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

Cylinders are built in the block cast from gray cast iron. At engine repair, 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 made of sheet metal or aluminum a case pallet in which engine oil gathers necessary for greasing and engine cooling.

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

Models with the diesel engine of 1,7 l (PN engine designation) have a head of cylinders with one cam-shaft which actuates via shaking levers on 2 valves on the combustion chamber (1 inlet and 1 final valves). The camshaft is actuated 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 (designations (Е1, EZ, Е5) have a head of cylinders, inlet and which final channels are located opposite, with one cam-shaft which actuates through yokes on 2 valves on the combustion chamber (1 inlet and 1 final valve). The camshaft is actuated by a chain.

Models with petrol engines of 1,4 l, 1,5 l, 1,6 l and 1,9 l (VZ designations, В5, 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 actuated by a gear belt. Cars with petrol engines 1,6 or 1,9 of l (designation of 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 actuate through tarelchaty pushers 4 valves on each chamber of combustion (2 inlet and 2 final valves). Cam-shafts are actuated by one gear belt.

In engines with a head of cylinders with an opposite arrangement of inlet and final channels the fresh toplivovozdushny mix enters on the one hand heads, and the fulfilled gases are issued from the opposite. At the expense of such arrangement faster gas exchange and high capacity is provided.

For greasing of the engine the oil pump which or is located on the forward party of a case serves, or there is in the case pallet (engine E). It is put in action directly from the crankshaft or through a chain. Podsasyvayemoye 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 engines, В5, B6, and PN is located VR at an end face of the block of cylinders. On engines E the 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 in action the generator. One or two additional maple belts serve for a drive of the amplifier of a steering and the conditioner. For preparation of a working mix depending on model serve either the carburetor, or electronic system of injection of fuel which, as a rule, does not demand maintenance.

Sparks of ignition are developed by unattended electronic system of ignition. Depending on model, probably, 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 by directly cam-shaft.
