The ZMZ-523 carburetor engine has been produced since 1963 and was installed mainly on PAZ buses. It is simple in design, but has an increased fuel consumption.
Russia is considering the possibility of resuming the production of gasoline engines of the ZMZ-523 family. They were developed in the early 60s. This is reported by the site Quto.ru.
The ZMZ-523 engine has been produced at the Zavolzhsky Motor Plant since 1963. This 4.7-liter carburetor V8 was a slightly modified version of the ZMZ-53 engine, created in the second half of the 50s.
Eight with a capacity of 128-138 hp. With. installed on GAZ-3308 trucks and PAZ-3205 buses. The archaic engine has a simple design, but it has a very high fuel consumption.
In 2021, the production of the obsolete V8 was stopped and about 6.5 million engines were assembled in total. However, now, under the sanctions in the Russian Federation, the supply of a number of imported engines has been stopped, and the lack of foreign components makes it impossible to produce more modern Russian engines.
The Zavolzhsky Motor Plant believes that the old ZMZ-523 will be in demand. They say that carriers using PAZ buses are interested in resuming its production. Engine production can be launched in 2023 in gasoline and gas versions.
