What are the main features of the engine oil san design?

1. The oil pan shell is mostly stamped by thin steel plates.The interior is equipped with a stabilized oil baffle to avoid the right side shock and splash caused by the bump of the diesel engine, which is conducive to the precipitation of lubricating oil impurities. The side is equipped with an oil ruler to check the amount of oil. In addition, the bottom of the oil span is also equipped with an oil release screw plug. The oil span can be divided into wet and dry.

2. However, in engines with dry oil span, the intensity of this pressure lubrication is much greater. In addition, the size of the engine oil pump must be much larger than that of the wet oil sump engine. When using, the engine oil pump needs a little more power. Just like a supercharged engine, the oil pump consumes part of the power of the engine.

3. The cylinder head of the modern car engine is made of aluminum alloy. The cylinder head is a complex and important casting part. The combustion chamber, the intake pipe and exhaust pipe of the engine are all installed in the cylinder head.

Figure 1 Automobile Engine 1 Engine The basic structure (1) Crank connecting rod mechanism The crank connecting rod mechanism is composed of three parts: the fuselage group, the piston connecting rod group and the crankshaft flywheel group. Its function is to burn the fuel.The heat energy produced is transformed into the rotational motion of the crankshaft through the linear reciprocating motion of the piston to output power through the flywheel.

The adjacent cylinders of the horizontally opposed engine are arranged against each other (the bottom of the piston is outward), and the angle between the two cylinders is 180°, but it is still essentially different from the 180°V engine.

Car engine: The engine is the power unit of the car. It consists of 2 major mechanisms and 5 major systems: crank connecting rod mechanism; gas distribution mechanism; fuel supply system; cooling system; lubrication system; ignition system; start system. Cooling system: generally composed of water tank, water pump, radiator, fan, thermoster, water temperature gauge and water release switch.

Car Maintenance Knowledge Engine Chapter Use appropriate quality grade of lubricating oil. For gasoline engines, SD-SF-level gasoline oil should be selected according to the additional devices and working conditions of the intake and exhaust system;For diesel engines, CB-CD-grade diesel oil should be selected according to the mechanical load. The requirements not lower than those stipulated by the manufacturer shall prevail.

Fuselage group, composition: cylinder head, cylinder block and crankcase Function: As the assembly base of various engine mechanisms and systems, it is the skeleton that supports and fixes the crank connecting rod mechanism and other devices, and the relevant parts of the tractor chassis form the frame of the tractor.

Automobile Trivia | Engine Start-up Condition Check Purpose of Inspection: The causes of failures related to engine start-up are different, depending on whether internal combustion occurs or whether the start-up takes a lot of time. Therefore, check the starting status of the engine to determine the cause of the failure. Inspection method: Start the engine to check the engine start-up status.

The purpose and significance of high-altitude engine structural reliability design

The purpose and significance of high-altitude engine structural reliability design are as follows: the purpose of structural design is to enable the designed structure to meet various predetermined functional requirements. Structural reliability refers to the probability that the engineering structure will complete the predetermined function under the specified time and conditions, which is the probability measure of the reliability of the engineering structure.

The main significance of this design is to improve the performance and stability of the engine, enhance the reliability of the engine, reduce maintenance costs, etc. To improve the performance and stability of the engine, through reasonable structural design, it can effectively improve the performance and stability of the engine, reduce the probability of failure, and improve the service life of the engine.

Purpose: The reliability design of aircraft structure is an important part of the aviation field, the purpose of which is to ensure the safety of crew and passengers. Significance: It will be more reasonable to determine the reliability quantitative indicators through functional safety design, troubleshooting and fault tolerance design, as well as material and structural design.

Question 2: The importance of reliability design Reliability design is an important part of the overall engineering design of the system. It is a series of analysis and design techniques to ensure the reliability of the system. It is realized through the circuit design and structural design of the system.

The high thrust-to-weight ratio promotes the refinement of the structural design of the aviation engine. It is necessary to adopt advanced technologies such as the overall blade disc and leaf ring structure to reduce the weight of the corresponding parts, improve the performance of components such as fans, compressors and turbines, extend the service life and improve reliability.
