engine block introduce

A flow valve is a control valve that can display the instantaneous flow rate in a pipeline network. It adds a display function on the basis of a self operated flow control valve, making the balance adjustment of the pipeline network more convenient and accurate. The working conditions of the cylinder body are very harsh. It needs to withstand the sharp changes in pressure and temperature during the combustion process and the strong friction of the piston movement. Therefore, it should have the following performance: ① sufficient strength and stiffness, small deformation, ensuring the correct position of each moving part, normal operation, and low vibration noise. ② Has good cooling performance, with cooling water jackets around the cylinder barrel to allow the cooling water to carry away heat Wear resistant to ensure sufficient service life of the cylinder block. The upper part of the cylinder block is a parallel cylinder barrel, and the lower part of the cylinder block is the crankcase, which is used to install the crankshaft. It can also be used to install various accessories such as generators and engine supports on the outside. The cylinder block is mostly made of cast iron or aluminum alloy, which has a higher cost but is lightweight and has good cooling performance, and is increasingly widely used. The cylinder block is the framework of the engine, which is the installation foundation of various mechanisms and systems of the engine. It is equipped with all the main parts and accessories of the engine inside and outside, bearing various loads. Therefore, the cylinder block must have sufficient strength and stiffness. The cylinder block is mainly composed of parts such as the cylinder block, crankcase, cylinder head, and cylinder gasket. 1. The cylinder block The cover bolts should be tightened evenly and the fuel supply time should be adjusted correctly. 2. Soft water should be added to the water tank and replaced as little as possible. 3. Diesel engines should avoid working under overload for a long time. 4. When the engine is working and the water tank occasionally runs out of water, the engine should not be immediately turned off. Instead, water should be slowly added at low speed. Cold water should not be added after the engine has heated up. After parking, water should be drained after the water temperature reaches below 40 ℃. Water should not be added immediately when starting in cold winter seasons, Instead, heat the water first and add boiling water. 5. During assembly, check whether each cooling water hole is unobstructed. Regularly clean the cooling system with alkaline solution and promptly remove scale and oil stains. The cylinder is an important component of the diesel engine, and the wear of the cylinder should be minimized as much as possible to improve the performance and service life of the diesel engine)

Installation of the crankshaft in the cylinder block during engine assembly process

Before assembly, engine lubrication is necessary. After major repairs of engine parts, lubrication must be carried out before assembly. Within a few minutes before the engine starts running after reassembly, the system pressure has not yet increased and the oil circuit has not been filled with oil, so the lubrication provided by the lubrication system may be insufficient. Therefore, All parts must be lubricated with engine oil or approved engine refurbishment lubricant before installation. This can prevent engine wear before the lubrication system pressure is fully established. The installation of crankshaft bearings should first install the bearing shells. It is not recommended to lubricate the back of the bearing shells. Do not touch the bearing surface with your hands. Only lubricate the bearing surface in contact with the crankshaft journal. Each bearing liner has a locating protrusion, It should be correctly clamped in the positioning groove on the cylinder block. Install the crankshaft bearing and bearing cover and lubricate the bearing surface with oil or equivalent. Ensure that the oil passage hole in the bearing is aligned with the oil passage in the cylinder block. Place the crankshaft smoothly into the cylinder block, being careful not to touch it. Place the lower bearing shell into the main bearing cover. Ensure that the bearing liner is connected to the bearing cover, And the positioning protrusion is stuck in the positioning groove of the bearing cover. Lubricating the bearing liner. Install the bearing cover according to the direction of the arrow and the markings on the bearing cover. After installing the first bearing cover, rotate the crankshaft to ensure it is not stuck. Install the other bearing cover and tighten according to the specifications. Then rotate the crankshaft to ensure it is not stuck. Do this for each bearing cover. If the bearing cover is stuck, The problem may be on the bearing cover or bearing parts. Remove and inspect the bearing seat for burrs or improper assembly. If no problem is found, the cause may be crankshaft bending or cylinder deformation. When tightening the bearing bolts, alternate tightening the bolts or nuts to ensure that the bearings are properly seated and the bearing shells are properly pressed

Maxus T70 introduce

The interior of SAIC Maxus T70 is rich in layering, fashionable and atmospheric, and more inclined towards a passenger car style. The control console is symmetrical on both sides and covered with a large amount of leather and soft enamel materials, enhancing the texture of the car interior
