Asked Questions
The function of engine cylinder is to provide the installation of various engines and their components, support the working positions of moving parts such as pistons, connecting rods and crankshafts, and ventilate, cool and lubricate the engines.
Introduction of engine cylinder block
The material of engine cylinder block is generally gray iron, such as HT200 and HT250. Because the working environment of the cylinder block is humid (working under the immersion of gasoline), and it has high temperature, high load and intense friction. Therefore, the cylinder body is required to have high strength, high hardness, high wear resistance and good heat dissipation, while gray iron can meet the requirements of high strength, hardness and high wear resistance, and has excellent technological performance, vibration damping and cutting performance, and low cost, but the disadvantage is that it is heavy. So now more and more cylinder blocks are made of aluminum alloy, because its advantage is to reduce the weight of the cylinder block, which also conforms to the trend of automobile lightweight.
According to the different positions of the installation plane of the cylinder block and the oil pan, the cylinder block is usually divided into the following three forms:
(1) General cylinder block: It is characterized in that the installation plane of oil pan and the rotation center of crankshaft are at the same height.
(2) Gantry cylinder block: It is characterized in that the installation plane of oil pan is lower than the rotation center of crankshaft.
(3) Tunnel-type cylinder block: The main bearing hole of the crankshaft of this type of cylinder block is integral, with rolling bearings. The main bearing hole is larger, and the crankshaft is loaded from the rear of the cylinder block.
