A chassis dynamometer.. A dynamometer or "dyno" is a device for simultaneously measuring the torque and rotational speed of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp.
An alternate mechanism is to clamp a lever to the shaft and measure using a single balance. The torque is then related to the lever length, shaft diameter and measured force. The device is generally used over a range of engine speeds to obtain power and torque curves for the engine, since there is a non-linear relationship between torque and ...
Speed has dropped out of the equation, and the only variables are the torque and displacement volume. Since the range of maximum brake mean effective pressures for good engine designs is well established, we now have a displacement-independent measure of the torque-producing capacity of an engine design – a specific torque of sorts.
The engine was fed by just two carburettors and developed a claimed 245 bhp (183 kW; 248 PS) gross at 5,500 rpm, [5] which was 20 bhp (15 kW; 20 PS) less than the triple-carburettor version in the 420G and E-Type. The maximum torque of the engine at 283 lb⋅ft (384 N⋅m) was virtually the same as that of the triple-carburettor version yet was ...
There are many different standards and types of horsepower. Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about 745.7 watts, and the metric horsepower as in "cv" or "PS" which is approximately 735.5 watts. The electric horsepower "hpE" is exactly 746 watts, while the boiler horsepower is 9809.5 or ...
It produced 130 bhp (97 kW) as opposed to the Flathead's final 110 bhp (82 kW), an increase of 18%. [1] The Mercury Y-Block was 256 cu in (4,194 cc) and produced 161 bhp (120 kW), [ 3 ] again a similar displacement to the 255 cu in (4.2 L) Mercury Flathead V8 it replaced, but with 29% more power than the older engine's 125 bhp (93 kW).
As industrial engine, its rated power is 22.8 kW (31 PS; 31 bhp) at 3000 min −1 without a governor, the highest torque 81.4 N⋅m (60 lbf⋅ft) at 2000 min −1. With a governor set to 8% accuracy, the rated power is 21.33 kW (29 bhp; 29 PS) at 3000 min −1, the highest torque is 69.63 N⋅m (51 lbf⋅ft) at 2000 min −1. [4]
In the D22 Navara/Kingcab/Frontier the engine is essentially the same other than modifications to accessories, mounts and plumbing to accommodate the longitudinal engine layout. The turbo is a wastegated IHI RHF4 which is also intercooled. The stronger gearbox allows it to produce more torque than the Presage/Bassara version.
