In addition, all parts need to be cleaned and inspected to ensure that they are clean, complete and compliant. At the same time, it is also necessary to prepare the assembly engine workbench, work lights and personal protective equipment.Step 2: Assembling the cylinder block and cylinder head. The first step to assemble the engine is to assemble the cylinder block and cylinder head. First of all, pistons and connecting rod components need to be installed. Then, it is necessary to place the cylinder head on the cylinder block and install all the necessary spare parts (such as intake manifold, exhaust pipe, ignition line, etc.) on the cylinder head. Next, you need to install the camshaft and camshaft gears, and install the rocker arm and valve in the correct order. Step 3: After the second step of installing the crankshaft, you need to place the crankshaft on the cylinder block and connect the connecting rod assembly to the crankshaft. At this time, it is necessary to ensure that the crankshaft bearing is installed correctly, and all bolts and screws need to be tightened correctly according to the specifications with a torque wrench.

In this step, you need to place the accessories on the engine and connect them to the engine with the correct bolts. To sum up, the car engine is the core part of the car, and its assembly requires energy and patience. As we can see, the assembly process of car engines is very complicated, from preparation to the installation of the last spare part, every step needs to be carefully carried out.Therefore, when assembling the engine, it must be ensured that each spare part is installed correctly, and appropriate tests and adjustments are needed to ensure that the engine is running normally.
