Toyota 3L Engine Specifications
The Toyota 3L is a 2.8 L (2,779 cc, 169.6 cubic inches) four cylinders,
4-stroke water-cooled naturally aspirated internal combustion diesel
engine, manufactured by the Toyota Motor Corporation.
The Toyota 3L diesel engine has a 96.0 mm (3.78 in) cylinder bore and
96.0 mm (3.78 in) piston stroke. Compression ratio rating is 22.2. The
motor has a cast iron cylinder head with a single overhead camshaft
(SOHC) with two valves per cylinder and indirect injection design.
