In a diesel engine, the air pressure during the compression stroke can reach around 30 to 50 psi (pounds per square inch), but it can be significantly higher in some high-performance engines, sometimes exceeding 100 psi. This high pressure is crucial for achieving the necessary temperature to ignite the diesel fuel, as diesel engines rely on compression ignition rather than spark plugs. The compression ratio in diesel engines typically ranges from 14:1 to 25:1, contributing to the high pressures observed.

What are the strokes in a two stroke diesel engine?

suction stroke and exhaust strokes are the two strokes involved in 2 stroke engine....


Why two stroke engine not used in aircrafts?

In the two stroke petrol engine as you know suction,compression,ignition,expansion and exhaust is completed in only two stroke and one revolution of crank wheel more over diesel ignites at very high pressure which is not the same in case of petrol........if petrol is also ignited under pressure it explodes producing a big thumping sound.called KNOCKINGthis may reduce the power output and also lead to breakdown of the engine. For the above reason two stroke engine cannot compress air and ignite the fuel like diesel engine.


How does a Bollinger engine work?

The engine is a 2 stroke 'semi' diesel. Inlet and exhaust are as per 'normal' two stroke diesel but the injected fuel is not ignited by compression alone as in a normal diesel. Instead a 'hot bulb' on the cylinder head is heated with a blow-lamp before starting and heat from this, transferred to a tube in the combustion chamber which ignites the fuel to start the engine. Once running the engine itself maintains the temperature. Often called a Hot Bulb Engine.


What is the purpose of camshaft in the diesel engine?

The camshaft operated the inlet and outlet valves in the cylinder to admit fuel to the engine before ignition and expel the exhaust gas after the power stroke. The camshaft operates at half the crankshaft speed in a four-stroke engine.


How do you distinguish between a petrol engine and diesel engine?

A diesel engine is an internal combustion engine which uses the heat of compression to ignite the fuel/air mixture in the third stroke of the 4-stroke cycle, while the petrol engine is an internal combustion engine which uses an electrically-generated spark system to do the ignition. Diesel engines have a higher efficiency compared to petrol engines. In simple terms this means diesel engines can give 50% or more miles per gallon than petrol engines.

There is no spark plug in a diesel engine then how does fuel burn in it?

Fuel is injected into the combustion chamber in the form of a sprayed gas and when compressed under great pressure it spontaneously explodes creating the power stroke in a 4 stroke diesel engine.

Where is Oil pressure sender on 1996 7.3 power-stroke diesel?

On a 1996 7.3 Power Stroke diesel engine, the oil pressure sender is located on the driver's side of the engine, near the rear, just above the oil filter. It is typically mounted on the engine block and can be identified by its wiring connector. To access it, you may need to remove some components for better visibility.
