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.

What is the horsepower of the 7.3 powerstroke diesel?

This is the Very First powerstroke. The legendary 7.3, when it first came to the dealers in the second half of 1994 it was packing 235 horsepower. Don't get confused about the previous 7.3s they are not the same. The previous 7.3 was a mechanical injection. The POWERSTROKE 7.3 had an computer. In 1999 they brought up the Power to 250 for automatics and 275 for Manuals. Then in the second half of 2003 the 7.3 was no longer availabe due to higher emmision standards then the 6.0L came into production. Then again in the 2008 model year the 6.0l was choked out and the 6.4l came into production and that was killed in the 2011 model year for the 6.7 to take over.

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 brakes are off. . Put a small amount of throttle on to make the train move. To stop: . Put the independent brake and train brake on. . When you have come to a halt, disengage both brakes, put the reverser back into neutral, and apply the handbrake.

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 belt-driven accessories, air cleaner, emission controls, exhaust system, and other power-consuming accessories. This produces ratings in closer alignment with the power produced by the engine as it is actually configured and sold. A car put on a Dyno will be rated at the rear wheels, but new cars are not tested on a Dyno.

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. The diesel fuel is used to run a generator which produces electric power which is used to power the electromagnetic drive motors mounted on the locomotives axles!

How much horsepower does a 04 Duramax Diesel have?

depends on which engine you have. 2004 was the transition year. look at the eighth digit in your vin # if its a "1" you have a LB7, if its a "2" you have a LLY.. LB7 300hp 520ft tq. LLY 310hp 605ft tq

What is the horsepower of the 6.0 liter powerstroke diesel?

325 600 tourque ----------------------------------------------------------------------------------------------------- Improved Answer By: AP_MET Horsepower is just a broad term denoting 745.7 Watts of power output of any type of mechanical or electrical device. Foot-Lbs (or Newton-Meters) Torque output at a specific RPM is the true factor in rating a piston engine's performance. Piston engine horsepower and torque cannot be measured by engine displacement alone. On piston engines, there are three (3) types of horsepower: Indicated Horsepower (IHP) = Theoretical horsepower of an entire piston engine at a given RPM. Brake Horsepower (BHP) = Useful crankshaft horsepower of a piston engine at a given RPM. Friction Horsepower (FHP) = Horsepower needed to keep a piston engine running at a given RPM. IHP = BHP + FHP. Take for instance: A 2003 Ford Super-Duty F250 Pickup Truck powered by a 6.0 Liter "Powerstroke" 4-Stroke, 8-Cylinder V-8 Diesel Piston Engine with the following specifications: Engine: Powerstroke 6.0 Liter (366.14 ci) V-8 / Diesel Piston Bore Diameter: 3.74 inches (10.99 sq. in.) Piston Stroke Length: 4.13 inches (0.344 ft.) Maximum Torque Output: 570 Foot-Lbs @ 2,000 RPM (1,000 pws/min - 4-stroke) Compression Ratio: 18:1 BMEP - 4-stroke = [(150.8 x 570) / (366.14)] = 234.76 PSI. BHP = [(234.76 x 0.344 x 10.99 x 1,000 x 8) / (33,000)] = 215.16 BHP. This particular automotive 4-stroke, 8-cylinder diesel piston engine will develop a crankshaft Brake Horsepower of 215.16 BHP at 2,000 RPM while at its maximum crankshaft Torque output rating of 570 Foot-Lbs. The higher internal cylinder pressures of diesel piston engines give them a very high torque output at their crankshaft at a much lower RPM and Brake Horsepower compared to gasoline piston engines. -------------------End Improved Wiki Answer------------------

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 of the pole. That piece of metal is put on a scale. That way a shop figures out wheel horsepower. The conversion shows that about 50% of the power at the flywheel makes it to the wheels. Since electric generators and motors have greater than 90% efficiency, conversion to gasoline-electric vehicles could theoretically double mileage.

When were diesel locomotives invented?

The world's first diesel-powered locomotive was operated in thesummer of 1912 on the Winterthur-Romanshorn Railroad inSwitzerland, but was not a commercial success.

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:. Typical new carbureted engine well tuned:. 1 x HP per each 25 cc . Fuel injected:. 1 x HP per each 22 cc . Notes: . - Most engines are tuned down to a lower HP for better engine life.. - It is common for the same cc engine to be built in 3 different HP versions with the highest rated being the maximized HP per cc version. That is how you see price and HP changes on the same cc engine made by the same company.. -Some of the newest (2008 and newer) engines from Japan perform slightly better (10-20%).. A typical 150cc motor should equate to between 3.5 - 6 HP+ depending on tuning with 5 HP being the adv. . A Typical 1200cc Motor should produce between 50 - 75 HP depending on tuning.. Max/High Performance engines for motorcycles and racing do not fit these formuls and can vary up to double and more. These are standard use numbers. The actual formula plots as a curve and is not a fixed linear formula.

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.

Is diesel oil and diesel the same?

Diesel fuel is often referred to as "diesel oil" or "heavy oil". Do not confuse this with "engine oil for a diesel engine" which means "lubricating oil specially formulated for use in diesel engines". My first Ford Fiesta diesel's tax disc said - "Fuel - Heavy Oil". They've now realised that this term is anachronistic, and my latest tax disc reads "Fuel - Diesel". To be pedantic - Diesel fuel is an oil - Petrol is a spirit.

Why diesel engine is not used in small locomotives?

I am not an expert but my understanding is the electromotiveconfiguration is better suited to locomotives. An internalcombustion engine is used to run a generator or alternator and theelectricity then runs the electric motors that drive thewheels. . +++ The diesel engine IS used in small locomotives, usually with ahydraulic transmission. Larger locomotives use either electric orhydraulic drives but the prime mover is still a diesel engine.

Two wheel drive traction in snow?

Throw something heavy in the bed of a truck, or trunk of a car. Just put enough in so your front bumper remains level or slightly above level with your back bumper. That way you have down force on your rear and retain steering control. This works well for trucks and rear wheel drive cars. I'm aware of that, but it has heavy duty supension, I addes 400 lbs, with good tires and it has posi=traction, still to light in the rear end, is there anything else to do.

Can traction free locomotive be built?

Wow i just won my 8th grade science fair with this very subject here is some info i still have saved to my computer. Maglev, or Magnetic levitation , is a system of transportation that suspends, guides and propels vehicles, predominantly trains, using magnetic levitation from a very large number of magnets for lift and propulsion. This method has the potential to be faster, quieter and smoother than wheeled mass transit systems. The power needed for levitation is usually not a particularly large percentage of the overall consumption; most of the power used is needed to overcome air drag , as with any other high speed train.

What are advantages and disadvantages of diesel locomotive?
