Carburetor prepares a mixture of air and fuel (which is suitable for combustion) for an spark ignition engine. Carburetor is also used to control the speed of the vehicle. It converts petrol into fine droplets and mixes it in air in such away that it burns smoothly in engine, without any problem.

Do CI engines have carburetors?

Fuel Chemistry

Diesel engines are also IC engines. However, in Diesel engines, there is no carburetor. Only air is compressed to much higher pressures and the fuel is injected into the compressed air. As the fuel and air are mixed, the fuel evaporates and ignites (hence called compression ignition).

Why carburetor is absent in CI?

As in the CI engine, only air is compressed and then fuel is injected into the cylinder by an injector. So the CI engine does not require the carburetor.

Which is not used in CI engine?

Why methanol is not used in CI engine? Explanation: Methanol is not used in CI engines because of its high octane number and low cetane number. Pure methanol and gasoline in various percentages have been extensively tested in engines and vehicles for a number of years.

Which fuel is used in CI engine?

Compression-Ignition Fuels. A compression-ignition engine is usually powered by diesel fuel and, recently, by biodiesel.

Which is the most preferred CI engines fuel?

engines fuel most preferred are aromatics while for C.I. engines fuel most preferred are paraffins.

Is fuel pump used in CI engine?

Early CI engines used air pressure to deliver the fuel into the cylinder, but nowadays liquid fuel, supplied by a reciprocating plunger pump, is delivered through small bore steel pipelines to the injector, which breaks up the fuel to the required degree and deliver it to combustion region in the chamber.

Why diesel engines are called CI engines?

The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to the mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine).

Why petrol is not used in CI engines?

When petrol is added to diesel it reduces its lubrication properties, which can damage the fuel pump through metal-to-metal contact and create metal particles causing significant damage to the rest of the fuel system.

What are the 3 types of carburetors?

There are three general types of carburetors depending on the direction of flow of air.
  • Types of Carburetors.
  • Constant Choke Carburetor:
  • Constant Vacuum Carburetor:
  • Multiple Venturi Carburetor:

Is Governor used in CI engine?

The governor's purpose is to control the fuel to the engine cylinders so as to control the speed of the unit, holding the speed constant for all conditions of load imposed on the generator conditions of load imposed on the generator being driven by the engine.

What are the main parts of a carburetor?

Components of carburetors usually include a storage chamber for liquid fuel, a choke, an idling (or slow-running) jet, a main jet, a venturi-shaped air-flow restriction, and an accelerator pump. The quantity of fuel in the storage chamber is controlled by a valve actuated by a float.

Is carburetor used in car?

All production vehicles today use computerized fuel injection systems to feed fuel and air into the combustion chamber of the engine. ... After that, you have to let the engine warm up. Otherwise, it simply won't run right. Carburetors on cars operated the same way.

Do all petrol engines have carburetors?

Most production carbureted engines, as opposed to fuel-injected, have a single carburetor and a matching intake manifold that divides and transports the air/fuel mixture to the intake valves, though some engines (like motorcycle engines) use multiple carburetors on split heads.

What is the full form of SI engine?

A spark-ignition engine (SI engine) is an internal combustion engine, generally a petrol engine, where the combustion process of the air-fuel mixture is ignited by a spark from a spark plug.

Which engine is more efficient CI or SI?

CI engines have higher Thermodynamic Efficiency

With a higher compression ratio in CI engines as compared to SI engines, CI engines have a higher thermodynamic efficiency since more work is done with each expansion stroke.

Is a diesel engine 2 or 4 stroke?

Diesel engines are 4-stroke, but they differ from their gasoline-powered counterparts in their method of combustion. Diesels rely on very high compression ratios to ignite the air/fuel mixture rather than a spark plug.

Why diesel engine has more torque?

In the diesel engine, the piston moves to the very top of the cylinder, so the stroke length is longer and as torque equals force multiplied by distance, we have more torque. In order to combust fuel, diesel engines use air compression and with faster compression rate the fuel burns faster thus adding to torque levels.

What does CI stand for in engines?

CI engine in Automotive Engineering

(si aɪ ɛndʒɪn) or compression ignition engine. Word forms: (regular plural) CI engines. noun. (Automotive engineering: Vehicle components, Engine, transmission, and exhaust) A CI engine is an engine in which the fuel charge is ignited by the heat of compression.

What is the meaning of SI and CI?

CI > SI. Simple Interest (SI) = (P×R×T)/100. CI = Principal (1+Rate/100)n - principal.

Why SI engines are high speed engines?

SI Engines operates at higher speed due to their less compression ratio (i.e. less weight per unit power). They produce less torque and operates at higher speed. But there is a limit up to which the speed can be increased.

What are the basic elements of CI fuel injection system?

Fuel Injection System Components
  • Low-Pressure Side Components. Overview. Fuel Tank and Fuel Supply Pump. Fuel Filter. Fuel Heaters & Coolers.
  • High-Pressure Side Components. Overview. High Pressure Pump. Accumulator. Fuel Injector and Fuel Injection Nozzle. Fuel Metering. Nozzle Needle Control Actuators.

What is the main purpose of fuel injection system in CI engine?

Abstract: The purpose of the fuel injection system is to deliver fuel into the engine cylinders, while precisely controlling the injection timing, fuel atomization, and other parameters. The main types of injection systems include pump-line-nozzle, unit injector, and common rail.

Which stroke engine is used in cars?

The four-stroke engine is the most common types of internal combustion engines and is used in various automobiles (that specifically use gasoline as fuel) like cars, trucks, and some motorbikes (many motorbikes use a two stroke engine).
