Air in an internal combustion engine has 227 C 1000 kPa with a volume of 0.1 m3 Combustion heats it to 1500 K in a constant-volume process What is the mass of air and how high does the pressure?

Considering R of air = 0.287 kJ/kg.K
Pv=mRT
1000kPa * 0.1 m^3 = m * 0.287 * 500K
m=0.697kg
for T=1500K
P=3000kPa

What is diesel combustion pressure?
The diesel combustion pressure depends on various factors. The model and the type of diesel engine is important.
Why is diesel is an internal combustion engine?
When air is compressed it becomes hot. A diesel engine compresses air and fuel in a cylinder. The mixture burns and pushes down the piston. It is called an internal combustion engine because engines that work by burning fuel inside a cylinder and pushing down a piston are called internal combustion engines. Steam engines are external combustion engines. The fire burns and heats water in a boiler. The water turns to steam and either drives pistons like in a steam locomotive or in a turbine. Gas turbines could technically be called internal combustion but are not. One turbine compresses the gas. The gas burns under pressure in a combustion chamber and turns another turbine. Jet planes and a number of electric generators use gas turbines.
What does a PVC do and what does it stand for in an internal combustion engine?
PVC - Positive Crankcase Ventilation. Used to allow the engine to vent out pressure that is creates while operating. Generally it is vented back into the air intake system after the air filter to get "burned" in the combustion chamber.
Why dual combustion cycle is called as limited pressure cycle?
In dual combustion cycle heat is added at constant volume which increases the efficiency of cycle, whereas heat addition at constant pressure limits the maximum pressure of the cycle.
What does the internal combustion engine work?
rising piston compresses air/fuel mixture , then ignited at top, heat raises pressure, pressure on piston crown creates force, force over stroke = work
What is the role of the boost gauge in an internal combustion engine?
A boost gauge in an internal combustion engine has the role of a pressure gauge. The gauge indicates the manifold's air pressure or a turbocharger or supercharger's boost pressure.
What is fuel rail pressure control valve?
The main function is to spray atomized fuel into the combustion chamber of an internal combustion engine.
How are internal and external combustion different?
In terms of engines, an external combustion engine such as a steam engine burns fuel outside of the pressure cylinder used to drive the piston. An internal combustion engine such as a petrol or diesel engine burns the fuel inside the pressure cylinder used to drive the piston.
Difference between internal combustion engines and steam engines?
Internal combustion engine is where the fuel is ignited in the cylinder to make the piston move, petrol or diesel. A steam engine has an external pressure vessel to supply the steam to the cylinder to push the piston. the is no combustion in the engine as such.
The change in internal energy for the combustion of 1.0 of octane at a pressure of 1.0 is 5084.1 If the change in enthalpy is 5074.3 how much work is done during the combustion?
-9.8 kJ
Diagram of engine combustion?
In density and pressure by both the internal combustion spark done with the heat in the atmosphere combustion.
What is an external combustion engine?
An external combustion engine is one in which the oxidation of the fuel occurs outside the engine, which provides heat to the motive portion of the engine. External combustion is characterized by burning the fuel outside of the moving parts, as opposed to burning fuel inside the cylinders of an internal combustion engine. The Steam engine, using steam pressure, is an example of external combustion, as in the "Stanley Steamer," an early motorcar; and in steamships The combustion is in the boiler, not in the cylinders that convert steam pressure and volume to mechanical work. Internal combustion engines include diesel and gasoline vehicles (explosive fuel mixes), gas turbines, and most jet aircraft engines.
How are internal combustion engines and external combustion engines alike?
Essentially, they are the same, pressurised gas in a closed cylinder forcing a piston along which turns a crank via a con rod converting linear to rotary force. The main difference is how the pressurised gas is delivered: In an internal combustion engine, fuel and air are sucked into the cylinder, valves are closed, fuel/Air is ignited, combustion takes place, heat makes pressure. So the pressure by combustion is created inside the cylinder (internally) In an external combustion engine, the gas is pressurised prior to entering the cylinder, in the case of a (piston) steam engine, water is boiled (by coal or other fuel combustion) in a closed container (boiler) to create pressurised steam, which is then delivered to the cylinder under pressure. So the pressure by combustion is created outside the cylinder (externally)
Would a normal combustion engine work on Mars with oxygen injection?
No. The atmospheric pressure is too low. Perhaps an internal combustion engine could be designed to operate on Mars, but it would not be 'normal.'
What is diesel combustion pressure?
The diesel combustion pressure depends on various factors. The model and the type of diesel engine is important.
Why do water move into a apparatus of combustion?
Water does move into the apparatus of combustion because of the reduced pressure.
What is humming in gas turbine?
The formation of combustion oscillations can occur during an operation of a gas turbine burner. This is also known under the concepts of "combustion chamber humming", "combustion chamber oscillations", "combustion-induced pressure pulsations", "oscillating combustion processes". The combustion oscillations are due to an interaction between the quantity supplied per unit time of combustion air/fuel mixture flowing in the flow duct of the burner. The mixture is ignited after entry into a combustion chamber and burns in a flame, with the momentary combustion conversion in the flame. Combustion conversion designates the quantity of combustion air/fuel mixture converted per unit time during a combustion process in a flame. Pressure fluctuations in the combustion chamber, which can lead to the formation of a stable pressure oscillation, can occur due to a change in the combustion conversion. In addition to an increased production of noise, the combustion oscillations cause an increased mechanical and thermal load on walls associated with the combustion chamber and on other parts belonging to the combustion system.
