rear housing. The front housing and the rear housing are arranged opposite to each other and define an accommodating space together. The speed reduction assembly is arranged in the accommodating space. The steering knuckle is integrally molded on the front housing. The integrally molding of the steering knuckle on the front housing not only simplifies the production process of the housing, but also makes a connection between the steering knuckle and the front housing more reliable. Meanwhile, the integration level of the wheel-side reducer system can also be improved, to reduce the size of the wheel-side reducer system. A vehicle with the wheel-side reducer system is further disclosed.

Abstract: An engine assembly includes an air inlet pipe having an air inlet, an air supply port, and an air return port. The air inlet communicates with air. The air supply port communicates with an air inlet manifold of an engine. In a length direction of the air inlet pipe, the air return port is located between the air inlet and the air supply port. An air inlet control valve is disposed on the air inlet pipe, and located between the air inlet and the air return port. An exhaust gas return pipe communicates with the air return port. An exhaust pipe communicates with the exhaust gas return pipe and an exhaust manifold of the engine. In the length direction of the air inlet pipe, a distance S between the air return port and the air inlet control valve and an inner diameter D of the air inlet pipe meet S/D≤2.

Abstract: An engine includes a cylinder block, a cylinder head, and a piston. The cylinder head is connected to the cylinder block. The piston is movably connected to the cylinder block. The cylinder block, the cylinder head, and the piston form a combustion chamber. The cylinder head includes an intake valve hole and an exhaust valve hole. An intake valve is disposed at the intake valve hole and an exhaust valve is disposed at the exhaust valve hole. A barrier protrusion is protruded at the edge of the intake valve hole away from the exhaust valve hole. The included angle between a first connecting line connecting a first end of the barrier protrusion and a center of the intake valve hole and a second connecting line connecting a second end of the barrier protrusion and the center of the intake valve hole is greater than 120 degrees and less than or equal to 180 degrees.

Abstract: A hybrid powertrain includes a drive member, a first clutch, a second clutch, a first electrical machine, an engine, and a reverse piece. The first clutch is connected to an engine output shaft and the drive member, to selectively connect the drive member and the engine output shaft. The second clutch is connected between the drive member and the reverse piece. The reverse piece is connected between the second clutch and a first drive wheel, to selectively connect the drive member and the first drive wheel. The first electrical machine is connected to the drive member, and the first electrical machine and the engine are selectively connected through the first clutch. When the engine outputs power to the first drive wheel, a rotation direction of the engine output shaft and a rotation direction of the first drive wheel are the same by a reversing operation of the reverse piece.
