What Are The Types Of Piston Rings?


Types of Piston Rings:

  • Compression rings. Counter bored and scraper rings. Headland rings.
  • Oil control rings. One-piece slotted cast iron type. One-piece pressed steel type. Three-piece steel rail type with an expander.



What is the brake power?

the ability of a braking system to cause a vehicle to come to a halt. If it anticipates an unavoidable collision, the system retracts all slack from the seatbelts and increases braking power. Collins English Dictionary.


What is crankshaft made of?

Crankshafts are made from forged steel or cast iron. Crankshafts for high-volume, low-load production vehicles are generally constructed from nodular cast iron, which has high strength (see Appendix D). Fuel-efficient engines require a high power-to-displacement ratio, which has increased the use of forged crankshafts.


What is the function of engine cylinder Mcq?

Explanation: The two primary functions of the cylinder is to act as the combustion chamber in the engine and to guide the piston movement. The crankshaft's function is to transfer rotary motion.


Is a heart a motor?

Our working hypothesis is based on the dichotomy motor-brake: the cardiac muscle can act as a motor, when shortening against a load, or as a brake, when lengthening to a load. We discuss our hypothesis by means of a lumped model of the left heart, where both chambers are considered as hollow spherical shells.


What are the types of piston rings?

Types of Piston Rings:

  • Compression rings. Counter bored and scraper rings. Headland rings.
  • Oil control rings. One-piece slotted cast iron type. One-piece pressed steel type. Three-piece steel rail type with an expander.


Is petrol is used in diesel engine then?

Explanation: Petrol is not used in diesel engine because if petrol is used in a diesel engine, then higher knocking will occur.


What is IP in diesel?

It is reported that some South African diesel is contaminated with dirt and has poor lubricity, given that some fuel has been spiked with paraffin (IP), thereby making the fuel appear cheaper and lighter.


Which is the power developed in an engine Mcq?

Explanation: Brake power is defined as the power developed by an engine at the output shaft while indicated power is defined as the total power developed by combustion of fuel in the combustion chamber and mean effective pressure is defined as the hypothetical pressure which is thought to be acting on the piston


What is meant by fuel rating?

An octane rating is simply a measure of how heat resistant a fuel is in order to prevent knocking. In other words, octane doesn't enhance combustion — it prevents the air-fuel mixture inside an engine from igniting before it's supposed to. The higher a fuel's octane, the more resistant it is to knocking.


Which is used in CI engine Mcq?

Diesel Engine Principle MCQ Question 1 Detailed Solution

SI engineCI engine
Petrol is used as fuel.Diesel is used as fuel.
A petrol engine draws a mixture of petrol and air during the suction stroke.A diesel engine draws only air during the suction stroke.


Which is the heart of engine?

Is The Crankshaft The Heart Of The Engine? In an engine, there is just one link; its crankshaft acts as a strong linchpin. It's the link between the Piston and cylinder that gives it power to move.


What is compression ratio in IC engine Mcq?

Solution(By Examveda Team) Compression ratio of I.C. Engines is The ratio of volumes of air in cylinder before compression stroke and after compression stroke.


When was the first engine made?

The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860 and the first modern internal combustion engine was created in 1876 by Nicolaus Otto (see Otto engine).


Is called the heart of an IC engine?

In the motor engine, the cylinder remains motionless during each work- ing cycle. On the contrary, in the heart it is the cylinder (Fig.


Which is used in internal combustion engine as fuel Mcq?

Internal Combustion Engine MCQ Question 4 Detailed Solution

The correct answer is Ghee.


What is swirl in CI engine Mcq?

Answer & Solution

In compression ignition engines, swirl denotes a Rotary motion of the gases in the chamber. In compression ignition engines, swirl denotes a rotary motion of the gases in the chamber as swirl is always related to rotary motion.


Who invented the internal combustion engine Mcq?

Explanation: The compression ignition engine is also known as the Diesel engine and it was invented by Rudolf diesel in the 1890s. Nikolaus August Otto invented the SI engine.


On which cycle the CI engine runs Mcq?

Explanation: Otto cycle: The air-standard-Otto cycle is the idealized cycle for the spark-ignition internal combustion engines. Otto cycle is the one which has two constant volume heat transfer processes and two adiabatic work transfer processes.


What is the normal range for a pulse oximeter reading?

A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone's blood. If your home SpO2 reading is lower than 95%, call your health care provider.


Is the reciprocating part of IC engine?

Reciprocating internal combustion engines are devices that convert the chemical energy contained in a hydrocarbon into mechanical energy (rotation of a shaft with a certain speed and torque) and into the thermal energy of the waste gases that escape into the atmosphere.
