Description

Technical Field

[0001] This invention belongs to the field of vehicle engine structure technology, and in particular relates to an engine assembly and a vehicle. Background Technology

[0002] As the core power component of a vehicle, the engine assembly converts the chemical energy of fuel into mechanical energy. In gasoline-powered vehicles, the engine directly drives the wheels, providing propulsion for the vehicle and simultaneously powering auxiliary components such as the air conditioning compressor, generator, and water pump. In hybrid vehicles, the engine drives a generator to generate electricity or is connected in parallel with an electric motor to drive the wheels. With increasingly stringent vehicle emission regulations, the requirements for the engine assembly's thermal efficiency, NVH performance, integration, and common layout within the engine compartment are continuously increasing.

[0003] The current engine layout structure in the automotive industry has the following main drawbacks: 1. The cylinder head exhaust outlet adopts a non-integrated exhaust manifold design, with an independent layout, resulting in low integration and large space occupation; 2. The oil cooler is separately mounted on the cylinder block, requiring external cooling circulation piping, which is complicated, takes up space, and increases the overall cost of the machine; 3. The front-end wheel system is not compact and usually includes idler wheels, brackets, and other components, resulting in complex assembly processes and high manufacturing and design costs; 4. One engine can only meet the engine compartment layout of one type of vehicle drive, and the modularity of the engine compartment design is low; therefore, there is an urgent need for a new type of engine overall layout structure and vehicle to solve the above-mentioned technical defects.

[0004] In summary, existing technologies urgently need an engine assembly that can meet the vehicle's power performance requirements while reducing the space occupied by the exhaust manifold at the cylinder head outlet, reducing the space occupied by the cooling circulation pipes, reducing the number of engine assembly components, and accommodating the engine bay layout of both longitudinal rear-wheel drive and transverse front-wheel drive vehicles. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide an engine assembly and vehicle to solve the problems of the prior art, such as the large space occupied by the exhaust manifold and cooling circulation pipes at the cylinder head of the engine assembly, the large number of parts in the engine assembly, and the inability of the engine assembly to be adapted to the engine compartments of both longitudinal rear-wheel drive and transverse front-wheel drive vehicles.

[0031] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0032] Please see Figures 1 to 5 This invention provides an engine assembly, including a cylinder block 2-4, a cylinder head 2-5, a cylinder head cover 2-6, a cover 2-7, an ignition coil 1-1, a drive pulley 1-10, a generator 1-6, a generator 1-6 pulley, a water pump 1-12, a water pump 1-12 pulley, a water pump belt 1-14, a compressor 1-7, a compressor belt 1-11, a tensioner 1-13, an electromagnet 1-15, an oil pan 1-9, an oil dipstick 1-3, an oil cooler 2-3, an oil filter 1-8, and an intake manifold. The engine assembly includes a manifold 1-5, a throttle valve 1-4, an exhaust manifold, an exhaust gas recirculation cooler 3-2, an exhaust gas recirculation line valve 3-4, and a fuel rail 1-2. The engine assembly has an engine coolant inlet 2-2 and an engine coolant outlet 2-1. The drive pulley 1-10, generator pulley 1-6, water pump pulley 1-12, and tensioner pulley 1-13 form the engine pulley system. These are all essential technical features of existing engine assemblies and will not be elaborated upon here. The difference between this invention and existing engine assemblies lies in: The engine assembly has intake and exhaust sides on both sides, with the engine wheel system at the front and the transmission at the rear. The exhaust port 3-1 on the exhaust side is located on the cylinder head 2-5. A three-way catalytic converter is directly installed at exhaust port 3-1. The exhaust gas recirculation cooler 3-2 is installed below exhaust port 3-1. The exhaust gas recirculation valve 3-4 is installed at the rear of the cylinder head 2-5. The exhaust manifold is connected to exhaust port 3-1 and is integrated into one unit. The generator 1-6... The water pump 1-12 and the compressor 1-7 are directly mounted on the cylinder block 2-4. The oil cooler 2-3 is directly mounted on the water pump 1-12. The oil filter 1-8 is directly mounted on the oil pan 1-9. The cylinder head cover 2-6 is provided with a wiring harness fixing hole 4-1. The intake manifold 1-5 is connected to the intake port on the intake side. The intake manifold 1-5 is provided with a wiring harness fixing hole 4-2. The wiring harness fixing hole 4-1 and the wiring harness fixing hole 4-2 are used together.

[0033] The engine assembly of this invention has an intake side and an exhaust side on both sides, an engine wheel system at the front end, and a transmission assembly at the rear end. The exhaust port 3-1 on the exhaust side is opened on the cylinder head 2-5, and the exhaust manifold is connected to the exhaust port 3-1. The exhaust manifold is integrated into one unit, and the three-way catalytic converter is directly installed at the exhaust port 3-1. This structural design reduces the space occupied by the existing exhaust manifold and also reduces the use of separate exhaust manifold components, making the engine compartment space of the car more spacious and reducing the overall part cost. The cylinder head cover 2-6 is provided with a wiring harness fixing hole 4-1, the intake port on the intake side is connected to the intake manifold 1-5, and the intake manifold 1-5 is provided with a wiring harness fixing hole 4-2. The structural design of the wiring harness fixing hole 4-1 and the wiring harness fixing hole 4-2 working together avoids the mess of wiring harnesses connected to the engine assembly and also reduces the number of bracket-type components for fixing the wiring harness.

[0034] The engine assembly of the present invention is directly mounted on the cylinder block 2-4 via the generator 1-6, water pump 1-12, and compressor 1-7, eliminating the need for adapter brackets and making the engine assembly more compact. The oil cooler 2-3 is directly mounted on the water pump 1-12, reducing the need for separate water pipes, oil pipes, and other components, making the engine assembly more compact in its external structure. The shorter internal flow path allows for faster cooling of the oil temperature. The design of the oil filter 1-8 being directly mounted on the oil pan 1-9 further eliminates the need for an adapter bracket.

[0035] The engine assembly of the present invention features a structure in which an exhaust gas recirculation cooler 3-2 is installed below the exhaust port 3-1, and an exhaust gas recirculation pipeline valve 3-4 is installed at the rear end of the cylinder head 2-5. This design ensures that the engine compartment space can be accommodated when the engine assembly is matched with a front-wheel drive or rear-wheel drive transmission.

[0036] In other words, the engine assembly of this invention solves the problems of existing engine assemblies, such as the large space occupied by the intake manifolds 1-5 and cooling circulation pipes at cylinder head 2-5, the large number of engine components, and the inability to simultaneously adapt to the engine bays of both longitudinally mounted rear-wheel drive and transversely mounted front-wheel drive vehicles. Compared with existing technologies, while meeting the engine's power performance requirements, it features an integrated structural design, compact layout, reduced production and overall machine costs, fewer parts and lower failure rate, high degree of commonality and modular design in the engine bay, reduced vehicle development costs, and can meet the engine bay layout requirements of both longitudinally mounted rear-wheel drive and transversely mounted front-wheel drive vehicles. It also boasts good vehicle adaptability, high degree of commonality of engine bay components, and further reduces overall vehicle development costs.

[0037] Please see Figure 8 The vehicle of the present invention uses the above-mentioned engine, which makes the engine compartment components more common and reduces the overall vehicle development cost; the engine assembly can be arranged longitudinally and installed at the rear of the vehicle, or it can be arranged laterally and installed at the front of the vehicle.

[0038] In another implementation, please refer to Figures 1 to 7 Looking forward from the rear of the engine assembly, the intake side is the left side of the engine assembly, and the exhaust side is the right side. The intake manifold 1-5, throttle body 1-4, fuel rail 1-2, alternator 1-6, compressor 1-7, and oil dipstick 1-3 are located on the intake side. The exhaust gas recirculation cooler 3-2, engine coolant inlet 2-2, engine coolant outlet 2-1, cylinder head 2-5, water pump 1-12, and oil cooler 2-3 are located on the exhaust side. The engine drive train, housing 2-7, water pump belt 1-14, compressor belt 1-11, and electromagnet 1-15 are located at the front of the engine assembly. The rear of the engine assembly is connected to the transmission via crankshaft 3-3. The ignition coil 1-1 and the cylinder head cover 2-6 are arranged on the top of the engine assembly.
