exists and is an alternate of .

No! According to AAR definitions, traction horsepower (THP) is the diesel engine INPUT to the main generator available for traction purposes only (generator, electric motors and gear losses are not taken into consideration). So THP is the gross diesel engine HP less the auxiliary load HP (typically 5% of the diesel engine brake HP, for fan driving and other auxiliary vital equipment). Wheel rim HP is usually 85%+ of the traction HP (in a modern locomotive). Drawbar HP (DBHP) will be somewhat smaller (especially as speed increases) due to locomotive resistance as a vehicle (+ 0.75xTHP at maximum speed for a powerful freight loco.). For example, in a SD90MAC diesel loco., the GM16V265H diesel engine is capable of 6300 BHP, but the locomotive is rated at 6000 THP. The drawbar HP can top 5300 DBHP at low speed.

What does tire rating traction a mean?

Tire Ratings - Traction grades Traction grades are an indication of a tire's ability to stop on wet pavement. A higher graded tire should allow a car to stop on wet roads in a shorter distance than a tire with a lower grade. Traction is graded from highest to lowest as "AA", "A", "B", and "C".

How do you convert Wheel Horsepower to Engine Horsepower?

There are many variables in this but gererally for an automatic car, there is a 22% loss in power from the engine to the wheels and for a manual about an 18% loss. If you made 250 wheel hp in an automatic car you should be around 305 hp at the engine.

Who invented the first diesel locomotive?

\nThe first commercial diesel locomotive was built, by GE, in 1918 for the Jay Street Connecting Railroad in New York. Although not particularly successful, it sparked further interest that led to the construction of a diesel locomotive demonstrator in 1924.

How do you drive diesel locomotive?

It really is quite simple - in the cab you are presented with 5 principle controls: . Throttle . Reverser . Independent brake (Brakes the locomotive only) . Train Brake (Brakes the entire train) . Hand Brake. How to drive: . Place the reverser into the forward position. . Ensure all the ( Full Answer )

Is new cars rated hp at the flywheel or at the rear wheels?

\nAt the crankshaft. Cars made after 1973 are rated in Net Horsepower. Like SAE gross and other brake horsepower protocols, SAE Net hp is measured at the engine's crankshaft, and so does not account for transmission losses. However, the SAE net hp testing protocol calls for standard production-type ( Full Answer )

Why is diesel electric used on locomotives?

Diesel electric is used on locomotives because the diesel electric system is much cleaner and quieter and more efficient than the old steam locomotives.

What is front wheel traction loss called?

There are several words for wheels losing traction; spinning, sliding, drifting, breaking free... If it happens to the front wheels while cornering it'll cause understeer = the car will continue straight forward despite the driver trying to turn.

How do you convert engine horsepower to wheel?

\nYou get the engine horsepower from the manufacturer. They take it off the flywheel. You take wheel horsepower by putting a steel band around the tire. There is a pole attached to the band. The pole extends out a foot or two from the vehicle. A big flat square piece of metal is attached to the end ( Full Answer )

When were diesel locomotives invented?

How do you Convert cc to hp horsepower?

The formula that works best only applies to the small newer normally aspirated (carbureted) 4 cycle engines. The ratios change slightly worse with altitude and slightly better with fuel injection. Most American mowers and the newer 4 cycle outboard motors fit into one of these two formulas:. Typica ( Full Answer )

Does wheel size affect horsepower?

No. It effects the vehicles speed, and how the horsepower is used. It take more energy to move larger wheels, so the vehicle will feel less powerful and because the larger wheels take longer to roll, the vehicle will be slower.
