Isuzu 6HH1 Truck Engine Specifications
by David WeedmarkIsuzu 6HH1 engines are found in Isuzu F Series medium-duty commercial trucks. The F Series trucks can be recognized by their wide windows and a cab-over design that puts the driver above the engine. These trucks can be used as open-bed or closed-panel freighters, or as tippers. While larger F Series models produced in 2010 have three axles, those with the 6HH1 engines all have two.
6HH1 Engine Specs
The 6HH1 Isuzu diesel engine is a six-cylinder engine with an overhead cam. It uses direct ignition for its in-line cylinders and is water-cooled. The bore and stroke are 4.5 by 5.2 inches. It has an 18.5 to 1 compression ratio.
6HH1 Variations
Isuzu produces two models of the 6HH1 engine, the 6HH1-N and the 6HH1-S. Both engines are the same size, with the same specs listed above, but the S model has a bit more power than the N. The 6HH1-S has a maximum output of 195 horsepower at 2,850 rpm, and a maximum torque of 369 foot-pounds at 1,700 rpm. The 6HH1-N has a maximum output of 173 horsepower at 2,800 rpm, and maximum torque of 340 foot-pounds at 1,700 rpm.
F Series Trucks
Isuzu F Series trucks with the 6HH1 engine have many specifications in common, including a two-wheel-drive, six-speed manual transmission with a hydraulic clutch. They use air-over hydraulic dual circuit brakes, with auxiliary exhaust brakes. The F Series trucks seat three, with a cab that tilts forward to access the engine. Safety features that come standard include side-impact beams on the driver's side and passenger doors, three-point side mirrors, and fog lamps beside the headlights. The cabs also feature a telescopic tilt steering column and power steering. The FSR model weighs 11 tons and can haul a payload of 8 tons, while the FTR weighs 14.2 tons and can carry a load up to 11 tons.
