on what factors is fuel efficiency of a motor engine depends?

A certain amount of energy is lost to the auxilliaries such as the water pump, fuel pump, oil pump and fan. In general for a two cylinder engine, each rotating part (cam, crankshaft, ect.) there are three bearings for part.
With four cylinders, you add little if any energy loss because of the auxilliaries and you will probably only add one additional bearing for cylinder.
The result should be a very very slight increase in efficiency.

Yes. The fuel efficiency of a motor engine depends on maximum usage of the fuel burning energy. 4 cylinder engine use the fuel power more effectively than a 2 cylinder engine.

Four cylinders will use twice the fuel as two cylinders of the same size and reduce fuel efficiency of the engine. However, if using four cylinders lets you carry a much heavier load (four times as much?) or saves time (by moving twice as fast or twice as far in a day?) then the vehicle is more fuel efficient. A motorcycle gets much better mileage (mpg) than a sedan but the sedan can move the entire family, right?

if u mean Fuel efficiency as total distance travelled per litre of petrol or diesel then definately Fuel Effciency decreases...
as u keep on increasing the cyclinder, the Power of the Vehicle increases but it consumes more fuel..
thats why a motorbike is more Efficient than a Sedan
but Fuel efficiency can also be defined as Total power developed per liter of Fuel , then
increasing the cyclinder help in better torque management (there is lot fluctuation of torque in a single cyclinder , )hence fuel effiency increases if u increase the cyclinder...
so its up to u , which fuel effiency u want to go for.......

properly maximum states placed ethanol of their gasoline on the 1st of November, which cuts my mileage down by ability of approximately 80 miles a tank. i might substitute your air filter out to boot if it have been given moist, your vehicle is ravenous for air, sorta like working with the choke on. different than that, i might take it into some place. a million. an entire music up. 2. examine all your digital sensors 3. Run test codes on it at a vehicle fix save/broking 4. in the journey that your engine stalled interior the water, become it with the aid of ignition shorting out, or did you hydro lock your engine? in the event that they replaced the laptop controls, perhaps they did no longer set something suitable on your particular engine?... or something of that variety? Too many variables it could be, if it become me, i might pay the broking 75 to one hundred dollars to examine fault codes fairly than the mechanic on the interior of sight storage. another sensors may well be undesirable, or went undesirable with the aid of being under water to boot.

it depends on the efficiency of design of the whole motor... not the number of cylinders ...so, the fuel management system, the cam lift and duration, the shape and efficiency of the combustion chamber, size and stroke of the pistons...

Many factors.
Power to weight ratio, purpose of the vehicle, gear ratios, volume ( eg : two large pistons can have more volume and power than 4 small pistons ) bore & stroke, design of the engine ( by whom, how much expertise ,experience and research & development ) and many more.

nope
more culinder can make more uniform torque in a turn, and burning fuel can be controlled easily

yes
the rate of fuel bured per revolution of the motor engine
