Mazda 323 is equipped with the four-cylinder line engine with the water cooling located across the direction of the movement.

Cylinders are built in the block cast from gray cast iron. At repair of the engine, for example, because of strong wear or grooves on a mirror of cylinders cylinders can be chiseled and ground. After that installation of pistons of the bigger repair size is required. In the lower part of the block of cylinders there is a crankshaft leaning on radical bearings. Rods are connected to the crankshaft via sliding bearings. From below on the block of cylinders there is a pallet of a case manufactured of sheet metal or aluminum in which engine oil gathers necessary for lubricant and cooling of the engine.

There are four designs of the head of cylinders made of aluminum. These differences consist in an arrangement, gas distribution and number of valves, and also among cam-shafts.

Models with the diesel engine of 1,7 l (designation of the PN engine) have a head of cylinders with one cam-shaft which sets in motion via the shaking levers 2 valves on the combustion chamber (1 inlet and 1 final valves). The camshaft is set in motion by a gear belt. Inlet and final collectors are established on the one hand heads of cylinders.

Models with petrol engines of 1,1 l, 1,3 l and 1,5 l (designation (E1, EZ, E5) have a head of cylinders, inlet and final channels of which are located opposite, with one cam-shaft which sets in motion through yokes 2 valves on the combustion chamber (1 inlet and 1 final valve). The camshaft is set in motion by a chain.

Models with petrol engines of 1,4 l, 1,5 l, 1,6 l and 1,9 l (designation VZ, V5, B6 SOHC, BPE SOHC) have a head of cylinders with an opposite arrangement of inlet and final collectors with one cam-shaft. The camshaft, depending on model, puts in action through yokes 2 or 4 valves on the combustion chamber (2 inlet and 2 final valves). The cam-shaft is set in motion by a gear belt. Cars with petrol engines 1,6 or 1,9 of l (designation B6 DOHC, BP DOHC) also have a head of cylinders with an opposite arrangement of inlet and final channels, but with two cam-shafts. They set in motion through dish-shaped pushers 4 valves on each combustion chamber (2 inlet and 2 final valves). Cam-shafts are set in motion by one gear belt.

In engines with a head of cylinders with an opposite arrangement of inlet and final channels fresh fuel-air mix enters on the one hand heads, and the fulfilled gases are produced from opposite. At the expense of such arrangement more bystry gas exchange and high power is provided.

For lubricant of the engine the oil pump which or is located on the forward party of a case serves, or is in the case pallet (engine E). It is put in action directly from the crankshaft or through a chain. Podsasyvayemy oil arrives through openings and channels to bearings of cranked and distributive shaft, and also to a mirror of cylinders.

The water pump on VZ, V5, B6, BP and PN engines is located at an end face of the block of cylinders. On engines E water pump is on the block of cylinders sideways. The pump drive on all engines is carried out by a maple belt which also puts the generator in action. One or two additional maple belts serve for the drive of the amplifier of steering and the conditioner. For preparation of working mix depending on model either the carburetor, or electronic system of injection of fuel which, as a rule, does not demand maintenance serve.

Sparks of ignition are developed by unattended electronic system of ignition. Depending on model, perhaps, check and adjustment of the moment of ignition within maintenance is required. The distributor of ignition is located on a head of cylinders and is put in action directly by a cam-shaft.

The radiator fan at the switched-off engine and the included ignition can spontaneously turn on. In a motive compartment it can happen because of heat several times. During the works in a motive compartment on the hot engine it is necessary to remember possible turning on of the fan always. Therefore during the works in a motive compartment ignition should be disconnected whenever possible.
