Encyclopedia
The Maybach HL230 is a water-cooled 60° 23 liter
V12
gasoline
engine
designed by Maybach
. It was used during World War II
in heavy German
tank
s, namely the Panther
, Jagdpanther
, Tiger II
, Jagdtiger
(HL230 P30), and later versions of the Tiger I
and Sturmtiger
(HL230 P45). The engine was a follow-up version of the slightly smaller HL210 that had a displacement
of 21 liters and, unlike the HL230, an aluminium
crankcase
and block. The HL210 was used to equip the first 250 Tiger I tanks built.
The engine has a volume of 23,095 cm³ (approx. 1,925 cm³ per cylinder) and a maximum output of 700 PS
(690 hp, 515 kW) at 3,000 rpm
. Maximum torque
is 1850 Nm at 2,100 rpm. Typical output was 600 PS (592 hp, 441 kW) at 2,500 rpm.
The crankcase and block are made of cast grey iron
. The cylinder head
s are made from cast-iron. The engine weighs 1200 kg and its dimensions are 1000 x 1190 x 1310 mm. Aspiration is provided by four twin-choke Solex
type 52JFF carburettors.
Approximately 9,000 HL230s were produced in total by Maybach, Auto Union
and Daimler-Benz
