KAMAZ 820 is a family of 4-stroke V-shaped 8-cylinder liquid-cooled gas engines, turbocharged with charge air cooling, with spark contactless ignition, with an electronic control system for distributed gas injection using electromagnetic dispensers manufactured by KAMAZ PJSC.
The Kama Automobile Plant specializes in the production of trucks that have become legendary, but in a small range it also produces diesel and gas engines. KamAZ motors are installed on KamAZ vehicles, LIAZ buses, NEFAZ buses, KamAZ tractors, as well as on stationary diesel installations.
KamAZ-740 engines are mainly installed on KamAZ production equipment. This is a V8 engine with a working volume of 11.7 liters, which during its production has evolved from Euro-0 to Euro-5.
On its basis, a KamAZ-820 gas power plant was created.
In addition to its own engines, KamAZ uses in-line 6-cylinder 6.7-liter Cummins ISBe6.7 diesel engines in production. Also used Cummins B5.9 (volume 5.9 liters with 6 cylinders), 8.9-liter 6-cylinder Cummins ISL400 and 11.8-liter Cummins ISG12, which also has 6 cylinders in a row.
German engines with in-line 6-cylinder configuration Mercedes-Benz OM457LA, which has a working volume of 12 liters, are also installed on Kamaz.
Buses also use Chinese in-line 7.5-liter 6-cylinder Weichai WP7NG and 4-cylinder Weichai WP4.1NG with a volume of 4.1 liters.
KamAZ trucks began to be built in 1969. For the new generation of trucks, engineers have created a 4-stroke diesel 8-cylinder KamAZ-740 V8 engine. This power unit had a displacement of 10852 cm3, and its power was 210 horsepower. Then the power ratings had to be expanded from 180 to 360 hp.
The 12-liter OM 457 engine series includes 3 powerful and economical engines – 315 kW (428 HP), 295 kW (401 HP) and 260 kW (354 HP) The OM457LA engine complies with the EURO emission class -five. It has an excellent balance of high power, fuel efficiency and motor life, reaching 1 million km.
