Isuzu KB P190. Manual

The HFV6 engine features a closed vee, deep skirt die cast aluminium cylinder block with cast iron cylinder liners,
internally balanced crankcase, full length water jackets and six bolt main bearing caps.

The cylinders are arranged in two banks of three with a 60 degree included angle between the two banks.

The right-hand bank of cylinders consists of number 1-3-5
cylinders and the left-hand bank of cylinders consists of
number 2-4-6.

The engine firing order is 1-2-3-4-5-6.

Each aluminium cylinder head is fitted with hardened valve
seats and four valves per cylinder: two intake and two
exhaust.

The valves are operated by two camshafts (DOHC) per
cylinder bank, one each for intake and exhaust valves.

The crankshaft is manufactured from forged steel. A reluctor
wheel is pressed in place onto the rear of the crankshaft for
the crankshaft position sensor.

The connecting rods are manufactured from powdered
metal and the rod cap is separated during the manufacturing
process using the fractured method. This creates a stronger,
visually seamless rod to cap union.
