TheH family is a line ofautomobile 60°V6 engines fromSuzuki. Ranging in displacement from 2.0 to 2.7 L (1,998 to 2,736 cc), the H family was a modern all-aluminum engine withdual overhead cams, 24 valves, andmulti-port fuel injection. It was co-developed withMazda andToyota, which used a similar design in their2.0 L KF V6 and theToyota VZ engine. The H family was introduced in 1994 with the H20, but Suzuki, Toyota and Mazda's designs diverged greatly with the former increasing displacement and the latter experimenting with alternative induction technologies and smaller engine sizes. The four-cylinderJ engine, which appeared in 1996, shared parts and design with the H family.[1]
The H20A displaces 2.0 L (1,998 cc); bore and stroke is 78 mm × 69.7 mm (3.07 in × 2.74 in). With a 9.5:1 compression ratio, it produces 107 kW (145 PS; 143 hp) at 6,500 rpm and 172 N⋅m (127 lb⋅ft) at 4,000 rpm.[2]
Applications:
The H25A displaces 2.5 L (2,495 cc); bore and stroke is 84 mm × 75 mm (3.31 in × 2.95 in) and produced 106 kW (144 PS; 142 hp) when first introduced.[3] With a 9.5:1 compression ratio, it produced 106 kW (144 PS; 142 hp) at 6,500 rpm and 203 N⋅m (150 lb⋅ft) at 3,500 rpm on its introduction, with a 2001 update increasing this to 116 kW (158 PS; 156 hp) and 213 N⋅m (157 lb⋅ft).[4] It is also being considered and used for various ultra-light aircraft propulsion systems, like theTitan T-51 Mustang.
Applications:
The H27A is a modern version of the H25A, displacing 2.7 L (2,736 cc), coming from an 88 mm × 75 mm (3.46 in × 2.95 in) bore and stroke (VVT added in 2006). The engine is tuned to achieve most of its torque at low revs at the expense of raw power at high revs, making the engine very responsive in day-to-day driving. It produces 138 kW (188 PS; 185 hp) at 6,000 rpm and 250 N⋅m (184 lb⋅ft) at 3,300 rpm.[4]
