How to work the truck engine accessories

The main accessories of truck engines and their working principles include the following key parts:

‌Pipheral and cylinder‌: The piston moves up and down in the cylinder, and completes a working cycle through four strokes: intake, compression, work and exhaust. During the intake stroke, the piston moves downward, the intake valve opens, and the air and fuel mixture enters the cylinder; during the compression stroke, the piston moves upward, compressing the mixture; during the work stroke, the spark plug ignites the mixture, producing high-temperature and high-pressure gas to push the piston downward; during the exhaust stroke, the piston moves upward, exhausting exhaust gas.

‌Crankshaft and connecting rod: One end of the connecting rod is connected to the piston and the other end is connected to the crankshaft. The up and down movement of the piston is converted into the rotational movement of the crankshaft through the connecting rod, thereby driving the engine to operate.

‌Intake Manifold and Fuel Injector‌: The intake manifold distributes air to each cylinder, and the fuel injects fuel into the cylinder and mixes with air. The mixture burns in the cylinder to generate power.

‌Valve and Camshaft‌: The valve is controlled to open and close by the camshaft. The camshaft is connected to the crankshaft through a timing belt or timing chain to ensure that the opening and closing of the valve is synchronized with the movement of the piston.

‌Cylinder head and cylinder block: The cylinder block is the foundation of the engine. The cylinder head closes the upper part of the cylinder to form a combustion chamber. There is a water jacket in the cylinder body for cooling, and there are inlet and exhaust passages, spark plug holes, etc. on the cylinder head.

‌Flywheel‌: The flywheel stores energy and helps the engine run smoothly. When the engine speed changes, the flywheel can provide or absorb energy to ensure smooth engine operation.

These accessories work together to convert the chemical energy of the fuel into mechanical energy, driving the car forward. Hyundai Motor Engines are also equipped with electronic control systems such as fuel injection systems and ignition systems to accurately control fuel supply and ignition timing, improve efficiency and reduce emissions.
