Q & A

What is a hydraulic system?

A hydraulic system is a system that uses incompressible fluid to transmit force for moving heavy objects, such as a hydraulic jack used in automotive applications.

What is the principle behind the working of hydraulic systems?

Hydraulic systems work based on Pascal's Law, which states that pressure applied to a fluid in a closed system is transmitted equally in all directions.

What is one key advantage of hydraulic systems?

One key advantage is that hydraulic systems can handle very heavy loads due to their ability to generate high pressure.

What is a major disadvantage of hydraulic systems?

A major disadvantage is their susceptibility to contamination by dirt, which can weaken the system and cause malfunctions.

What kind of fluid is typically used in hydraulic systems?

In hydraulic systems, incompressible fluids, often oils, are used to transfer pressure and force effectively.

What is a 'full M M freezer m' in the context of hydraulic tools?

A 'full M M freezer m' is a tool used in automotive systems to measure the fuel pressure in the high-pressure fuel lines between the pump and injector.

What function does an 'injector tester' serve in automotive systems?

An injector tester is used to measure the pressure and volume of fuel released by an injector, ensuring that it is functioning properly without leaks.

What is a 'nozzle tester' and what does it do?

A nozzle tester is used to check the quality of a fuel injector nozzle by testing for leaks and ensuring proper spraying of fuel into the combustion chamber.

What are some disadvantages of using hydraulic systems in terms of maintenance?

Hydraulic systems are complex, requiring specialized maintenance, and they can be costly to maintain due to their intricate construction and sensitivity to temperature changes.

Why can't hydraulic fluid perform optimally at high temperatures?

At high temperatures, hydraulic fluid can lose its effectiveness, causing the system to malfunction or not function optimally due to the fluid's reduced viscosity and potential for thermal degradation.
