Does a diesel engine have a cylinder head?
A diesel engine’s cylinder heads perform several functions. First, they provide the top seal for the cylinder bore or sleeve. Second, they provide the structure holding exhaust valves (and intake valves where applicable), the fuel injector, and necessary linkages.
How can you tell the difference between petrol and diesel?
Diesel or petrol car: How can I tell?
- Look for a sticker. Rental companies often put stickers in different places around the car to tell you which fuel to use.
- Check the model name. There might be a clue on the back of the car itself.
- See if the fuel pump will fit.
Why diesel engine has more torque than petrol?
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 is the purpose of a cylinder head?
They’re key to controlling air flow in and out of the cylinders and fuel deployment. The cylinder head also holds the injectors and valves – and contains more moving parts than any other part of the engine. Although largely unnoticed, the cylinder head plays a key role in your engine.
What is a diesel cylinder head?
The cylinder head is going to have your intake valves, your exhaust valves, and it’s also going to house your fuel injector down through the center. The head sits on top of your engine and is essentially the control center for your combustion chamber.
Which engine is faster petrol or diesel?
Though the diesel variant has a higher torque than the petrol, it does so on a lower rpm due to which shifting is necessary sooner than that on the petrol. Thus the petrol produces more power and accelerates from 0 to 100 quicker.
Which is the common component between petrol and diesel engine?
4.6
| SI engine (Petrol Engine) | CI engine (Diesel Engine) |

| A carburetor is used to atomize, vaporize and meter the correct amount of fuel according to the requirement. | Fuel injection pumps and atomizers are used to inject metered quantities of fuel at high pressure according to the requirement. |
Which of following option is correct when diesel is compared to petrol?
Solution(By Examveda Team) Per litre, diesel contains more energy than petrol and the vehicle’s engine combustion process is more efficient, adding up to higher fuel efficiency and lower CO2 emissions when using diesel.
What is the difference between a petrol engine and diesel engine?
The main difference between a petrol engine and a diesel engine is the fact that a petrol engine uses spark plugs to initiate the combustion process, while a diesel engine uses the heat of compression to self-ignite. Furthermore, petrol engines tend to run faster than diesel,…
What are the advantages of a diesel engine?
Diesel engines tend to have various advantages over other internal combustion engines, including: They burn less fuel than a petrol engine to do the same amount of work. They can convert over 45\% of the fuel energy into mechanical energy, while petrol engines can only convert 30\%. This results in a better mileage.
What is the working principle of a petrol engine?
The air and petrol are mixed in the carburetor before they enter into the cylinder. The fuel is fed into the cylinder by a fuel injector and is mixed with hot compressed air inside the cylinder. 3. The petrol engine compresses a mixture of air and petrol which is ignited by an electric spark.
How 4 stroke petrol engine works?
A Petrol engine may be of two stroke or four stroke type. But four stroke engine is most commonly used because of its better efficiency. Let’s understand the working of the four-stroke petrol engine. Suction Stroke: The piston moves downward and the air petrol mixture enters into the cylinder.
