What are the factors that affect the power output of an engine?

What are four factors of engine output?

The cycle includes four distinct processes: intake, compression, combustion and power stroke, and exhaust. Spark ignition gasoline and compression ignition diesel engines differ in how they supply and ignite the fuel.

What are the factors that affect the efficiency of automobile engines?

Some factors that affect the efficiency of automobile engines:

  • The efficiency of the automobile engine cannot exceed the. …
  • The engine block cannot be allowed to go over a certain temperature.
  • Any practical engine has friction, incomplete burning of fuel, and limits set.

What are the factors that affect petrol engine emissions?

Other factors affecting the emission rates are the speed, acceleration and engine load of the vehicle. Low speeds, congested driving conditions, sharp acceleration, deceleration, etc. result in higher emissions. On the other hand, intermediate speeds and low density traffic conditions cause lower emissions.

How is the power output of a diesel engine controlled?

Power output in diesel engines is controlled by varying fuel rate rather than by throttling inlet air as it is the case in conventional gasoline engines.

What are the three factors of engine good combustion?

Three things are required in proper combination before ignition and combustion can take place—Heat, Oxygen and Fuel.

What is the effect of engine position on performance of engine?

Having the engine mounted low down and in the centre of the vehicle shifts this centre of gravity, limiting body roll and improving handling balance. Another benefit to a mid-mounted engine is an increase of tyre grip under acceleration.

Which engine has more mechanical efficiency?

Real diesel engines are of course considered to be more efficient that Otto cycle engines; one reason being that diesel engines typically operate at higher compression ratio and the expansion ratio from even the later stages of heat release can still be considerably higher than that of most real Otto cycle engines.

What causes a car to fail emissions?

A rich air/fuel mixture will often cause a failed emissions test. This problem is usually a result of a defective oxygen sensor or faulty injectors. So, if you fail emissions, have these components inspected and changed if necessary. You have a loose or leaking gas cap.

How do I fix my emissions problem?

How to Fix Emissions Problems On a Car

  1. Check the air filter on the air cleaner system. …
  2. Inspect the Positive Crankcase Ventilation (PCV) system. …
  3. Examine the Evaporative Emissions Control (EVAP) system. …
  4. Go over the Exhaust Gas Recirculation (EGR) system.
