What is the difference between a D16 engine and D17 engine?

D16 Engine

* Displacement: 1.6 liters

* Bore: 75.0 mm (2.95 in)

* Stroke: 90.0 mm (3.54 in)

* Compression ratio: 9.6:1

* Power: 110 hp (82 kW) @ 6000 rpm

* Torque: 106 lb-ft (144 N-m) @ 5000 rpm

* VTEC: No

D17 Engine

* Displacement: 1.7 liters

* Bore: 76.0 mm (2.99 in)

* Stroke: 89.0 mm (3.50 in)

* Compression ratio: 10.0:1

* Power: 125 hp (93 kW) @ 6500 rpm

* Torque: 111 lb-ft (150 N-m) @ 5000 rpm

* VTEC: Yes

Differences

The main differences between the D16 and D17 engines are:

* The D17 has a larger displacement than the D16.

* The D17 has a higher compression ratio than the D16.

* The D17 has VTEC, which increases power and torque at higher RPMs.

As a result of these differences, the D17 engine produces more power and torque than the D16 engine. However, the D16 engine is more fuel-efficient than the D17 engine.
