VE is a measure of cylinder filling and exhausting to show potential increase or decreased horsepower. Higher VE increases horsepower. VE changes through the rpm range and for racing applications is optimized for the upper rpm range with a sacrifice of VE in the lower rpm range. Things like camshafts and rocker arms, intake ports and length, carburetors, combustion chamber type, valves position and size, exhaust ports and length, header size and length all effect VE.

What are the causes of reduced volumetric efficiency?
Reduction in power density. Power density is the power produced by the engine per volume unit. Reduced volumetric efficiency means that less air/fuel will be delivered to the engine for a specific engine volume.
What is a turbo charger volumetric efficiency?
Turbocharger volumetric efficiency refers to the effectiveness with which a turbocharger can compress and deliver air into an engine's intake system relative to the engine's displacement and operating conditions. It is a measure of how well the turbocharger fills the engine's cylinders with air, impacting the engine's power output and performance. Higher volumetric efficiency indicates that the turbocharger is effectively increasing the amount of air, thus allowing for more fuel to be burned and improving overall engine efficiency. Factors affecting volumetric efficiency include the design of the turbocharger, engine speed, and the temperature and pressure of the intake air.
What is the advantage of using variable length inlet manifolds?
Maximizes torque/power out of the engine by increasing cylinder filling (volumetric efficiency).
What is the volumetric efficiency mechanical?
Volumetric efficiency in mechanics refers to the actual volume of air-fuel mixture drawn into the cylinder of an internal combustion engine compared to the theoretical maximum possible volume. It is a measure of how effectively the engine can fill its cylinders with the air-fuel mixture during the intake stroke. A high volumetric efficiency indicates better engine performance and power output.
Which diagnostic test determines if there is a volumetric efficiency problem?
The diagnostic test that determines if there is a volumetric efficiency problem is a dynamometer test, often used in automotive diagnostics. This test measures the engine's power output and compares it to the expected output based on its specifications. A significant discrepancy can indicate issues with volumetric efficiency, such as poor airflow, intake restrictions, or exhaust blockages. Additionally, tests like manifold pressure measurement or airflow analysis may also help identify related problems.
What is the ratio between brake horse power and energy supplied?
Brake Thermal efficiency !!
What factors effect the speed of the car?
Aerodynamics, horse power, gear ratio,
What is the effect of clearance volume by increasing or decreasing in a PD compressor power?
clearance volume decreases the volumetric effienfy of compressor.the clearance volume should not be too less or too more.
Does changing the tire height affect anything?
It will effect the accuracy of the speedometer and odometer, effect the transmission shift points, effect the fuel mileage, effect the brake horse power,
Will the improvement of power factor will increase the efficiency?
Efficiency is defined as the ratio between the output power and the input power of a machine, expressed as a per unit or percentage. Power factor improvement has absolutely no effect on the behaviour of a load. All it does is to reduce the magnitude of the load current. A reduction in load current means that less copper can be used in the supply of energy to the load. However, it doesn't effect either the output or input power of the load. So the answer is no, power factor has no effect on the efficiency of a load. You could argue, however, that if improving the power factor of a load reduces the supply current, leading to lower line losses, then there is an improvement in the efficiency of the supply system.
How much horse power is in 1100cc snowmobile?
Not enough information. Is it turbocharged? Is it a piston engine? What type of fuel does it use? If you know its rate of fuel use and its efficiency you can find the power produced.
Which valve is larger in an ic engine?
In IC engine, the inlet valve is always larger in diameter as compared to exhaust by 20-35 % in dia. to improve the volumetric efficiency and to achieve good power and performance even at high speed by overcoming the blow losses.
