Why petrol engine is called spark ignition engine?

Because the fuel is ignited by a spark plug rather than by compression as is the case with a diesel.

What is difference between partial factor of safety and factor of safety?

A safety factor is an aspect of design that increases strength or protection beyond that suggested as needed by calculation or other basic assessment. For example, engineering calculations might suggest a bridge needs a certain amount of strength in a support beam. That number would be increased by, perhaps, 20% as a "safety factor" in case it were to be stressed beyond its design or in case some basis for the calculation was in error.A partial safety factor is one of several safety factors applied to the same instance.

What is the symbol of power factor?

There is no SI symbol, as such, for power factor. As power factor is the cosine of the phase angle (the angle by which the load current leads or lags the supply voltage), power factor is normally written as 'cos' followed by the lower-case Greek letter we pronounce 'phi' (I've no idea how to type a Greek letter in this answer!).

How do you find whether it is inductor or capacitor if only power factor is given?

in case of inductor or capacitor power factor is always zero.as power factor is cosine of phase angle between voltage and current. in case of inductor and capacitor phase angle between voltage and current is 90 so it become zero so if given power factor is zero then it can be inductor or capacitor.

Can be the power factor become negative reading?

Yes, power factor can be negative. That is the case of a generator. Power factor is the cosine of the phase angle between voltage and current, and the cosine can be positive or negative.AnswerNo. Power factor can be 'leading' or 'lagging', but it cannot be 'negative' or 'positive'.

What do diesel trains run on?

Diesel trains are powered by diesel engines that are connected to generators that then drive electrical motors which are connected to the driving wheels. Some steam engines were also outfitted to run on diesel. in that case the diesel heated water which went into a reciprocating (moves back and forth)cylinder which then drove the wheels that drove the train.

Why petrol cost is high and diesel cost is low?

That is not necessarily the case nowadays. Diesel fuel was much cheaper because there were far fewer cars with diesel engines. Since many more cars have diesel engines now the various governments increased the tax on diesel fuel to increase the revenue it receives. As did the fuel companies to to a far lesser extent. Diesel fuel is almost always higher than gasoline. Reason being is the EPA regulations a few years back regulated that diesel be made much cleaner that it was in the past. It costs more to refine this clean diesel. Have you noticed that you do not see black smoke bellowing from diesel trucks anymore.

Does kenwoth have on board fault code diagnostics?

Pretty much any truck from 1993 onwards does... in the case of those with the Detroit Diesel 60 Series engines, any one from 1986 to 2002 will (Detroit Diesel became exclusive to Daimler products after that year).

What engine does a school bus have?

Really depends on the type. A Type A school bus might have a gas, diesel, or CNG engine.. those will use whatever is standard for the chassis manufacturer (e.g., Triton gas or Powerstroke diesel for Ford chassis, Vortec gas or Duramax diesel for General Motors chassis, Hemi gas or Cummins diesel for Dodge chassis). For Type B, C, and D buses, Thomas Built buses is owned by Daimler A.G. - the parent company of Freightliner, Western Star, and Mercedes Benz, and have been available with Cummins, Mercedes-Benz, or Caterpillar (until 2009) diesel engines or Cummins CNG engines. IC Bus is a subsidiary of Navistar International, and can have Navistar MaxxForce or Cummins diesel engines, or Cummins CNG engines. Blue Bird does not make their own engines, so they will use Cummins diesel or CNG engines. In the case of diesels, 6 - 7 liters is most likely what you'll find, though I have, in the past, seen school buses with 7.3 liter 3126 and C7 Caterpillars.

What does an engine tattoo mean?

My bet is you are reading something that is describing the sound of an engine or engines, probably diesel, running off in the distance. In that case, tattoo would be a synonym for drumming sound.

Why are submarines hybrids?

All submarines have at least 2 methods of propulsion; with nuclear power, steam generated moves the turbines/main engines, and also makes electricity for battery storage in case of main propulsion failure (electric motor propulsion). A backup Diesel-Generator is also aboard for making electricity if the reactor is down. Diesel-Electric boats run on electric motors (battery powered) submerged, and on their diesel engines while surfaced.

Can Low Running Harm Diesel Engines?

nothing like that , but people which have low running go for petrol because , the price difference between them more than one lack . in the case of diesel engine it get good milage and efficiency at optimum temperature this can achieved only by good running.

Is case 380 tractor diesel or gas?

The Case 380 had a David Brown 3 cylinder liquid cooled diesel motor with a displacement of 2.7 liters.

Does a powerstroke have an alumminu block?

No. A Powerstroke, or any diesel engine in that case does not have an aluminum block. Diesel engines are made heavier duty to handle all the power and heat they create. All diesel engine blocks use a cast steel block. The new Ford 6.7L Powerstroke uses a new metal called Compact Graphite Steel which is much lighter and stronger that cast steel.

5 Is it possible to determine the form factor without opening the case?

The form factor can be determined without opening the case. The form factor can be established based on the shape of the case.

Does a dodge ram 3500 work with out a computer chip?

Well, depends on model year. Any model year before they introduced fuel injected engines, certainly. Current production ones... no. The engine depends on the ECM for a number of functions critical to its operation, which includes everything from adjusting air intake to aftertreatment operation (in the case of diesel engines).

How do you replace a diesel engine Chevy Caprice classic?

Whatever you do don't buy a junkyard diesel engine. The 350 car diesel was built off of a 350 gas engine at the time. So it did not work well and was very unreliable. I would suggest rebuilding your old diesel, or purchasing a new orre manufactured unit from GM. Theses routes will fix the common problems that made these engines hideously unreliable. GM basically killed most diesel engine car production with this unreliable engine. Everyone assumed every diesel was this bad. That is not the case, most other diesel's such as the Chevette 1.8 Isuzu diesel, and the VW diesel's of the time are very good. Hope I didn't sound preachy, I was just trying to help.
