Which is rated better diesel or petrol engine?
Each engine is rated better for different things. A petrol engine generally has a higher horsepower than a diesel engine, so acceleration and speed is often better on a petrol engine. Diesel engines tend to rate better with torque, so they are better at pulling heavy loads, which is why diesel engines are used in trucks and locomotives.
How do you rate the power of a car engine?
By the number of horsepower its got.
Why do diesel engines have more torque than horsepower?
The issue is that diesel engines, while they produce a whole lot of torque, cannot rev nearly as high as comparable gasoline engines. And since:horsepower = (torque*engine speed) / 5252If your engine won't rev past 3000 rpm, you'll always have less peak horsepower than torque. As for why they can't rev higher, they're limited by either the burn rate of the fuel per ignition stroke, the mechanical limitations due to the longer piston rods/crank lobes, or both.
What is the method for measuring horsepower when applied to the same engine to produce the lowest rating?
Net Horsepower instead of gross. net measures with all accesories on the engine. or you could rate it at a lower rpm.
Can bad diesel fuel break a valve in a diesel engine?
No. there is minimal liquids that can destroy a valve in a diesel engine. For eg) Highly concentrated phispholic acid ect. Bad diesel fuel will run the performance rate down 50-83%.
What causes slow deceleration on a diesel engine?
Diesel engines do not engine brake like gasoline engines do, so relatively speaking, the rate of deceleration would seem to be slower.
How much horsepower from 302 V8 engine mustang?
230BHP as rate out of magazines. Maximum output unknown by me
Cubic centimeter as related to engine horsepower?
Generally speaking the larger number of CC's you have in an engine , the greater the horsepower will be. Most North American Engines used to all be rated in Cubic inches now we rate them in Cubic Centimeters.
What is the major difference between a petrol car and a diesel one?
The primary difference between a petrol car and diesel car is the consumption rate - diesel and petrol are refined from mineral oil using differing methods. The result is diesel engines having a lower fuel consumption rate than their petrol counterparts when installed in a vehicle of similar mass. CO2 emissions are also lower in a diesel engine than they are in a petrol engine.
What is the difference between brake horsepower and horsepower?
The difference between brake horsepower and horsepower or wheel horsepower, they are the same thing, is that brake horse power is the power produced by the crank. The wheel horsepower is the amount of power delivered to the wheels. Brake horsepower refers to the method used to test the engine. A brake is attached to the engine and used to maintain the engine at a constant RPM at full throttle. The delivered power output is then a simple calculation of RPM times torque. Horse power is based on the average amount of work that a horse could do in a day. It is taken to be 746watts. well you guessed it engine output is also specified in kilowatts so divide by 746 and you have horsepower. As stated above it is all the same thing. There is a difference between advertised horsepower and brake horsepower. Advertised horsepower is what a manufacturer will rate its engine/automobile/machine to produce. Brake horsepower is the actual measured horsepower, for example, of a motor on an engine dynamometer.
How do you convert 12.3 grams per horsepower hour to pounds per hour for a 67 horsepower engine?
The number 12.3 grams per horsepower hour is very low. For a diesel engine, the fuel consumption is about 181 grams (of diesel fuel) per horsepower hour. If the 12.3 gram number were right, you just multiply by 67 and get 824.1 grams per hour, or 0.8241 kilograms, multiply by 2.204 pounds per kilogram and and get about 1.8 pounds per hour. This number is too low, it is about 1/3 of a gallon. So, where does the 12.3 number come from? I am fully qualified to answer this question. Stephen G. Margolis, PhD in Engineering Science silogram@alum.mit.edu Judging by the way the question is asked, I am assuming you are looking to find the emission factor and emission rate on a diesel engine to obtain a permit, rather than determine consumption. If this is the case, convert 12.3 grams(guessing that is the nitrogen oxides output) to .02712 pounds, and that gives your emission factor. Now multiply that by 67hp to get 1.817 pounds per horsepower hour, and that would be your emission rate. Ian, Facility Manager who occassion has to apply for permits
When was Burn Rate created?
Burn Rate was created in 1998.
