ZMZ-24 is an inline four-cylinder gasoline carbureted overhead-valve (OHV) engine with a displacement of 2.4 liters, designed and produced by the Zavolzhye Motor Plant (ZMZ, Zavolzhsk, Ivanovo Region). It is one of the most widely produced automobile engines in the history of Soviet and Russian automaking.[1]
Design and specifications
The engine follows the OHV layout, with the camshaft located low in the block and eight valves. Fuel is supplied through a carburetor. The maximum output of the base version is 95 hp (70 kW), and the unit weighs about 180 kg.[1]
Place in the ZMZ family
The ZMZ-24 is the direct successor of the ZMZ-21 engine (also known as the GAZ-21), created in the 1950s, and the predecessor of the ZMZ-402 series, which was a thorough modernization of it. The ZMZ-24 line includes several variants; within the family it also covers the ZMZ-24D versions. Further development produced the ZMZ-402 series engines (including the ZMZ-402.10, ZMZ-4021.10, ZMZ-4021.17, and ZMZ-4021.19 modifications) with an output of 90–100 hp, as well as the modern ZMZ-1402.10 with a stated output of 95 hp, which retains the same OHV architecture.[1]
Nizhny Novgorod connection
ZMZ-24 series engines were installed primarily in the Volga GAZ-24 cars built by the Gorky Automobile Plant (GAZ) in Gorky (Nizhny Novgorod) from 1970 to 1992. The engine and the car thus formed a single production and engineering chain: GAZ built the body and chassis, and the Zavolzhye Motor Plant built the powertrain. The GAZ-24 Volga became the most widely produced Volga car in the history of the family, and the ZMZ-24 engine was an integral part of it throughout that period.[1]
